you can also consider going to a 3D program that's not like pulling a bowling ball through your ears. A real 3D app like C4D, or maya. Like they don't slow to piss and back. Sorry but blender is only for people that like mediocrity.
Just one question, can we all have a look at your work?? I sincerely hope that its not mediocre.
Artstation link will work for us.
Don't know about maya, but c4d still crawls my nightmares with its way of handeling foliage. You also have to use proxies there, the same way you have to do here, or else everything is even more sluggish than here
Or people like me who can't afford a pricey ass subscription fee'd program that would cost you an arm and a leg JUST to use it. Blender might not be the best program compared to what you brought up, but at least it's free!
It really depends on what you want to do, some people have several programs, they might use c4d for scene arrangement and another program for modeling. But really I don't care what you think since you're ignoring an amazing open source free program that is better at some things then many commercial apps. Can any program be the best at everything?
All 3D software behave the same with this amount of polys in the viewport, even if instanced.
3 minutes in and this got to be the best video in blender I've seen this year.
This is such an INSANE workflow, thanks!!
Thank you so much. I saw this video a while ago when it premiered and right now I'm working on a project that was giving me hell because of the polycount. This technique came to the rescue.
By far the best tutorial that I have seen in a long time. Very easy to follow. Thnk you for this!
Probably the best video with Geo nodes i ever seen, thx alot!
Nicely done and very useful. Thank you.
Im really putting my focus to creating 3D scenes and 2D renders and this is such a gem for simple tips I need to look out for!!
You covered so much all the way around in such a simple and complete task you set out to make!!
Amazing tutorial, quick explanation, this was one of the best tutorials i have ever watched!
Wonderful tutorial, very well explained!
Great tutorial, very clear, nicely paced and to the point.
Okay this was something that I needed, thank-you so much for this tutorial ❤ you earned a sub!
Great stuff! If Convex Hull still produces too much geometry one can always choose for Bounding Box instead of CH.
thanks
I ended up using bounding box because I hadn't thought of convex hull. Always something to learn with blender3d
You can use a triangle instead of a bounding box. See which one is faster.
Or a billboard of the tree.
That is acctually really useful. I never thought of using gemetry nodes for that
Awesome tutorial, ill definitely be using this on my next project
Fantastic technique! Thank you for the tutorial! 🧠💥
Great resource! Thanks for sharing.
OMG! This is soooo helpful! Thanks a lot for this amazing tutorial
Awesome! I really enjoyed your vid thanks for sharing.
great explained, I appreciate your patience in explaining step by step, especially on geometry node ... nice ...
This is the best free software Ive seen. Respect.
Thank you for the trees very much appreciate you putting a download link.
I really like this approach more than the outlines of collection instances since this shows the geometry. Thank you very much for sharing!
Great work. I will try this out
Helps a lot to understand geometry nodes
good channel with amazing stuff, I'm with you now 😀
That's pretty darn smart! Thanx 4 sharing! :)
Thank you. Great explanation.
Extremely helpful, thank you
Great information, thank you!
This is awesome. Thank you.
Great explanation!
Great tutorial!
Super helpful, thank you!
You saved stress to people, thank you!
very very good! i really enjoyed and wowd at the same time because i am used to work with proxies from 3ds max but now i have a better solution for that in blender!
Thanks from heart.really helpful
bro thank u very much i can not explain how happy i am thank you
Man this is quality video!
Thanks, learned a lot from this
Gained a subscriber. Excellend tutorial Hayden.
Literally Thank you so much
That is so simple, yet so smart, I'm ashamed I haven't thought of this 😅
Awesome, thank you for teaching! Guess I'm gonna have to test it out for myself, but I'm curious what the render time on an image like that is. With optimized settings, is it comparable to a detailed portrait render or whole other level (with all those little tree details)?
Thank you! So helpfull 💚💚💚
Great video, keep it up
ITS REALLY WORKED LOL THANK YOU DUDE
Thank you it works with me
omg dude i love this, big thanks and kiss
For organizational purposes, the top of my outliner has an IMPORTS collection, which consists of collections of imported curves (say, different floors and ceilings), helper geometry, and a __DUMMY VERT which is just a single vert I can use to store materials for easy access, or geometry node groups. Followed by collections for SOURCES (used for instances) and CAMERAS and so on. In this case where I'd want to re-use the same setup, I'd put the convex hull and switch stuff into a node group I then make accessible in the __DUMMY VERT object. Maybe I want to examine how things look in the viewport, I just select this object and enter its node group and toggle the switch from inside. Maybe you set the trees to non selectable, now you still have access to this control without any additional hazzle. I do the same thing for material nodes, where I put adjustable global controls in the world shader for easy access. The variables you want global control over, say the switch in this case, you don't want to expose/promote.
@gottagowork Please create a short video showing all this in action. I get it, but better to SEE.
@@funw3d538 It's not so much to see or create a video about. I'm not a video/tutorial creator, and that approach says "...this is how you..." too much. The takeaway is trying to stay organized in a way that makes sense for what you do. It will pay off when projects grow in complexity. How I organize my outliner may not even be relevant to anybody else's line of work, or others use it even smarter than myself. A studio might even have guidelines on this.
very nice
Beautiful! Just wondering how you did the underwater for the final render? I followed the water tutorial but it doesn't look good without a sea floor/bottom.
Love this tutorial! This method is brilliant and I am looking forward to trying it soon. I had a question on the particle placement. You ran a node to make it split by height, which makes complete sense for the scene, is it possible instead to use a map, like a black and white map of some sort, to tell it where to and not to place the new trees? I know I could probably do it with weights, but I am going to use this on an architectural render, and want to use a processed aerial image to tell blender to put trees where there are actually trees.
Thanks! That should work using the image texture node luminance to drive the density of the distribute points on faces node.
@@HaydenGray I solved my issue! In case anyone wants to know how to do this without driving the actual density, this page shows you how to do it: blender.stackexchange.com/questions/247312/using-an-image-node-as-point-distribute-density-in-geometry-nodes Essentially, you delete points after generation and before instancing, using your created image to drive the deletion. Be sure to set your uv map on your image node. To learn how to do that, this video: blender.stackexchange.com/questions/247312/using-an-image-node-as-point-distribute-density-in-geometry-nodes between 0:46 and 1:10 will explain how that works right now.
Original Rep[ly:
Thanks for the suggestion, I have spent the day working on this, and have run into two issues. First, I can't find any node that will let me use Luminance. So I am unsure how to implement that. The second issue is that using a texture to drive density (instead of selection on the Instance node) cranks the density of the trees up so high that blender crashes. I've tried tweaking the image, but noting seems to get the density down to an acceptable level. For the geometry I am using, I have added a multiplier to the density, making it 1*.0001, just to get the density down to a level that does not kill blender all on its own.
thanks!
Note: You need to enable the *Copy Attributes* add-in to copy the Geometry Nodes.
Extraordinario
Wow,, thanks
I wonder if there is a way to tell if the renderer is Cycles or not, so that the wireframe, solid, and preview viewport types and viewport overlay use the convex hull, while the actual ray tracer uses instanced geometry, which is much faster to render in ray traced render engines with a BVH like Cycles than it is to do in raster engines. This would allow basically emulating that trick where one shows all the particles but disables the viewport overlay to get good performance while seeing the whole scene, while not requiring that the viewport overlay is disabled entirely.
How do you make your water go from greenish to blue? followed your other tutorial and end up with a almost all dark blue water
thanks
Does this directly mean the tree model loads once, but then translated hundreds of times via random positions? So useful method.
I was thinking this would be about how to render those huge environments so it doesn't take you weeks for a single frame ;-)
Hi, this is a great tutorial. For some reason in Blender 4.0.2 when I add the boolean (aka: "Set Proxy") to the group input it's using a checkbox to turn on/off rather than having the ability to increase/decrease using the arrows in your example. Is there a way for me to use the increase/decrease using the arrows like yours? Thanks for your time.
hey i want to ask, i use bagapie for this method, although the viewport is fast but the play in time line is still slow.
How can I get that HDRI you have? its really smooth and looks cool
It's the Nishita Sky Texture, you can have it inside blender in the world properties
And here's my next question.
How to make it faster render performance in "final render", not just in the viewport?
just choose bounds from properties,maybe assign a short cut so u can change to the original on the go
im no blender wizard but instead of a convex hull you could probably swap it out with a billboard in the viewport
Technically these are not actual proxies: the original geometry is always loaded into memory with these method. Blender has not an actual proxy system unfortunately.
Anyway this is the way to handle these scenes.
You’re correct, technically this is an LOD system that changes LOD at render time but in this case, it works very similarly.
This is an awesome technique but i wanna ask you one question "will this technique decrease my render time?"
It won’t decrease your render times but it will help you add complex geometry while keeping Blender running well.
So what resources do you use to create the trees themselves?
couldn't you just create instances instead and put all trees in a collection so you can click one button to hide them and work on your scene in render mode if you must until you want to see them all rendered? Even then they are all just data copies and not separate objects so maybe that could speed up the viewport. ? I don't know. Basically you are just turning the trees off, essentially to a blob so why not just hide them all? anyway, don't pay me any attention. I only started trying to learn 2 weeks back. thanks for the example of how to populate trees and still see where they are w/o killing your viewport.
I thought it was something gonna be like low polly from the far view and switched to detailed when camera gets closer, just like it happens in games for the optimization..
additionaly, adding a camera culling system to the tree geonodes would help performance as trees outside of the camera view are removed/ prevented from instancing
does this also work with procedual trees that is made by nodes? i cant seem to make it work
Are you using a Mac? What kind, your performance is good.
How you scattered the rock in edge of the surface i try to do that but i can't 😢 did you do video that
"You have a huge scene, it's all wonderul and then you add the foliage..." At that point I knew I was at the right place.
when doing the first part and pressing the switch my tree disappears and is not seen in the rendering
edit: fixed it already, great video, thanks
can you use this in Evee too ? I havn't really used geometry nodes that much
I laughed to hard as I share your pain with foliage :)
Is Viewport not working when I go to rendered mode, still shows the convex hull.
why cant they just make a "tick box" for the switch node group input? So it's not 0/1? Its already built in in the node...
but how to show full original mesh in cycles interactive...that is big question
how did you make it lighter colour around the edges/shoreline and show depth in the water? at 10:23
That’s a volumetric effect. Since the water is not just a plane and instead is a solid, it allows the light to scatter and have the appearance of depth
Wow
What are your computer specifications...pc mac or lappy
Ok... And how to override the method vertex paint?
bro. i need to know how to implement this with SCATTER 5!!!
its a pain to select each tree one by one and clicking enable. Real scenes have more than 3 trees. I'd leave that boolean value inside GN, without declaring it as GN input value, so i can convert all the Tress to proxies in GN itself by a single click on boolean node.
Object just disappears when I switch node to Convex hull. Why is this happening?
finally found
Where is the first scene from?
Did you just turn Blender into Clarisse?
Is it works like Gscatter ?
That thing is called viewport proxy, not render proxy. Render proxy only loads in the render engine of a raytracer, they are already prepared for that an load fast. The are not part of the scene, except a place holder. Not exist currently in Blender.
It works well, but here it’s where blender shows its limits.
Hi. I made a huge scene and the render alaways crash. If I use this method, it will render? Thankyou.
This technic is only to keep the viewport performances high, you may want to try frustum culling (th-cam.com/video/KoLF99PFLFM/w-d-xo.html) and level of detail (aka LOD) technics
Thanks a lot! Is actually what I need. I never heard about LOD!
LOD
3:00
I dont have Greater Than node ?
The actual node is the “Compare Node” with the “Greater Than” option selected.
@@HaydenGray Holy shiet, Yes!
Thank you, now my potato PC can handle large environments
_But what PC would you reccomend?_
@@avatr7109 For Blender it's enough to have Ryzen Threadripper with Nvidia Rtx 3090 ti
@@canyongoat2096 you don't need a 3090 ti lol. I ran Blender with a 1080 back in the day. You're limited in terms of extreme complexities but if you're starting off a 3060 will do you just fine. If you're thinking about getting into more serious creations you will want to max out power and capabilities where you wallet can handle it.
Thank you for your work, but you really should upload this in 4K, my eyes hurt to read fonts on the video.
