- Speedtree is a very powerful piece of software but it turns out you can create some of the same generators inside of Houdini including a Speedtree style grass generator.

awesome. mess up on the part to actually use it as input but got it working now rotations, another digital asset on my library! Thank you.
Glad I could help. I'm working on some other cool stuff so stay tuned
Great video, thanks very much!
Glad I was able to help
It's a good tutorial, simple and easy!
I highly recommend Rohan Dalvi's tutorial about generating grass
About auto-uv's: Is it possible to Unwrap a grass blade and scatter it, but keep the UV's perfectly overlapped? I want to apply 1 texture and just replace the UV correctly in Blender to match the texture.
Absolutely. If you want to use blender to set up the uv's just make one blade and export that. Then set up the uv's and reimport the model into houdini and scatter the one with uv's.
@@InsideTheMindSpace Dude, you are a LIFE SAVER. I've tried to figure this out for 2 days, and this was soo simple! I really appreciate it! :)
Glad I could help. Good luck with your project
Hi, your tutorials are very helpful bro, thanx. Can you make a tutorial - a car crashing to a wall or something like this?
Happy to help. I do have some plans to work through some simulation type effects but I am going to finish the projects I am working on first.
@@InsideTheMindSpace Thanx bro.
how can it be dynamic or interactive with other object?
That would be a more advanced technique that is out of the scope of this tutorial.
@@InsideTheMindSpace Love the breakdown any (new) plan to show how to make this interactive with other objects?
@@theodoredaley2229 Are you looking for interactive as in placement or in terms of the grass blades deforming around objects?
@@InsideTheMindSpace Deforming, so say you had a ball roll through it, or a character.
@@theodoredaley2229 At some point I absolutely want to cover that. I haven't been able to achieve something I am fully happy with yet. Its a topic I come back to periodically with fresh eyes
Copy stamping is an outdated method..if you're gonna teach you should go with the newer for-each based method which is faster.
Thats the beauty of Houdini my friend. Theres a million different ways to do things. In small graphs like this there isn't really a difference in calculation time. You absolutely could do it with a for-each loop but quite honestly there's no reason to do it differently than you prefer. I prefer the copy stamp method. Both ways achieve the same result.
