Rhino Shadow Study Hack | Rhino + V-ray

- **For Rhino 6 and V-Ray Next users experiencing errors**
It seems that the new version of V-Ray and Rhino have different ways to do this. I had to enable 'Animation' and 'Save Image' under 'Render Output' in V-Ray settings and turned Rhino document sun 'on'. Then I used the regular 'Render' command instead of 'RecordAnimation.'
Today's hack is about streamlining a shadow study for a hypothetical tower in New York. A streamlined process allows designers to leverage the power of their computers to speed up the process of production. We'll be using Rhino and Vray to streamline the production process so that computer works while you can sit back and relax!
A shadow study (sun study) is a common procedure in the architectural design process. However, it can be tedious and time-consuming. They are often in need of updates as massing evolves.

Is there a problem with the new vray next? when starting the recording of the animation, it interrupts already after the first pass... please wait for the current render to finish. the result i get in the end is just one frame with no shadows or lighting. it seems as if rhino doesnt animate the onedaysunanimation (rhino 6)
can you help me?
ok, i just changed the capture method to raytraced or rendered viewport and it worked..
but still i dont seem to get the same result with sharp shadows or the shadow channel
Hi Hans , it seems that new version of V-Ray and Rhino have different ways to do this. I had to enable 'Animation' and 'Save Image' under 'Render Output' in V-Ray settings and turned Rhino document sun 'on'. Then I used regular 'Render' command instead of 'RecordAnimation.' Let me know if that works for you!
@@ArchiHacks oh wow thanks a lot, that works just fine for me!
mine does not say render elements and i cant add shadow so it doesnt become inversed what can i do??????//
Hi Noah, I can take a look. Could you send me a screenshot via other sns? Thanks!
Hi, may I know why I can't do record animation with a specified view I created? There says "unable to find viewport to play animation".
Thanks!!
Might be a result of having a newer version of Rhino and v-ray! Have you tried solutions given on other comments on this video?
@@ArchiHacks got same problem here, tried to enable the animationa and save image in v-ray setting but only gives one image render with no shadows.
I don´t know if it is of any help to this point, but I had the same problem and instead of typing in the command, is just went directly to "Render Tools" tab and clicked record animation from there and it worked.
i don't know why but when i run the "record animation" it doesn't save the shadows and alpha in the animation folder // the rgb saves
i have tried the solutions you recommended down in the comments but it still doesn't work
can you please elaborate on how to get all the rendered images saved in the folder automatically?
Hey yusra, does it create blank files or no files at all? If you've already tried everything, I can take a look via google hangout : )
Hi @@ArchiHacks,
Just the "RGB color" layer saves
but its okay now I figured out a way;
The frame buffer automatically pops up when one shadow layer is done and I save it before it starts rendering the other shadow layer.
It was getting frustrating hence I asked; thanks for your reply; appreciate it :]
@@yusra7 I'm glad you found a work around. I have not thought of that one before! I found that newer version of V-Ray allows you to do something similar. I'll see if I can figure it out and make a followup video!
Saikou! Thanks for sharing
Awesome and quick way to do a shadow study the only problem is I dont have the same V-Ray settings as you do, I am missing Raytrace, Caustics, Render Elements and Switches do you know why? also Summer solstice is 21 of June my birthday!
Hey Shakti, V-Ray has changed their interface quite a bit since the making of this video unfortunately! If you have the latest version of V-Ray, check the tab amongst materials, objects, settings to find render elements. You might have to refer to other comments to find workarounds for other steps too. Anyhow, that's an incredible coincidence! Happy early birthday haha
Hi Thanks for the tutorial! Any Idea why the shadow and alpha channels are not exporting to file?
My pleasure! Perhaps your save button is not set to save all channels. Long click on the save button and choose 'save all image channels to separate files' in V-ray frame buffer window!
Great vid but how were you able to render out the RGB and Shadow channels into separate files?
Hi Sean, it should save automatically if you have the channels included in your render elements in the V-Ray asset editor. Let me know if the problem persists!
Hey @@cal5742, thanks for bringing this up. I tried running the steps and I found that this method is no longer working. I'll see if I can find a workaround and get back to you!

My renders are being saved all white, why?
Make sure you enabled render elements, and have the right level of exposure on camera or VFB! Let me know if that doesn't work : )
