OTOY Forums

I've seen some folks use vertex maps in Octane - but I'm having some issues rendering a texture driven by an animated octane map... not sure if it's fully supported. Read that it is in v3.

Does ayone know if animated vertex maps are supportd and can be used in conjuction with textures / mix materials.

Would be helpful if you share a sample scene while ask somethings. There maybe overlooks or limitations on appproachs of implementations.

I've got a plane that's deforming and a vertex map is generated based on height of the deformation.

I want to use the generated vertex map as the Amount texture in an Octane Mix tag to mask tow materials.
Is it possible?

Seems to work with animation in the IPR but when endering to picture viewer it looks like the vertex animation isn't updating.

I added force update to picture viewer object tag, also tried update all geo in settings but doesn't seem to update when rendering to picture viewer. Do i need to keyframe something to trick it?

I went back to 'Resend only updated objects' but enabled the All objects movable.
I also turned motion blur on ...

One of those seems to have solved it, it think. Getting a few dropped frames tho.

Would be great if you share a scene to see if there's a need for fixing somethings.

Hi akotar

Thanks for following up.

I was using Hot4D to generate vertex maps for ocean foam... it's probably something to do with how the maps are generated by that plugin and not Octane/my settings.

*When I put the vertex effect node into an octane 'add' shader in the mix material amount field, it also seemed to update the maps in render view. I'm convinced it was my setup that caused it not to update and not an octane plugin issue.

The scene file has changed but If I get a chance i'll try replicate the issue and repost.

Cheers

Hello!
I stumbled across a similar issue, while working with fields.
Creating animation via fields and VertexColorMap tag - works, while creating the same animation using Vertexmap tag - doesn't. Well it kinda works, for octane gets an updated animation frame each time I hit render, so I added an octane tag with "force update" enabled, but still - no animation on render.

Files attached.

It will work if you this. Only last tag is counted by plugin. Limit is one vertexmap/color tag for one object. I'll look to extend it as 4 vertexmaps+2 colormaps

Yaaaay! it works! Thanks!

Hi,

I've got kind of same problem with my scene.
I try to understand what was your answer Aoktar, but can't figure out.

Could you help me ?

Here is my scene.
