I'm on Houdini 18.0.460 Indie and I'm trying out the labs game stuff. I'm in the demo scene for vertex animation textures and the VAT ROP doesn't seem to work. I just get his error:

Error rendering child: /out/soft_unity/render_mesh_fbx

My toolset release is set to 494, but I was also getting this error with 460. I'm using this file specifically: https://github.com/sideeffects/SideFXLabs/blob/Development/hip/vertex_animation_textures_demoscene.hip [github.com]

Any ideas? Thanks!

Are you sure you're using Indie and it's not loading a non-commercial license? That error generally appears when trying to export an fbx with an apprentice license.

Hello mikelyndon-sesi,
Do you mean that Houdini GAME DEVELOPMENT TOOLSET is only available for Indie version ? I'm trying to experiment with VAT but I'm getting a similar error message as Borbs27

I actually have the same issue, this only happens when i export Rigid body tho.
I know this is an old post and sorry for resurrecting this but im going a bit crazy debugging this.
Did you find a fix for this ?

For anyone still experiencing this issue it has to do with the Target Texture size in your Labs Vertex Animation Textures render node. At the bottom under "Settings" check what the last render's textures size was, you've likely got one really long axis.

Increase your textures size to 2048 or 4096 and you should stop seeing this error and be able to render the .exr.
