offset parameter of attribute noise creating bad shading. March 17, 2024, 4:27 p.m.
that large of an offset causes the noise space to run out of numbers due to catastrophic loss of precision. 32 bits only gives about 6 or 7 decimal places of precision, so adding a 7 digit number leaves you with 0 decimal places to work with.
Convert vertex color from linear on import to sRGB on export March 17, 2024, 1:02 p.m.

Hello Tomas (or anyone else),
Your help did the trick for all the parts I had to convert that had vertex color. I assume it's possible to do the same thing for parts with textures instead -- but I'm not seeing how. Do you have suggestions? I tried hooking up texture attributes instead of Cd in the VOP you suggested, but clearly I'm either doing this wrong or it's not the right approach, because the color of the textures isn't being converted.
Thanks so much,
Mary
In what context are we asking about? I'm not aware of any where texture conversion take place. The bake texture nodes I think can convert to an srgb color space when the target format requires it, but I don't know if they are ocio aware. The other exporter tools that include textures like gltf or fbx or usdz do a simple file copy without conversion afaik.
