Hi,
it could be an issue with materials conversion.
About materials and .orbx export, please follow these steps:
- Open the scene in c4d, select all materials, then go to Live View menu Materials/Convert Materials, then Remove unused Materials commands, to remove any C4D material in the scene.
- Then go to Live View menu Materials/OctaneTexture Manager, and check that there are no missing texture files in the scene.
- Please also check that all the textures are listed as ImageTexture, not Bitmap.
Please, always use an ImageTexture node before loading any kind of image into c4doctane:
https://docs.otoy.com/cinema4d/ImageTexture.htmlOctane is a Spectral render engine, so every texture must to be converted to the proper color space before been used.
This is even more important for Lighting, and in particular for Emissive materials or Environment node.
- Please also check that there are not c4d Shaders in your scene, unless they are C4D Noise or Gradient nodes.
Most of the c4d native shaders are baked on the fly, but this automatic option slows down the process (especially in complex scenes) because the textures are rendered and updated at every interaction, plus, not all the shader are completely supported. In particular, the Layer shader is not support and you can have incorrect results, and instability. But most important, c4d Shaders cannot be supported in Standalone/RNDR.
From RC3 there is a new option for auto converting c4d shaders into OSL Octane nodes, that is far more stable and productive.
Currently it works for C4D the Noise and Gradient nodes:
So only keep the OSL option active, and disable the auto baking option.
