Quick question : is there a limit on the number of image textures Cycles can handle ? I’m trying to render a script-generated scene of 20,000 objects all with unique materials and image textures. However it seems that only the first 1,000 imported objects render correctly. The rest show up as uniform pink. If I move a pink object to another layer and render only that layer, it renders correctly. Similarly if I import it to another .blend it renders fine. I searched for this issue but could only find some very old references, mostly about the GPU but I am using the CPU.
I suppose I could get around this with alpha-over composition but it would not be straightforward as I’m planning to have the camera move around quite a bit. Although the scene’s got a lot of materials and objects it renders very fast since the materials are just shadeless and transparent, so apart from this one show-stopper it’s working well. Unfortunately I can’t use the BI engine as I want to render spherical stereo for a VR headset.
