The issue was caused by the conflict between preview render which would set R_NO_IMAGE_LOAD flag on the renderer and texture samplers called outside of the render pipeline trying to use this flag. Now the sampler functions accepts extra argument so render pipeline can still skip image load, but calls outside of the pipeline will nicely load all the images. Not cleanest change in the world but good enough to unlock gooseberry team, and assuming we already had pool passed all over the place it should be all fine. Will need to reshuffle arguments into SamplerOptions structure later.
