I have a very simple reflective material that is using a cubemap (it is the default reflective/specular material).
However, whenever I have more than 2 objects with this material on-screen, the cubemap vanishes from all but 1 of the objects.
When I delete 5 of those gray blocks, the remaining 2 will properly use the cubemap. But as you can see, when all of these are here, only 1 of them shows the cubemap.
More confusingly, if I take any of the blocks with the broken cubemap and move it far away, its cubemap reappears. What’s going on, and is there a way to fix it?
