Thanks Chris, I tested switching alternatively the two materials (with and without full precision) but I can’t see a significant improvement. Is it possible that the texture resolution gets clipped to 2048x2048 on android?
Also, the video exhibits a lot of aliasing, even though I have enabled MSAA 4x (not sure if this is supposed to work also with textures or just with edges, though).
Is there anything else I can try?
