Unitl recently, I've been able to use these shaders on all platforms without problem:
Bumped Diffuse Bumped Specular Transparent/Bumped Specular Reflective/Bumped Specular
These still work on all platforms except Android. I have no idea what changed that would cause it to crash.
In the case of Bumped Specular, I actually do have several objects that use it, but when I enable others (which are just some boxes), it crashes.
I can have maybe one transparent/bumped specular in scene, but more than that and it crashes. In this case, not right away, but when I start moving around. I think it may be when two or more such objects begin to overlap.
Reflective/Bumped Specular just crashes. Pity, it looked really great too.
Any ideas on why this might be happening? Is there a particular size or compression or some other setting I should be paying attention to? (my sizes are all pretty reasonably small).
