Getting a weird gradient glitchy look on iOS....

Update: I created a cube in Unity, and drag and used an image file to texture it - Letting Unity create the material, while my other models are using materials from 3DS $$anonymous$$ax. It's hard to tell for sure, but this material seems to work better - I'm not sure. It's hard to tell. I'll try to find a better material.

So maybe it's a problem with the import process? There aren't any settings to be had in importing a material without a texture though, and the materials that do have a texture, are set to 2048 size, Truecolor.

I'm not sure about iOS, but I know for Android that if you use texture compression, you'll get color banding as you mention. Setting the texture to truecolor should fix that, the downside is the filesize is much larger. I haven't experimented much with reflections, so I'm unable to comment on that. Increase depth buffer?

Update: It seems it's not caused by 3DS max materials after all, but rather setting tilling high (In my case: 15 x and y) And when the object doesn't have quite as much reflection, it looks more like what is shown in this thread: http://forum.unity3d.com/threads/weird-artifact-on-overlapping-tiled-uv.204083/

Compression is disabled in world reflections, as well as all textures (Also everything set to true colours), but this also happens on materials with no textures!

Update: Another test with tiling set to 1. It's definitely less noticable, but the problem still persists. Using the standard skybox, and the standard material; when looking at the reflection, grainy noise appears around the horizon line. I'll try turning down metallic, as it is currently set to 1.

Update: Turning down metallic didn't (as expected) help much, but turning up smoothness did. Why would making it less blurry help?! So that makes it look better, but that's like putting a bandage on a flesh wound. Not a solution :/
