Broken Cubemap in 4.2
I'm having an issue with a cubemap which results in what looks like bad texture coordinates.
The problem only appears when I deploy to my phone and only started happening when I moved to 4.2 from 4.1, on 4.1 everything was fine.
On 4.2 the cubemap appears perfectly fine in the editor as well as mobile preview, it just becomes distorted when on the phone.
I wondered if there's any suggestions out there on how to fix this issue?
Here's my material:
I would guess it's due to low precision in the pixel shader on device. Phones use half precision for pixel shader operations, like anything plugged into Emissive or BaseColor. Vertex shaders will usually use full precision, which is inputs like WorldPositionOffset, CustomizedUV. Try using Customized UVs to pass through your computed UV, and then only do the texture lookup in the EmissiveColor chain.
