This requires full precision floats in a pixel shader, and 4.13 has an option for that.
Using ScreensAlignedUVs material node on some devices does not render correctly at farther distances.
Devices tested with:
Working: iOS 5s and Pro
Working: S7 Edge - SM-g935P
Working: LG G4S - LG-H735
Not Working: Samsung Galaxy S5 - SM-G900P
Not Working: Nexus 5
Not Working: LG G2 - LG-D802
Not Working: Samsung Galaxy Tab 4 - SM-T530
Not Working: Samsung S4 Mini
1. Create a Mobile Project
2. Create a Material using the ScreenAlignedUV node plugged into a Texture Sample plugged into the Emissive Material input.
3. Make the material Two-Sided
4. Add a Sphere to the default level and scale it really large
5. Deploy to device
6. Pull back the camera until you see the issue (screenshot below)
Regression: No
Results: Looks like a distance precision issue for some devices when using the screen aligned uv node.
