UE4 on Qualcomm® Snapdragon™ 805 with Adreno™ 420 GPU

Re: Android - LogTexture:Error: Texture2D is unknown which is not supported - Rendering - Unreal Engine Forums

I’m running into a texture sprite issue on the Qualcomm® Snapdragon™ 805 with Adreno™ 420 GPU.

The sprite displays correctly on a the OUYA / Tegra 3.

I’m trying to dig down to why this might be happening.

The Snapdragon should be 2-3 times faster than the Tegra 3 or near equivalent to a Tegra 4.

I created an isolated project to reproduce the issue.

I’ll start by comparing the logcat.

Here’s something from the logcat on the OUYA.

D/UE4 ( 7269): [2015.08.26-17.02.59:703] 0]LogRHI:Warning: Texture TextureSprite (Index 0, Resource 51) has a non-clamp mode; switching to clamp to avoid driver problems

I’ll try doing that and see what happens…

The core issue ended up being the texture Compression Settings.

I changed the Compression Settings to “UserInterface2D (RGBA)” and now it displays on the Forge TV.
