Currently evaluating UE4 for use with developing our next mobile game…
One thing that is a huge hassle with Unity is getting properly compressed PVRTC textures. Unity uses a very bad compressor that makes any textures with alpha look quite ugly. Instead, we’re forced to hack in a third party solution, but it’s a very obnoxious extra step.
See the links below for a good explanation of the issue.
Not all PVRTC are created equal | Toxic Blob (it’s better in this version but still not great)
Will UE4 be solving this problem on a permanent basis? I understand that lossy compression has no perfect solution, but just something that didn’t have so many artifacts that it wasnt fairly useless for RGBA textures.
