After playing around with the really handy merge actors feature in UE4, I figured that another great feature would be an automatic atlas map generator, where all the textures used (of the same kind, albedo +albedo, normal + normal, etc) were all combined into a single texture sheet with options for resolution. I feel this would be a pretty simple feature to implement, but could save quite a bit of performance to be able to combine textures in the editor itself.
Paper2D does that.
Does that work for all types of textures?
Nope; it only make some sheets for its sprites I think.
But I’m not sure if it really generates Atlases, maybe not. I’ve seen a twitch stream a long time ago, I assume it generates sprite sheets, but not for any kind of texture.
This would make Texture streaming very inefficient.
