Hey wondering if anyone can help… I’m working on a landscape material and moving from using an atlased to a non-atlased material and basically getting some weird effects…
In brief, moving from using a 4x4 texture atlas material as it was really reducing fps. So have made an equivalent landscape material that doesn’t use an atlas and instead uses “shared: wrap” texture samplers with roughness and height baked into the alphas of the diffuse and normal textures to get the same 16 available landscape layers (see attach).
Below are videos of the two materials applied to the same map:
Video of atlased material: Land Atlas - YouTube
Video of non-atlased material: Land NoAtlas - YouTube
Comparison shot: LandMat7 — Postimages
As can see from the video in the non-atlased material the landscape becomes lighter and desaturated as it moves away from the camera, all of the colours are also generally a lot darker … Both materials are using exactly the same source textures, the landscape material settings are exactly the same, and both use height blending. The materials were both applied to the same level so all lighting and post-processing settings are the same. I thought it might be something to do with the mipmaps but doesn’t seem to be the case. The texture import format is 8-bit RGB targa…
Any ideas if you’ve seen something like this before would be awesome…
