Mobile Vr pipeline-problem with bake light!

Hello i am having problem on baking light, deforms my textures i dont know why,..please help.

 

Do you mean the square-ish discoloration? Those are artifacts from the texture compression. The simplest way to deal with that is to use a diffuse texture with enough detail that it's not noticeable.

Your other option is to uncheck "compress lightmaps" in your Lighting settings. That will use more texture memory, but you can find the lightmap texture in your project and manually try out different texture compression formats. If you have ASTC support, for example, using a block size of 4x4 might improve things (the default ASTC is 6x6, I believe). But if you have texture memory to spare, you may be able to simply keep them uncompressed.
