Win10, Intel Core i-5, NVIDIA GTX1060, Unity 5.4.2p1, OpenVR(Vive), forward rendering mode.
I set atlas size to 4096, and result lightmap is indeed 4096(confirmed), but the default max resolution for texture is 2048, so the lightmap .exr files are imported as 2048. I can change the “light lightmap” to 4096 and it’s fine since it’s sRGB format, but I can not change the “direction lightmap” because as soon as it’s reimported, its format change from Linear RGBA to sRGB, and things look incorrect.
So I guess one way possibly to fix it might be that change editor setting of default max resolution of texture to 4096, then generated 4096 lightmaps are good to use by default, anyone knows how to do that? Or is there another way around? Thanks.
