WebMay 23, 2024 · Oh, okay. Well the only significant difference between say 2D array texture and a 3D texture in terms of data is the way the mip-chain is allocated. An 8-slice 3D texture has 8 slices in the Z direction for the first LOD, 4 for the second, 2 for the third and 1 for the fourth. You only have 1 mipmap in this texture so that does not much matter. WebJun 12, 2024 · No, cubemaps sample only 1 of the 6 textures in 2D. The textures can internally have a 1 pixel border that reproduces the pixels for the neighbouring texture on the cube, giving the impression that it's sampling from multiple faces but it is only sampling a single 2D texture.
