WebMar 1, 2014 · I Think your problem don't come from the offset format but from the texture coordinate format. OpenGL documentation : gvec textureOffset(gsampler sampler , vec texCoord , ivec offset [, float bias ]); . The texCoord will have its value offset by offset texels before performing the lookup. Cubemap, multisample, and buffer samplers are not … WebFeb 22, 2024 · 1 Answer. Push constants live in a single chunk of contiguous memory. The compiler doesn't try to append multiple blocks into that memory; like with the GLSL syntax, it's intended to just have one block containing all the push constant data. This is consistent with other places where the compiler has to pack variables in a block: it only packs ... how to remove onedrive link in file explorer
