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 https://beaumondefernhotel.com

WebThe members of a toplevel uniform block are laid out in buffer storage by treating the uniform block as a structure with a base offset of zero. If the member is a structure, the base alignment of the structure is N, where N is the largest base alignment value of any of its members, and rounded up to the base alignment of a vec4.
