VK_IMAGE_USAGE_STORAGE_BIT usage flag (check if the format suports that first) Create and assign a descriptor of type VK_DESCRIPTOR_TYPE_STORAGE_IMAGE for that image for the compute pass The reason for this seems to be that vulkan (for some reason, I still don’t really know why) only returns the result of the compute shader to the descriptor, which means it only fills memory for the first image (since the descriptors bind the memory) A compute shader can only read from or write to resources defined by descriptors Using compute shaders, you can do something like this (separating the filter or not): For each work group, divide the sampling of the source image across the work group size and store the results to group shared memory This change was driven by the external dependency on SPIRV-Tools Intersection Shaders com/AregevDev/eaf841fb469fd13ce4343b Hope I … By doing this, we are letting vulkan know that we want our compute shader to be executed in groups of 256 elements at a
