Ok, it's in the raygen shader: `layout(binding = 1, set = 0, rgba8) uniform image2D image;` And apparently, there's nothing like a `bgra8` for the layout. That is, one would...

Could you please provide some images without and with your proposed changes?

Would it require something more than just requesting that `shaderStorageImageWriteWithoutFormat` feature? If I request that in `request_gpu_features` like so: ``` if (gpu.get_features().shaderStorageImageWriteWithoutFormat) { gpu.get_mutable_requested_features().shaderStorageImageWriteWithoutFormat = VK_TRUE; } else { throw...

... and requesting both, `shaderStorageImageReadWithoutFormat` and `shaderStorageImageWriteWithoutFormat` doesn't resolve that warning either.

@SaschaWillems I think, it's easier, when you craft a PR to resolve that issue using those features?

Regarding all those exceptions: I don't think, it's the right approach to use exceptions for non-exceptional cases. You could instead just use `std::filesystem::exists()` to check if the cached file exists....
