Add VK_ACCESS_COLOR_ATTACHMENT_WRITE_BIT to colorDependency.srcAccessMask and depthDependency.dstAccessMask Add VK_PIPELINE_STAGE_COLOR_ATTACHMENT_OUTPUT_BIT to depthDependency.srcStageMask and depthDependency.dstStageMask
Added a per‑TransferTask fence to serialize transfer submissions so back‑to‑back vkCmdCopyBuffer writes can't overlap on the same queue.

I've done a first pass review and feel that issues need to be investigated fully, while these changes may be a solution for quieten the validation warnings, there might be more appropriate ways to tackle them. Could you submit the access mask changes and the fence addition as two separate PRs. When I get to testing and investigating whether these changes are appropriate I'll need to do performance testing as well as checking validation, and testing against other examples as making changes that affect all a broad usage case might have unintended consequences on performance and behavior. |
