Starting at Haswell, the hardware supports texture swizzle directly and we rely on that for Vulkan. As I said above, it would be possible to implement with shader code but it's quite a bit of work and significantly harder than what we do in OpenGL.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
