Remarks

This ensures that any asynchronously compiled shader permutations are completed before rendering the frame. When using On Demand Shader Compilation the editor will skip compiling currently unneeded permutations for the material graph to decrease artist iteration time, but these permutations need to be compiled when rendering. Results are stored in the DDC on subsequent uses.
