Merge pull request #3574 from aws-lumberyard-dev/Atom/santorac/MoreShaderHotReloadFixes
Fixed a shader hot reload issue where the new root shader variant asset was not getting saved in the Shader object during OnAssetReloaded, it was only saved during OnAssetReady.
Fixed shader variant hot reload which was failing due to mismatched timestamps. The ShaderAsset was using microseconds and the ShaderVariantAsset was using system ticks. Since ticks will always be higher than microseconds, stale variants were not prevented from being used.
AtomSampleViewer's MaterialHotReloadTest script is passing again.
