jamie hayes 257ae60ff4 New material option: "Always Evaluate World Position Offset". This new option is used to force World Position Offset to always be evaluated for a material so that it cannot be disabled by the likes of "Evaluate World Position Offset" or "World Position Offset Disable Distance" on the component. This is useful for meshes that use WPO for behavior like billboarding (i.e. imposters) where WPO shouldn't be disabled for performance. ...

This option has the following knock-on effects of other rendering systems to prevent potential bugs or artifacts:
* For non-Nanite meshes, enabling this option will force instances of draw commands with this material applied to always invalidate VSM page cache when instance culling for VSM shadows.
* For Nanite meshes, enabling this option will force all clusters of all instances to pad cluster culling bounds and invalidate cached VSM pages, even if clusters don't have this material applied to it, as it would be prohibitively expensive to determine if no materials on the cluster would force invalidation.

NaniteDefinitions.h

Improved (and correct) implementation of Nanite fast tile clear optimization. This new version fixes issues where even fully Nanite shaded tiles would not write through all/any of the gbuffer, but we would still unset the metadata (resulting in uncleared gbuffer / hall of mirrors). New implementation builds a per material bound target mask (based on shader reflection), masks that against possible bound targets suitable for the optimization, and then the clear shader determines which tiles are safe to optimize the meta data, and the rest are cleared by the regular hardware path.
