I have a UE5 bug I need to work around before being able to release 1.3 but hopefully I can get back to 1.4 development soon. Thanks for the offer, but it should be fine.
There are quite a few clues in the UE5 source code to suggest nanite support for masks, double sided geometry, pixel depth offset and world position offset are on the cards in a future release (nanite programmable raster)…
