UPR 12: terrain shader does not support shadows masks in deferred

the deferred pass just misses the pragmas but includes some older ones?

this is from:

Hi @larsbertram1 ,

Could you please submit a bug report for this issue, ideally with a minimal reproduction project?

hi leonhard,

thanks for coming back to me. unfotunately it turns out that shadowmasks in beta 5 are broken in forward and deferred.
and not only on the terrain but also when it comes to the lit shader. although the lit shader looks a bit better.

  • terrain does not pick up the shadowmask at all but goes fully black
  • lit does - at least right after the transition from real time to shadowmasks
  • both drop shadows completely at a certain distance.
  • this happens in forward and deferred in beta 5 now

Thanks a lot for the report and for bringing this up! We’re looking into it.

Using Linux. Works fine on OpenGL Core, but on Vulkan it has the same issue.
