#3963

mafiesto4 61b6aeb252 Fix missing DDGI on D3D11 when object counter readback buffer doesn't have data on time 
(eg. during very fast rendering)

mafiesto4 cf3bcc4549 Fix DDGI flickering on floors aligned to world axes 
Apply a small bias to sample location and dither it a bit to smooth out.
 2026-01-05 17:19:16 +01:00
mafiesto4 11ea889fa9 Refactor DDGI fallback radiance to use alpha for blending between fixed color and color at snapped location of the last cascade 
This means artists don't need to adjust the value anymore as it can cover vista geometry with GI at last cascade borders.
 2026-01-05 16:22:00 +01:00
mafiesto4 c5a28a5734 Refactor DDGI irradiance sampling when nearby probe is missing to use precomputed fallback probes 
Also, insert fallback/dummy probes when there is no SDF nearby to have lighting in all cases.
This both improves sampling performance and fixes issues when sampling in areas far away from valid GI.

mafiesto4 03898a064a Optimize DDGI probes border pixels to be copied within probe update, rather than via separate dispatch 2024-07-18 19:51:01 +02:00
mafiesto4 aeff147b6d Optimize and refactor DDGI to use linear attention per-probe to dynamically control ray count and blend speed 
Probes will use lower ray count when behind the camera or not correlated with the view direction or far from geometry.
Probes nearby camera or with high instability in irradiance will maintain higher ray count.
Probes that use less rays will have slower blending to reduce artifacts.
Added probe instability, attention and stats debugging for devs.
