@ -103,10 +103,21 @@ add: Cinematic Rendering Pipeline CVars
0 - disabled
1 - 1/4 pixel count, 9 samples total
2 - 1/16 pixel count, 25 samples total
motion blur:
crp_mblur <0 to 3> (default: 0) sets the motion blur mode
0 - disabled
1 - camera blur only
2 - object blur only
3 - camera and object blur
crp_mblur_exposure <0.0 to 1.0> (default: 0.5) is the exposure time in percentage of frame time
miscellaneous:
crp_drawNormals <0|1> (default: 0) draws vertex normals as colorized wireframe lines
crp_updateRTAS <0|1> (default: 1) enables raytracing acceleration structure builds every frame
add: Cinematic Rendering Pipeline commands
cin_freezeFrame freezes the rendered frame (minus ImGUI and tone map) and G-Buffer for inspection
cin_freezeFrameMB freezes the rendered frame (minus ImGUI, tone map and motion blur)
fix: allocating enough memory for 4K screenshots and video captures
fix: the new demo player now drops zombie snapshots and snapshots from before a server time rewind
