Tricky that GrassMaps_SampleWorldPos in PCG HLSL have rotation offset if landscape have rotation offset e.g. -90 degrees. My farmfield crops dont appear in right places.
Tryed to use GrassMaps_Sample, but it dosent seem to return any data. Are the texturecoordinates 0 to 1 or something else?
EDIT: Maybe getting it working by counting grid cell center from bounds and using it for position after GrassMaps_SampleWorldPos. Could rotate all points around that center.
