pretty straight forward.
connect to both gizmos:
- shadow casting geo
- shadow receiving geo
the shadow 3D gizmo will give you a shadow pass for multiplying or grading the image. following knobs exist on this gizmo:
- Light Type: You can choose the light type. Parallel/direct or point/spotlight.
- Shadow Quality: The shadow quality is essentially the focal
length of the shadow projection camera. higher values give smoother
results. but too high values cuts the edges of shadows. really low
numbers are needed especially when set to orthogonal (down to 0.2).
- Scanline Samples: adjusts the scanline renderer that renders the shadow pass
- finally you can choose disable to get the full shadow with the parts that get occluded by the shadow casting object himself
the RenderBoth gizmo needs the same inputs and simply renders both
geometries for multiplying (or getting graded) with the shadow pass.
additional settings of the used scanline renderers will be implemented.
dunno if this could be of any use for someone else.
