EyeonTips:Manual/Fusion 6/Catcher

From VFXPedia

• How to render soft shadows using the SW-renderer and depth of field using the OGL-renderer? An example comp by Eric Westphal can be found in this pigsfly thread.

• The Blend accumulation mode (available since Fusion 6.1) will perform an additive merge of multiple projectors. For this to work you need to define a projector priority for each Projector3D or Camera3D. Higher priorities are considered on top of projections that have lower priorities. These foreground projections should have an alpha channel with transparent parts where the background projections will show through.

• The OpenGL renderer currently doesn't support all the accumulation modes. For "Blend" mode, you need the software renderer. However, you can merge multiple catcher materials (using different projector IDs) using the Material Merge. This will work in OpenGL (example comp)

• When using the software renderer, the catcher tool will fill pixels outside of the projector's frustum with the canvas color of the image that is being projected.
