Parameter Details Preview In Viewport Preview the generated image as an overlay in the viewport.
- Off : No preview is generated.
- RGBA : Preview the image blended with alpha in the viewport.
- RGB : Preview the colour channels in the viewport.
- Alpha : Preview the alpha channel in the viewport.
- PIP : Preview the image blended with alpha in the viewport, in a smaller picture in picture display, on top of the existing content.
Apply PostFX Before Alpha Image Input (Legacy) When enabled, the alpha input image is applied after the postfx pass, overwriting any effects the postfx would have applied to the alpha channel.
Depth Scale Control the scale of the depth in the normal map.
Invert Normal X Invert the direction for the normals generated along the X axis. This will affect the direction lighting appears to come from on the surface.
Invert Normal Y Invert the direction for the normals generated along the Y axis. This will affect the direction lighting appears to come from on the surface.
Invert Normal Z Invert the direction for the normals generated along the Z axis. This will affect the direction lighting appears to come from on the surface.
