Shadow Mask

Owned by Former user (Deleted)


Node Location: Material

Description

This node will detect the areas of shadow in an input colour map and generate a mask to aid in the removal of it, or to facilitate the adjustment of these areas. 

It can be supplemented with the addition of a scanned height map for added accuracy, although there is a known issue with height maps not always generating an improved mask.

Parameters

Inputs: 
    • Color Bitmap:
      Node accepts single bitmaps
    • Height Map:
      A baked height map sourced from scans can add accuracy to result

  • Properties:
    • Threshold:
      This slider will adjust the generated mask. Larger values will encompass wider areas of shadow
