Issue ID

UUM-18099

Regression

No

Interpolated vector is not normalized resulting in faceted look when using vertex lights

Shadows/Lights

-

Steps to reproduce:

  1. Download and open the repro project ([^BiRP-VertexLights-MixedLighting-Bug01.zip])
  2. Open SampleScene
  3. Inspect Sphere GameObject

Expected result:

  • Indirectly lit faces have a smooth appearance to them

Actual result:

  • Polygons have a faceted look to them (see attached screenshot)

Notes:

  • Reproduces in all public Unity versions
  • Reproduces in Built-in RP only; other render pipelines are unaffected
  • The culprit appears to be a non-normalized interpolated vector between vertex normals
  1. Resolution Note:

    Seeing that this only affects BiRP and we are moving away from vertex light workflows, we are closing this as won't fix.

  2. Resolution Note (2023.1.X):

    Seeing that this only affects BiRP and we are moving away from vertex light workflows, we are closing this as won't fix.
