Description
When both Batch Meshes
and Precompute Tangents
options are enabled, strange artefacts appear on the rendered mesh.
For example, consider a 2 X 2 arrangement of 4 identical grid mesh objects:
The meshes share the following material setup:
Either/ both options disabled | Both options enabled |
---|---|
Correct: | Incorrect: |
Also, this issue does not happen if all the objects share the same mesh data (like linked duplicates).
