If the draw call before a DrawMeshInstanced call has a negative scale, the normals on the instanced call will be flipped

Graphics - General



Priority: 7Not yet prioritized for a release


Severity: 3Workaround is possible

Reproduction steps:
1. Open project attached (Repro
2. Disable "Sphere (1)".

Expected result: Floating cubes will remain the same.
Actual result: Normals are flipped on floating cubes.

Notes: This happens when there is an object with Negative scale and it is the last object drawn in the scene. If there is an another object further, then normals remain the same.
I edited material since the old one had some mistakes in the shader.

Reproduced on: 5.5.1f1, 2017.1.0p5, 2017.2.0b9, 2017.3.0a6.
