[PathTracer] AddInstanceProperties errors are thrown when baking progressive lightmapper

Global Illumination



Priority: 2Necessary for shipping a final release


Severity: 3Workaround is possible

To reproduce:
1.Open Unity project attached by QA
2. Open Example scene if not opened
3. In lightning window press "Generate lightning"
4. In console window notice a lot of errors : [PathTracer] AddInstanceProperties...

Excepted result: Baking is done successfully.
Actual result : A lot of errors.

Reproduced with: 5.6.0p3, 2017.1.0b3
Not reproducible with 5.6.0b9
Regression introduced in 5.6.0b10
In earlier versions progressive lightmapper is not available.

Was not able to test on 5.6.0f3 because of errors.

Note: In hierarchy window deleting game object FireComplex (World->Props->Barrels->BarrelDestroyedRed) fixes this issue.
