Custom Fixture editor issue

[viquiuxd]

When I enter to create a "custom fixture" and add a geometry, the object remains black and the "diffuse color" parameters have no effect on the object, what could be the error?

The latest build for me seems to work, I wonder can you share your system specs? specifically your GPU?

Also, when you are experiencing that issue, can you go to tools > errors and diagnostics -> GLSL diagnostics -> refresh? see if any relevant errors pop up. If you're comfortable with TD, you could also dig around in here and see if you can uncover any obvious red or yellow errors: /UberGui/CustomFixtureEditor
