A model export does not include the materials - it’s an export of just geometry.
However, a recent PR may change that :wink: feature: add option for including shaders on model export. #69

The material turning green I believe is a viewport refresh bug because we ‘briefly’ disconnect the shaders in the scene to ensure certain exports are clean in a way we need. (Unless you’re getting actual errors?)

You may try to run mel command ogs -reset to see if that ‘clears’ the green preview… if so, then it’s definitely a maya viewport refresh bug. If it doesn’t - then we should identify what breaks.
