Hey Makumba,
You may have answered your own question with regards to the lighting you’re using (static as opposed to stationary/dynamic where if I understand correctly the model renders like you want it to). Here is a post on answerhub in which the user seems to have a similar issue, while not using chrome you can see the major difference in how is material is rendered when using stationary vs static lighting. Static Light doesn't cast reflections - Rendering - Unreal Engine Forums
Another suggestion would be to tone down the skylight intensity if you’re using one in your scene. =)
