Stuck trying to figure out the shading problems of this model

I’m working on a showrrom scene and I have this TV cabinet that has weird shadows on the drawers. I don’t see a problem with the model or the UVs and I set the lightmap resolution to 1024 and the shading is still iffy. The rest of the scene is shaded well for the most part.
What other things should i look for?
I render at Production quality with the default lightmass settings.



You need to change lightmass settings. And I think there must be many more lights around this tv cabinet…

i have one light per showroom space so it’s lit with the main ceiling light and the bounced lights from other assets (as shown). is there a base lightmass settings i should start with?
