Unreal lighting results in strange dark shadows

SketchUp's Real-Time Rendering Moment: Lumion View, AI Render, and the End of the Export Workflow

SketchUp 2025–2026 has added native PBR materials, AI image generation, and real-time rendering plugins like Lumion View, letting archviz artists produce photorealistic images without leaving the viewport. This collapses the traditional design-to-render pipeline.

Unreal lighting results in strange dark shadows

I'm trying to understand why I'm getting splotchy, dark shadows on meshes when I build lighting. I used the the global lightmass settings that were in the purchased project and that helped a bit but did not completely fix the problem. To test the issue I created a simple scene with an evermotion mesh, a plane and a directional light which you can see attached. Rotating the light can also help with the shadows but never removes them completely. This is not limited to the sofa mesh pictured but is happening on all the assets. 192613
