When a 3D model’s lights cause rendering crashes, common issues include overly complex setups, render engine incompatibilities, or insufficient system resources.
- **Overly complex lights**: Too many dynamic/high-quality area lights overload the engine. Unoptimized volumetric lights (unsupported by the engine) also trigger errors. - **Insufficient resources**: Lack of RAM or GPU memory can’t process light data during rendering.
To fix, simplify setups (e.g., replace multiple small lights with one area light) or update the render engine—this resolves most issues without heavy system changes.
