When an Atlases 3D model feels too heavy in Godot, it’s usually due to high polygon counts, uncompressed/large textures, or inefficient material setups that strain rendering resources.
- High polygon counts: More vertices force the GPU to process extra data per frame, slowing down rendering. - Uncompressed/large textures: These eat up video memory (VRAM) and delay loading, as the engine struggles with unoptimized file sizes. - Inefficient materials: Complex shaders with multiple passes or unneeded effects (e.g., real-time reflections) add unnecessary overhead to each draw call.
To lighten the model, reduce polygons using decimation tools, compress textures to Basis Universal, and simplify materials by removing redundant features.
