When a camera 3D model runs slowly, it’s usually due to high polygon counts, unoptimized textures, or hardware that can’t handle its complexity (like a weak GPU/CPU).
- **High polygons**: More details mean your system must render extra shapes, slowing performance. - **Unoptimized textures**: Large, uncompressed images use more memory and force hardware to work harder. - **Insufficient hardware**: If your device lacks power, it struggles to process the model smoothly.
To fix it, try reducing polygons (with tools like Blender’s decimation) or compressing textures—simple steps that boost speed without major detail loss.
