Physically-based path tracer, developed with Blender but usable standalone.
Why we recommend it
The renderer behind most free product visualisation work — GPU-accelerated, physically accurate, and increasingly used in commercial pipelines rather than just hobby projects.
Strengths
- Physically accurate light transport
- GPU rendering on NVIDIA, AMD and Apple Silicon
- No per-seat or per-frame licensing costs
Drawbacks
- Noise requires denoising or long render times
- Material setup assumes some technical understanding
- Slower than biased renderers for simple scenes
