Rendering Mental Ray: Common Render Settings
From TOI-Pedia
Raytracing
Activate the raytrace option to use raytrace shadows, reflection and refraction.
- Reflections
- Maximum amount a ray can be reflected.
- Refractions
- Maximum amount a ray can be refracted. If the value is to low, black spots can appear.
- Max Trace Depth
- Maximum amount a ray can be reflected and refracted. The total amount is similar to the combined value of the previous two settings or can be lower.
- Shadow Trace Depth
- Maximum amount a shadow ray can be cast for shadow calculations. This is especially important if shadows have to be visible in a reflective object.
The amount of reflections and refractions has a strong impact on the time to render an image Especially objects with a lot of overlapping transparent materials can be memory intensive to render.
