Surface¶
- Displacement
Method used to perform Displacement on materials.
- Displacement Only:
Mesh vertices will be displaced before rendering, modifying the actual mesh. This gives the best quality results, if the mesh is finely subdivided. As a result, this method is also the most memory intensive.
- Bump Only:
When executing the surface shader, a modified surface normal is used instead of the true normal. This is a less memory intensive alternative to actual displacement, but only an approximation. Surface silhouettes will not be accurate and there will be no self-shadowing of the displacement.
- Displacement and Bump:
Both methods can be combined, to do displacement on a coarser mesh, and use bump mapping for the final detail.
- Emission Sampling
The method used for sampling the emissive component of the material. This option will only have an influence if the material contains an emissive material node, otherwise it will be ignored.
- 없음(None):
Do not use this surface as a light for sampling.
- Auto:
Automatically determine if the surface should be treated as a light for sampling based on emission intensity.
- 앞:
Treat only the front side of the surface as a light, useful for closed meshes whose interior is not visible.
- 뒤:
Treat only the back side of the surface as a light for sampling.
- Front and Back:
Treat surface as a light for sampling, emitting from both the front and back side.
- Transparent Shadows
Use transparent shadows if it contains a Transparent BSDF, disabling will render faster but will not give accurate shadows.
- Bump Map Correction
Applies corrections to solve shadow terminator artifacts caused by bump mapping.
Volume¶
- Sampling Method
- Distance:
For dense volumes lit from far away Distance sampling is usually more efficient.
- Equiangular:
If you have got a light inside or near the volume then equiangular sampling is better.
- Multiple Importance:
If you have a combination of both, then the multiple importance sampling will be better.
- Interpolation
Interpolation method to use for the volume objects and smoke simulation grids.
- Linear:
Simple interpolation which gives good results for thin volumes.
- Cubic:
Smoothed high-quality interpolation needed for more dense volumes, but slower.
- Homogeneous
Assume volume has the same density everywhere (not using any textures), for faster rendering. For example absorption in a glass object would typically not have any textures, and so the renderer can be set to avoid taking small steps to sample the volume shader. Usually this is automatically determined by the renderer. This setting provides a manual control for cases where it is not detected.
- Step Rate
Adjust distance between volume shader samples for volume shaders. This is typically used to reduce the step size for procedural shaders that add more detail with procedural textures, when it is not captured by the default step size. See Volume Render Settings for more information.
