RayTK

v0.41

Restricts which render stages an operator is used in.

This can be used for optimization, by switching off expensive ROPs for shadows. It can also be used to have shapes that are invisible but still cast shadows.

In cases where the main operator is not being included, this will produce either the alternative operator input (if connected), or a default value otherwise. The default value is “non-hit” for SDFs, and 0 / vec4(0) etc for other types.

Parameters

Name	Description	Regular Handling	Read-Only Handling
Enable
Include Primary	Whether the operator should be used in the main raymarching stage where the renderer finds surface hits for rays.	Baked	Baked
Include Shadow	Whether the operator should be used when the renderer is checking for shadows cast on a surface.	Baked	Baked
Include Reflect	Whether the operator should be used when the renderer is determining colors reflected onto surfaces.	Baked	Baked
Include Material	Whether the operator should be used when the renderer is using a material do determine the color of a point on a surface.	Baked	Baked
Include Occlusion	Whether the operator should be used when the renderer is computing ambient occlusion.	Baked	Baked
Include Volumetric	Whether the operator should be used when the renderer is accumulating color within a light volume.	Baked	Baked
Include Volumetric Shadow	Whether the operator should be used when the renderer is checking for shadows within a light volume.	Baked	Baked
Include Normal	Whether the operator should be used when the renderer is calculating surface normals.	Baked	Baked
