VRay Dirt Radius Setup

[varx3d]

Hello all,

Vlado, I have to ask one question regarding VRay Dirt radius, like the setup with the Refl.Glossiness thread, which can be emulated 1:1 with 3dsmax using a blend node in Maya.

1.What setup is needed or how I control the Radius once I plug in a blender node to achieve the setup as the bottom part of the image on the left?
2.Exclude section setup in Maya?



Cheers

Unfortunately you can only control the radius with the value of the texture.
Also to exclude an object from the dirt map you will have to use the Connection editor (connect the object message to the exclude of the dirt texture). The Exclude slot that you see in the UI will only show you which object you have excluded. The map button doesn't work this is Maya UI limitation which we can not change.

The formula is this:

	float rad=radius;
	if (texmapRadius) rad*=texmapRadius->EvalMono(sc)*texmapRadiusMult+(1.0f-texmapRadiusMult);

i.e. the texture multiplier is used to blend between the texture value itself and 1.0, and the result is used to multiply the radius value.

2.Exclude section setup in Maya?

As Zdravko explained, you can just connect nodes to the respective set.

Best regards,

Thank you both of you for your replies.

I will try to see what I can do with these info,If I succeed in emulating the formula accurately I will post here a screenshot to help others as well.
