I want to mix the color output of the ramp with the color output of another ramp based on a certain color range. For example, the second ramp should only mixed in if the Cd value of the first ramp is less than 0.1 (the whites only). So I thought it would be possible with the color mix node but I don't know what variable to put in into the bias amount. Or is there another way?

Hmm, so easy :-) I thought that the rest vop in the shader is doing the same as in the SOP context. Thank you

I have made a material for a simple ball. But it seems that the material changes if the geometry will be deformed. For a test scene I will be have soft body balls and want to use a procedural material with noise but the noise pattern should not change as you can see in the screenshots. It just should follow the stretching ball. I think it has something to do with the procedural material which I have put together. Would be great if someone can have a look. Thanks test.hipnc

But do I have access to the presets of the physicalSSS vop in the default surface shader?

hm, it seems that the PhysicalSSS has more functionality than the SSS section of the surface model. If I use a Mantra Surface Node how can I easily implement the PhysicalSSS vop? I'm not a shader guy and wouldn't create a shader from scratch.

Thank's edward. That's what I'm looking for

I want to creat a procedural staircase. Has anyone done this and can help me? Thanks

Ah, thanks, I have used the volume viz node to after loading in the bgeo. So with that, I have also a colored representation in the viewport. Thanks a lot

For example, I have used the shelf tools to create a sphere and a pyro flame. in the DOP I/O I can export my simulation frames as bgeo. There is a DOP Import node which "get's" the visualisation from the DOP network. But, have saved my bgeo files and don't need the DOP anymore. How can I read in/display my visualisation data in the viewport?

I've tried to install it as described on OS X 10.8.5 and Houdini 12.5.469. It seem's that it isn't recognized by houdini because I don't have the sop nodes and don't get any error message. Any ideas?

... they are going open source ... COOL ... LOL

is there a way to copy a geo (for example a Tube) on each fur in a fur system and match the deformation from the furs?

I want to simulate falling snow with particles and maybe with an attached mini-geo which makes pleasing snowflakes. I came up with the idea to displace the landscape incrementally for every particle touching the surface for a certain amount. So that the particles are just for the forming of the landscape and after that to make a nice render of a winter scene. Can anyone out there point me in the right direction or give me some hints to start with? Thanks

I would like to create a brushed steel material base on the mantra surface shader, or from scratch with the lighting model. Any suggestions how to create this procedurally without a texture? Thanks Thies

I will testing for you too
