Prman And Raytracing

[lorduk]

can someone set me up with quic tutorial - just that I could get my first raytarced image done, so I could start making some sense into this

BTW what is up with that there is on trace VOP?

but there is gather, reflect and refract?

after hours in documentation I have figured out to hand fix my rib

the line I need to add to every object that I want be "seen" by rays is

Attribute "visibility" "trace" [1]

now how can I include this inside houdini, I bet it something like including part of an external rib (just to make thing interesting, but how to do that )

OK figured this one out as well

object level, render tab, pre-include -> dough :oneeyedsmiley02:

Now is there any way to create raytracing shaders in VOP's? at the moment I am just writing them in notepad - nad a bad thing but if need something simple it is easyer to tweak inside houdini

Hey Kaspar,

In the PRMan ROP, under the "Specific" tab, there is a field labeled "Visible Reflection/Tracing". Add the objects you want to participate in ray tracing to that field -- either as a list of objects, or groups/bundles.

Cheers!
