athomas Posted August 30, 2003 Share Posted August 30, 2003 Hey guys, I've written a simple X-Ray shader in VOP's Houdini 6.1 build 101. Now I have one problem though, I'm getting small artifacts when rendering, if I remember correctly Mark Elendt: caused by 'No numbers', but can't figure out where my problem lies. Any help greatly appreciated. Andre PS. Marc I don't seem to be able to upload a 164kb hipnc file! Quote Link to comment Share on other sites More sharing options...

FrankFirsching Posted September 1, 2003 Share Posted September 1, 2003 Well, most of the artifacts are due to the reason, that you are using the preview-settings renderer. If you create a "real" mantra output-OP, the artifacts are mostly gone away. Note, that you have to create a camera in your scene too, else Houdini won't use this ROP. The artifacts you notice are not caused by your shader. It is due to the sampling mantra is performing. You can see the same errors when using the "VEX Super Material" and setting the "Alpha Para" and "Alpha Perp" to a value smaller than one.
