peliosis Posted May 22, 2006 Share Posted May 22, 2006 I can't see too much on this image but it looks like unsubdivided cage is Are you sure you have only needed objects visible? It doesn't look like a graphic driver problem to me. Quote Link to comment Share on other sites More sharing options...
khasperha Posted May 22, 2006 Author Share Posted May 22, 2006 hello peliosis i'm new with houdini,look at the another picture..it's a random prob. Quote Link to comment Share on other sites More sharing options...
khasperha Posted May 22, 2006 Author Share Posted May 22, 2006 the prob. is the "white point" on the picture Quote Link to comment Share on other sites More sharing options...
peliosis Posted May 22, 2006 Share Posted May 22, 2006 the prob. is the "white point" on the picture 27868[/snapback] The white spots is an artifact, but what are the regularly placed dots?? Try the trick and increase near param in camera view tab to 1 or something, this usually kills most artifacts. I'm not sure why there are no splatches on the body?

khasperha Posted May 22, 2006 Author Share Posted May 22, 2006 hey peliosis, i think i found the prob. well, after having created a group and a shader for mapping a part of my object .the prob is that the normals "flip" when i move the camera! my test was mapping with "two sided" and in 2 differents colors. finally if a move my camera sometimes there is color 1 and another color 2 .... very strange is there a solution for that?...

DaJuice Posted May 23, 2006 Share Posted May 23, 2006 Kinda looks like extraneous geometry to me... But what drivers are you using on your 5900? 8x.xx are known to have problems in some apps. I'm using 77.xx drivers on a 6600 without any serious glitches. Quote Link to comment Share on other sites More sharing options...
peliosis Posted May 23, 2006 Share Posted May 23, 2006 Sorry, I have another look at the title...I thought your pics were taken from the viewport, not rendered:) That is a whole different subject. That's the life of rush answers. Quote Link to comment Share on other sites More sharing options...
khasperha Posted May 23, 2006 Author Share Posted May 23, 2006 hello DaJuice, hello peliosis DaJuice, i'm going to install 7x.xx driver under fedora 5 and i see... thanks peliosis, "I thought your pics were taken from the viewport..." Yes there are! if i do a mantra rendering at this moment the result is sometime good sometime bad .. thanks you a lot! Quote Link to comment Share on other sites More sharing options...
old school Posted May 24, 2006 Share Posted May 24, 2006 This is probably a real stupid question but are there two sets of primitives in there? Try turning on prim numbers in the viewport and have a look. It wouldn't be the first time I got duplicate sets of primitives while modelling...
