CSN0309 Posted March 21, 2011 Share Posted March 21, 2011 hi~ guys looks like i got a small problem on the edge area.. i want to put noise in colortranfer area by using attribtransfer node. 1. i have used attribtransfer node to transfer color from one object to another(red area) 2.apply attribcreate node to "record" the red area and import as parameter into SHOP network 3 and use multiply to restrict the noise area, But, my problem is,, by doing this way, i always get a sharp edge,,,,so has anybody got idea how to make the edge soft????? shape_edge_113.hipnc Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted March 21, 2011 Share Posted March 21, 2011 The sharpness is coming from the noise that is multiplying the attribute. It looks like Alligator noise? Try reducing the roughness of the noise and also check out the frequency. If that doesn't get what you're looking for then maybe try another noise type like Perlin.

3__ Posted March 21, 2011 Share Posted March 21, 2011 In this case, try using 1-$CG instead... see attached. shape_edge_2.hipnc Quote Link to comment Share on other sites More sharing options...
SpencerL Posted March 21, 2011 Share Posted March 21, 2011 In this case, try using 1-$CG instead... see attached. A big issue is that transferring attributes is geometry resolution dependent. In order to get the noise detail in your transferred color, you will need a much higher res geometry. Quote Link to comment Share on other sites More sharing options...
lukeiamyourfather Posted March 21, 2011 Share Posted March 21, 2011 Yes and no, point clouds can be used instead of actual geometry to store attributes. Or just add noise at render time like you already are if you are just after noise and not additional attribute resolution. Quote Link to comment Share on other sites More sharing options...
