dennisvolkerts Posted May 8, 2013 Share Posted May 8, 2013 Hi, Try to use voronoi fracture in Houdini 12.5 but my scatter doesn't pick up my red color while im using Cd at bias 1 anyone? Quote Link to comment Share on other sites More sharing options...
dennisvolkerts Posted May 8, 2013 Author Share Posted May 8, 2013 ok thanx... i know the problem!!! its my paint node!!! revert to default doesnt help, reinstalling doesn't help either i know i is because my paint node doesnt even work on the attribute tranfer node as well anyone?

dennisvolkerts Posted May 8, 2013 Author Share Posted May 8, 2013 even if i paint on the edges of (for example a cube) it paints the whole row and collum in that direction. Anyone who fixed this problem? or has the same isue before? please help!! its not only this computer so it isnt my machine thnx Quote Link to comment Share on other sites More sharing options...
melazoma Posted May 9, 2013 Share Posted May 9, 2013 Without an example hip file, it's hard to say for sure. But is does your cube have any divisions greater than 1? The Paint node allows you to paint per-point, so if you have very low or no divisions on your cube the painted color would get stretched / interpolated to the closest neighboring point.

Hudson Posted May 9, 2013 Share Posted May 9, 2013 Hello Dennis! About the paint problem it does work just fine for me. I tried several times to paint the cube in different colors and there was no snapping or so. I would probably check your preferences for any snapping or graphics. But it seems weird. The problem of the scattering not working is because "cd" isn't an Attr but "Cd" is . Easy to forget Cheers, Hudson paint problem_fixed.hip Quote Link to comment Share on other sites More sharing options...
sadhu Posted May 9, 2013 Share Posted May 9, 2013 Write Cd instead of cd in alternate attribute param in scatter sop. It will work. 1 Quote Link to comment Share on other sites More sharing options...

Matt_K Posted May 9, 2013 Share Posted May 9, 2013 Hi Dennis! On the box parameter pane you should find a checkbox : Consolidate Corner points. If you uncheck that, the paint node should work as expected. I'm not sure if this is a bug or the way it's meant to behave? Matt. Quote Link to comment Share on other sites More sharing options...

dennisvolkerts Posted May 9, 2013 Author Share Posted May 9, 2013 (edited) Damn!!! still having a problem scattering the color "Cd" scatter Cd.hip Edited May 9, 2013 by dennisvolkerts Quote Link to comment Share on other sites More sharing options...
WesleyE Posted May 10, 2013 Share Posted May 10, 2013 (edited) A quick solution now would be to create a varmap for the color (Create attribute Cd) and then remove all the points with a delete sop $CDX > 0.5[/CODE].And then scatter around that.It seems that there is something wrong with your geo that your are scattering on. Switch it around with some other geo and you'll see that it will work. Edited May 10, 2013 by WesleyE Quote Link to comment Share on other sites More sharing options...
anim Posted May 10, 2013 Share Posted May 10, 2013 on your geonetry you have 2 Cd attributes one is primitive one point scatter prioritizes primitive attribute to generate distribution so it seems to you that it isn't working simply insert Attribute SOP before Scatter SOP and write Cd into Primitive/Delete Attributes to remove primitive Cd and therefore force Scatter SOP to use point Cd which you've painted Quote Link to comment Share on other sites More sharing options...
kleer001 Posted May 10, 2013 Share Posted May 10, 2013 (edited) Exactly. See attached. I'm lazy and using a prim SOP, but the action is still the same. scatter Cd.hipnc Edited May 10, 2013 by kleer001 Quote Link to comment Share on other sites More sharing options...
Doum Posted May 10, 2013 Share Posted May 10, 2013 There is a bug in the last build version 12.5.393. I've encounter some problem using the alternate attribute : Cd when doing some RnD. I backtrack to 12.5.376 and it's working. Quote Link to comment Share on other sites More sharing options...

Yeah... voronoi Visualize pieces multiple times was the problem!!! Using the primitive sop worked for me! or just disabling the visualise pieces.. How to work with the attribute sop for fixing this?

anim Posted May 11, 2013 Share Posted May 11, 2013 ... How to work with the attribute sop for fixing this? it really doesn't matter what you use to remove primitive Cd attribute, but for Attribute SOP usage do what was said before ... simply insert Attribute SOP before Scatter SOP and write Cd into Primitive/Delete Attributes to remove primitive Cd and therefore force Scatter SOP to use point Cd which you've painted scatter Cd.hipnc Quote Link to comment Share on other sites More sharing options...
kleer001 Posted May 15, 2013 Share Posted May 15, 2013 Attribute SOP is faster. Things like the Point SOP, Prim SOP, Color SOP, are all wrappers that make it easier, but more laggy. Quote Link to comment Share on other sites More sharing options...
nickol Posted July 25, 2013 Share Posted July 25, 2013 I'm newer, but i had same problem. first apply background color (0,0,0) to entire object, then paint red (1,0,0) with foreground. problem solved! Quote Link to comment Share on other sites More sharing options...
