Korhon Posted March 25, 2008 Author Share Posted March 25, 2008 Did try the search engine But in the example file that you found its not using the uv from the object. Its using a boundinbox to project the texture to the grid. I have a object that is made in maya and uvmapped. How can i use the uvmap that comes with the model? And also when using the pointsop to add color to the geometry you have to have a hires mesh to get all the fine details from the texture.? Is there a different approach thats not using the pointsop to create color atributtes? Maybe is just me not understanding how this setup realy works Still new to Houdini! Thanks!

symek Posted March 25, 2008 Share Posted March 25, 2008 (edited) Ok, sorry than. It goes almost the same way. You can replace $BBX [Y] variable in expression (PointSOP) for $MAPU [V], or add ColorPOP with similar way. I turned off Point SOP and applied color in POP. Turn in back on to see the first path. I think there are others way also. Expressions are little slow. It could be a problem with heavy geometry. Perhaps inheriting UV by particles and applying color in VEX would be better choice...
