willlinks Posted October 9, 2009 Share Posted October 9, 2009 Hi everyone, I got a problem with transfering color imformation from Texture (or shader) to points. I could transfer the color imformation to points but UV is not not match with one I set up. If some one knows how to match UV position, please help me. I attach a sample hip file. Please have a look. Thank you! transfer_texture_color.hipnc Quote Link to comment Share on other sites More sharing options...
anim Posted October 10, 2009 Share Posted October 10, 2009 ... I could transfer the color imformation to points but UV is not not match with one I set up. ... that's because you are not using uv information in the expression you should use $MAPU and $MAPV instead of $BBX,$BBZ you can find their description here: http://www.sidefx.com/docs/houdini10.0/nodes/sop/point#locals it will look like this (for red channel): pic("../Footage/To_Sops",$MAPU,$MAPV,D_CR) Quote Link to comment Share on other sites More sharing options...

jujoje Posted October 11, 2009 Share Posted October 11, 2009 hey, Depending on what your doing you might want use a vopsop to colour the points since the pic() expression seems to be very slow. I've attached an example file. Julian transfer_texture_color_vopsop.hipnc Quote Link to comment Share on other sites More sharing options...
