Jouk Posted June 30, 2009 Share Posted June 30, 2009 hi as mentioned in the modelling forum, i am working on a L-system project ( vines ). i have built up my L-system vines but at the texturing stage i encountered a problem. Please take a look at my screenshot leaves are being generated at using a J value ( A leaf geo input into the L-system ) but i cant texture them seperately. If i add a material in after my L-system , my leaf color will be overwritten. is there a way to seperate them and texture them seperately? but still keeping the Leafs position generated by the L-system.

Jouk Posted July 1, 2009 Author Share Posted July 1, 2009 how do i group them? sorry i am not really good at houdini since i am animating the generations , i went to the last frame and off my leaves , select my vines and group them ( by points ) as my vines are skeletons , it works but if i move the timeline back , the vines dont get textured correctly. Please take a look at the .hip file. Vine_v018.hipnc notice the highlighted vines ( those are the grouped ) so those that are not highlighted are using my leaf texture. - Jouk Quote Link to comment Share on other sites More sharing options...
anim Posted July 1, 2009 Share Posted July 1, 2009 (edited) the groups for leaves are automatically created for you you can then create group for everything else in compine tab of group node ant then use this groups to filter the operators downstream so there is no need for splitting and merging your network see the file ps: this is 2d tree but if it were 3d it is better to create uvs for leaf before it is connected to lsystem it is a good idea to do it here as well unless you want the texture to float also keep in mind that true displacement can cause you some problems and slowdown, not much but if you do not need them you may consider to use bump only and do you really need 88x88 pixel samples for micropoly render? (i have turned them down to 3x3 for the file to get faster feedback for test renders) Vine_v018_fix.hipnc Edited July 1, 2009 by anim Quote Link to comment Share on other sites More sharing options...
