Group Node issue


Recommended Posts

Hi :

I was trying to separate my points into two groups by the rand ($PT) >0.98. I can see that there are two point groups created from the group small node, but I can't change the point sizes individually from it's own vop sop node. It always only keep one size of my point. I would like to have the points from the group Large to become bigger but no success.....

Could you please help me to see what I did wrong....

And if you can also help me with the new group nodes in Houdini 16 I will be so so happy. I couldn't finish this old tutorial with the Houdini 16 due to the new group node and I just can't apply the expression to the group expression node. That's why I have to open a old file with Houdini 16 and copy the old group node into this file.

Thank you so much for your time..

Please help me .....
