Basic question about grouping

[J.Santos]

Hi!

This is a noob question for sure but I'm not being able to do this...

I have a grid, that's my terrain and I've used a group SOP, with bounding set to "bounding sphere" to create a group. Then I applied a mountain SOP. But my idea is to have the group being flat while the rest of the terrain (grid) assume the mountain SOP.

I've tried using the number option on the group SOP, to use the group by expression in conjunction with my bounding sphere. I tried using something like != ch("boundtype")or <> the boundtype or the boundtype size... with no result...

I also tried to isolate my selection, making 2 deletes: one for my group and one for the terrain... but I got a warning flag of degenerate geometry and nothing...

I also thought about using color, but then I got stuck at how to say : "use color A to be flat and color B to be a mountain"...

Any help would be great!

On your Group SOP, go to the "Combine" tab, and create a new group that's the inverse of the group you created. So if your original group was called "group1", put "group1" on the right, hit the "not equal to" toggle button, and a new group name on the left, say "group2".

Then just use your new group.

Thanks Darric!

It was so easy... I guess I was over complicating things...

Have a nice weekend!
