Hi,


I just tried for half an hour without success ..

How can I group only the border points of a poly grid? The group SOP in 15.5 just does not seem to work!

I'd like to select all border points so I can feed them to a following mountain node so that the mountain's displacement is applied only on any interior points of the grid.

I'm puzzled what I'm doing wrong ..

Any input welcome!

It seems just to work fine here, not issues.

hey ..

thanks for the input.

I have just tried again before seeing your post. I discovered it was an issue with the display of the selected points. aren't the selected points displayed yellow or an other color? in my case, all points are highlit the same blue, which is pretty confusing..

Ok, I'm onto something.

I'm trying to do the same thing on multiple prims in one go. Seems I gotta use a for loop for this and cannot do it in one step! oh boy.

jep, that was it. it's working now.

had to use the connectivity sop to separate each incoming prim (create a prim attr) and use that attr to for loop thru each prim to do the border group thingy.


thanks for the inputs !
