Procedural Edge Loops/ Group Expand/Contract

In this video we talk about 4 new nodes to help speed up your procedural group workflows. 

Group Expand - Grows a group selection based on a number of iterations
Group Contract - Shrinks a group selection based on a number of iterations

Group Edge Loop - Turns an edge group into the corresponding Edge Loops
Group Edge Ring - Turns an edge group into the corresponding Edge Rings 

You can download these nodes from the SideFX Games Development Toolset Github Page and as always feel free to leave your thoughts in the comments!

    how about ability for edge loop to symmetry adding another loop on other side of the geometry. if you create one edge loop and you want to split it equal to another side of the geometry without using scale tools automatic enable symmetry and loop will be added in other side. poly bridge it will be nice if you can select both source and destination poly/edge and apply poly bridge instead of selecting source and then selecting destination it make modeling slow.But if you can quickly select both it make poly bridge very easy and fast.

      That's a good idea. I'll take a look at symmetry options on selection, but if you select 2 edges that match the loops you want to create this tool will generate them for you. So it might be a good workaround for now for your polybridge example.

    ok thanks

    Hello. Please, create dot loop and dot ring like in 3dsmax for points edges and primitives (with steps)

    this is very slow is there a way to increase its speed?
    maybe use hdk instead of python?

    Would be nice to implement those nodes as a one node. Just set the range from -value to +value.

    This is awesome!

    Do you know if there is there a way to procedural select the longest edge loop of a specific object?

    hello, i just downloaded the stable version but the group edge ring is not there.
