I am using blender 3.0.0 Beta
I have a plane with many vertices and want to raise one of the vertices higher than others using geometry nodes. enter image description here I have two approaches : 1- vertex groups 2- weighted vertices
Whatever you can help is welcome. I have tried to select and separate both ways and all of my efforts have failed so far. enter image description here Please help to understand how the selection works in Blender 3 geometry nodes. Also the raised vertex at the moment is a manual raise 😊 So the ideal output would be : enter image description here

  • $\begingroup$ What is the reason for downvotes ? I have a vertex in a plane that I want to raise it using geometry nodes. Isn't here the right place to ask this question? please explain your downvotes. $\endgroup$ Nov 25 '21 at 4:43

    $\begingroup$ Hey Spongebob - don't be angry. Just take it as it is. It is a waste of time to even think about it. If you are longer here you might even make worse experiences. But...there are also a lot of really kind, helpful people here...and some are kind of genius...you will see. And that's worth it!! $\endgroup$

  • $\begingroup$ what i can think of is...your question is about Blender3.0beta. And some here take the "rules" which are in here VERY strict - they seem to think the are the sheriffs here - but they don't treat people equally - they just do this on special people...mostly just on the "new ones". So the "official" rule is, that this here is just for officially released software...BUT of course you will find a lot of "still" open and answered questions about Blender 3.0 $\endgroup$

  • $\begingroup$ @Chris I didn't know that only questions from stable versions of blender are answered here. I always use development version :( $\endgroup$ Nov 25 '21 at 6:46

Use Index and Compare Floats node for selecting particular point.

In this example 70th index is selected. enter image description here

To select only a vertex group you can use this node setup:

enter image description here

Press this button enter image description here in the modifier to toggle it to attribute.

  • $\begingroup$ Thanks Harisreedhar Is there any way to check VertexGroup name or Weight value of a vertex ? $\endgroup$ Nov 25 '21 at 6:33

    $\begingroup$ Did you mean importing vertex weight into GN and use it as selection? $\endgroup$ Nov 25 '21 at 6:38

    $\begingroup$ In that case create float field in Group input node and from the GN modifier tab you can put vertex group into that foat field. $\endgroup$ Nov 25 '21 at 7:08
