How can I delete a class with a primitive value of 13 based on uv's ? Also, how can I find the size of a uv island, I don't want the bounding box of the area, rather the actual size of the island ?

Is it not possible to have a UV layout sop after the file; then get the island attribute and use that in a forEach sop and then move each island to a different udim using a transform sop within the foreach sop ?

When promoting uv from vertex to point as P, my mesh becomes completely tangled after the vertex split; as your example @konstantin magnus ? It would be because the UV are outside of the 0-1 ? v@bbox_min = getbbox_min(0); v@bbox_max = getbbox_max(0); f@fituv = (float)fit(@uv,@bbox_min[0],@bbox_max[0],0,1); f@fituv = (float)fit(@uv,@bbox_min[1],@bbox_max[1],0,1); f@fituv = (float)fit(@uv,@bbox_min[2],@bbox_max[2],0,1); The above is getting me the bounding box for all three values for the min/max but how can I set them so that the UV fit within the 0-1 range. The above was what I had planned.

I don't have a vector variable for the first parameter; only two detail attributes which I split and promoted from the vertex attribute uv. I tried the @P attribute but that won't have any effect on vertices; only attempted because it's a vector.

I corrected the parameters which I posted in my original post. Although the fit() function has five arguments; the first argument is what I don't know if what I'm entering is correct ?

I'm promoting the vertex uv attribute to each their own detail attribute using an attribute promote; except now I want to fit the values from these two detail attributes. Therefore I'm running the following code in a detail wrangler; although I'm not getting the result which I want ? vector newUV = fit(1,@min_u,@max_v,0.0,1.0);

Actually, I do have multiple points with different arrays. Are you saying, rather then a detail attribute, I use a pointattrib; since I want to get the attribute array for multiple points ?

One question, from the way I understand, this can be run on points; rather then detail ?

Right, thank you This is perfect and helpful.

This is good, except; if I blast the group, I'm still getting primitives, rather then only points ?

How can I create a group using an attribute for which I want the group to be created from, setPointGroup() doesn't accept attributes as an argument ? I tried looping over all the points in an attribute array using the ForEach loop then appending them to a new group, but that doesn't work as the new group just contains all the points for the mesh, rather then the points from the attribute array for one point. I n other words, take one point from the mesh which contains an attribute array and for that one point create a group for all the points for that point in that points attribute array ?

I have a bunch of points, lets just say there are thousands. If I blast just one point, with delete unselected; obviously I will just have one point in the view port. I have a wrangler with a variable with a nearpoints() expression. For the point which I'm not deleting with the blastnode in the view port, I also want all the nearest points for the current point which is not being deleted to be seen in the viewport, which is in an array ?

I have an attribute on points, and I want to blast all points but a single point but also have all the points which belong to the point array to be included.

When blasting a point using the blast sop is there an expression which I can add to the blast sop to include the number of the point being blasted to include the points from an attribute array in the blast sop ?

It worked for you, that is all I want is to have it work on my end ?
