rotate DetectedTouchST results?

[Ruthven Ravenhurst]

I'm trying to make a color picker for a HUD I'm building. I'm using Mesh Studio to build the link set, and convert it to mesh. The problem is, the coordinates for it is returning for the color seems like the face is rotated, even though the texture offset is correct for the crosshair I put on it. Do I need to rotate the vector or something to make it work?

I'm using the script here (which works normal on a legacy prim), and I changed the face numbers to the appropriate faces on the mesh

I tried rotating the prim for the color pallet before meshing it, and i get the same results. I also tested the other faces (luminosity, and the alpha) and they also seem to be rotated

You can see in the snapshot that I'm clicking on the lower part of the color pallet, and the color should be gray, but the preview panel and brightness panel are showing yellow, as if I clicked about the same point, but along the top of the pallet instead of the side

To show you more of what I mean, in the first snapshot here, I clicked on the top right, where it should be red, but it's gray instead. 

In the second snapshot, I click the bottom right, still gray

In the third, I click yellow, I get pink

Try multiplying your vector by llEuler2Rot(<PI/2,0.0,0.0>), so you have

vector Color = llDetectedTouchUV(0)*llEuler2Rot(<PI/2,0.0,0.0>);

I think that's right.  Experiment.

I actually got it to work somehow, I kept playing around with the different axis placements in the calculations.

in the original script it's getting the HSL as:

vector v = llDetectedTouchST(0);
            HSL = <v.y, 1.0 - v.x, HSL.z>;

but in my fixed version it is:

vector v = -llDetectedTouchST(0);
            HSL = <-v.x,1-v.y, HSL.z>;
