solved Casting Rays on transformed Objects

[Pryme8]

So when I bake out the my objects transforms in this scene:
https://www.babylonjs-playground.com/#NAG06Y#26
and try to do my raycast protection, none of the rays hit... which I find odd.
here if I do not bake out the mesh that I am casting from some of the points hit, but they are not being cast from the correct positions, so I am confused.

its been a long day so maybe I am just missing something simple.

trying to make it so I can move my plane or mesh that I am projecting the UV to like i did here:
https://www.babylonjs-playground.com/#NAG06Y#8

Here is what happens when I bake the transforms prior to my sectionMesh function.

I am wondering if its the sectionMesh function that is giving me trouble.
*EDIT*

Nope its not:  https://www.babylonjs-playground.com/#NAG06Y#30
Something is not getting baked it seems.

So I am thinking its not my ray casting that is messing this up, and is actually the sectionMesh method I am using.

Is there a way to split up a mesh out into a new mesh from a range of points?  In this example I am trying to grab out points 0-25 but it seems like even after I do that more buffer data then I anticipated is still present on the mesh.

So Im thinking my UV projection is not working because my bufferData is wrong.

Any input would be cool.

 

*EDIT*

Never-mind I think i figured it out... after looking at it again this morning.  (dumb loop count error)

[Pryme8]

Ok now this gives me a headache...

https://www.babylonjs-playground.com/#NAG06Y#36

if you look at the console, all my rays are being cast for no reason as I stripped out all the vertices data from the buffer that I am looping through
 

console.log(positions.length, "positions length");

for(var i=(skipTo*3); i<(positions.length-trim); i+=3){
}

There is no reason 26 rays get cast.

Well positions.length-trim = 78

because trim is negative

[Pryme8]

whoops... see thats what happens when you don't pay attention.

[Pryme8]

Well then riddle me this:
https://www.babylonjs-playground.com/#NAG06Y#40

Why does this not simply "cut" out the section of the mesh that I want.

Also whats up with the errors coming when you click on the scene, I have no mouse listeners bound but default stuff.

Made a PR to get the Lathe object doing what I need:

I have no error (Just f5 your page, you may have an old event attached)

So I went ahead and used my custom lathe, now for some reason trying to apply the new UV is not working like it did with my initial scene with the star.  I figured this should have been easy, guess I under thought it.

[Pryme8]

ohhh I bet I dont have the mesh as update-able... fml...

*UPDATE* 

it was...
RABBLE RABBLE RABBLE... its always the smallest things.
