Trying to fit a simple image as a planar XZ UV map on a CreateLathe object

Questions
1

I am trying to recreate this simple shape which is perfect for my needs (Pinball Bumper Cap)
https://www.babylonjs-playground.com/#D2CWET

But now I have no clue as to how to fit a planar uv map on top of it.

Here is what it is supposed to look like (made with XSI)

Any clue?

As a reference here is the model in context (the uv seems to be rotated 90 deg or spherical map?)

Have you seen these resources?

They’ll likely help.

Its a matter of recalculating the uvs based on vertex positions https://www.babylonjs-playground.com/#D2CWET#1

Note line 47 - the need to make your bumper updatable to update uvs

Sorry, this is not.

In many ways @PirateJC pointed you to the right place. You do need to know about the vertex data structure of a mesh and how to update it in order to solve the problem they way I did.

I understand John but as I come from a software world, I was under the impression that I was looking for a simple PLANARXZ_MODE or something simple like that.

This being said I made a nice function from your script and now i can do it on the fly thanks to you.

here is the result BTW

This solution is Babylon.js feature material.
Projecting UV from axis is something very useful in Blender.

Thanks
