Learn if a mesh has the second UV channel

Questions

Hi guys,

sorry for a noob question. How can I learn if a mesh has the second UV channel? Is there a method inside Babylon to define if a mesh has the second UV channel or get a list of UV channels in a mesh?

Thank you

You can use mesh.isVerticesDataPresent(VertexBuffer.UV2Kind) to know if the mesh has this attribute data setup

Thank you for a quick answer, unfortunately this throws an error that VertexBuffer is not defined. The editor then added the following line automatically:

const { VertexBuffer } = require(“babylonjs”);

But then the console throws another error that require is not defined.

What am I doing wrong?

If you’re writing vanilla browser javascript, you should be able to use BABYLON.VertexBuffer.UV2Kind like on the playground. :slightly_smiling_face:
