Texturing Ribbon

[Dado]

Hello everybody,

At first,many thanks for all BJS devs and team behind this great framework!

Q: How can be "irregular" ribbon textured,that texture is not stretched?

(per example- simple leaf shape made of Quadratic bezier curves;texture is squashed on its tips..)

Tried to find answer on my own; but had no luck till now,

it could be cause of me and my capabilities;

so,if one exist please do redirect me and I do apologize for asking it again..

 

Thanks in advance!

When you use a ribbon, the UVs are computed by default to be stretched on it as if the ribbon were unwrapped. This is why they can differ from what you expect when you fold it to some specific geometry.

That said, you can pass your own UVs as a flat array of Vector2 (each array element being the UVs of each ribbon vertex) with the optional parameter "uvs" : https://github.com/BabylonJS/Babylon.js/blob/master/src/Mesh/babylon.meshBuilder.ts#L141
