Clean a face from its texture

[Quadear]

Hello,

I'm trying to do something simple on paper : I want a mesh with it's to face textured, but the rest of the mesh intact.

On paper, i would only need to put some UV coordinates on the top face's points, and uvs that invalidates the texture on other faces. But when I do that, the original color of every other face is still altered.

I thought setting uv(0,0) would be enough, but it's not.

Does someone know how to do that please ?

not sure to understand what you try to achieve ... here's a box textured on a single face : http://www.babylonjs-playground.com/#OTFI8#2

(not sure your texture can be downloaded in the PG also)

The same with different colors and textures per face : http://www.babylonjs-playground.com/#OTFI8#3

The vertex color is mixed to the texture color, so if you want to keep the textured face with its original color, just set this color to white.

yeah, i was trying to do exactly that, not sure why I wasn't able to do it myself. TY

Hey, new question why here:

http://www.babylonjs-playground.com/#OTFI8#4 the red is red-er than here http://www.babylonjs-playground.com/#OTFI8#6 ?

Just applying the texture changes the color on all non affected faces any way.

yep, actually it applies the texture also on all the other faces, but with an uv of (0,0,0,0)  so the material shader computes the color differently. Maybe this is tweakable by some material property

here's an extra emissive color : http://www.babylonjs-playground.com/#OTFI8#7
