rotate a material

[ramsestom]

I need to rotate a material applied to the face of a cube. Is there any function to do this with only one function call rather than iterating over the textures of this material and modifying their "wAng"? 

Or alternatively, is it possible to rotate only a submesh (a face of a cube) from a mesh?

Here is a post from 2014 which tells how one user accomplished this. The post doesn't provide the specific code, but should provide eenough info to accomplish rotating a texture on a cube.

you can use the shaderBuilder too if you Intersted i can make a pg sample for you

hope this could be help

These playgrounds would be excellent documentation examples for ShaderBuilder.

He uses the "wAng" properties of the textures. But this is not an ideal solution when a material is composed of multiple textures as, as I said, it requires to iterate over each texture of the material to rotate the full material....

Thanks. But I am actually using the haxe port of babylonjs (babylonHx) that do not yet include the latest changes in babylonjs. So I can't really use the new shaderBuilder (anyway it is probably not really the function I need because I just need to perform a "one shot" material rotation and not a dynamic one. So I just need a function to rotate the submesh of my cube face, or only its UVs or else, a function to rotate a material (by rotating all the textures of this material)).

I don't use BabylonHX, but it does appear they have ported shaderBuilder.

If you haven't already, I would see if shaderBuilder works.
