TextureUniform not working in material

for the moment we can’t use textureuniform in material :

it’s not working, but @lilleyse managed to make it working in this discussion :

I tried to make it work in my example:

but it’s not working!

maybe there is a bug ?

The line
arrayBufferView: [1,0,0,1],
should probably be
arrayBufferView: new Float32Array([1,0,0,1]),
