Hi, I try to assign a texture to a shader to make it like a matcap in zbrush (i've seen it's possible on a video) but when I choose the texture, instead of applying it to the selected channel, it simply send me back in the shader editing windows (which is reset, so it's not even even keeping other changes) no warning nothing to point of what could be the problem, any suggestion to fix this ?
