Hey guys

Is it possible to connect textures (and extracted values) to the principled shader? Like I have a texture with Metallic in the alpha channel, and I need to split the texture into RGB and A and would like to connect to the respective ports of the principled shader, but on the viewport I see no change. When I add the textures on the textures tab, it's OK, but then I can't split up the texture into RGB and A. At the moment it's not an option to build up the shader on my own

Thanks in advance

You can try to use Textures to drive inputs, but that seems flaky. It does not work with some of my maps.

Try using a Texture node. Set the signature to RGBA and then use a Vector4->Float node to obtain a float value for each component of the signature.
