Hi,

Is it possible to see textures in the viewport if I use Nodes? I attached my hip file.
In blender I can do it.

if you put directly your texture in the principled shader you will have an opengl preview
otherwise you can edit the rendering parameter and add opengl preview from here

Thanks for the reply. I know about this thing.
I just think about something more complex. For example to mix 2 textures with Noise. And see the result in the viewport.

In blender I can see such a result in the viewport. And it speeds up shading process.
