How can I get only textures (with out shaders) from rendering image in Blender 2.8? I want to get Only texture with out shaders from rendering image.

In my rendering image.



I want to output a texture-only image like displayed inside the red frame of this image.

I want an image that looks like Solid in Viewport Shading and the colors are from textures.



Screenshots are not an option, because I want to match the size with the rendered image.

I can write Python, so I'm more glad if I can get it with a script.
1-You can enable color pass in view layer settings. And access it in compositing.

2-You can do screenshot of the solid with right size by doing Viewport render image.
Its in view menu of viewport.

  Just use the texture color directly to the surface output, with no
  shader in between. – lemon


With Node wrangler addon shift-click on texture in material editor to show just texture.
Or connect texture to emission shader and this shader to output node.
