Hi, Can someone explain the purpose of creating a thumbnail. I am under the impression that the node is used to make changes to the image and the 3D viewport shows us the output.
You will use it in the next lesson of this chapter. The thumb nail becomes the icon for the brush. The texture itself becomes the brush.
Hi Hanzo, A thumbnail will take up much less memory than the full texture which is why I generate one. This method is one way. If you're using 4.3 or later, Check out this video I made a couple weeks ago from 3:15 https://www.youtube.com/watch?v=FHu6X_N3qjU
