Earlier in the year I did a little tutorial for Blender on how to make a mushroom in 9 minutes on Blender. I realise, of course, that it would take a beginner more like an hour to do it, but the point was that Blender is actually not that difficult if you don’t try and learn how a bit at a time.
Now a couple of people have asked me to go further with the tutorials, and, to that end I have produced an accompanying tutorial on how to texture that mushroom.
The result would, for me, be an initial texture which I would improve over the next few days until it became a thing of beauty. This tutorial is, however, just meant to demonstrate the principles involved in doing so.
So…that should get you started..
