I figured out how to use several materials on a mesh the other day. I have a remade cave with two materials but I am not happy with the texture and need to remake it. And probably the cave, too, as it's a bit big. I did nothing on it today since I had a doctor appointment with my ordinary doctor. He is giving me a referral to a medical marijuana clinic (I had requested it as I am not wanting the neuro's painkillers). He pretty much regards me as a hopeless case, in a compassionate way. I had brought a physician's orders form and we filled it out. It's a "do not resuscitate" thing. He is dubious of the neuro's efforts since it just adds up to a lot of effort and expense for no practical good. Getting into and out of the office was a huge effort, which is why I've done nothing else today. I did turn my heat on for the first time as the high was in the 40s and I've been really cold lately.
