Another pile of rocks.
I was working on my rock shader today, and got it to a point where I was pretty happy with it. So I appended it to a new scene to test it out… and this happened!
So the issue was saturation and value.
In the original file where I was building the shader, I was in full sunlight, and made the colors quite dark. I had a hue/saturation node in the color chain where I also increased the saturation and decreased the value even more. After appending it to the new scene and setting up a forest with shade, I raised the value to make the colors lighter. Without also adjusting the saturation, this appears to have brought some of the colors above 1.0, which causes them to reflect more light than they receive. Thus the ‘glowing’ rocks.
I tweaked a little, but much more needs to be done to make these rocks work in shadows and sunlight together. Here’s a challenging scene with dark shadows and bright sunlight with the unfinished colors. The moss also needs some attention.
Had a surprising ‘accident’ today, so I went with it:
After watching another of @Mantissa’s great videos (thanks for putting them out!), I was inspired to try playing with hair. Some goofing around, and I decided to go for underwater tentacles.
Not super-thrilled with the results, but it was neat to play with :).
A test render I saved along the way:
And a really early fast test. I lost several of the appealing features of this render along the way, which is sad.
Some beautiful images I will keep an eye on your scetchbook
