I'm done with college for the summer, but have been working on a new musical animation in my spare time. It's going to be a short percussion solo rendered with Blender's new 'cycles' engine. I like how easy it is to get good looking materials, but have come up with a noise problem.
This is a close up of one of the tom drums. I like the lighter scratched look of the top picture, but get all kinds of annoying noise spots.
In the bottom picture, I discovered I could get rid of the problem by minimizing the glass shader's Index of Refraction, but for some reason my scratch texture showed up clear and gross.
One thing I don't like about the top image is that you can also see the higher IOR warping the background. I don't think a real drum would do this.
It looks like I need to go over more cycles tutorials!
