In 2.79, I could get easily acceptable quality from the native renderer. I'd like to move to 2.80 but can't get a good quality render from cycles and eevee is far worse.
The files below are an old practice image that used many of the basic techniques that I needed to practice. I'm more interested in technical drawings but needed something a bit more capable than the free Sketchup offered.
Can I get a clean render (no fireflies?), proper clear transparencies, clean reflections in cycles? In blender render, it was so simple. In cycles, I'm having no luck.
To make it easier to show new settings: http://www.bcae1.com/temp/blender%20help/hydrauliccylindertransparenttube01.blend
This will allow anyone helping to change the materials for the tube without having to try to go through the mess I have on the larger file.
Thanks to all who posted.
I think, for now, I've found a solution that will work for me (Radeon ProRender). The controls work as I expect. I'm sure that Cycles works as well or better since I've heard very little about the Radeon renderer but I can make ProRender do what I need it to do for now where Cycles just baffles me. Thanks again.
