I been experimenting with different render engines for Blender and thought I would share my first set of results. My focus has been animation and motion graphics on a laptop. So trying to get the best look in the shortest amount of time.

Renderman was the only one that got the glass right, the realistic glass bends light a lot. But it takes ages to render
i'm guessing the ball is actually meant to be hollow made of thin glass, and they couldn't find the setting to turn that on in renderman. cycles can render glass spheres with ease. so should all the others. refraction has been a staple in rendering engines since the 90s.
ive used multiple render engines so far, including renderman. The thing is, there is no option to make it hollow, it has to be from the mesh, very renderengine you have is basically a different material, while the mesh stays the same. Thats why it's quite easy to compare them (ofc you have to get all the settings rigth, like ligthing in cycles is compleatly different from eevee. Rendermans sky is created differently than cycles too)
Yeah, Renderman was very difficult to get right (And I didn’t in this case), and that is basically me using it for the first time. The mesh has an inner an outer wall, so there is thickness. My Renderman results looked like a solid glass sphere. I tried to find a setting for thin walled reflection and refraction, or something to tell the material that it was hollow.
I definitely want to experiment with Renderman more. It is the perfect way to learn a lot of theory around rendering.
Oh that's odd, have you flipped the normals of the inner sphere? If you rendered renderman in blender 2.8 please tell me how you installed renderman. I've had it working in 2.79 but it doesn't want to work in 2.8
I did check the normals, but they were correct. Wierd. Anyway, yeah it was Renderman in 2.79. I was looking on the Renderman forums, and it seems the commitment to Blender and 2.8 has cooled somewhat. Not sure when we can expect a 2.8 update.
