How to get a nice glass sphere render?

<< < (2/2)

Hey guys! Sorry for the later reply. The big issue for this image is that it's going to be used in a UI with overlapping graphics, I wasn't allowed to be too much fancy with reflections and stuff. I'm attaching the final output for the client.

The only thing that I wasn't really able to achieve was the "thickness" effect on the edges of the glass ball (like the 2 images attached with bubble/droplets).

BigAl3D:
This is a very tricky look to achieve. The A.i. did a good job of getting the feel of it. Unless you are animating or doing something else that REQUIRES you to get this look by just hitting render, then I'd think of it in pieces that you assemble in Photoshop or whatever. Here, I rendered out the glass ball with two lights and used architectural glass and I added a Fresnel effects to get the center to render mostly transparent with alpha.

I grabbed a simple gold ball of C4D's assets (uses a crazy looking normal map to get the dimples, but I'm guessing a proper mesh would give better results. I thine rendered the not-so-great ball and played with the layers in Photoshop. In the ballpark, but needs work. If it was me, I'd make the glass manually, and then render a ball with a warm and green light to try and get the look.

Maybe this will spur an idea.

I still don't get it why not model a sphere with thickness by modeling a sphere with thickness. :)

The problem with thickness is that the "thick" part was too harsh in my tests
