I'd like to make a crystal triangular pillar in Blender that looks like the example someone gave in response to a question like mine.

the image in question

I've tried to get it to look like this but just end up with it looking like this

my go at it

Since I do not have to privilige to comment yet I can't ask the creator how he/she did it. Can someone please help me out?

Thanks in advance ;)

  • $\begingroup$ Is this is like a game of spot the difference? Only thing I see different is that you have the order of the last mix shader inverted compared to the example solution $\endgroup$ – Duarte Farrajota Ramos Mar 6 '17 at 23:29

    $\begingroup$ You may have inverted normals. Also, the example solution seems to have a bit more geometry on his crystals than yours, maybe a SubsurfmModifier, or perhaps a Bevel $\endgroup$ – Duarte Farrajota Ramos Mar 6 '17 at 23:49

    $\begingroup$ Oh wow. It indeed was flat shading. After setting it to smooth shading I got exactly the result I wanted. Thanks man $\endgroup$ – ben-e Mar 7 '17 at 0:03

    $\begingroup$ Gemstone Material here is a nice gemstone material you can adjust to your liking. It also entails quite a bit of explaining. $\endgroup$ – J. Brosch May 16 '17 at 15:55

It eens to me that you should add a little more geometry, make sure the roughness value on your glass shader is the same as your examples and the main difference that I see is the lighting setup. The other person is using some sort of image texture as their light source. A very nice touch. Also, I suggest you turn up your samples so the image isnt so grainy. If you have any questions as to how you can do any of this jut ask


I agree that you should add more geometry, and your emission appears to be a little bit more on the turquoise side. Try lessening the green a bit, and adding some more facets.
