Glass 2.9! help please

Hello everyone! I’m a beginner and learning Glass texture! I’m watching this video below and Andrew the guy says glass is very simple by increasing transmission and decreasing roughness… “Tada!”
I don’t think so. I cant get it to be transparent. I’m using Blender 2.9. Is that why?

Thank You

below is video and my screen shots

If you’re using Eevee, you need to turn on refraction.
Then go to the material setting, turn on refraction, then change the Blend Mode to anything that work, if you have alpha.

First off, your IOR value should not be 0.0. Some people assume the default value should be 0.0, but this is a specific case where it needs to be set to a realistic Index of Refraction for glass. Different types of glass have different IORs, but a simple 1.5 should work well for you.

Next, part of it is going to be that you are using Eevee. Eevee uses Screen Space Refraction which is a rendering trick that, I think, gets you single-bounce refraction that has specific limitations. If you want accurate refraction and physical accuracy, you should use Cycles. If you still plan on using Eevee, follow @lehuan5062’s instructions, but you’ll also need to set the Refraction Depth to something above 0.0. See the section of the manual for Screen Space Refraction for further info:

Best of luck and let us know how it goes!


Thank you All! Yes! very true. So I got it. I’m now using cycles gpu and added a hdr, z rendered view. I appreciate your help guys.
