Refraction not visible.

I appear unable to see any refraction attached to a Material.

Im running a MacBook Pro, Early 2013
NVIDIA GeForce GT 650M 1024 MB

Is my problem system related or is there an issue in my setup. image attached.

Thanks for any help.

Hi ,

You will want to use a lerp at the least to get your refraction working properly. Here is some more information from our documentation:

Let me know if that helps.

Thanks,

Hi thanks for the reply.

Unfortunately I’m still not getting this. I copied the example 1to1 and still not seeing any visible refraction in ether editor or view :frowning: . see image.

I see you added in a metallic value. The metallic value will need to be set to 0.

The Fresnel you have chosen in the VectorOps Fresnel instead of the simple Fresnel. In the “Power” input of the Fresnel, you can put a scalar value in that to activate it (5 should be a good number). Let me know if you have any questions.

One again thanks for your reply.

I’m ether missing something very obvious or its a graphics/system problem.

I have tried various methods and followed a handful of tutorials without luck. In the attached image you can see that in my “Content Browser” the thumbnail shows a refracted surface…however in the editor and in game the surface simply appears translucent.

Hey -

Refraction depends largely on the shape and unwrap of your mesh, so it is not unusual to have the default mesh in the preview material window be different than the mesh in the level itself. For a late comer to the conversation could you post your breakdown of your material. Here is my own text refraction which is working fine.

Thank You -

Hi Eric

I have attached one of my attempts “juoolz01 & juoolz02”. I also copied you “Eric_01 & Eric_02” but still no obvious refraction is visible. :confused:

cheers in advance

Hey -

What is your Engine Scalability set at? If it is not there, please set it to Epic and see if the refraction show up.

Thank You

Okay I now feel like an absolute… It worked a charm. Im now reading the manual from top to bottom so I don’t miss a trick!!! :slight_smile:

Thanks again guys I really appreciate your time.

Wow… That problem just took me like 3 hours of troubleshooting and a whole lotta money for coffee and cigarettes.
Isn’t there the possibility to make it more obvious where that problem comes from? I mean if you come to think about it, it sure is obvious that you have to push your settings in order to see the refractions, but somehow it should be better pointed out.
Looking forward to some kind of solution
