Subject: Shader Ops "Fake Fresnel" - Cannot Get Right Effect


craftycurate ( ) posted Thu, 20 July 2006 at 12:29 PM · edited Wed, 06 May 2026 at 5:26 PM

Is anyone using the Fake Fresnel shader from the "Shader Ops" addin (Digital Carvers Guild) with Carrara 5?

Have downloaded the demo and followed the instructions exactly, but I cannot get the effect I expect, which is as follows (click here):

Following the demo, all I can come up with is something like the following:

The demo only allows a Fake Fresnel parameter of 33.33 value.

Thanks
Richard

Contact Eric by E-mail (support@digitalcarversguild.com) , his support for the trial versions is very good.

I'm sorry, Fake Fresnel always returns black in the demo. It was one of the ones at the time I couldn't figure out a way to preview the effect without giving it away.
