Hi there,
First of all, I am really stoked with this new system! I appreciate the guts you guys have to do such a drastic overhaul of this fundamental part of Unreal.
I’m trying to get a basic glass shader to work on a personal project and i’m using Strata to get acquainted with the new workflow. I hooked up the shader using “Translucent - Colored Transmittance” and using “Surface Forward Shading”
In the preview the shader looks good, but in my scene there is no reflection whatsoever. I do only have dynamic area lights and no sky setup. So I hope this is not the issue. You can see there is lumen scene and reflection data:
Also Whenever I enable refraction with a relatively normal index of 1.5 the refraction goes all over the place:
I manage to fix most of this refraction by using a fresnel and a lerp to blend between a value of 1 and 1.1
And I get a pretty decent looking result out of this:
But I am not a 100% sure if this should be default refraction behavior. I do like the control of refraction by using a fresnel. But I am just wondering if this is going to be the implementation of refraction within Strata.
Anyway, I hope to get some info on what is going on here. Is it because the Strata system is still in early stages of production or maybe just that Forward shading is not supporting reflections from Lumen and area lights?
Cheers
Laurens
