Hi everyone, how to create glass material like cycles in eevee.
In this case, the object have thickness like a glass bottle.
Thanks.
You can’t. Cycles properly emulates refraction because it is a ray tracing engine, where light rays are simulated and change direction as they enter and get out of the glass, in a realistic way. For every pixel, it finds what parts of the scene affect it.
Eevee is a rasterization engine: for every vertex (part of the scene), it finds what pixels it corresponds to. It is much faster, but doesn’tactually emulate light. It uses tricks to have shadows, etc. In this case, refraction uses the normal of the point in the surface to deform what part is seen behind it, using information from the screen, but there is no light being deformed. The same happens for reflections.
The only way would be to add ray tracing to some parts of eevee, as real time raytracing is developed (which the recent announcements from microsoft and ATI were about).
PD: this happens with every single real time engine: UE4, Unity… refractions are one of the areas that really need ray tracing.
Thanks for the answer.
Next question (sorry about that).
How to fake it like the video below.
I notice that the glass on the table at the back does have thickness, but when creator panning around the view, the glass doesn’t show any distortion on background objects.
Thanks again.
If it doesn’t show distortion, then it is just a glossy transparent material, and thus has no refractions. As you can see, the reflection of th light help hide this, as well as the fact that the glass is not thick and is not the focus of the scene.
