Architectural glass

[jrlc7510]

Hi,

I've been working with Octane since the beta version of the first release. But there's still something wrong with the glass and the architectural rendering if I compare with Vray and Maxwell Render (I've worked with before).
There are a too much refractions and shadow refractions of the same object, that's making a very strange picture for a contemporary architectural visualisation.
Could you build a special matérial for this (not a "bricolage" from a specular, or glossy material), like the AGS material in Maxwell Render for example?
Or maybe I've missed something on the way to work with?

Cordialement.

I notice that term in various places ... like our Material Live Lib. Could some kind soul explain to em what "architectural glass" is with regards to rendering? Is it a cheap glass soluetion, that is not real glass, but renders fast? Or something weird that can work without having a depth (i.e. just a 2D surface) or so? I'm confused about this term.

Yes Voon, it's for surface with no thickness.

from the maxwellrender doc :
Architectural Glass Solution (AGS) is a "sort" of glass material, very useful for window panes on architectural projects, where you don't need the time consuming properties of actual dielectric glass (refraction and caustics) but you want transparency and reflection.
This "trick" is created by using a single mirror material (white Refl0, high Nd around 20 or 30, and low Roughness around 0) but setting the opacity of that only layer to a low value, around 15-25%. This reduces the visibility of that material although presenting reflections, but reducing dramatically the render times as caustics and refraction are not calculated.

Salut Jrlc ,
did you try in Octane to do the exact same trick than Maxwell AGS ? it mostly react the same, this is just a default glossy material with ior at 1(for true mirror), opacity at 0.2 and "alpha shadow" enable in the kernel.
But I don't recommend to use this, alpha shadow option slow down octane, better to model a very thin thickness and use a true glass material with more caustic blur, octane is pretty quick to render thin refractive object, but not so good to deal with semi opacity.

I see, thanks. I only wodnered, because a lot of architectural stuff is inside rooms ... and I assumed you need real glass with thickness there to get something proper, with sunlight coming in from outside? I'm a bit confused when it comes to glass I have to admit.

I wonder if we could have a thin glass solution like corona
