Glass rendering problem

[solvejarvinen]

Hello Friends!

I have big problem: i have excellent glass material for Vray 3ds max. In that visualisation you can see that the glass material (right side) is almost photorealistic (maybe too thick).

I have the same tex applied in my model, but this is exterior visualisation and it renders totally green with some translucency and reflection. I have no idea what causes this effect: lightning or geometry. The fog multiplier in glass mat. is 0.05 and color is very very pale green- almost white. The two-sided option is on. Help me please

Have you tried chamfering the end of the panel.

[solvejarvinen]

no, but in the example render i have this glass planels from box without chamfering and it is rendered properly.

Are you modelling to the correct scale? Check your units.

 

The fog parameter is dependant on thickness, so a 2mm thin bit of glass will look completely different to a 20mm thick bit of glass.

I must check this because I imported model in .3ds format from rhino and I'm not sure if units were rescaled properly.

[Corey Beaulieu]

0.05 is actually quite high for glass close up. Try 0.005.

The glass mat. in the pic i posted before has fog param. 0.05 and it renders perfect. Maybe it depends on light: in bathroom render i used vray lights and in exterior rendering i use HDRI and Vray light maps.

check with your gamma setting materials option

[solvejarvinen]

I checked all settings: mat. settings, gamma, global illumination... I don't understand why I have good glass render in first render and then green material in exterior scene. I'm using evermotion archexteriors so the settings must be good.

Problem solved but I have no idea how I drew box 2cm width in archexterior environment and- e voila- glass is glass. Eh, V-ray....

More like "Eh, Rhino" or "Eh, .3ds". Vray materials usually works best when geometry is modeled in a way that makes sense, and usually when importing architecture/geometry (i have to import .3ds from Archicad all the time) the geometry is not logically structured/really weird. For example when importing from Archicad through a .3ds format, even though you created a solid box with one material on it, it comes in as one object but with all the quads "loose"/the edges split, so it is not a closed volume. Drives me mad most of the time.
