Topic: Frosted Glass Material

[lbourdo]

Hello there,

Looking at the forums I can't seem to find a good solution/tutorial for "Faking" frosted glass.  I have a light fixture that has white lens and want frosted glass as that lense.

Can anyone please direct me as to how to do this?  I'm new at lumion and can't get it to look right.

Thanks,
Lorne

I think there might be one or two workarounds by users to affect glass, but there is no specific material that is an exact frosted glass look.  The topics are in the licensed/commercial section of the forum, but maybe a member will be able to help.

Otherwise will see what can track down and post.

What version of Lumion are you using?

[lbourdo]

Thanks.  I'm in Lumion 4.0.4 Pro.  But in the Trial Version we are about to buy the limted full version.   But will do so after I can figure out if I can get a workaround for frosted glass.

Here's the only links I found in a Search for Frosted Glass:

1.  Lumion Glass
2.  Translucent Glass
3.  Mirror surface? Frosted glass?.

There are some on translucent glass but in the Commercial Section of the forum.

There is the possible of creating a texture of rough pixels, then apply that texture to the light fixture in the modeller (3D modelling application).  After importing, set the light fixture to Custom --> Glass Material, then increase the Texture Influence slider value to max or nearly max.  That adds pixels from the texture to the resulting render of the model and may work for you.  Note: Transparency needs to be less than 1 in order for the added pixels to be seen.  (not tested)

Forgive me but what do you mean by "modeller"?  Just the standard working area in Lumion?  Or is there an additional part of the program where you can model components such as light fixtures?  Perhaps I'm reading into this a bit to much. 

Also, by texture of rough pixels what do you mean?  Just an image in photoshop with a pixelation of white pixels?  Like the one attached?

My trial is now up but we plan to buy it.  So hopefully I can get this looking right.

I'm sure I'll have more questions as I try to implement this material in the light fixtures.  Basically I want light to shine through them and I was having a hard time showing that appropriately.

Thanks,
Lorne

He meant in Sketchup, Revit, 3DS Max... whatever modeling software you use, apply the texture in there before importing the model into Lumion.

Hi Lorne

Yes, as Jared replied, have edited my post to be more specific.

Also, by texture of rough pixels what do you mean?  Just an image in photoshop with a pixelation of white pixels?  Like the one attached?

Yes.

Is either of the two images attached sort of what you are after.  I know it's not exactly frosted glass, but the whitish glow sort of thing?

[lbourdo]

Hey Peterm,

Yes the glow is what I'm after, however I need them to cast shadows and light on surrounding materials.  I know emisive setting doesn't throw that light onto other items right? 

Did you add a light source in the center of that material and added emissive to it to get the light to shine around it?

Thanks,
Lorne

Yes, just add a light from the Library --> Lights and Special Objects.

Place where needed, note absolute accuracy of light positioning is (rarely) required.  In some cases though it needs to be brought below certain lamp mesh parts to avoid unwanted shadows.

Lights cast the lit area and of course shadows.  Note they do not cast volumetric lit areas (as if inside something else) and that's where use of a little Emissive helps.
