Revit Frosted Glass Transparency

I have a light fixture with an inner tube that is self-illuminating, which will be my light source. Around that I have a glass enclosure that I want to be 50% transparent and 50% translucent and white (frosted). However, I run into issues at anything over 5% transparency. Once I assign the outer glass tube to anything greater than 5% transparency, the frosted effect disappears. See images. This problem also occurs in interior glass that is perpendicular to where most of the sunlight is coming from.

Am I missing something in my settings or is this a bug? I am running Revit 2018 and Enscape 2.1.

Still seems to be the issue in version 2.2.3.4 with Revit 2019 (Win10;Nvidia M1000M;drivers up to date)
Does anyone else bumped into this problem?
Is there any workaround for frosted glass?

Yes, this seems to still be an issue when trying to use the Revit transparency settings. However, there might be a workaround that satisfies your needs. From researching and testing I have found out a way to somewhat get a frosted effect by using the “roughness” setting in Revit. The more you increase the roughness, the more it becomes frosted like. Hope this helps.

running into the exact same issue; any material with a transparency setting of 6 and above becomes completely transparent, whereas anything below is completely opaque (see attached images). doesn’t appear to be any in-between. would be great to get this one fixed as we use semi-transparent massing quite a bit…

gave the frosted method a shot, but unfortunately it really doesn’t work either. definitely appears differently than a custom generated transparent material, but falls far short of appearing semi-transparent/frosted.

You should be able to get frosted glass by using similar settings to these

This is the result

Jonathan, thanks for your input. I have tested different settings, one using your settings. See the attached results for discussion.

Setting 01 is a rough glass set at 1.00.

Setting 02 is Jonathan settings with a transparency of 6%.

Setting 03 is the same as 02 but with a transparency of 25%.

Also, there seems to be an issue when there is no natural light and only artificial light is used. It seems to change the color appearance of the “frosted” glass.

Many thanks to Jonathan and boops for the responses. I tried Jonathan’s recommended settings on the same massing I showed in the previous images, but with no luck. Objects and linework behind the “frosted” mass are still clearly visible, not diffused like they should read. I’ve also attached my Enscape settings for reference.

@charlie_payne @boops My shared settings are only a workaround and there still are some limitations.

Glass currently

  • does not cast shadows,
  • colored glass does not change the color of the light flushing through and
  • effects in the glass, e.g decals, translucency, frosted glass are affected by the current lighting and the Render Quality (as the light calculation differs)

It is on our agenda for still renderings as it is a needed real-time optimization for now.

Ahh, bummer for us but at least we know it’s being worked on. In my mind, the biggest reason the “frosted” material still reads as transparent is because the linework behind the object is not diffused. Thanks for the help Jonathan!

I have discovered another method for frosted transparency effect that I think works okay. I have not tested this method at a larger scale.

Use decals with a white or colored base image and a gray cutout image. Then place the decal on clear glass and scale to fill the entire glass panel. If you change the gray cutout image to be darker or lighter you will get different transparency levels. I was even able to achieve a gradient. This method would be a tedious if you have a lot of glass, but it might achieve the effect you are looking for.

@boops I tried transparency at Rhino too, but it cause a noisy pattern. Did you have seen it? It’s on your example too. (I still hope to get a full working transparency. It looks like there is no way to archive a basic milk glass effect.)

Thank you all, I have added your remarks to our internal discussion for the developers.

Any development on this? I still can’t achieve a true Frosted Milky glass with translucency in Enscape Revit.

Hi @neutralmotive , I’m afraid so far there haven’t been any additions to the Revit material editor, except for the ones listed in this knowledgebase article. I have added your request as vote to our feature wish list, however. Thank you for your feedback, and welcome to the forums!

Sooo 3 years later… what is the solution now?

I think frosted transparent glass looks quite good in Revit.


Perhaps you can also briefly get into a bit further detail after this time regarding what is missing to you when it comes to the current frosted glass implementation?

And how was this done? Can you share maps or settings? Thank you
