How to adjust frosted glass?

Hi all,

I’m looking at creating a Kalwall material, but am having no luck. It’s a highly translucent, but not particularly see-through material (Google Images). If I were doing this in VRay I’d use either refractive glossiness &/or subsurface scattering - but I’m not, I’m doing it in enscape and really struggling with it.

I thought that using Frosted Glass would be a good idea, but it doesn’t seem to blur the objects behind the glass (or if it does; not enough). Is there a way to adjust how strong the frosted glass effect is? Or a better way of achieving this?

Many thanks,

Chris

Hi @Macker202

the blur effect is easily achievable by raising the roughness of the frosted glass material:

Hope that helps! :slight_smile:

@Macker202 In the past I found that the blur effect depends on the scene depth, maybe it helps to place an object far away at the background of scene. But I’m not sure, since did it some months before the last time. Also adding a noise bump map can help to increase the blur, which is some times not strong enough. But this workaround can cause some noise.

For the Frosted-Glass button to work, reflection/roughness value should be high (50%-100%).

Increasing the refractive index value sometimes also helps.

For stronger effect, add some rough texture image to the bump map.

Frosted glass used to render better in older versions from my experience. I reported an issue last week about having specular turned up in order to get reflections on the glass. I think frosted glazing in Enscape needs some work IMO.

That’s still the case, the distance from glass pixel to respective background steers the diffusion intensity.

That is true and we are aware of this shortcoming. We will improve the transparent object accuracy in the future.

In the past I got the effect, that an additional placed object somewhere at the scene far in the background helped to get more blur. But I tested it now and this behavior isn’t there anymore.

Here an example - this is the max possible frost effect. The man is approx. 40 cm behind the glass. More blur could be really useful.

yes absolutely!!!

Ok that’s possible, we will check that.

wonderful!

I don’t think the above works! I had to make frosted glass by starting with foliage material and added texture and play with transparency.

Uuuh don’t do that @Lapx . The above works, just make sure your material (Generic material type) is transparent (set to Transmittance), set the opacity to a low value, enable Frosted Glass and set Roughness to a medium level. Doing so, I achieve exactly the result as depicted above. If this doesn’t work for you, can you share an example of what it looks like on your end?

Thanks Kaj for your response but it is no longer working for me. It use to work several versions ago about 2 years ago. Now I can not get the white milky transparent look that I am trying to achieve. Image 52 is closer to what I’m trying to achieve and that’s by making it a foliage material.



…something like this would be ideal!

Thanks for the example! Can you try more roughness? around 50%?

with roughness at 53, still no luck

Starting with self luminance material was the closes I can get to the desired result

is this any good?

this is png image for manifestation with transparency and bump from a fabric to give the light dispersing effect

Steve that looks fantastic! let me try on my machine and I’ll get back to you. Thanks!

Would you have a problem sharing the png file?
