Hey, I am having an issue with atmospheric fog and translucent materials. I currently have a lake in my scene. This is how it looks when I try and drag out an AF actor: [https://farm4.staticflickr.com/3885/14406970219\_f13d319e96\_o.jpg](https://farm4.staticflickr.com/3885/14406970219_f13d319e96_o.jpg) This is how it looks with just exponential height based fog: [https://farm3.staticflickr.com/2927/14590258921\_3d5d79e65f\_o.jpg](https://farm3.staticflickr.com/2927/14590258921_3d5d79e65f_o.jpg) Of course, if I don’t use the height based fog it goes back to normal. I don’t really want to do this though. The level is missing a lot without it. Am I missing something? It also occurs on the glass windows in a building that is in the scene. ---

Hi joshezzell - Take a look at this post, Daniel Wright has provided a good explanation of translucency and fog, [**here**](https://answers.unrealengine.com/questions/37922/how-do-i-make-translucent-material-to-be-affected.html) Thank You Eric Ketchum ---

Thank you Eric, but I had already read that posting. None of it actually solves the issue I am having. My translucent materials are setup correctly, the sorting problem occurs once I add atmospheric fog along with exponential height based fog. Once I do that, all of my objects with a translucent material render through the height fog. The only way to make it stop is to remove atmospheric fog. I can’t find anything that explains this. In an outdoor/open world game, these two fog types are both pretty essential. ---

Hi joshezzell - After some investigation, I can see that this is in fact a bug. I have entered it in with our engineers and will keep you informed as we progress toward a fix. UE-2974 Thank You Eric Ketchum ---

Found a temporary workaround to solve this issue. you just have to create a scene depth mask to add self illumination that uses the same overall color as your atmospheric fog. Will work at great distances up to a certain point. ![22023-atmfogbugcheat.jpg](https://d3kjluh73b9h9o.cloudfront.net/original/4X/d/5/8/d58a67989bbd4cfcd7856cc7d8bc2f3e97d238b1.jpeg) ---

It is now February 2015 (almost March) and this bug still exists. I reported it in July last year. We have a vast island landscape and one of our distant lakes renders right through the fog. It looks horrible. ---

Hey joshezzell - Unfortunately this issue is still backlogged, but a developer has been assigned to investigate a fix for it. I wish I had better news to tell you, but I have added a comment to the issue report asking for an update. As soon as I hear anything I will get back to you Thank You Eric Ketchum ---

I noticed that this is issue has been marked as resolved, I wonder if it’s really been resolved? i am still using 4.8 and i am currently being troubled by this particular bug. Sorry to ask you this again because i could not find information regarding the UE-2974 issue that you have mentioned. But i noticed this in 4.9 changelog: > Fixed missing rendering of some translucent geometry, editor/debug material had SeparateTranslucency on, which often it shouldn’t be. Was that the fix? I am still a bit reluctant to migrating my project to 4.9, but if this is actually the fix then i will definitely do the migration. Thanks, ---

I don’t think it has been fixed yet considering my team still has the problem on all our water bodies in our project, using 4.9.2. ---
