I hope that it’s alright that I ask for some help here, since I could not find much on the internet that explained what I needed.
Basically, I need to create a post-processing sandstorm effect. I was planning on using a fog post processing effect as a base/inspiration and then build off of that.
The ideal effect I am looking for will be like the fog slowly creeping in from outside of a square that can be manually set, so the fog will slowly envelop the entire level.
The effect has to look 3d and it has to be used on a top-down camera, since I am making a twin-stick shooter.
I started with UE5 a couple weeks back and have some experience with C++, though not enough to understand what is going on with the guide I linked below, or how to make the post processing thing work using it.
I did find a helpful guide: Fog for Top-Down Games | rasie1's blog
However, I do not understand how to use any of it and the post is quite old and I am afraid I will not get a response in time.
Yes it has to be post processing. I did see some videos about sandstorms that aren’t post processing, but it really does have to be post processing, which is why I ended up asking for help rather than use a video like the one you suggested. Still appreciate the attempt though
I could give it a shot, I just hope it would also work from a top-down perspective.
If this ends up solving the issue, I will mark this post as answered, if not, I will update this post.
Thank you very much
Well it is for a project for school. Basically, we had to choose a research topic, and due to my team’s desert theme, I thought I’d choose the Post Processing Fog and turn it into a sandstorm (this was before I understood what post processing actually does) and the lecturer thought it would be a challenging yet good idea.
After doing some research on it, I found that it was much more difficult to do than I expected.
I have spent quite a lot of hours researching on how to do it, but hadn’t found anything and due to time constraints since I have lots more to work on for the game itself, I thought I’d ask in these forums.
I am really glad that you were able to help this much though, I will implement your recommendation as soon as I can!
That’s amazing, thank you so much.
I will just set the post you made as the answer to my question, since I do think it is plenty for me to work with to turn it into a sandstorm.
I will try my hardest to get this to work the way I want it to, and once it does work I will upload the result here.
After watching the videos you sent and trying some stuff myself, I ended up with the effect shown in the little Gif I sent.
I got this through the UV stuff from the video you sent combined with an effect from a video I found:
However, for the purpose of the game, this just wasn’t really 3D enough, since it is supposed to obscure the enemies like a storm would.
I will just try to study and use the site I sent in the original post since it has the best effect possible I could find while still being a post processing effect: Fog for Top-Down Games | rasie1's blog
I will try to understand it and recreate it while modifying it to be more of a sandstorm.
If I manage to make anything with this, I will be sure to update this post
