[UE4] Cloud system and Interactive Fog particles

wavewarrior

Hello everyone I'm back with a personal project involving the creation of cloud volumes using ray marching techniques and 3d volume textures in addition to Interactive Fog/ Mist Particles.
I'll post my progress here
Here's my current blockout for my final scene.

FreneticPonies

Custom raymarching or 4.16? Either way nice work, I like the swirly animation effects.

wavewarrior

What do you mean by 4.16 is there a new feature i'm not aware of ? Because I was just planning on using the raymarchheightmap function.

FreneticPonies

Raymarched volumetric rendering coming up as standard feature, no need for custom stuff. You can get it in the master branch right now and it'll be released in 4.16 official.

That being said your stuff already looks great!

Looks very cool, i'll keep an eye on it

wavewarrior

@FreneticPonies That actually sounds really nice, I'll look into it

And here is a small update, I started working on some props to fill my scene and started fiddling around with materials for the landscape.

wavewarrior

Hello everyone, here's another update. I started working on making some more props and finished setting up some things so that I could speed up my workflow, I made a blendable material that blends between bricks and plaster. I also made some decals to decorate the scene.
I've also managed to fix some performance issues on the interactive fog. 

up next is an actual door and some wooden props to put inside the doorframes.
I'll also make some more modular pieces to further fill things up.
I'll keep you guys posted.

Hi everyone, here's another update, I finished making some of the core props, but I still have to make some things to bring my scene to life.

Ok guys, here's the newest version of my scene I added a lot of stuff to change the overall shape of the alley and also added some things to make the silhouette more appealing

stilobique

Ho, i'm impressive ! Can share your technical way ? I have no idea how to make that.

Mirge

Nice one dude, some insights maybe? 

3DMad

Does it drop the frames?

wavewarrior

@stilobique I implemeted nvidia flow into a custom version of the ue4 engine 4.15
@Mirge This is a scene I'm making to show of my grad work, it being about interactive fog particles the scene itself is heavily based on the theme of assassins creed syndicate, it's an alleyway in late victorian London.
@3DMad It does drop the frames quite a bit, but I've been trying to optimize it here and there, and I can get around 54-58 fps so all in all it's pretty manageable

So here's is another update, I added some more atmospheric props and changed the scene to be more enclosed.
Also here is a small vid showcasing the scene a little:

3DMad

That's very good 54-58 fps ...looks very good. I always find a huge drop in performance on UE4  when I use particles.

Here's another small update, I've added some new props and worked some more on the lighting 
and another short video of the complete scene https://puu.sh/wlclR/6e40113b2a.mp4

Ok guys here's my final update I had a lot of fun working on this project and most certainly learned a whole lot of things. 
Here is the link to a video I made about the project : https://youtu.be/0ZkcZjyXq0w
and following is a whole load of pics

was trying to create this with regular particles, but the amount of particles i have to spawn would be overkill.
Realy wondering how you are doing this and what impact it has on performance!
