First of all EXCELLENT tutorial!! I have a question though. Last night I used this method to create tire grooves in mud behind a vehicle. But after only a few minutes of driving, my framerate bottomed out. Do you know of a way to essentially "reset" the material/destroy all of the added components in the order of creation after, say, 20 seconds or so?

You could add the static mesh components to an array and then delete the oldest of array after a few seconds

Guys there is one tip for you. When you go to higher you cant erase the snow. So you must open your Virtual Texture Volume Blueprint and change the Z: 5000 or what ever you want. So it will be fixted.

Thanks a lot. Your video helped me much. But can I ask a question? I followed all of your mentions and steps, but in my engine (UE 4.27 ver), if my character jumped, there are the white planes in the air along the way it moved. How can I remove it? Should I add the nods...? I need your help :)

[@VladyVeselinov]

Isn't it expensive to spawn actor components every frame?

[@heavycoatgames]

Yes it is, that's a terrible implementation of RVT

[@VladyVeselinov]

@@heavycoatgames how would you go about it, I tried implementing something similar with an instanced static mesh but that didn't work for me.

[@MarvelMaster]

If they are small and you maybe disable ticking in the BP it might not be?

[@heavycoatgames]

@@VladyVeselinov I think that's because ISMC are processed directly on the gpu so I guess they still do not exist in the moment of the render pipeline where the RVT process is managed. Marvel Master the RP Monkey guy you mentioned has another tutorial about drawing in a persistent way over a RVT. I did many many experiments lately and my bet is that RVTs are completely not production ready. They work for the tiny amount of purposes the devs made them for and that's it, as soon as you move outside this tiny boundaries all starts being badly implemented and unstable. Atm the best way to work with snow I think is still renderTargets. Even the tutorial of the RP Monkey fella leads to a waky and not super stable system, but it's understandable since he is using tricks to achieve that. Guess we should wait for some more effort from Epic. In case you guys are interested there's a ue4 Eng group which is growing on Telegram where to ask and discuss about UE4 t.me/unrealengine_world Sorry I couldn't be of more help, I'll keep experimenting and eventually I'll do a tutorial on it if I find the proper way to set this up

[@heavycoatgames]

@@MarvelMaster PS. dimension doesn't matter much, what matters is the amount of draw calls you are creating at every single tick. If you want to go that way you should at least make the component vanish after X time, maybe fading the material before and then destroying it. Still bad practice tho :(

[@Demnus]

Wait a minute! You're creating at each game tick an object. Means there will be literally thousands of them after some time of playing. And each time you create one, you're rerendering the whole VT with all the objects rerendered to it again. So the question is what the performans will be after for example an hour of running around with that implementation?

[@MarvelMaster]

You can also despawn them by distance

@@MarvelMaster Excuse me, I'm a beginner) I did everything according to your lesson) but how to remove the trail of the player?

[@MarvelMaster]

@@glebkruglov2570 in the blueprint get a distance to play every second or so and if too far then kill

[@Demnus]

@@MarvelMaster To remove those things it's needed to be addressed. So they should be added to an array, which then should be iterated through, each second or so to check the distance. That's also seems to me as quiet expensive operation depending on number of spawned elements and might lead to hitches every time it is performed. Doesn't seems as elegant solution. Also, for me personally, the task at hand is actually to make permanent changes to the level. Like wreck the whole level to the bottom of hell. That's requires more like render target and brushes approach but with use of RVT tech because it's needed to be very high res to cover pretty huge map. I've seen a solution in another video already. But there's caviats as well...

Sure

[@pr3c3l84]

hello, would it be possible to change the shape of the snow so that it would not be so rectilinear, and also could it be done in such a way that it would be possible to draw a different texture on the ground?

[@MarvelMaster]

I think so

[@Robbe1912]

are you creating a plane every frame when the character is moving? this would certainly not be usable in a game because of the performance impact. i would also suggest explaining the reasoning behind the nodes you use, what they do exactly, since right now you are just stating your actions. to isolate the world-z in the material, you can also use a component mask, which is cheaper. i can recommend this tutorial kzbin.info/www/bejne/bGjdZqhuj8h4mdk

[@MarvelMaster]

Well the advantage of this is you can paint across tiling which usualy would need some custom code to achieve...for performance you can destroy the planes after a certain time or distance....usualy you can do all this with render targets too but I dont know which is more performant and which works on which platform. I also tried to explain a little but because I hate long tutorials in general I tried to keep it semishort...and if component mask works in that context I would need to test but sounds legit in theory

[@Cpt.Tripps]

@@MarvelMaster Do those meshes even count as draw calls? Though, provided the static mesh can be substituted with instances of a HISM, there should be virtually no performance impact. Number of instances can still be limited with oldest ones pruned.

Hi, I don't know if you're still answering questions for this video, but I've come across an issue. I'm utilizing level streaming and I have it set up so that when the level loads in a static mesh component it's supposed to appear and displace the geometry for an actor, not the player. Is there anyway I could go about displacing the geometry of the snow beneath an object before the level loads or after? Either way works for me if you know a way.

[@MarvelMaster]

Don't know what you mean

[@lancecasselli4579]

​@@MarvelMaster Well, I have an actor that has to load in on top of the snow, but it sits right from the bottom of the ground all the way up to player height and the snow doesn't displace when it loads in via level streaming. What I'm doing, in concept, is making something appear like it's de-materializing and then re-materializing into a new level. Here: kzbin.info/www/bejne/hoGqga2sp7tog68 I pretty much just wanna displace the tessellation of the snow preemptively . I might just be a nit pick, but it'd be kinda nice to do as it doesn't really look good with the non-euclidean system that a lad of mine and I got going.
