Great video showcasing nanite trees!

[@AaronFhd]

Thanks really appreciate it

[@AaronFhd]

Thanks for watching everyone

Which graphics card are you using in this video?

Thank you for your service to humanity.

[@AaronFhd]

👍

[@alienrenders]

How did I not know those scalability settings existed? I've been looking for ways to tweak performance for two straight days. I'll happily settle for lower quality shadows. Global illumination seems to be the other performance hit. But it makes the trees darker if you change it. Anyways, thanks for this video!

[@AaronFhd]

Yah There is a lot in this engine.

[@AlessandroSchiassi]

Great video, thanks! If you press G to go into Game Mode, you gain even more FPS.

[@AaronFhd]

Thanks for this. bigger issue me recording 1440p for the vid which hurts the fps.

[@AlessandroSchiassi]

@@AaronFhd I'm familiar! Whenever I record a gameplay video for my game I have to either record in 1440p or lose some frames... on a 3090!

[@splashmaker2]

It would be interesting to see what virtual shadow maps look like and performance compared to these cascade shadow maps.

[@AaronFhd]

This was virtual shadows maps. I didn’t switch them over.

[@juanmilanese]

Saw somewhere else that apparently WPO kills virtual shadow maps performance because it needs to refresh the cached pages (?) every frame.

[@juanmilanese]

point being, even if nanite works on translucent meshes now and accepts world position offset, which is amazing. Virtual Shadows seem to be where the performance bottleneck lies now in trees. Maybe normal shadowmaps work better? they might.

[@Roboticgladiator]

I had to disable WPO in the textures. The shadow maps were killing the FPS. I also found that the old LOD trees ran about 10fps faster than nanite for the same scene. Of course, nanite doesn't have the LOD popping problem.

[@semmert]

I think the blurring on the trees when it moves is an issue with temporal AA, not with nanites themselves.

[@AaronFhd]

Switch the objects from static to movable and it removes the blur

[@DmitryFadeiev]

Hi! Can you help me with my winter foliage issue? When I click the 'winter' button in Material Instanse I need all the leaves to dissapear but some of them turn brown and still remain. What should I do so the only bare branches remain on the trees? 😥

[@AaronFhd]

Will have to look as I haven’t tried that

[@DmitryFadeiev]

@@AaronFhd Surely everything is in one single unfortunate tick that needs to be removed or put somewhere. But where is it?

[@AaronFhd]

@@DmitryFadeiev seems there is a issue. It is in the texture and when you click winter it should remove the leaves. But it is not

[@DmitryFadeiev]

@@AaronFhd Yup. Someone posted on the Epic Games forum that this might be a 5.1 issue.

[@Supreme_Lobster]

you should be enabling "preserve area" for trees with nanite, otherwise youll see the leaves disappear as you move far away

[@AaronFhd]

kzbin.info/www/bejne/d6qyfH2sqLdmZpY yes I do that in this video. In the preview version before it was released they didn’t have it.

[@Supreme_Lobster]

@@AaronFhd oh yea just realized the vid is a month old hah

[@AaronFhd]

@@Supreme_Lobster all good thanks for watching

[@efsfsesegsgesg8775]

u can modify shadow quality and stuff with using the side panel dont know how to name it but i dont think u have to enter a command to do it or it is to set it permanently ? because with the option panel its easier

[@AaronFhd]

You would have to set this in a blueprint or a config.Ini in the project folder

[@efsfsesegsgesg8775]

@@AaronFhd to make it effective/permanent for ur project ? what the point of the side panel im talking about then it is only for the editor ? im talking about the engine scalability setting to be precise sry im not an expert

[@AaronFhd]

@@efsfsesegsgesg8775 if you set it in the editor it will stay at those settings, and will build that way aswell. If you want to change it after you build your project you will have to create a menu to change those settings

[@efsfsesegsgesg8775]

​@@AaronFhd I understand thx didnt know that. And what the diferrence with ur console command ?

[@AaronFhd]

@@efsfsesegsgesg8775 Console commands allow you to control it through the UI or blueprints, so for example in fortnite you can set each setting

[@djentlemanguitar909]

Hi nice video! I tried to do exactly the same as you did however when I enable nanite all the textures of the hornbeam trees turn to grey and never goes back to normal... I had this problem with black alders too. Any idea of what is going on?

[@AaronFhd]

Did the shaders compile?

[@djentlemanguitar909]

Yup, I waited until the end of course. The mesh is default grey, when I open the materials, they just appear to be fine. I know nanite doesn't support two sided or Masked blend mode so even when I modify the materials the mesh stays grey for ever. And when I disable nanite (exaclty the same process you're doing in the video), it magicly goes back to normal textures.... You can see my problem here (the guy has exactly the same problem I have): kzbin.info/www/bejne/fpa9dWyuoN-fjNU

[@AaronFhd]

Also are you in 5.1 preview? if you are in the project settings make sure RHI is set to Directx12 and SM6 is checked

[@djentlemanguitar909]

@@AaronFhd Ha... I'm on 5.0.3. How did you get 5.1 preview? I'm on directx 12 but I was on SM5, let me check when I switch to SM6

[@AaronFhd]

@@djentlemanguitar909 foliage does not work in 5.0.3 for nanite. To get 5.1preview in the epic launcher go to unreal engine then click the plus when it shows you the engine version in the dropdown select 5.1 Preview. which is not preview 2

[@FuckSvenskLag]

I can't even import it. UE5 hangs completely when I drag a tree into the level. Any tips? Got a pretty decent build with 24 gb ram, i7, titan x 12 gb (1000 series)

[@AaronFhd]

That is weird. Could be something in you nvidia setting that you may need to reset. Also make sure you are latest drvers

[@FuckSvenskLag]

@@AaronFhd Thanks, I'll have to try that

[@BobRoss-uq2wu]

I fixed it by opening the zoo level and waiting for it, then go back and everything works

[@MrOverDroid]

I'm facing a heavy performance drop as soon as Nanite is turned on...

[@AaronFhd]

Nanite is still heavy and you need a good card to use it. Also make sure virtual shadows are on. As Nanite takes a hit just with regular shadow maps

[@flyingroads3498]

What about colisión?

[@AaronFhd]

Collisions work just like before

[@flyingroads3498]

@@AaronFhd so no collision

[@AaronFhd]

@@flyingroads3498 they have collisions Not the best but they have

[@flyingroads3498]

@@AaronFhd yes I Will use them but as foliage. But need to add collision. I found a way to do ir but don't remember.

[@AaronFhd]

@@flyingroads3498 you can edit the simple painter model and take a look at the collisions

[@itscoldcoldwinter]

Nah this is not to much tress in real life we have more

[@AaronFhd]

True but for a game it’s a lot
