One correction for those who might care - don't bother with hooking "per instance fade amount" through the linear gradient. Just multiply it by your texture alpha and hook it to "opacity mask". In my case trying to modulate it by that gradient was cutting off part of the top of the texture, which is why my shader complexity view is so bad.

KZfaq Algorithms heard I was making grass and decided this video would be good.. it was.. Thank you!

I know how it feels to make a 20 min video and nobody watches it, but this one worth it. You literally taught me things I was searching for a very long time and couldnt find it on other 5 minutes tutorials. Thank you very much. YOU WHO STOPPED TO READ MY COMENT AND CANT AFFORD 20 MINUTES BCS URE TO LAZY, DONT LEAVE. WATCH IT.

Most underrated UE channel for sure.

I like the way you explain things instead of just showing how to do it.

Great channel! Very useful tips. Even though the video is long sitting through it wasn't hard at all.

This helped me a lot! I was wondering how I could have a whole forest with choppable trees, since UE4 can't handle over 2k empty blueprints for some reason.

You should use the project setting "masked materials in early z-pass" that will eliminate your overdraw. huge perf increase

for grass interaction u can do it using distance field ..

There seems to be a maximum culling distance for my grass, but it is way too low. The culling distance only works until about 5000, after that if I keep increasing it, it has no effect. I don't need good fps, btw.

Hey guys maybe somebody of you can help me? I tried to understand why when I paint with the foliage tool the performance on my pc really went down so when I tested the foliage tool with RenderDoc and the GPU visualizer I saw that when I painted a static mesh with the foliage tool it took a double amount of time to render the object than just placing the object without the foliage tool (same object same size same position of the camera) so anyone here knows if it’s just the downside of the foliage tool or it might be fixed?

Thanks a lot for this viideo men.

I notice that grass Max culling is to set how far the grass will be rendered from the camera, But I don't know what the min do. I'm working on some archviz project and I need to make a dense sort grass for the garden, So I make two kind of grass model, The high detail for closer to camera and for low detail grass for longer distance from the camera, Now I need to set the High detail grass culling from camera to about 10 meter and ways from camera, and start to show low detail grass after that 10 meters to as far as the landscapes goes. how do I set the low detail grass to only rendered after 10 meters from the camera and beyond. Coz right now below 10 meters, i have two grass, high and low detail..and If i look closely, i can see the lower detail of the grass which is running the scene.

I think its less expensive to set material parameter per tick, against then to check/compute all possible reasons not to.

the fade thing in the grass gives you about 100 less FPS i dont recommand doing it , we do culling for more performance but when you do this you lose alot of performance

I really wish you were slower about this smooth fade node and how it actually works, it's something that not a single grass tutorial shows, and going so fast I can barely learn what's all about and how to use it...

Can u do a separate video showing how to go about that part where you were talking bout grass that could stay deformed for a certain amount of time then reverting back to its original transform.Maybe show examples

hello im wondering if anyone can help me , my foliage looks inconsistent, it looks darker further away , ive set the color to blend with the landscape textures , it looks good until im further away from it , it darkens n no longer blending I have no idea why, I cant find anything about it

Doesn't work for me at the part of deleting instances. using the first setup you show with setting the visibility to not visible and hiding all the grass instances at once works. But if i try to delete one of the grass instances with the remove instance node and using the other body index nothing happens.

Hey Matt, I'm having an issue with the grass cut system. When I apply the collision for a capsule collider in my "sword", the grass detects it but it wont get deleted; but when I do the same with the capsule component, it works perfectly. I recorded this video showing the issue:
