does it run well on low-end computers?

[@Albert-Freeman]

Good video my dude!

[@matty3732]

I love you, thank you so much!!! I did this effect with pivotpainter which can't be used for mobile phone, But with your method you saved my life!!!

[@UnrealCG]

Glad to hear that.

[@abeymiranda5457]

nice to see a fellow malayali making games

[@UnrealCG]

You are the second malayali that met here. Nice to meet you.

[@andrewch784]

Wow!! Very Nice bro.

[@UnrealCG]

Thanks :)

[@fl260]

Thanks man!

[@Albert-Freeman]

Recommendation: put the video in x1.25 speed

[@medmel2160]

Hi, thanks for the tutorial, very informative and well explained. How is the impact on performance? I'm thinking about using this kind of technique for a mobile game.

[@fightinfree]

awesome tutorial! I got the 1000th view!

[@3rdDimensionFox]

how would you add a delay on the grass returning to its original position? I'd like it to just pop bad up slowly so it feels more natural

[@SenEmChannel]

Help. Follow what you did and grass still not moving. I follows what you did again. Nothing happen😅

[@Kausemus]

It kinda works! For some reason my grass doesn't go to the ground level tho... and changing the Z value (blue append) up or down the grass always goes up instead of down. Any ideas why this might be? So how could I change the grass "ground level" to be lower than my characters pelvis? :D I did everything exactly as you except that I placed the Level Blueprint part straight inside my characters blueprint. Should make no difference. :o

[@UnrealCG]

I don't think it should make any difference. Try inverting the Z value.

[@ВасилийЖилкин-р1с]

Awesome!!!

[@BlackcatOverclocking]

Thank you ;( you got new sub

[@arens8293]

Do you have a video showing how to add the optimization features you mentioned at the end?

[@TheSebledingue]

Thank you very much, nice tuto. Could you explain to me how to check that my character does not touch the grass please? I would like to optimize to the maximum

[@moastafaeid6051]

But how to make grass return to its original position when we move away from it ؟!؟!؟!؟

[@SenEmChannel]

Useful video. But audio is too small. And you dont explain what going on. I have to watch 30 minutes to do what you say in 13 minutes video. And i do it blindly. So tired

[@AlienPixel]

Hey very nice tutorial. Do you think this is possible to deform the grass from a 2D texture for a Paper2D project? Let's say I'm walking on the texture and I want to displace the grass

[@UnrealCG]

Any reference video you got for that effect? from any other 2d games?

[@AlienPixel]

Hey Smth like this. kzbin.info/www/bejne/oHeQiquqgLmFpcU kzbin.info/www/bejne/fHavmHV3iNBspbc www.assetstore.unity3d.com/en/#!/content/89543

[@AlienPixel]

Maybe Ori but not sure

[@UnrealCG]

Yeah this is doable.Those grass is made with a plane mesh and depending on the players position the vertices are offsetted. Your game looks great btw.

[@CraitoiuSergiu]

Thank you very much :). Yes but I'm trying to do that with a single texture instead of a mesh so only 4 vertices. www.yardcareservicesutah.com/wp-content/uploads/Grass-back.png I'm trying to displace based on TexCoordinate but I'm missing something :(

[@Donotargue]

So as it seems this will only work on the character/player? You can not use the same parameter(s) on enemies to make them bend the grass as well? How would you be able to set it up so it works for both the Player and AI? at the same time?

[@UnrealCG]

You could also make the set the vector parameter collection in inside the ennemy AI. there by getting the location of its position.

[@Donotargue]

UnrealCG wouldn’t that make it work with 1 enemy only?

[@UnrealCG]

If you need it to work for more than one enemy you have to create many vector collection parameter and max them together in the material. Set each of it in the enemy blueprint. But I don't really recommend that, Depending on how many enemies you have it will become very expensive.

[@Donotargue]

UnrealCG so what solution do you recommend? Or is it simply not possible?

[@UnrealCG]

You certainly can't do it with just a single vector collection parameter. As the first one will reset when the new location information comes from a different enemy.There is however a solution based on render target.Watch this video it uses a similar concept. kzbin.info/www/bejne/bGjdZqhuj8h4mdk

[@OAXPxo]

Upload the project please :) and it's not very realistic the effect on grass is like too far of the character

[@marshaliftee9009]

The video is awesome. But you need to upgrade your THUMBNAILS. It is very BORING and DULL. A good thumbnail attracts people, which will increase your views, subs, likes and people's TRUST OF your SKILLs also

[@UnrealCG]

Thanks for the suggestion.I will try to improve it.

[@eyezlee1142]

Why so mean?

[@JustinLonas]

I think he is providing constructive criticism. I don't think the intent was that of malice.

[@AuxiarMolkhun]

So I'm trying to do this project myself and am running into a problem of my Material Parameter Collection being blank when I open it instead of showing the Scalar and Vector things. Any ideas on how to fix this? Because I'm at a loss and google doesn't seem to have anything for me.

[@UnrealCG]

Have you tried restarting the editor?

[@AuxiarMolkhun]

Yes and sadly no results. I honestly have no idea what it could be, whether it's the project or just something missing from the install.

[@UnrealCG]

I don't think it is due to stuff missing from install. Which version are you using?

[@AuxiarMolkhun]

The most recent version as far as I know, 4.18.3

[@UnrealCG]

I think its a bug.

[@RomixV]

What about player.start? how to apply to him?

[@UnrealCG]

For that instead of third person character. Just type in get play character. Then from in you can get the capsule location and the rest is the same.

[@RomixV]

Huge thanks!) Now it's working

[@UnrealCG]

Welcome :)

[@HuntedRedStoNe73]

@UnrealCG great video but it dosent work for me for some reason, Is there any chance you can help me?

[@HuntedRedStoNe73]

@UnrealCG it work's with the character i placed in the level, But after i press play it spawns me as another character and it dosent respond to me

[@UnrealCG]

You want it to work on two different characters?

[@HuntedRedStoNe73]

UnrealCG No, I placed the character in the level like in the video, But when i press play i spawn as a different character and the grass dosent work on me, But on the other character that just stands there

[@UnrealCG]

Ok. So type in get player character on the level blueprint then drag of from it and get world location of capsule component then connect that to the vector parameter collection instead of of thirdperson character.

[@HuntedRedStoNe73]

UnrealCG i will try that, Thanks alot for the fast reply :) Afterwards ill let you know if it worked

[@MuhammadRoychanMeliaz]

You need to buy a new microphone. Or at least try to adjust the volume. Good video overall

[@UnrealCG]

Yeah I have to get a better mic.Thanks for the suggestion.

[@苗宇-w9j]

How to make it work on multiplay ?

[@UnrealCG]

I don't really know, I never worked with multiplayer before.

[@nikolalackovic4700]

does it affect on fps ?

[@UnrealCG]

Yes, it does work in first person shooters.also it doesn't have much impact on frames-per-second. This is a very cheap effect.

[@andrewch784]

Bro! grass download link pls.

[@UnrealCG]

The grass is from the open world demo.You can download it from the learn tab of your unreal engine launcher you will also get may tree and foliage mesh with it.

[@andrewch784]

UnrealCG Thanks Dude :)

[@itsgmartin2172]

brother wtf ?? im so lost be more clear
