How To Add Custom Collision To Meshes In Unreal Engine 4/5 (Tutorial)

[@MZONE3D]

Not bad, however for something like this You can just create 3 box collisions in the static mesh editor. 2 for the walls and one for overhead.

[@dwelleroftheinternet8499]

yeah, i prefer making the collisions myself out of primitives, gets you exactly what you want with a very simple collision

[@saintmitt7123]

That’s what I was expecting him to do since he said custom.

[@chickishot8172]

Thank you for this! I knew I needed to do custom collision but didn’t know how.

Thanks a lot Matt 👍

nice one mate thanx!

I thought we were going to actually import collision meshes from a modeling application. Is that possible? I want to model my stairs as an ideal ramp and the hulls are producing artifacts.

[@Mjbrowngraphics]

Hey man, yes you can import your own Meshes from a 3rd party program, I do with some objects that require specific collision shapes, heres how: - Export the collision object as an FBX file from your modelling program into the file directory of your unreal project (content folder) - Unreal will then detect the file and ask you if you want to import it, alternatively drag and drop the FBX file into your content drawer directly - Once imported it will appear in your content drawer like any other object - Then double click the object you want to add the collision to - Tick "Use Custom Collision" then under that tick box drag and drop your custom collision mesh into the complex collision mesh slot - Change the collision setting from project default to "use complex collision as simple", it will now use your custom mesh, best of both worlds, precise collision while reducing the load on your system. One word of caution though, if your custom collision mesh has too many polygons then it will not be fully accurate and you will still get artifacts, usually in that case I break the object up into smaller separate objects with separate custom collisions. Hope this helps 🙂

i have set this two options for a rock formation i got from Quixel Bridge and tried it with waterfall template from Niagara and the water just ran through it, not on it. I even added collider tag and still...any suggestion? thanks.

[@PixelitoPC]

Thank you broo, effective and fast tutorial

[@AlehAoliege]

When the model is imported into UnrealEngine using the glb/gltf format, it cannot use prefixes such as “UCX_” to generate collision meshes for the engine. How this fix?

[@djsalis]

Great video :)

[@andystanciu1643]

Today it took me 1 hour to find a solution to my problem with collision and exactly today a video about collision... lol

[@khannichinnu5422]

Can you make a video on looting system pls🙏🙏🙏🙏

[@FedosGames]

help me please! when I build, the lighting at the level freezes by 99%. The level is not reloaded, everything is fine with the computer, this is the only level that is not processed. What could be causing this, and how can I fix it?

[@rifat.ahammed]

Thanks for this.

[@the_neutral_container]

Thanks, that was a small epiphany!

[@andrijas5515]

Bro you saved me

[@stephenvanbellinghen933]

How do you add the collision using a model made using Unreal Engine modeling tools?

[@AlbertonBeastmaster]

Easier to create in UE5 or in 3D modelling software and import in?

[@sulphurous2656]

Coming from the Source Engine, I'm used to modelling all of my collisions in 3D before importing the model if I want them to behave in a specific way. Save for some really common props like boxes, where you can get away with using the automatically generated collision meshes/bounding boxes.

[@EliteSoldier76]

What is the settings I need to implement if I want the player to collide with the meshes but I don't want the enemy AI to be able to collide with the meshes as I want the Enemy AI to be able to walk through the meshes?

[@massivetree7937]

In my own project, I'm using some static meshes for ground objects because its mainly an urban environment so using the landscape system would be overkill. Using both the auto convex collision and using complex as simple doesn't always give good results. Have any suggestions?

[@pisurky]

Hi, is there a way how to set collision for multiple object at once? Thanks

[@REE-Animation]

Can you make a video on how to do the same for a skeletal mesh? Like a car rig, how do you make a custom collision mesh for a rigged vehicle? I’ve tried for months… I got it working somehow in UE4 years ago, but I can’t figure it out in UE5 Please 🙏 (if you know of course)

[@bahrainhasnan]

You got the solution?

[@vorzky1164]

Hey, I'm quite new to UE5 and was curious if you could do a tutorial on weapon wear/rust, where you use two textures (a normal and a rust one) and gradually show one procedurally based on a value that could be assigned to a durability, or just a fixed on.

[@ShonkV]

CSGO weapon skins don't rust or wear over time , the skin makers make 5 different versions of the same skin to represent wear, like factory new , minimal wear , field tested ... All these are separate skin models or textures

[@vorzky1164]

@@ShonkV But CSGO skins are tied to a float value, which determine how worn and what group they belong in. This makes it so even if you have the same wear and skin, weapons can look different. Same with TF2, but I dont think it displays a float value.

[@ShonkV]

@@vorzky1164 yes, so what the skin makers do is, mark areas that can wear, and the float just removes those areas(textures) , suppose float is 0.2 then 2 areas from minimal wear skin is removed , if 0.1 then only 1 area is removed , so it's not like over time but are just pre defined wearing. Csgo assigns the float and according to the float , that area is removed. Nice question btw , you can use this same method to wear a skin over time Too by making the float change n runtime

[@vorzky1164]

@@ShonkV Maybe I should change my comment then. The effect Im looking for is similar, but instead of areas that are placed onto the weapons, Im looking for a procedural solution to show varying amounts of rust/wear based on durability for a survival game.

[@ShonkV]

@@vorzky1164 yes. its done in Metro exodus btw

When im enable nantie to foliage its drop fps to 12.when i close to tree

[@billionrscwm1798]

Dies hull precision number effects fps?

[@hendra_winata13]

Does "Use complex as simple" cause huge different fps?

[@MattAspland]

If you were to use it on a lot of complex meshes in your game it would yes, but for a few ones here and there, especially simple ones, it will be fine. Although, with Nanite there may be no issues, thats something interesting to look further into.

[@hendra_winata13]

@@MattAspland Is the impact feel right after we start the game or after we do something like interact with that mesh's collision? Thank you very much for the reply.
