UE5 - How to Cut a Hole into Anything (Unreal Engine 5) 

I appreciate your feedback. Make sure to check out my other videos too :3

@@kibibytecompany how to make it a door through which you can pass?

Tick Use Complex As Simple Collision in your mesh if you have issues.

Yeah gotta enable modelling plugin to have the tab

where is collision complexity?

oh I found it

If you follow the whole tutorial you won’t have any problems regarding having a hole in every wall

@@kibibytecompany Granted, though you don't have the hole in every wall problem, you still can't go through the hole you've created; which is the whole point of a door.

You can though? You made a mistake or have a too small hole then.

@@kibibytecompany I followed your tutorial to the letter, same with every other tutorial I've tried. I don't understand what's going wrong, no matter how I make the hole or how large it is, the collision is still very much up.

That doesn’t make any sense. It shouldn’t be like that. Try ticking “Use complex collision” in your mesh

Yes it does. Maybe they changed the layout a bit or something but it does exist

@@kibibytecompany I found it! Had to re-enable it in the settings. Weird. Thanks for this video!!!

What do you mean with “length of booleans”?

@@kibibytecompany the length of the solid. For example make a larger window. Is it possible to modify parameters after clicking the button “accept”?

So you want to keep the hole as it Is but want to resize the object. I don’t think that is possible as far as I am concerned.

@@kibibytecompany I would like to modify the lenght of the hole (window) and keep the object as it is (the wall). I found a video where it explain a procedural step to do it. not the easiest way, but possible 😅

Here’s the link for an interactive boolean ☺️ ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-L4vGmIw0PD4.html

If you have a separate mesh then sure

@@kibibytecompany it worked to cut a visual hole but the collision was still there. I’m still trying to figure it out.

There is nothing to figure out. You basically have 2 meshes. One is the visual one and the other one is for the collision. As I can imagine that you are relatively new, enabled complex collision for the mesh and you are good to go. 👍

Not exactly understanding what the problem is. You can join my discord and explain it there with screenshots if you want.

Just use a 3D program at that point.

As far as I am concerned you can’t set the exact position nor the rotation of the polycut. However, here are some tipps: Change your mouse settings or zoom very near to the polycut.

As I oversaw that you just want to rotate it 90 degrees, here is it for beginners: On the top right of your viewport you can actually set in which Intervalls you want to rotate something

@@kibibytecompany It works, thankyou 👍

Yea you can. There is another modifier you can use for exactly that. I am not sure how it’s exactly called but it can definitely be found in the same editor window

I think that's the case when the mesh has nanite enabled. Then it doesn't work.

@@kibibytecompany ive managed to get the menu but i need to change the height, however when i choose either width or height it changes only the width

That seems extremely weird and never happened me before

@@kibibytecompany is there anyway you think i could fix it?

We first need to find the exact source of the problem. Do you have the same issue with the same mesh in other projects?

You are not allowed to modify editor meshes. Try to import your own ones and modify them

Of course this is possible. Try to play around with other modifiers and you will get what you want

You need to follow the whole tutorial and not just the one part.

Tell me you only skipped to the „important“ part without telling me you only skipped to the „important“ part. Go watch the full video mate ;)

You are probably in the wrong section. You need to select it on the left

You need to select the object you want to edit.

@@kibibytecompany Sorry, I have selected the wall but for some reason It's the only wall that doesan't allow me to mold. Im using the 'vr room' template for the game im making.

Seems like a weird issue. I can imagine the tool not to work with nanite. Does your mesh use nanite ?

@@kibibytecompany nah it doesant

I honestly don’t know what could potentially cause this issue. You are using a static mesh, right? If so, try to reimport it.

Please watch the whole video. In this video I show, that you need to duplicate the wall asset before cutting a whole as this changes the whole asset instead of just a single instance. You can restore the data by clicking reimport on the asset.

@@kibibytecompany thanks!

I honestly don’t know. I think not but there should be plugins available to handle that.

@@kibibytecompany i already figured it out. Just take a door, scale a box to the size, and make it subtractive. (I’m in ue4 because of the hello neighbor mod kit)

You cannot modify built in engine assets!

@@kibibytecompany yeah i fixed it don't worry

I showed it in the video

Did you find the fix? cause in the video it shows how to duplicate it first before cutting to prevent but doesn't go over how to fix when completed? I am in same boat I cut holes in my starter walls and now I need a regular wall lol

You can reimport the base file by right clicking on the wall and hit on reimport

@@kibibytecompany the video is quite long and not concise enough.

If 7 minutes is quite long for you then really game developing isn't for you.

Yes!

You should see how long it is to make a single house

You cannot modify engine assets

@@kibibytecompany yes

That’s a little bit more complicated but especially for me very easy as my whole unfinished game is based around similar mechanics. I can do a video if I have time.

@@kibibytecompany yeah would be nice. I know there are some ways with material or with procedural meshes but it's all quite hard to do. In my case I need to be able to place windows into walls which also behave like windows (actually geting light throught) - so not super interesting stuff ;) war game sounds better

In that case I actually wouldn’t use procedural meshes as they are very heavy on performance. I would try using materials but I can’t really help you there.

@@realadnoh have you found a solution ? I have exactly the same thing to do :)

I know an exact solution but it’s very performance heavy. You can try using materials though or some other stuff like the chaos physics maybe. You could also just replace the mesh with a mesh that has a hole.

I think this is pretty easy to be honest. Never used HAMMER though.

@@kibibytecompany in hammer you could just make a wall and use it to cut through anything. So you could use a square to cut a hole in the wall for example. Also you could use a hollow button, to make a room out of a simple square box. It was just so much user friendly and easy to learn. UE has been pretty difficult to learn, even simple stuff. Also, and this is probably the feature I miss the most - in hammer you could have 4 views simultaneously, like top/bottom etc while in UE it seems like it's not possible? Like you can only have one view at at time and gotta constantly switch back and forth?

You can actually have multiple views by going to the top menu and selecting Window -> Viewports and adding up to 4 different viewports. Maybe I find Unreal Engine to be easy because I have like 7 years of experience. I wish you a better time with the engine in the feature.

@@kibibytecompany oh hmm I just casually started learning UE. I will definitely try the views trick. I might be biased simply because I used to use hammer for many years, but I only built maps for counter strike. It was very user friendly to learn basics in my opinion

@@kibibytecompany Hammer editor is almost 25 years old but still has a lot faster and intuitive workflow.its still the fastest level editor in my opinion.
