You should make a 2020 version. Most of that blender nonsense has been put to pasture ;)

I am not able to get cloth to do anything at all either. I am going to try installing an old engine version to see if it's a bug in the current version.

Sorry for late reply, but if you haven't fixed it yet try this: You'll want to have the character as a single mesh, with the cloth in its own material slot. To do this, get the character and cloth as separate objects in blender. Assign them materials (your character may already have materials in blender). The important thing is that the cloth material has a unique name. Then merge the cloth back onto the character and export! Hopefully this helps.

JulSalt go back to about 5:20 in the video. You need to create clothing data first which is done by right clicking the mesh in editor and selecting create clothing data from selection. After that you'll need to right click again and apply that clothing data you've created to you cloth object. It should recognize you have one at that point. If it still isn't showing an asset in the cloth menu, try clicking import apex file and then hitting cancel, sometimes unreal engine is buggy about recognizing your applied data but cancelling the import for some reason can make it show up. Let me know if this helps!

Certain Things Studios Thank you! I don't know how I missed that, it works perfectly now :) and by the way: thanks for the video, I've been trying to get all of this to work for hours 😂

JulSalt No problem! We're glad you found it helpful. We spent about 9 hours trying to figure out why it was clipping to figure out that the paint value slider can go above 100 so we can understand your pain. Feel free to follow us if you're interested in game development! We put up videos every once in a while of what we're doing and the parts of unreal that aren't really self explanatory! Hopefully we'll get some stuff about particle systems up soon and some other art based applications of unreal.

I am thinking maybe not do whole shirt as cloth but only the "loose" parts like bagginess around waist and under the arms with sleeves. Now … what about hot swaps though? That might be a problem. Maybe use anim notify to put cloth back to default before hot swapping mesh out? So you don't see a jump ...

Precisely, simulating an entire shirt is highly unnecessary. Especially if you're designing for a game, your character is going to be on screen 100% of the time which means it should be optimized as much as possible. General rule is you don't want to simulate anything you don't have to! Depending on what kind of shirt and what material and how tight it is you might consider a shirt not needing to be simulated at all, whereas a large hoody, dress, or baggy clothing tends to warrant the need for simulation! How much you simulate and what you do depends largely on your design and what you're actually using it for. Do you have something specific in mind?

Make sure your "strength" value, under the brush section, is at 100%.
