Is there a documentation/tutorial for the 4.16 Built-in-cloth system?

[Exelcior]

Hi everyone! Thanks for giving the tools a try - I’m sorry about some of the issues you are hitting. Most of them are known or fixed in our dev branch right now but I’ll provide some info here so everyone knows what to expect soon

What Should i do If the cloth is not colliding with the Physics asset at all?

@Roxasblu;714837

Hello, I’m new to cloths, been trying .apx only a few days ago, how does the collision work for ? How do I create it? Is it to be created directly inside the Engine or through an external software like it was for .apx cloths? Anyway I’m totally loving feature!

@WideBoy;714973

The collision is handled by the Physics asset in the engine. The “tubes” that kinda represents the bones is the collision. BUT, you everytime you modify size/Rotation/location etc of these tubes, you gotha create the cloth piece over again since collision detection for the cloth is made with the pshysicsasset how it was when you created it…

Apparently is going to change some time in the future, but as of for now, you gotha create a new cloththingy everytime you make changes to the psysicsAsset.

I’ve got fixed now, the physics asset is simply referenced and the bodies are extracted when the clothing simulation is created in game instead of when the asset is created in editor.

Ah thank you, now I understand why I was changing stuff but it was still the same everytime, I think I’ll have to create one manually, as the one ue automatically created won’t let me change the capsules into cubes…

Right now only spheres and capsules will be extracted. I will hopefully get the time soon to add limited cube support. The clothing solver we are using (NvCloth) can only support 32 convex planes per simulation which is only going to net you 5 cubes. I’d advise not using convex and cube geometry for clothing and stick with spheres and capsules.

Tried tool. Some things seemed to me not convenient. When I work with a brush, do not very well see what I’m doing:

1. Typically, mesh clothing has a lot of polygons and vertices, so the squares are also very many and they visually merge with each other. The color of the mesh changes as soon as I click on the brush and begin to paint. Squares - very uncomfortable. Is it possible to make the display of values how is done in 3DS Max - through color or with lines of different lengths? The lines (maximum distance, etc.) I can see in the viewport, but not while working with the brush.
2. It is awkward that the mesh is translucent. I usually make clothes a separate mesh, so in the editor I see only part. When it is translucent, I can see the back side, the back squares merge with the front squares. It’s a sort of mixture that is hard to understand what I’m doing now with a brush. Especially uncomfortable if I work with a skirt or dress.

The clothing simulation mesh should ideally be a very coarse approximation of the actual renderable geometry as clothing simulations are expensive (especially if collision is used). If the squares at each vertex are merging for you I’d say that simulation mesh is likely too complex for the application (although obviously there’s always exceptions e.g. only one char has complex clothing).

Either way I have removed the rendering of every vertex and instead use an overlaid wireframe now, the points only draw inside the brush interactor so complex meshes should be easier to edit in future.

Either i am doing something wrong or there is some problem. When i press enable paint tools, the section changes spatial rotation from upright to laying on the ground. When i try to paint it with brush - nothing changes. No matter what strength i set it continues being white. After numerous tries and reading thread i blindly tried “gradient” method a few times (i don’t really understand how it works, previously only painted with brush in maya) and it started working very crudely in physical body window while simulating, but it still doesn’t work in game.

@jordylakiere;719666

Same as Antvg - mesh drops to the floor and no matter what I do it won’t start simulating – experimental definitely I hope to see work soon, the PhysX cloth modifier in max is giving me a headache and I can’t seem find any up to date tutorials!

was a bug that I’ve resolved in our dev branches, the root bone transform was being incorrectly applied in the editor for the editable proxy. Meshes imported with rotations displayed incorrectly but should still work when simulating.

@VikaBee;719823

it’s pink because “max distanses” = 0. when you begin to brush, the color will change

despite a lot of inconvenience, tool in UE4 is much better and clearer than the apex import from 3DS Max. From Max I always received something unpredictable.

I’m still wondering how to use the masks. no one asked a question about it in topic. Max apex-plugin has no masks. why are they here in UE4?

Masks were partially implemented as 4.16 went out. It’s essentially a level of indirection ontop of the parameters so we can have multiple versions while editing and switch between those in the clothing tool. In 4.16 they have no effect and can be safely ignored. In future releases you will use masks to target and affect parameters rather than directly painting the parameter. In the long term will allow us to add more advanced features like blending and maybe switching out masks on the fly (although that currently isn’t planned, just a possibility for the future).
