Cloak skin weight fails

taki39

Move the cloak bone to reveal the back side.

How can I prevent the back side from coming out?

Work on the skin weights on a flat version of your cloak, then copy the weights to the thick version. Both sides should have identical topology, in case that's your problem.

Thank you for your advice!

Should I skin weight a cloak that has only one side?

taki39

Skin weight was done on only one side.

I was able to improve.

Thank you very much.

But,

You can see the back side a little.

Turn on blackface culling.

If you dont want to deal with this mess you could cheat a bit have the cloak one sided and keep thickness only on the edges

If you want different color for top and bottom you could do that as shader effect

If you want to keep both sided I pretty sure that top and bottom verts dont have exact values[default transfer weights using distance as way of distribution check of there is different option like point to point ] thats why you got this issue so you have to find a way to fix that hopefully some script as manual will be nightmare

Thank you for your advice!

I tried.

I couldn't solve it.

Thank you for your advice!

I want the cloth to be the front side (Blur) and the back side (red).

The cloak was made with [extrude].

The front and back topologies match.

What do you mean?

I can't understand.

sorry.

Your material seems to be rendering both sides of the inner surface.

How did you enable blackface culling? You can't just do it on view settings. There should be an option in the surface material for "2-sided" which should be disabled. If your material doesn't have this, you need to look for one that does, or else make your own custom shader.

Also, if this is in Unity, please add a prefix to your topic title. This will help other people with Unity experience to find your topic.

This is in maya , this is what I was talking about [image below]

Will be good to post wireframe image of your model so it clear if its as Eric suggest just a rendering issue or geo collapse on it self

Is latest image of the object in binding pose or after some posing ?

I used this shader.

 I tried blackface culling.

However, the cloak penetrates.

You need to make another shader.

Thank you for your advice!

Skin weighted cloak on one side.

I used [copy skin weights] to send skin weights to the real cloak.

result

Cloak penetration has improved a bit.

The cloak is too thin and will penetrate.

The cloak penetrates after the pose.

The cloak does not penetrate during the A pose.

Try changing the copy method from "closest joint" to "one-to-one". That usually gets better results for this sort of thing.
