Apex Cloth Disappear after Setting Custom Time Dilation to 0.0f

I am want to pause objects by setting its CustomTimeDilation to 0.0f.

After setting this value, the mesh part with apex cloth just disappears, which is really strange.

How should I handle this problem?

Hi Andrew,

I’ll explain this using cloth map in content example.

In the level blueprint, I have things like this:

I click play, and press G, the cloth actor just disappears:


It’s been my observation that those vertices calculated by cloth get disappeared. For those vertices with weight of 0, they just work fine:


What is most strange is that if you drag quickly, those actors after they get disappeared, they just appear again!

To provide more details,

Calling function Force Cloth Next Update Teleport and Reset would make cloth appear again.
