Ragdoll

Cascadeur now supports ragdoll physics. Characters can realistically react to collisions with other objects or characters.
Ragdoll can be enabled on the Physics Settings panel, under the Ragdoll tab:

Improved Secondary Motion

Now the simulation produces more life-like results.

Also, Secondary Motion now takes into account a character's collisions with other objects.

LiveLink for Unreal Engine

Cascadeur can now work in conjunction with Unreal Engine. Any change made in one software is immediately reflected in the other.
To access this feature, turn on the Live Link option in the Synchronization menu:
