Bullet v3.0

Maya comes with both Bullet versions 2.8.2 and 3.0 pre-installed, but uses 2.8.2. as the default.

If you want to use Bullet V3.0 instead, you will have to set an environment variable. For more information, see Directly modify the settings files

Note: We recommend using Bullet v2.8.2, as v3.0 has limitations. See Bullet Known Limitations.

.
