The Ephere physics system has just been updated. Info at: https://ephere.com/plugins/autodesk/max/lucid/ Changelog for just this version: New: Torn cloth preserves material ID's Fixed: Lucid hair simulation is not recorded when using Strand Groups Fixed: Changing the Strand Group causes a crash when re-recording hair simulation Fixed: When tearing is on, recording (baking) cloth object drops recorded frames. Internal improvements The main thing in the last couple of releases, is the support of either Cuda or DirectX for simulation. This should make many people happy, except that I'm not one of them. The DirectX support needs at least DX11. I have DX9. And that's why you get no nice simulations from me.
