DCC PhysX plug-ins were updated to version 2.71

with 2 comments

Along with APEX 1.1 release, NVIDIA has prepared new 2.71 version of PhysX plug-ins for 3ds Max (2009-2012) and Maya (2009-2012).

Update: 2.72 plug-ins available

2.71 PhysX Plug-in for 3ds Max – Release Notes:

  • General: Fix a HW check issue for old driver causing crash for some users.
  • General: Saving file at the end of a simulation will capture transform all objects in scene.
  • General: Sprinting improvement for 3rd party plugins utilizing this plugin.
  • General: Exporter locale issue. Force to keep as period instead of comma.
  • General: Removed unused materials and shapes in exported XML files.
  • General: Fix the crash with previewer, waving flag sample.
  • General: Upgrade 3.x mode to use PhysX SDK 3.1.1
  • General: Minor toolbar tweaks.
  • General: Prevent some convex hull failure cases.
  • General: Increase contact buffer for PhysX 3.x.
  • General: Fix the bug that when in the middle baking, it restarts from time start. The reason is that Max does occasional preSave event and we prefer to rewind before saving.
  • Rigid Body: Fix button based initial motion calculation.

NVIDIA APEX 1.1 is available, GPU Rigid Bodies feature included

with 14 comments

NVIDIA has released APEX SDK 1.1 (Build 112), next version of NVIDIA APEX – scalable dynamics framework, oriented on complex physical simulations.

Update: APEX 1.2 is available

In comparison to APEX 1.0 Beta, new version includes many bugfixes, several additions to underlying framework and various new features, like ability to calculate rigid body physics on GPU.

APEX 1.1 contains only Destruction and Clothing modules, and is still based on PhysX SDK 2.8.4.6 – first version with PhysX 3 support is going to be APEX 1.2 (that is supposed to be released in a few months).

We must also note that APEX 1.1 requires corresponding authoring tools – PhysXLab 1.1 and 2.71 DCC plug-ins.

NVIDIA APEX SDK 1.1 is available for download at Developer Support Center.

If you are experiencing trouble with registration of PhysX Developer account, please refer to our registration guide.

Release Notes:

APEX DESTRUCTION 1.1

New Features

  • GPU Rigid Bodies: the NxModuleDestructible has settings to enable calculation of Rigid Body physics on GPU.

Highly anticipated feature. While using same assets and same settings, GPU Rigid Bodies are showing significantly higher performance – 70 fps for 5000+ rigid body chunks on single GTX 580 vs 10 fps on Core i7 2600K.

One-way interaction with dynamic CPU actors is also supported (via transfer of momentum). GPU accelerated rigid body physics requires NVIDIA driver 270.81 or later, PhysX 2.8.4 RC6 or later and a CUDA capable GPU.
