3ds Max 2012 announced officially

with 3 comments

Autodesk has officially announced 3ds Max 2012 and 3ds Max Design 2012 – 3D modeling, animation, rendering, and compositing packages.

New set of 3ds Max products introduces first module of unified MassFX simulation system – mRigids rigid body dynamics.

Update: 3ds Max 2012 released – MassFX system overview

With mRigids, you can leverage the multi-threaded NVIDIA® PhysX® engine to create compelling, dynamic rigid-body simulations directly in the 3ds Max viewport. mRigids supports static, dynamic, and kinematic rigid bodies (the latter for rag doll simulations), and a number of constraints: Rigid, Slide, Hinge, Twist, Universal, Ball & Socket, and Gear.

MassFX system is based on PhysX plug-in for 3ds Max, and will replace existing Reactor physics engine.

We’ve already reviewed some sneak-peek videos of MassFX and spotted certain vital features – convex decomposition ans substeps control.

In addition, new Maya 2012 is also including PhysX plug-in as part of standart package.

New Simulation Options — Incorporates the multithreaded NVIDIA PhysX engine for static, dynamic and kinematic rigid-body simulations directly in the Maya viewport. The PhysX plug-in also includes kinematic ragdoll simulations and APEX Clothing.

New MassFX video showcases convex decomposition feature

with one comment

Autodesk has released another sneak-peek video of MassFX – PhysX SDK (and PhysX plug-in) based physics simulation system for XBR (namely 3ds Max 2012).

Previous video has showed us that substeps control will be included, and this one reveals another interesting feature – composite physical mesh type (previously spotted only in internal versions of PhysX plug-in).

In this case, user will be able to decompose concave mesh (not supported by PhysX SDK natively) into convex pieces, using built-in algorithm, and simulate it as one physical object.

Now, with both convex decomposition and substeps control features MassFX may show itself as pretty effective tool, at least for rigid body simulations.

PhysX based simulation system in Autodesk XBR will be called MassFX

with one comment

We already mentioned plans of Autodesk to replace Reactor (using Havok) physics engine in next versions of 3ds Max with a new and probably better one, based on PhysX SDK.

Update: New MassFX sneak-peek video

Recently released “sneak peek” video gives us a short glimpse on this simulation system, and reveals its name – MassFX.

As you may notice, MassFX resembles general design of standart PhysX plug-in from NVIDIA, but also includes some long-anticipated features, like substeps control, for example.

Autodesk webinar reveals plans on PhysX SDK integration into XBR

without comments

Autodesk 3ds Max users may be familiar with XBR (project Excalibur) – next major generation of 3ds Max products, that is supposed to adress many issues on fundamental level and includes some new features, currently beeing in extensive development stage.

Rumors have been floating around for some time, but it seems now it is official – recent webinar from Autodesk has revealed that Simulation sub-system within XBR will be based on PhysX SDK, instead of Reactor engine (using Havok).

Autodesk Webinar - XBR and PhysX

QA session after the webinar

Following webinar recording is giving a glimpse on some features and ideas for XBR Simulation system (starting 44:45).

Judging by XBR release date (when it’s done), we can assume that it will use PhysX SDK 3.x

APEX Clothing authoring workflow in details

with 11 comments

One of the main features of NVIDIA APEX framework is not only complexity or quality of simulation, but artist-focused authoring pipeline, that allows easy creation of physical content without significant programmer involvement.

Update: PhysX plug-ins for Max and Maya with APEX Clothing features are available.

Update #5: New complete set of official APEX Clothing tutorials.

Authoring process in promising APEX Clothing module (you can remember its debut in Mafia II title) goes through DCC plug-ins for 3ds Max and Maya.

Following tutorials (available previously for plug-in beta users) are giving perfect overview of clothing authoring process, basic capabilities and features, using 3ds Max plug-in as an example.

Tutorial I – Waving flag

APEX Clothing tutorial - 1

Tutorial II – Physically simulated Cape

APEX Clothing tutorial - 2

How to achieve quality simulation with PhysX plug-in for 3ds Max

with 5 comments

Those of you who are familiar with PhysX plug-in for 3ds Max (for example, recently released 2.40 version) may already notice that by default simulation is not going as smooth as you can expect – rigid body objects are often interpenetrating each other, jittering and jiggling (especially when stacked) , and so on – making it hardly suitable for some scenes.

UPDATE: Not valid for 2.60 PhysX plug-ins and above

So, we’ve contacted Gavin Kistner, Product Designer for PhysX Max and Maya plug-ins at NVIDIA, and he gave us several tips, using those you can deal with simulation stability problems in most of the cases:

TIP I – Increase Frame Rate

If rigid bodies are showing inaccurate behaviour, this is indicating that physics engine is just not performing enough simulation substeps between frames. To fix that (as separate substeps control is yet not availalbe in public versions of PhysX plug-in) you can simply increase Frame Rate before previewing or baking the simulation (and than revert it back to normal during composing, for example).

3ds Max PhysX plug-in framerate

To illustrate this tip, let’s set up a simple scene – several rigid body planks falling one at each other, trying to form a stack.

3ds Max PhysX plug-in low quality

With default Frame Rate – 30 fps (shown above), simulation is just messed up. At certain frame planks are stuck together, solver is trying to resolve inter-collisions and repels planks – stack collapses.

Autodesk Subscription Pack for 3ds Max 2011 includes 2.40 PhysX plug-in

with one comment

Now, when Subscription Advantage Pack for 3ds Max 2011 and 3ds Max Design 2011 was released, we can verify that it includes updated version of PhysX plug-in, designated as 2.40.0808.2140, avaialble in 32- and 64-bit variants and based on PhysX SDK 2.8.3.17.

Update: How to achieve quality simulation with PhysX plug-in for 3ds Max

Update #2: New PhysX plug-n v. 2.60 released

3ds Max PhysX plug-in v2.40

Unfortunately, APEX Clothing tools are in not included in this version of the plug-in.

Note: To use this plug-in with RayFire Tool, you need to update RayFire to version 1.51.02

For those of you, who still can’t decide if new PhysX plug-in is worth the update, here are full Release Notes we took from documentation:

v2.40.0625, 2010-June-25

Issues Fixed (Present in Previous Releases)

  • [#5023] Rotating collision shape on biped does not maintain position in space
  • [#4936] Resetting a project does not reset PhysX global settings
  • [#5022] Capsule’s shape is altered incorrectly when height or radius is modified
  • [#5061] Loading a project from 2010 with constraint fails to load in Max2011
  • [#5098] Constraint Swing Y and Swing Z reversed in UI

New Known Issues

  • [#5107] Baking rigid bodies attached to constraints yields incorrect results
  • [#5152] Baking to keyframes offsets values when Start Frame is not 0
  • [#5153] Initial Spin speed not in degrees per second

PhysX plug-in v2.06 for 3ds Max in action

without comments

Several nice videos were uploaded on YouTube by user named Phrogz42 (and further finding are indicating that Gavin Kistner, Product Designer for PhysX Max and Maya plug-ins, is hiding behing this nick) – they are showcasing usage of PhysX 3ds Max plug-in for simulation of several complex obejcts – mostly chains of various types.

But much more interesting details were revealed by autor today, as responce to our question – PhysX plug-in v2.06 Alpha (current version, available for public, is 2.01) was used to create those demonstrations.

Most simulations were running on sub-realtime performance, due to highly increased iterations count, but stability is impressive, not to mention that almost no joints were used – each chain link is compound obejct, consisting of several rigid body primitives/convex meshes.

Take a look at description of “PhysX Chain Braid” video – “each chain link is a single rigid body with eight automatically-derived convex hulls comprising 160 verts (per link)” – it seems convex decomposition algoritm has finally made it to PhysX plug-in.

We’ll keep an eye on Phrogz42’s channel and will let you know, if something interesting will appear.
