November 2012 release of UDK adds APEX 1.2.1 support

with 6 comments

Latest November 2012 UDK Beta release features updated NVIDIA APEX integration, which is now based on APEX 1.2.1 and contains a set of new features for Clothing and Destruction modules.

However, current release does not include APEX Turbulence module (moreover, there are no plans to release Turbulence publically), and is still using 2.8.4 version of PhysX SDK.

Release Notes

  • General
    • All APEX debug visualizations supported with “apexvis” command.
    • Get APEX stats with “stat apex”.
  • APEX Clothing
    • New embedded PhysX 3 cloth solver (old/new solvers will be auto-selected depending on the clothing asset type).
    • Local Space Simulation.
    • Improved material mapping allows actors to override asset materials.
    • Support for different number of LODS in clothing asset and skeletal mesh.
    • Fix for displaying correct physical clothing LOD in AnimSetViewer.
    • Improved DCC tools (2.86 PhysX plug-ins).

February/March UDK supports NVIDIA APEX 1.1

with 14 comments

Almost a year has passed since NVIDIA and Epic Games presented APEX 1.0 integration in Unreal Development Kit (UDK) engine.

And now, February 2012 release of UDK can “please” us with silent introduction of newest APEX 1.1 Framework, which includes updated APEX Clothing and APEX Destruction modules.

Unfortunately, UDN documentation was not yet updated, and some flaws were found in this release - for example, APEX GPU Rigid Body libraries are missing from the February distribution. Not to mention, that not all APEX 1.1 features have made it into UDK.

UPDATE: March UDK is released. Issues with missing GRB libraries were resolved.

UPDATE #2: November 2012 release of UDK adds APEX 1.2.1 support

Please note: only assets created with latest authoring tools - PhysXLab 1.1 and 2.71 DCC plug-ins - are compatible with APEX 1.1

Let’s take a look on some of the new features in APEX 1.1 integration we were able to discover:

APEX DESTRUCTION 1.1:

For additional data on Destruction Module please refer to UDN page

  • GPU Rigid Bodies (GRB). One of the most interesting features of 1.1 release is new ability to calculate rigid body physics on CUDA-capable GPUs, thus achieveing performance improvement in scenes with many destructible actors and simulated chunks, while using exact same assets and settings as for CPU physics.

----- Following is valid only for February 2012 UDK

As we have mentioned, current GRB implementation is missing vital libraries and also has some bugs: you can either wait until March UDK release or try it out now (for your own risk) – using our .dll package (36 mb).

Copy “GRB_1_x86.dll” and “pxtask_cuda_x86.dll” to “UDK\Binaries\Win32\” folder.

Copy “GRB_1_x64.dll” and “pxtask_cuda_x64.dll” to “UDK\Binaries\Win64\” folder.

---- Previous is only valid for February 2012 UDK

Now, to enable GRBs you need to set following parameters in “Engine\Config\BaseEngine.ini” file:

bDisablePhysXHardwareSupport=False

ApexGRBEnable=True

APEX Destruction and UDK: Tutorials

without comments

YouTube user has presented several tutorial videos, explaining basic principles of APEX Destruction module usage inside the Unreal Development Kit engine.

Update: New tutorials provide in depth view of APEX Destruction usage in UDK

First tutorial is covering basic principles of mesh fracturing using PhysXLab tool.

NVIDIA APEX and UDK: Destruction Project

with one comment

Since March version of Unreal Development Kit, that has brought us NVIDIA APEX integration, users are playing with the new features trying to figure out their capabilities and limitations.

One of the most noticeable examples is this Destruction Project by the user named RU1NOUS. Even in current state it is demostrating nice a clean level design, good usage of general APEX Destruction features and interaction of APEX actors with tearable cloth objects.

Currently, APEX Destruction still requires a lot of work to make it really powerful and practical fracturing/destruction simulation tool, so let’s hope NVIDIA has all necessary additions on the roadmap.

We’ll try to keep the eye on RU1NOUS’s work and will update this post accordingly.

March UDK released with full NVIDIA APEX support

with one comment

Epic Games has announced March release of Unreal Development Kit (UDK), free version of Unreal Engine 3.

March UDK includes all DX11 features, that were presented in Samaritan Demo at GDC 2011.

Important DirectX features now shipping with UDK include:

  • Tessellation and displacement;
  • Geometry shaders;
  • Multisampled textures; and
  • Shader Model 5.

In addition, UDK is now fully integrated with NVIDIA APEX, high-level scalable framework oriented on creation of complex physical effects, like destructible environment of dynamic character clothing.

NVIDIA’s APEX technology has also been integrated into the engine and ships with UDK.

NVIDIA APEX technology enables artists to quickly generate physically simulated clothing and destructible environments.

However, to take advantage of APEX functionality, authoring tools are needed to be released by NVIDIA. According to our sources, this may happen very soon, probably within a week.

Update: APEX 1.0 Beta released

GDC 2011: Epic Games announces DX 11 and NVIDIA APEX integration with Unreal Engine 3

with 6 comments

NVIDIA and Epic Games are teaming up this week at Game Developers Conference to showcase latest additions to Unreal Engine 3, like DX 11 support and NVIDIA APEX Framework integration.

“Thanks to NVIDIA’s excellent cross-platform physics technologies and DX11 expertise, we have enhanced Unreal Engine 3 to bring unprecedented new levels of realism and demonstrate what the next generation of gaming will be,” said Mark Rein, vice president of Epic Games.

Alpha and beta versions of certain APEX modules were used in UE3 based games previously (Dark Void and Batman Arkham Asylum), but now full APEX toolset will be available to all UE3 licensees and UDK users as well, and can be used to create high-fidelity physics content (character clothing, for example) even in CPU PhysX and console games.

January UDK: now with PhysX for iOS

with one comment

UDK logo PhysX

Epic Games has released latest, January 2011 version of Unreal Development Kit (UDK), free edition of Unreal Engine 3.

One of main highlight of this version is enabled PhysX functionality for iOS development, while previous Mobile UDK featured only basic collision detection system.

Mobile

  • PhysX is now supported on iOS.

Rigid body physics, fracturable meshes and ragdolls are among supported features.
Note: Cloth, fluids and soft bodies remain disabled on iOS for performance reasons.

According to our knowledge, this has became possible thanks for standalone PhysX SDK port for iOS (previously, only Unity Technologies have possessed their own custom iOS PhysX port  – for Unity 3D engine).

However, this time we may hope that iOS PhysX SDK will be available for public download someday, along with Windows, Mac OS X and Linux versions.

September UDK comes with PhysX SDK 2.8.4.

without comments

September Beta version of Unreal Development Kit (UDK), a free version of the Unreal Engine 3, is available for download.

This month’s build of UDK features significant additions, including:

· UDK users now have access to the gameplay profiler tool.

· Matinee’s movement tracks can now be split into individual translation and rotation components.

· Users can bulk edit texture properties within the Content Browser.

Apart from other usefull changes, September UDK is upgrading PhysX SDK integration with newest features of 2.8.4 SDK, like driverless destribution, SSE2 optimizations and enhanced cloth solver.

Also, we have noticed full pack of NVIDIA APEX .dlls – when APEX will be released to public, you’ll be able to use it with UDK right away.

· ‘PhysXDestructible’ has been removed.

· APEX destructibles are replacing them.

You can download September UDK Beta here or here

As for APEX Toolset release (without it APEX integration into UDK is useless for regular developer), several sources are indicating that this is going to happen somewhere in October ;)
