More PhysXLab tutorials: Fracture Maps and Multi FBX import

with one comment

NVIDIA has uploaded new portion of video tutorials, covering various aspects of APEX Destruction authoring process using PhysXLab tool.

First set of tutorials is explaining creation and usage of Fracture Maps – simple black-and-white images, that can be used to specify fracturing pattern for cut-out fracturing mode.

GPU PhysX in Batman: Arkham City

with 16 comments

Batman: Arkham City, sequel to award winning Arkham Asylum title and second GPU PhysX game this year, has finally hit the shelves worldwide.

Update: Batman: Arkham City – GPU PhysX Profile

As usually, we are proud to present you our PhysX review and comparison video, showcasing extra physical effects that can be found in PC version of the game.

Some technical details, like difference between PhysX settings, were already revealed in our preview article, so let’s give a score to different aspects of GPU PhysX implementation and compare them to previous Batman: Arkham Asulum title:

QUALITY 8/10

All effects are done accurately, with diligence – you will not see jerky or buggy behaviour (within physics engine limitations, of course), art is fine, almost everything is configured correctly. However, some particle effects could be done better – for example, it is not appealing to see when glass shards are jumping all over the place like they were made out of rubber.

AMOUNT 9/10

PhysX effects are scattered all over the game and accumulated in a places you will visit during main storyline (for example, you won’t see dynamic paper sheets on a random street).

Overall amount of extra physics content is similar to Arkham Asylum, but the components differ: you won’t see many “environmental” cloth objects, like all those banners and flags that can be teared appart with batarang, but in return APEX Clothing module is used extensively to simulate dynamic clothing on characters, including hoodies and coats on thugs, pants on russian twin-clowns, costume of Bruce Wayne, etc.

SPH smoke, steam and fog are rare in this game, but other particles (physical debris, shards, splinters, sparks) can be encountered much more frequently. All boss battles are enhanced with unique particle effects, for example.

As a good tradition, there is psychedelic level with lots of GPU Rigid Bodies. Looks gorgeous, actually, without PhysX effects this scene feels not nearly as vivid and spectacular.

PhysXLab 1.1 released with APEX 1.1 support

without comments

NVIDIA has released PhysXLab 1.1 Beta – updated version of PhysXLab, standalone authoring application for APEX Destruction and APEX Particles modules.

Release Notes:

  • APEX 1.1 support (PhysX SDK 2.8.4.6).
  • Possibility to have multiple physical meshes per chunk – convex decomposition (controlled by “Collision Quality” settings).
  • New options for “Playground” simulation – Radius Damage Tool, ability to throw or drop destructible asset, shoot it with box or sphere.
  • Separate pieces now detected by the FBX importer.
  • Can now import a multiple mesh and export without further fracturing.
  • Ability to cancel fracturing opertation – “Stop Fracture”.
  • Chunk instancing (correponding chunks between different destructible actors will be rendered through intance bufer).
  • Chunks tiling (matching chunks created from cutout fracturing will be instanced within the same actor, as well as referenced actors).
  • Visualization of instanced chunks.
  • LOD settings can now be applied to destructible in playground.
  • Supports ASDW keys to move camera.
  • Updated interface with support for all new features.

Bugs fixed:

  • Bad tangent generation fixed.
  • Large memory usage issues fixed.

PhysXLab 1.1 can be downloaded through Developer Support Center. Follow the path:

[Online Support] -> [Downloads] -> [APEX PhysX Lab (beta)] -> [APEX PhysXLab 1.1 (beta)]

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

APEX Destruction presentation from MIGS 2011

without comments

Autodesk has uploaded several partner presentations from Unreal University event at MIGS 2011 (Montreal International Gaming Summit).

One particular session – “UDK Overview || Nvidia session” – is provided by NVIDIA, in which Johnny Costello, PhysX content engineer, gives overview of APEX Destruction module functionality and it’s usage inside UDK (starting from 30:00).

This session covers pretty basic Destruction authoring features (PhysXLab, slicing, depth settings, playground, exporting to UDK, etc) – so for those who is already familiar with APEX or previosly released tutorials (set #1, set #2), it won’t say anything new. However, it is worth watching for a beginner.

Note: one interesting feature was mentioned during the presentation – in near future Destruction module will support objects deformation through joints.

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

without comments

NVIDIA has already pleased us today with updated tutorials for APEX Clothing module, but this is not all -  a bunch of new tutorials for APEX Destruction module, focused on usage of destructible assets with UE3 or UDK engine, has arrivied just a hour ago.

Update: Destruction tutorials package (with destructible assets, textures and UDK levels) was added to Developer Support Center.

Not familiar with APEX or its integration in UDK ? Start with these links: APEX Destruction | APEX 1.0 Beta | March UDK released with full NVIDIA APEX support

APEX Destruction Tutorial with UDK: Fracture Materials (2)

This tutorial describes how to use fracture materials in UDK.

APEX Destruction Tutorial with PhysXLab: Wood Material (3)

This tutorial provides step by step instructions for creating a destructible wood plank using PhysXLab 1.0 or higher.

Siggraph 2011: The Latest Advances in NVIDIA PhysX and APEX Technology

with 2 comments

Autodesk has published a recorded video of a presentation – “The Latest Advances in NVIDIA PhysX / APEX Technology” – that was performed by Daniel Horowitz, engineering manager for PhysX dev. tools in NVIDIA,  at Siggraph 2011.

This presentation is covering such topics as design principles of PhysX and MassFX plug-ins, relationship between those tools, and is also giving an overview on APEX Clothing authoring process and upcoming features.

Some interesting facts:

  • APEX Destruction functionality will be added to PhysX plug-ins in the future. It was also mentioned, that it will be possible to use to use 3d party tools for fracturing (not only default solution in PhysXLab) and also tweak graphical and physical meshes separately.
  • Next release – PhysX plug-in 2.7 will support PhysX SDK 2.8.4, PhysX SDK 3.1 and APEX 1.1
  • APEX Softbodies module was mentioned.
  • Contact Layers feature (basically, collision filtering) will be added in 2.7 plug-in for Maya, and 2.x plug-in for 3ds Max.
  • Patner integration program. For example, PhysX based rigid bodies from Particle Flow plug-ins will be able to interact with MassFX rigid bodies.
  • mCloth module will be based on ClothFX plug-in from Size8Software, but it will fully interact with MassFX rigid bodies, ragdolls, atachments and so on (nice solution to keep PhysX cloth and APEX focused on clothing simulation for games only).

It was promised that new 2.7 PhysX plug-ins will arrive shortly, in a few weeks, so keep an eye on our website for a full review.

APEX Clothing tutorial: from Maya to UDK

without comments

User monkeYB07 has posted a video tutorial, that covers APEX Clothing authoring process in Maya and further importing of completed clothing asset into Unreal Development Kit.

Update: New complete set of official APEX Clothing tutorials, including assets import and usage in UE3/UDK.

Basic result, working dynamic cloth, can be achieved in less than 10 minutes, but proper tweaking will certanly require more time.

For additional details on APEX Clothing authoring workflow you may refer to NVIDIA tutorials and APEX C page at Unreal Developer Network.
