Re: Is there any method to export .bullet file from 3ds 2012

I had the same problem and ended up building it myself for Max2012 64bit only. I can give you my executable if you like, but I made some small coordinate system changes. See my thread on the subject...

Re: PhysX Bullet plugin for Max 2012?

Sure thing, just PM me an email address to send it to. Did you see my note about the coordinate system changes? I'm still using the 2.78 build of it but we havn't had to re-export any of our data since converting to 2.81 so I don't think anything too drastic in the file format has changed. Like I sa...

Bullet & using Constraint Hierarchies(aka Ragdolls) with CCD

The short answer, it doesn't work currently as is. In our game we have ragdolls that can fall off of high enough structures that some of their smaller body parts will become embedded in the ground without the Continuous Collision System enabled on them. With CCD enabled, ragdolls will collide with t...

Re: Vertex skinning ragdolls?

Its a bit more complicated then that what it comes to implementing it, but more or less. You need to keep track of the transform offset to line up each bone (each bone that has a matching rb anyways) with its rb and apply it. You need to get all your hooks setup correctly to get the results of the c...

Re: PhysX Bullet plugin for Max 2012?

Has there been much demand for it? I'm a Maya guy myself, but my lead artist swears by Max and something around half of the games industry seems to prefer it. For the time being what we have works for us, but if we need more from it in the future, we may have to develop it further ourselves. In whic...

Re: btBvhTriangleMeshShape and btTriangleInfoMap serializati

I re-enabled that code as well and have had no problems with it thus far. Not sure why it was removed either. I still need to add the InternalEdgeInfo, good to know about that problem.

Re: Major contact stability improvement

So some changes have been checked into the main trunk... http://code.google.com/p/bullet/issues/detail?id=642#c8 I'm curious to see how this improves things and how it compares to the version of Bullet Mr Coulon's company runs. Maintaining the CCD system (which has also been improved now!) is pretty...

Re: Counter strike recoil feel

yep, he pretty much got it. There is no actual physics used in classic CS to do the recoil (or ballistics for that matter). Its been years since I worked on a FPS, but as I recall when I implemented it for anothe CS style game from that era I used a simple meter that accumalted the kick. Every shot ...

Re: Major contact stability improvement

Hi Erwin, Thanks for the reply. I will try to make a patch for the latest bullet version. Let me know what the name of the repository is on github. Otherwise I can post it on Google code. Let me know. Thanks for actually taking the time to post your discoveries! If these other changes and fixes you...

Re: Major contact stability improvement

Thanks for sharing your ideas and work. It will help if you update your work to the latest Bullet svn repository. I will create an up-to-date github repository, that makes it easier to fork/clone your modified version. Erwin, what do you think of these changes? Do you agree with them? Do you see th...

Re: PhysX Bullet plugin for Max 2012?

I ended up building it myself in 64bit against bullet 2.78. I don't mind sharing my build if someone needs it, but I've modified the TriMesh output to adapt Max's coordinate system to Maya's (Z forward, Y up, X left) so I don't know how useful it will be to others. It doesn't compile to 32bit yet an...

PhysX Bullet plugin for Max 2012?

Has anyone built this themselves yet? I see that the PhysX plugin hasn't been released since Bullet 2.77. I'm in need of a build for Max 2012 (32bit at least, perferably both), I don't believe the serialization stuff in Bullet has changed much since then but the newer the better for the version of B...

Re: problems building against Bullet for dynamica

Did you ever have any luck with this? I need to get a version of the Bullet exporter working in Max 2012. The PhysX plugin with Bullet intergrated was last released for Bullet 2.77 and it would probably be alot easier to get that building with the latest version of Max and Bullet, but it would be ni...
