Hey guys. I have license question. If i was developing a game engine. and I want to use PhysX in my engine. Do i have to go and issue a license of PhysX to be able to use it in my engine? and What i want to do with my engine, is license it to other studio or people or whatever. So do i have to license PhysX and so does my customer that licensed my engine? I was wondering cause i saw, unreal engine supporting all sorts of other libraries, like speedtree and stuff like that. So by Epic saying we support speedtree in Unreal Engine 3, does that mean they have licensed that, and anybody who license unreal enigne 3 also licenses speedtree? regardless of whether he will be using that in his game or not? or the cusomter doesnt pay for speedtree license since (maybe im not sure) unreal already licensed it for unreal engine 3? thx

AGEIA has a whole set of web pages for developers starting at http://www.ageia.com/developers/index.html that has links to their licenses, SDKs, and documentation -- but I'm sure you read have read it.

Near the bottom of that page it says:

Quote: The Ageia PhysX SDK is free for non-commercial use. Standard pricing for commercial use is $50,000/title/platform. Licensed developers who implement PhysX accelerator support in their PC title are not required to pay this fee.

It appears that your two zero-cost options are either non-commercial use or meeting the terms of their licensed developers.

If you aren't satisfied with their published license, email their developer relations people and ask them the details and possibly work with you on the issue. They know, better than anybody here, what the terms of their own licenses are.

ok, so im guessing suporting physx in my engine can and can NOT be free. ill email them, and see how things go!

thx frob for ur reply :D
