NVIDIA Makes PhysX 3.3.3 Free to Unreal Engine 4 Developers

Following the free release of Unreal Engine 4, Epic has announced that, in partnership with NVIDIA, developers using Unreal will have access to NVIDIA’s PhysX 3.3.3 physics engine, plus its source code.

A statement from Epic Games reads:

“Today we’re excited to announce an expansion of that partnership with NVIDIA providing all UE4 developers with not just binary but C++ source access to the CPU-based implementation of PhysX 3.3.3, including the clothing and destruction libraries, through Epic’s Unreal Engine repository on GitHub.”

Epic is making great strides to make its game developer resources available to prospective creators for free, though the Unreal 4 agreement carries a 5% quarterly royalty charge on shipped games after the first $3,000 profit.

Epic’s statement continued:

“This means that the entire UE4 community can now view and modify this PhysX code alongside the complete C++ source code for UE4. Modifications can be shared with NVIDIA who will review and incorporate accepted submissions into their main PhysX branch, which then flows into future versions of UE4.”
