Hi,

Im looking for a game engine / framework to be integrated into an existing c++ application. I'm currently using an old version of Ogre3D, but i want to upgrade to something physically-based to produce photorealistic results.

I tried to look into commercially known engines like Unity or Unreal but those are mostly made to make standalone applications while i need to be able to embed it and use it like a library, without editor. So to sum up:

• Photorealistic PBR
• C++ or .Net based
• Framework or library that support embedding
• Could be free or not

If you have any experience / suggestion to share for such middleware i would be much appreciated, Thanks!

Had a look at C#.NET and OpenTK?

Hi, thanks for the suggestion! TBH i didn't know it. Looking at the API documentation it looks like a multi-platform version of SharpDX (in term of abstraction level…).

I'm looking for something a bit more hi-level, e.g. with an already working PBR shader (a material?) , maybe a shadow system, but nothing more than that.. thats why i was initially searching for AAA game engines but those are overkill for my project and not embeddable….

Ogre has had PBR capabilities since (at least) 1.10: https://www.ogre3d.org/2017/12/31/ogre-1-10-final-release

Why not continue using it if you already know it?
