That is what I though when designing OpenIG. Since I sounded like placing a commercial in this thread (which I actually did, but this is OSG project) I will not spend too much on details here, but yes, the light implementation is hidden from the "scene", the interface. It has plugin-based approach and the lighting implementation is completely implemented in a way (simple or complex) again hidden. For example in the current repo you can find simple lights implementation very similar to what you are doing. Then this plugin in the upcoming release is replaced by F+ implementation, without changing the interface. So it will not break any code, it is simple replacing a plugin dll in a xml config file. Ping me privately or join the OpenIG forum if you want to give it a shot. I can help you set up And thanks, Nick On Fri, Jan 15, 2016 at 9:43 AM, Robert Milharcic < [email protected]> wrote: > Hi Nick, > > On 14.1.2016 15:31, Trajce Nikolov NICK wrote: > >> Hi Robert M. >> >> I went through this thread fast and I see you are trying (at least your >> show case) is lighting and use of shader composition.
