Engine injection? Or wizardry? was created by ??sfvbfb
So PQ has lots of pretty shadersshader-like things and marble reflection and things, which TGE didn't have. I remember MBExtender(not the graphics extender) and didn't see any hints to graphics hooking. I'm not asking for the source code to pq's engine modsactually if any of you would post that then that would be really awesome but you won't but pls, but rather a starting point to do something similar. Like what MBExtender did with providing a framework to develop engine extensions in C++. If you can't tell me anything because top secret that's alright but it really would be cool to see how this engine that seems like it's older than I am has been pushed to do all it has been.TIA.

PQ's shader code is basically using MBExtender to its fullest extent. It took a lot of blood, sweat, and yelling at Jeff for them to put it all in, I'm sure.

If you're content with post-processing shaders (which you can actually do quite a bit with), Quaternion uses a watered-down version of PQ's shader system whose code will be released with the game next month.

Engine injection? Or wizardry?


Is "both" an acceptable answer here? :silly:

Anyway, I wrote MBExtender, and in general you can pretty much use it to do anything with the game that you want to if you're able to reverse-engineer the engine. The main goal is to provide a framework which lets developers easily run custom code, interface with the engine at runtime, and override engine functions. There's nothing graphics-specific in the public build of it mainly because the intention is for users to fill in function definitions themselves.

PQ's graphics plugin is pretty specific to what we wanted to do for PQ, so the only real framework that we have is our MBExtender fork with a bunch of Torque's graphics interface mapped out. It essentially works by overriding the methods for marble and interior rendering and then replacing them entirely with our own code. Then we can do whatever we want, including activating shaders and rendering a realtime reflection cubemap. It's pretty complex and took quite a while to get working correctly. MBExtender was started in 2014, the graphics plugin was started no later than 2015, and both of them together add up to about 20,000 lines of C++ code. Calling it "wizardry" isn't much of an overstatement, and I'm pretty impressed myself with what we've done.

Feel free to ask me if you have any more questions, but I'm not providing any code at this time due to several reasons.
