LDraw-based addons for free games (SuperTuxKart, YSFlight, etc.)

[Eugen]

There are many LEGO-based games:

On June 13, 2019 Playground Games released "Lego Speed Champions" expansion for "Forza Horizon 4"


What you think about creating LDraw-based addons for free games?

For example, I could recommend create LDraw-based (using free MOCs, without official LEGO sets or any copyrighted MOCs) addons for next free games (or recommend other):

• SuperTuxKart - free & open-source cross-platform 3D racing game (for Linux, Windows, Mac OS, Android and other)
  
• YSFlight - freeware 3D flight simulator, but not limited to flight simulation only (for Linux, Windows and Mac OS)

As for SuperTuxKart 0.6 there was LEGO-like addon:

Also there was Tente3D-like addon for SuperTuxKart:

Addons for SuperTuxKart and YSFlight could be created using Blender (with some Blender addons). And LDraw parts/models could be imported to Blender, so Blender is recommended for such LDraw-based game addons creating.

There should be few categories for game addons:

• Scene - city, landscape (for example, reuse "Datsville" project);
  
• Vehicles - aircrafts, cars, vessels (controlled by gamer);
  
• Ground objects - buildings, trees, other objects (non-controlled by gamer);
  
• Characters - minifigs (gamer avatars; optional)

What you think about creating LDraw-based addons for free games?

The main problem with this is LDraw isn't optimized for game rendering as a model contains many polygons which will never be visible and thus waste cpu/gpu time.

Although on modern cards this isn't a big issue when using a handful of smaller models but things like datsville will bring your hardware to its knees without some sort of optimization process.

A great example would be Stefan Garcia's "BrickSpace" mod for Homeworld Remastered.

However, he spent a huge amount of time and effort manually optimizing these models. You can't simply build a model in LDCad and export it directly into a game. You have to do things like cut out the internal polygons and "bake" the studs into the textures. Not sure if Stefan ever created a "making of" video. That would be interesting to watch.

I also personally messed around with creating a RPG Maker game.

Since the graphics are all 2D, you don't need to optimize the models much. However, the engine was not designed with large, moving, and overlapping sprites in mind, so you need to implement lots of "hacks" that slow the engine down (and are also a PITA in other ways).
