BBMOD 3 - a successor of BBMOD 2 - is an advanced 3D rendering solution for GameMaker Studio 2! It consists of a custom model and animation file formats (*.bbmod, *.bbanim), a model convertor (BBMOD CLI), a powerful and easy to use GML library, as well as PBR shaders using which you can render models textured in professional, industry standard software.

Package contents:

  • BBMOD CLI - A command line interface for converting 3rd-party model formats (using Assimp) into *.bbmod and *.bbanim.
  • A powerful GML library using which you can load and render BBMOD files with ease.
  • A demo project for you to explore!

GML library contents:

BBMOD GML library is siplit into multiple folders - modules. Each one of them adds extra functionality - ranging from BBMOD model conversion on runtime, through advanced rendering techniques to interfaces with 3rd-party libraries. The only module you have to import into your project to use BBMOD is the Core module.

  • Core module - Contains code essential for loading models and animations, animation playback, basic rendering, batching models for increased rendering performance, as well as a math library for easier manipulation with vectors, quaternions etc.
  • DLL module - Exposes the functionality of BBMOD CLI to GM using a DLL.
  • Mesh module - Using this module you can create BBMOD meshes through code.
  • Importer module - Using these you can load some model formats without converting them to BBMOD first. Currently only *.obj importer is included.
  • Camera module - Contains a first-person and third-person camera with mouselook. With the Renderer module this is a great combo to start making 3D games using BBMOD.
  • Rendering module - Contains submodules related to rendering.
    • Cubemap submodule - Contains a struct using which you can easily render scenes into a cubemap.
    • Depth buffer submodule - Contains shaders for rendering scene depth.
    • FXAA submodule - Contains fast approximate anti-aliasing shader.
    • PBR submodule - Contains physically based (PBR) shaders and materials with full support for the metallic-roughness workflow.
    • Post-processing submodule - Contains shader with color grading, chromatic aberration, grayscale and vignette post-processing effects.
    • Renderer submodule - Contains a renderer struct which greatly simplifies 3D rendering.
  • State machine module - Contains a general-purpose state machine, as well as a state machine for animation playback control.
  • ColMesh module - ColMesh is a popular solution for 3D collisions by TheSnidr. This module contains functions using which you can easily add BBMOD models into a colmesh.

If you would like to learn more about individual modules and their contents, see the Modules section in the documentation.
