Libs3D Library

I am ready

As we have seen, to make more advanced 3D, Gideros has a bunch of helper files packed in the Library folder.

I will try to impress you with 3D Gideros ✨.

Here is the plan:

• start with shapes
• add some .obj models
• add some .fbx animations

Please create a new Gideros project and copy the two following Library folders in the assets folder:

• 3dbase
• luashader

Create a models folder, and in this folder an objs folder. Your file structure should look something like this:

• YourProjectName
  • Plugins
  • Files
    • 3dbase
    • luashader
    • models
      • objs
    • main.lua

You can run your project, you should have a blank screen.

.obj Rulez

When you work with 3D, you need to follow some "engine" rulez. In Gideros, for the .obj file format, those are:

• currently Gideros supports Base Color, Texture map and Normal Map
• the textures shouldn't be embedded in the models. In Blender, use unpack resources:

• your Blender BSDF shaders should look something like:

• Gideros will import the position of the models, so make sure your models are at location 0, 0, 0

• I believe Gideros also imports the origin of the models, so place the origins accordingly

I personally use this Blender add-on: https://extensions.blender.org/add-ons/act-game-asset-creation-toolset/

Please note, you can still have the Metallic, Roughness and other textures in your Blender BSDF shaders, Gideros will just ignore them.

The assets: .obj

I have chosen this cc0 asset pack: https://roadtovostok.itch.io/road-to-vostok-assets-vol1.

In 3D, the assets you download from the internet, often need some adjustement to follow your "engine" rulez 🤷‍♂️. I already made those adjustements and you can find the adjusted asset pack here: https://mokatunprod.itch.io/3dpixel-obj-packs.

Please copy the roadtovostok asset pack (or your own models) in the objs folder:

• • • models
      • objs
        • roadtovostok

The Ground

As we are more learning than making a game, we won't really care if the 3D assets don't match 🤷‍♂️!

I am out 2

To do.

You are strongly encouraged to mess with the code.

Bye for now!
