Libs3D Library

I am ready

As we have seen, when it comes to 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
• maybe some .glb files
• some .fbx animations

Create a new Gideros project and add the two folders in the assets folder:

• 3dbase
• luashader

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

Please create a models folder, and in this folder an objs folder. Copy the roadtovostok asset pack there.

Your file structure should look something like this:

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

.obj Rulez

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

• currently, for the .obj file format, 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 not use them.

The assets: .obj

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

In 3D, the assets you download from the net, often need some adjustement 🤷‍♂️

I made those adjustements and will use the pack I uploaded here: https://mokatunprod.itch.io/3dpixel-obj-packs. You can download this pack or use your own models.

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!
