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
- objs
- 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!
