STEP 3: Choose Your Container
This guide is part of Green Chapter’s Beginner Paths: Mecha & Moss. In this series, we explore how to combine miniature landscapes, moss ecosystems, and model kits to create immersive living worlds with structure, storytelling, and atmosphere.
Follow the guides in sequence for the best learning experience.
Match your story and scale to the right space
In the previous step, you explored your scene freely — adjusting terrain and positioning without limits.
Now, everything changes.
You are no longer working in open space.
You are placing your idea into a real, physical container.
This is where many layouts start to break.
From Concept to Constraint
A scene that looks perfect on a table may not work once confined.
You will start to notice:
- the terrain feels too wide
- the model no longer fits naturally
- elevation becomes too tight
This is not a mistake —
this is part of the process.
The container forces you to refine your idea.
Scale Comes First
Before anything else, match your model scale to the container.
For 1/144 (HG models):
- compact scenes are possible
- single-subject layouts work well
- easier to control composition
For 1/100 models:
- require more space
- need wider terrain support
- cannot fit into small containers realistically
Trying to force a larger model into a small space will always break the illusion.
Why SKYBOX Works
For Mecha & Moss builds, the SKYBOX becomes the most reliable container, functional with a full glass cover and an elegant floating bottom glass.
It allows:
- proper spacing between terrain and model
- natural elevation and layering
- flexibility for both simple and complex scenes
Whether you are building:
- a quiet What-If scene
- or a more dynamic Canon recreation
SKYBOX gives you the room to make it believable.
Common Mistake
One of the most common beginner mistakes is trying to preserve the exact layout from Step 2.
This rarely works.
Once inside a container:
- spacing must be adjusted
- terrain must be compressed or reshaped
- the model may need repositioning
The goal is not to copy your plan —
it is to adapt it.
What You Should Focus On
At this stage, your goal is simple:
- test if your scene still works inside the container
- adjust terrain to fit the available space
- ensure the model has proper support and balance
You are not adding plants yet.
You are refining structure.

What You Should See
At this stage, your scene should still feel clear — but now grounded in reality.
You should be able to see:
- how the terrain fits within the container
- how the RX-78-2 sits within that space
- what needs to be adjusted before building begins
If the layout feels too tight or unbalanced, refine it now.
This is the last stage before you commit to structure.
Continue to STEP 4: Build the Landscape
Now that your layout works within the container, it’s time to make it permanent.
You will begin fixing your terrain into place —
turning loose materials into a stable, believable environment.
