Transparent parts
How to prepare transparent areas so they can be handled as clear material.
The key rule
If you want a part (or part of a model) to be transparent / clear, it must be uploaded as a separate object.
That means: one object = one material intent. Keep transparent geometry separate from opaque geometry.
Why we require a separate object
Transparency isn’t just a “visual setting” for printing. The portal and quoting workflow needs a clean way to treat clear material as its own piece of geometry so it can be reviewed and processed consistently.
When transparent and opaque triangles are mixed inside one mesh/material setup, it’s easy for exports to lose intent or become ambiguous.
How to prepare your files
For transparent / clear parts, textures don’t matter (they won’t be visible through a transparent material). What matters is keeping the geometry separate:
- Export the clear geometry as its own object.
- Export the opaque geometry as its own object.
Name them clearly (for example window_clear and housing_opaque) and upload them as separate models in the same project.
