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.
