Good day,
We have encountered an unusual behavior while using Three.js to display an STL model. When we attempt to enable transparency, certain parts of the 3D model disappear when they are obscured by another transparent component. However, other parts that are positioned behind the same transparent element remain visible.
As a newcomer to Stack Overflow, I am unable to include an image with my post. Nonetheless, you can view two screenshots illustrating the issue on my GitHub report: https://github.com/mrdoob/three.js/issues/7929
The first screenshot displays the external components of the model, while the second reveals that most of these components vanish when hidden by a transparent part.
The transparency feature seems to be functioning correctly, but specific parts mysteriously disappear. Our loader is an enhanced version of the standard STL-loader, incorporating modifications related to coloring.
Do you have any recommendations on what might be causing this issue, or if there is a flaw in our approach? Could it potentially be a bug within three.js itself?
I appreciate your input and apologize for any inadvertent violations of protocol on Stack Overflow.
