Currently, the ACC / Drive model viewer applies a single transparency calculation for overlapping objects. We would like to request a new feature to allow switching between multiple transparency rendering modes.
Proposed Modes:
Multiplicative Transparency (current behavior)
Example: Two objects at 80% transparency (20% opacity each) block the view so that the visibility of objects behind them is about 36% (current setting).
Minimum Transparency
Example: Two objects at 80% transparency and one at 40% transparency result in an effective visibility of about 60% (this is similar to how Navisworks behaves but Navisworks does not offer a toggle).
Additive Opacity
Example: Two objects at 50% transparency (50% opacity each) combine to make objects behind completely invisible.
Benefit:
These options would give users better control over how overlapping transparent elements appear, improving visual clarity when reviewing complex models.
