Problem
Glass, smoke, and translucent objects are poorly isolated and lose their recognizable form.
Solution
Root Cause / Diagnostic:
Using binary hard-edge selection tools on semi-transparent elements (smoke, vapor, glassware) converts delicate transparency gradients into jagged, opaque clumps or erases them entirely. The translucent object loses its ethereal quality and looks messy.
Actionable Fix:
1. Use Calculations or Channel-based masking (extracting luminance from the Red or Green channel) to capture organic alpha transparency gradients.
2. Composite smoke and vapor assets using Screen or Lighten blend modes directly over dark backgrounds rather than attempting hard cutouts.
3. Review translucent edges against both light and dark backgrounds at 100% zoom to verify smooth, natural transparency falloff.
Pro Tip:
Never use standard lasso or wand cutouts on smoke or glass; use channel-based luminance masks and Screen blend modes to preserve natural translucency.
