How to bake a opacity 3D model?

Baking opacity for a 3D model involves using 3D software (e.g., Blender, Substance Painter) to transfer transparency data from a detailed high-poly/textured source to a low-poly model as an alpha or opacity map. - **How it works**: The map converts see-through areas (like glass, fabric, or hair) into a 2D texture, so the low-poly model can show transparency without complex geometry. - **Beginner tip**: Try a simple object (e.g., a glass cup) in Blender: Add a transparent material to the high-poly source, select the low-poly as the target, and use the “Bake” panel to generate the map. This keeps your model lightweight while retaining realistic transparency—ideal for games, animations, or real-time use.
