Sets VDP2 Half Transparent Color Calculation Mode (only one mode can be used at a time).
- Parameters
-
| mode | The VDP2 color calculation mode to use |
| extend | Designates whether to extend color calculation to the top 3 Layer Priories instead of just top 2 |
- Note
- Extended color calculation has many restrictions detailed in VDP2 users manual- not all color modes can support extension simultaneously. If supported, 3rd priority pixels will blend with 2nd priority at a 50:50 ratio before the result is blended with top priority pixels. If unsupported the behavior is identical to non-extended color calculation.
