You can use opacity trick (set Opacity to low and compensate it in Color and after render clamp Alpha channel).
Or you can use similar Emission trick as Krakatoa (what I understood from the online documentation). This method gives you same result but it's much faster to setup:
1. Use Mantra Surface shader.
2. Turn everything off except Emission (so “Enable Diffuse”, and “Enable Reflect” should be off“, and ”Enable Emission“ on).
3. Set ”Emission Color“ that way that no channel is equal to zero, (if you need more or less pure red set green and blue channel to very small value like 0.001).
This small value determines how fast it goes to the very bright (super white) color.
4. Set ”Opacity Scale“ to 0 for full ”additive" effect (and 1 is for no additive effect) (you need to render correct (desired) Alpha/Opacity in separate pass (with different material))
5. Enjoy
Cheers, P.Z.
