The Alpha tab adjusts translucency over the lifetime of a particle.
Start – Min/Max
- This is where the start alpha translucency of a particle is set.
End – Min/Max
- This is where the end alpha translucency of a particle is set.
Blend Alpha and Color
This setting is used to have the alpha tab affect additive blend images. Without this setting checked, any adjustments to the alpha will not apply, as an additive material uses RGB and not alpha to determine translucency. With this setting checked, you do not need an envelope transition (an end value) on the sprites Color for an additive material. This value should remain unchecked on blend mode images.
Envelope
Here an envelope can be applied to the alpha transition. Please see Notes about Envelopes/Tables for more detailed information.
