Solved Which kind of alpha transparency does Mugen use?

Hi, I'm wondering what kind of transparency is used in Mugen games to not have black borders in some particle effects and flash fx?
Thanks for your lights

Try additive blending (A1). This is the closest I know of to OpenBOR's Alpha 1 mode. Mugen's algorithm can be rather finicky, so you'll need to make sure the sprites are clean and well made.

@DCurrent: Thanks, alpha 1 transparency is perfect . Problem solved!

@kimono, I'm moving this to the ask and answer area, marking the accepted answer, and setting solved prefix. In the future please do this yourself. Putting technical questions into general discussion areas and manually typing [solved] into the title isn't really useful for searching and organizing.

Ok, thanks DC, I will pay more attention next time. Sorry for the wrong posting section.

Ah, let me correct this information: the closest to OpenBOR's alpha 1 in Mugen would be A, not A1.
A1 would be closest to alpha 6 in OpenBOR.

There are some shortcut if you don't want to use "add source and dest", which is

A - add - draws with additive transparency (alpha defaults to 256,256)
A1 - add1 - deprecated in 1.1; draws with additive transparency (alpha defaults to 256,128)
S - sub - draws with full subtractive transparency (alpha is fixed at 256,256)

Changing the solve answer from mine to this.
