What is the exact issue currently?

#

You said that the problem was the the slash was "transparent" but I understood that's what you wanted, just not additive transparency

candid folio
#

I guess the slash should not be transparent, unlike what's shown in the image

#

The red part is still additive despite setting it to alpha

quiet violet
#

Did you try other blend modes as well?

#

Premultiplied may help

#

Opaque will confirm that something changes

#

Did changing from additive to alpha change it at all
I don't know as it's the same picture you posted before changing anything

candid folio
#

So apparently opaque does this

#

premultiplied makes it larger

quiet violet
#

Larger how?

candid folio
#

But the other two are pretty much the same

#

wait a sec

quiet violet
#

Opaque can also be used for particle effects but you usually want to use alpha clipping together with it

candid folio
#

larger

So alpha clipping just removes it entirely

quiet violet
#

Alpha clipping uses "alpha threshold" to determine where the cutoff point is

candid folio
#

Works perfectly now, thank you

quiet violet
#

Great! It's cheaper to render too

#

Though it doesn't have semi-transparency

#

Blending red and light green will always result in pink to some degree but premultiplication matters

#

I don't know what type of premultiplication the "premultiplied" blend mode uses but as a more practical example if your texture fades to black when it fades to transparent, it'll be less pink

#

Pure white base texture, fades only on alpha channel

#

Also fades to black on color channels together with alpha

#

If that makes sense

candid folio
#

Alpha was how black/white the image was, right

quiet violet
#

Alpha is the fourth color channel, for transparency

candid folio
#

Okay I genuinely knew that, trust me

#

But alpha interacts with black/white in certain settings, right

quiet violet
#

I think the only interaction of alpha and color are that alpha determines the amount of alpha blending to do with the chosen blending mode

Rendering/Blending Mode determines how to blend according to alpha value
Alpha value does not have a relationship to RGB color information (including black or white)
Some Blending Modes' transparency is affected by RGB values, in addition to alpha
For example with additive blending black is fully transparent, with subtractive blending white is
