BlendMode.ADD too bright on Windows target

[Miguel M.]

Hello,

I am trying to use the ADD Blendmode in order to achieve a sort of lighting effect. It seems to work fine on the flash target, but is too bright when targeting Windows (almost like Hardlight):

Flash:Windows:

Has anyone come across this issue before, or know of any solution?

Enabling Openfl-Next makes the game unbearbly laggy.

Thank you in advance!

Did you try on Neko?

No; why?

[Ashiq A.]

No particular reason; just to see which of the other two it more closely resembles. Neko is pretty easy to set up and build against (the Neko installer comes with Haxe).

Neko wields the same results as Windows :(

Bump?

[Ashiq A.]

Can you please open an issue on the HaxeFlixel repo in GitHub?

You should get a faster/better answer.

(Please share the link -- I would like to know the answer to this...)

I see that you did (and it got closed/redirected to OpenFL).

If you can reproduce this in a simple OpenFL example, you can post it on http://community.openfl.org.

[Miguel M.]

Already opened an issue on OpenFL :)

Additive effect on computers is performed by the graphics card, but in Flash - by CPU's software (simplified) algorthms. Seems that the brighter picture on Windows target is correct.
Of course, you also can use Photoshop, put one image on top of another with the use of Add effect and compare result with an image obtained on PC.

[Miguel M.]

Photoshop matches the Flash target behaviour, as described in the Expected/Seen; even if the blending itself has to be correct, something is not okay with ADD on native, further evidenced by the fact that alpha doesn't change the overly bright layer on windows (whereas it does on Photoshop and Flash).
