Self illuminated, transparent shader

[kreso22]

Hi,

First to say I spent 2 days trying to create my own solution with no success. What I gained from these 2 days is some knowledge of shaders, and a huge appreciation for what 2Dtk can do and does (as I was browsing source code for reference).

For my 2D, unlit game I would like to change shade of color for the sprite. I can change sprite's color with 2Dtk editor utility and still stay at 1 draw call, which is great. But the sprite will look too dark.

Is there any way to achieve effect like Self-iluminated/Diffuse shader? The effect that I get by just applying Main Color parameter is marvelous. Unfortunately shader doesn't work with transparency. And ideally keep at 1 draw call (edit material tint via script).

I am thinking only change current shader (tk2d/Blend Vertex Color) and somehow multiply values or something, but I don't understand shader rules.

Any help is appreciated.



Thank you in advance,
Kreso

Change blend mode to additive.
Eg. Blend SrcAlpha OneMinusSrcAlpha to Blend SrcAlpha One
That will probably do something similar.

Thanks a lot for the suggestion. I tried combining all the blend modes and didn't succeed in achieving the effect.
Then I took a step back .. basically I have a greyscale sprite that I want to tint with color. So I tried making it brighter in grayscale - and it worked.
I know this sounds obvious and I should have done that right away... but I did it now.

Thanks a for your help!
