Glow Shader - How to use the alpha Channel

[Schoppy0384]

Hi,

 

first, Thanks shadmar for the great Glow Shader.

 

I need this Shader on a Plane with an Alpha Texture.

The Problem is, that the Glow Shader only works with the Solid Blend Mode.

 

Is it possible to use the Glow Shader with the Alpha Blend Mode?

 

 

Thanks.

You can't use blendmode alpha since glow is set in the emissive channel and the emissive alpha channel is used for flags.

But you can alpha mask it by adding this to the end

 

if (outcolor.a < 0.5) discard;

If you are using additive blending, youdon't need glow shaders, just the regular diffuse.shader as blendmode light will make it glow.

 

Your texture should not contain alpha as black/dark areas will be transparent, while light areas will blend additive.

 

mat should look something like this:
