Glow Shader - How to make it blink (fade in and fade out)

[R.E.Z.]

Hello,

 

I do work with Glowshaders in my Level.

Is there a possibility, to make the Glow-Light fade in and fade out (Only texture 5)? Like a blinking Light.

 

Great work by shadmar ... Glow Shader:

Might someone have a hint to me for that purpose?

I'm sure there's a better way but maybe you can use a combination of AddPostEffect and ClearPostEffects.

In the frag:

 

find :

vec4 outcolor = ex_color;

after add :

outcolor.a=1.0;

 

find:

fragData2 = vec4(texture(texture5,ex_texcoords0).rgb,materialflags/255.0);

replace it with :

fragData2 = vec4(texture(texture5,ex_texcoords0).rgb*ex_color.a,materialflags/255.0);

 

Then in your app use :

self.entity:SetColor(1,1,1,glowamount) 

 

to set glow amount, and now you can make a blinking or fading glow in code.

Very cool shadmar.

I still wish we had a way to get model instance specific data to shaders that isn't abusing the color field.

Hello,

 

thank You shadmar for the help

I did find the lines in the shader code.

 

But where do I set the third part, You listed?

 

Then in your app use :

self.entity:SetColor(1,1,1,glowamount)

 

Where do I find or edit this line?

Looks like that's in your Lua code - you change your entity's color and it will change the glow amount.

Hello,

 

I was digging for this line... but still could not find it.

Not in the FPSPlayer.lua nor in other scripts.

Where is this app file located?

Might someone have help for this question?

You won't find that line anywhere. He's saying that's the line you have to put in your code somewhere to make this shader work. That's how you control the glow amount when you want to use it.
