Anyone got a gamma shader?

[DLPB_]

Just need a basic shader for FF7 that increases gamma / brightness.  FF7 PC seems to have wrong lightning vs PSX and I need something to compensate.

Try reshade, it does work with OpenGl based games. It has sweet.fx and other post shader. I recommend HDR, FXAA and Filmgrain.

Not sure where I am with all that?  Is there a simple file I can use to just alter a gamma amount and pop in the ff7 shader folder?

I haven't installed FF7 so I cannot test it and I've never written a GL fragment shader. But some time ago I emulated the old BSNES gamma procedure in cg.

I tried to copy it to GL by editing the bloom2 shader:
Code: [Select]

// very simple bloom shader, shamelessly stolen from http://myheroics.wordpress.com/uniform sampler2D tex;uniform float width;uniform float height;void main(){   vec2 texcoord = vec2(gl_TexCoord[0]);   vec3 res = texture2D(tex, texcoord).xyz;   res = (res > 0.5) ? res : pow(res * 2, vec3(1.5))*0.5;      gl_FragColor = vec4(res, 1.0);}

But as I said I can't test it on my system. So yours might explode If I got the correct syntax at all.


If it does not work you might ask the guys at the libretro.com forum in the shader section.
