Thank you very much for your efforts!

Hi,

I'm trying to add this to my own project with A7. I've converted the CScript code to lite-C and I noticed that when I try to enable the effects, the framerate drops but the effects don't show up? Here's my code:

PP_Effects.c:
Code:

---

#include "main.h"

// Blur in all directions (Lowquality)
MATERIAL* SimpleBlur_mat =
{
	effect = "simpleBlur.fx";
}

function SimpleBlur_set_Value(Blur)
{
	SimpleBlur_mat.skill1 = floatv(Blur);	// should be higher than 1
}


// Blur in all directions (Highquality)
MATERIAL* ComplexBlur_mat = 
{
	effect = "complex_blur.fx";
}

function ComplexBlur_set_Value(Blur)
{
	ComplexBlur_mat.skill1 = floatv(Blur);	// should be very small between 0.001 and 0.05
}

---

PP_Main.c:
Code:

---

#include "PP_Effects.c"

VIEW*  PP_Cam;

BMAP* ppe_quad = "graphics/PPE_Quad.tga";

ENTITY* PP_Quad = 
{
	type = ppe_quad;
	layer = 1;
	view = camera;
	flags = VISIBLE;
	x = 10;
	y = 0;
	z = 0;

	scale_x = 1;
	scale_y = 1;
}

function PP_Init_startup()
{
	PP_Cam = view_create(1);
	PP_Cam.bmap = bmap_for_entity(PP_Quad,0);
}

function PP_Init_Effect()
{
	PP_Quad.material = ComplexBlur_mat;//Change this to the material you wish<---------------------------
	ComplexBlur_set_Value(9.0);			//Call here the function to set the materials values<-------------
	

}

function PP_Toggle_OnOff()
{
	if(PP_Quad.flags & VISIBLE)
	{
		PP_Cam.flags &= ~VISIBLE;
		PP_Quad.flags &= ~VISIBLE;
	}else
	{
		camera.flags |= VISIBLE;
		PP_Cam.flags |= VISIBLE;
		PP_Quad.flags |= VISIBLE;
		
		while(PP_Quad.flags & VISIBLE)
		{
			vec_set(PP_Cam.x,camera.x);
			vec_set(PP_Cam.pan,camera.pan);
			wait(1);
		}
	}
}

---

And in main.c I added:
Code:

---

	PP_Init_Effect();
	PP_Toggle_OnOff();
	on_z = PP_Toggle_OnOff;

---

Thans.

Hey thanks, be able to look at shaders now

Would anyone happen to know how to stop the bloom shader affect the fog less? At the moment applying bloom with fog seems to intensify the bloom alot and I don't know how to stop it. Any ideas?

Code:

Yeah, you have to change these values:

Code:

---

float Luminance = 0.08f;
static const float fMiddleGray = 0.18f;
static const float fWhiteCutoff = 0.8f;

---

However... this will influence the entire scene. There's no really nice solution to this problem, unless you figure out a way to do the fog on top of the bloom somehow. I figure that would be possible through some sort of custom made fog code,

Cheers

already tried to darken the fog color itself? that should work quite satisfying

I think it might be a video card thing, Ge force 6600, as changing those values, changing the color of the fog to very dark, still the same effect, even though the intensity of bloom changes the fog comes in really close....Thanks for your help
