[QUOTE=kees;1908]It is a pretty big mess though :P[/QUOTE]
OHH YES it is :D: !!!
If you plug their wizzard pre-setup post glow effect on top of your material : everything is working fine.
But I’ve never managed yet to create my own RTT from scratch : all I get is scrambled texels or pixels coming from somewhere from a buffer. In my case, I’d have to use their DECLARE_SIZED_TEX for fixed size render target.
I’ve scaled down and moved slightly to top right the screen quad vertices to keep an eye on it : the texture seems to appear fine, but I’d like it applied back on the object forwarded through “pass2” with “RTsampler” picked up by in pixel shader… weird… :?:
Here is the simple test.fx :
float4x4 WorldViewProj : WorldViewProjection <string UIWidget="None";> ;
float Script : STANDARDSGLOBAL <
string UIWidget = "none";
string ScriptClass = "object";
string ScriptOrder = "standard";
string ScriptOutput = "color";
string Script = "Technique=Textured";
> = 0.8;
// "NVIDIA's header way of doing it"...
// you can comment/uncomment to swap with some of these to try...
// none of them worked for me :(
#include <HLSL\\include\\Quad.fxh>
//DECLARE_QUAD_TEX(RT_Tex,RTsampler,"A8R8G8B8")
//DECLARE_SQUARE_QUAD_TEX(RT_Tex,RTsampler,"A8R8G8B8",256)
//DECLARE_SIZED_TEX(RT_Tex,RTsampler,"A8R8G8B8",256,256)
//DECLARE_QUAD_TEX(RT_Tex,RTsampler,"A8R8G8B8")
//DECLARE_SIZED_QUAD_TEX(RT_Tex,RTsampler,"A8R8G8B8",1)
// My way : classic texture/sampler declaration : "the way Rendermonkey is outputing it"
