Hi there!
I'm trying to understand and reproduce wraiyth' tutorial on post process
shaders ( http://www.moddb.com/members/wraiyth ) with the Orangebox SDK.
I managed to compile the fxc-files and i got the compiled vcs files in
my <mymod>\shaders\fxc folder.
I had to make some changes to the shaderlib source to compile though.
(Seems like valve changed some stuff)
In post_sepia.cpp i changed:
pShaderShadow->EnableTexture( SHADER_TEXTURE_STAGE0, true );
to
pShaderShadow->EnableTexGen( SHADER_TEXTURE_STAGE0, true );
// correct? EnableTexture() takes a Sampler_t as a first argument...
.
And I changed:
pShaderShadow->VertexShaderVertexFormat( fmt, 1, 0, 0, 0 );
to
pShaderShadow->VertexShaderVertexFormat(fmt, 1, 0, 0);
And:
BindTexture( SHADER_TEXTURE_STAGE0, FBTEXTURE, -1 );
to:
BindTexture( SHADER_SAMPLER0, FBTEXTURE, -1 );
// correct? BindTexture() now takes Sampler_t
I compiled it. I got the game_shader_dx9.dll in <mymod>\bin
So I try to take a look at the postprocess shader using:
r_screenoverlay shaders/post_sepia
But I see nothing :(
No error message, no sepia.
Does anybody have an idea how I could get this postprocess shader to work?
[complete changed post_sepia.cpp]
