ReShade is for post-processing and post-processing only. I hope you know what shaders are and what they do and how post-processing operates differently from lets say a material shader. Anyway, ReShade works with shaders written in ReShade FX only. No HLSL, no GLSL, no CG. ReShade FX. Need for Speed has shaders written in HLSL. You would need to translate your post-processing shaders to ReShade FX or else it doesn't know what to do with them. Here's the reference document of the language:
github.com/crosire/reshade-shaders/blob/master/REFERENCE.md
Example HLSL:
sampler DIFFUSEMAP_SAMPLER = sampler_state
{
AddressU = CLAMP;
AddressV = CLAMP;
MIPFILTER = NONE;
MINFILTER = LINEAR;
MAGFILTER = LINEAR;
};Equivalent ReShade FX:
sampler DIFFUSEMAP_SAMPLER
{
Texture = SomeTextureDefinition; // << Variable name of a previously declared texture
AddressU = Clamp;
AddressV = Clamp;
MipFilter = Point;
MinFilter = Linear;
MagFilter = Linear;
};
There are quite a lot of samplers in that code which need a texture to sample from. Do you have the relevant image data? Without it you can't get anything to work here. Also, that vertex shader there won't work with ReShade either. ReShade renders three vertices (one single triangle), and does NOT move any data into the vertex shader. The NFS one (vertex_shader_passthru) expects quite a lot of input data, which doesn't exist in ReShade. It's also not specified how many vertices NFS would input there at all, but I highly doubt it's just three.
TL:DR: You can't just throw random shader code at ReShade and expect something to happen.
