FPostProcessPassParameters::Bind() Link error

Development Programming & Scripting C++

Hello, everybody. I have a problem and I don’t know why. when I use ‘PostprocessParameter’, I will get a link error, **but I have already added “Renderer” to the dependency module list **in xxx.build.cs.

Here are the details of the error:


unresolved external symbol "public: void __cdecl FPostProcessPassParameters::Bind(class FShaderParameterMap const &)" (?Bind@FPostProcessPassParameters@@QEAAXAEBVFShaderParameterMap@@@Z) referenced in function "public: static class FShader * __cdecl FPostProcessSunMaskPS_ES2::ConstructCompiledInstance(struct FShader::CompiledShaderInitializerType const &)" (?ConstructCompiledInstance@FPostProcessSunMaskPS_ES2@@SAPEAVFShader@@AEBUCompiledShaderInitializerType@2@@Z)

Any help would be appreciated!

Any help would be appreciated!

You should also include the relevant header file which is


#include "Runtime/Renderer/Public/PostProcessParameters.h"
4

I added the header file you said, but it seems doesn’t work~~~ Is there any module I have missed?

Can anyone help?

I asked an experienced colleague and finally got the answer: because of FPostProcessPassParameters:: Bind() hasn’t a module API.Like its other functions.
This is the official explanation:https://docs.unrealengine.com/en-US/…API/index.html
