I packed my project as shipping mode with some custom c++ node.

When the game ran and executed this c++ node and I got fatal error pop up!

I’m sure there were issue like this and probably has an answer?

Updated.

I found the way to core problem (probably).

I used #include “ShaderCompiler.h” to get number of compilation.

When I put  
int32 NUM\_SHADER = GShaderCompilingManager-\>GetNumRemainingJobs();

My package was crashed during this execute.

But when I tested with pure value int32 NUM\_SHADER = 999;  
There is no crash on my package.

Anyone can help me?

It turns out you can’t use GShaderCompilingManager on packaged project.

This function for editor only.

And that’s why it makes packaged game crash.
