ues Editor Utility Widget When importing the model, the compiler always compiles the shaders automatically. Can I get a certain return value after the completion of the compilation of the shaders, which is convenient for me to continue the follow-up work so,how to check compiling shaders finished …

You can get that using c++. There are couple of functions available. such as GShaderCompilingManager->FinishAllCompilation(); GShaderCompilingManager->IsCompiling() There are more useful functions you can get from that class. And you have to include #include "ShaderCompiler.h" Thanks.

Can confirm this still works in 4.26.1 - Thanks for the tip!

Set this up for my project. Works fine / perfect in editor, standalone and launch game. But in the packaged build it crashes. Any ideas / help much appreciated. for clarity heres my function UFUNCTION(BlueprintCallable, Category = “Shaders”) static bool IsShadersCompiling(); bool UCPPFunctions:…

not sure i follow. the whole fasset part. Im pretty decent at C++ but occaisionally stuff like this make me realize i dont know jack. The GShaderCompile bit makes sense to me as its the reference in the shaderComile.h to the class with the function. I tried using GetNumRemainingJobs, since isComp…

FAssetCompilingManager is a layer above the GShaderCompilerManager (has a list of IAssetCompilingManager - which is what FShaderCompilingManager is derived from). I was thinking it may be that GShaderCompilingManager is a nullptr? Using FAssetCompilingManager will hopefully have that list of mana…

more or less follow. I see the connection from gshader to fshader but wasnt able to find the fassetcompilingmanager to go digging through it Oddly enough if i just locally save isCompiling to a bool it runs. but if i try to use that bool as the output back to crashing… on second thought i wonder if…

maybe make the method non-static (just remove the static before the bool in the header)?

hmmm, good catch. I copy paste my headers all the time making new functions. Bad habit. and a static setting when not needed has bit me on the ■■■ before testing

fingers crossed, but nope still crashed Thanks for trying to help out. Gotta shift gears now. Lost too much time to this today and now gotta refactor this out of the code… boooo. Was stoked when i came across this as I was looking for something like this for awhile now. One of my problems to solve…

There’s

FShaderPipelineCache::NumPrecompilesRemaining()

Tom Looman has some good info here:
