Fixed crash loading the plugin on a custom ue4 macos project

[ilwoody]

Hello,

my compiled project , on a mac, was getting an assertion when loading the substance plugin.

It turned out the plugin code wasn't looking in all possible places for the libsubstance_sse2_blend.dylib  and missed the Project/Marketplace plugins folder where, in my case, the lib was. I didn't do anything fancy to have it built there, mine was a simple Ue4 with substance on a mac compiled via xcode.

So to avoid moving the lib by hand in one of the supported folder in `void FSubstanceCoreModule::StartupModule()` I've replaced this

Code: [Select]


        //The plugin can exist in a few different places, so lets try each one in turn
FString prefixPaths[] =
{
FPaths::Combine(*FPaths::ProjectPluginsDir(), TEXT("Runtime/")),
FPaths::Combine(*FPaths::EnginePluginsDir(), TEXT("Runtime/")),
FPaths::Combine(*FPaths::EnginePluginsDir(), TEXT("Marketplace/")),
};

with this

Code: [Select]


        //The plugin can exist in a few different places, so lets try each one in turn
FString prefixPaths[] =
{
FPaths::Combine(*FPaths::ProjectPluginsDir(), TEXT("Runtime/")),
                FPaths::Combine(*FPaths::ProjectPluginsDir(), TEXT("Marketplace/")),
FPaths::Combine(*FPaths::EnginePluginsDir(), TEXT("Runtime/")),
FPaths::Combine(*FPaths::EnginePluginsDir(), TEXT("Marketplace/")),
};

and now works properly.

@ilwoody ,

Glad to hear you were able to solve the problem.

Just to verify though, what folder did you place the plugin in? It should be in the project folder like this: *PROJECTNAME*/Plugins/Runtime/Substance
