I am currently using the mutable plugin, but when I click compile in blueprint, I always encounter breakpoints to check (MaterialPin) in GenerateMutableSourceSurface; I don’t know what caused it, the engine was good when it was version 5.5, but this problem appeared in version 5.6, is it possible that it is due to the update of the node interface by Unreal Engine? Please help, thank you
It’s a language localization problem. The material pin name has been incorrectly localized in 5.6, which breaks the compilation.
You can either try to switch the editor to English or if you can work a little with source code, apply a simple fix which is already on the UnrealEngine github:
