No, the module is Engine, you should already have it in your project. And including Texture.h is already enough as it inherits from StreamableRenderAsset.
Upon testing and digging up it myself, the issue seems to be that the methods are in a class that uses the MINIMAL_API macro, therefore the symbols won’t be exported. The functions would have to be explicitly marked with a macro (when MININAL_API is used) to be used outside of the module they are in.
You’d have to do something like either modify the class or implement your own version of it to gain access to the funtion outside of its own module.
