How use engine class method in Plugin?

Maybe we solved, but now I got this errors.

This is where I use LandscapeFileFormatPng

Can I do that?

ExtraLifeMatt above explained what i mean :stuck_out_tongue:

you also need to move header file to Public.

Remeber that editing engine kind of ruins idea of plugin, because plugin user will also need modified engine in order to use your plugin, you could more effectivly add module from you plugin to the engine itself direcly
