How would i combine these 2 separate projects?

i am trying to combine the 2 projects “Inventory With UMG” and “[Community Project] WIP Weather & Ocean Water Shader”
i am having trouble with trying to figure out how to set the playable character up to use the inventory/health system from the “Inventory With UMG” and still use the TP_VehicleController From the “[Community Project] WIP Weather & Ocean Water Shader” project to be able to control the Ships/cannons/etc while being able to access the inventory/health system.
ive experimented by adding the same variables and re-creating the same blueprints of one of them into the other, both ways around, with no luck.
at this point, im at a stand still in this project i am working on and i cant seem to find anything that helps with what i am looking for.
please, if you have ANY ideas, do not hesitate to comment.
Thanks!!!

usually for basic moving and combining of projects you would use migration and or copy the and merge the content folders. the issue is that you need to know what you want to copy over files wise, what has precedent in the case of both projects having some of the same files, and then once done you will need to know how to combine the blueprints that you need to combine and how to set project defaults.

there will be a fair amount of work to be done on your part to make the move happen and be successful. i dont have those projects downloaded so i cant really give too much specific information.

Thank you for the response. I dont seem to get many on this answer hub.
I have migrated everything i need ans i am able to set up either of the controllers to be playable, but not at the same time. One controlls the HUD/inventory and the other allows you to control the ships (vehicle controller)
I’ve taken the bkueprints and did a copy over and made it basically the same set up in the other blueprint, but still nothing. Im just at a stand still at this point till i can figure out how to either use both at the same time (combine) or set a trigger to activate it.
