Where will the Custom Maps belong in order for the game to run them

@zoolex 

There should just be a folder for them under My Documents, like with any modern game.

I've checked the AppData and Documents directories, it's not there yet.

I did find something interesting though, while digging around within the Game Directory, I found a possible location for the Custom Maps.

Tiberian Dawn

[GAME]\DATA\CNCDATA\TIBERIAN_DAWN\CUSTOMMAPS

Red Alert

[GAME]\DATA\CNCDATA\RED_ALERT\CUSTOMMAPS

However, I'm not sure if these are the official locations for User Created Maps, or any new Maps that were created for the Remastered Version of the game. These Directories have other files contained within them (FileTypes: '.MIX' and '.INI'). Something I noticed, when I saved my Custom Maps that I've been making (1 Fresh and 2 Port-Overs), The Creator saves a '.TGA' and a '.JSON' file in addition to the '.MPR' file that you'd expect to see normally.

It's fortunate that maps can be converted without any issues.

NOTE: I think it needs the '.TGA' file for the UI in-game, so it's best to load the Map in the Editor and save a new instance for usage in the Remastered Version of the game.

If the Remastered Map Editor supplied is too tiresome to use (due to the lack of a Copy and Paste function), then you can create map in RAED or Win95 RA Scenario Editor (or TD equivalent) first, and then load the map in the Remastered Map Editor.

I will say, adding units and buildings is a lot easier, but making the actual map is harder compared to the original Win95 RA Scenario Editor.

NOTE (For MOD Maps): If you intend to have maps with edited characteristics such as Ore Regeneration Rate, then you will be glad to know that the Remastered Map Editor doesn't get rid of the MOD Data internal to Maps. However, I haven't been able to test if the Maps run yet (the game not being fully released yet), though I will assume so. This said, the Custom Data does shuffle around automatically.

That may answer other things, but not this.

My question is in regard to Custom Maps, (User Maps), where are they installed?

I put the game on earlier, and I can't see my own maps listed either in the Map List (Bottom Right) or in the User Maps Section where you can download maps directly through the game.

@zoolex I don't have the game so I can't really answer this.

Maybe try to search in windows explorer by date and time for example around when you created the maps ?!!

@N7_A_M_R_Egypt 

I know where I saved them, I just don't know where the game expects them to be, so that the game will load them.

I have identified the location for Custom Maps (Created by the Local User).

Please note, the following Directories don't exist until you've played the game for the first time. Also note, this is based on a Windows 7 System.

C:\Users\[USER_ID]\Documents\CnCRemastered\Local_Custom_Maps\Red_Alert

C:\Users\[USER_ID]\Documents\CnCRemastered\Local_Custom_Maps\Tiberian_Dawn

The Map editor will memorise the location if the Directory exists (if not, you'll be taken to your 'Documents' Directory).

To play the maps in-game, go to your Skirmish Screen and click 'Custom' in the Bottom Right Corner (next to 'Rules').

Please note:

If you have a Custom Map that was created in another Map Editing Program, please load the map in the Remastered Map Editor supplied with the Remastered Version of the game, and then save the map in the appropriate Directory. This is so that there is a TGA File available to read in-game, and the TGA file map be needed for the Radar too.

Additional Note:

Imported Maps that were created using RAED will have two many Waypoints (as RAED automatically adds the Waypoints 'Home' and 'Reinf'). When saving them using the Remastered Editor, make sure that you only have 8 Player Spawn Locations and that the Waypoints 'Home' and 'Reinf' are removed. This is especially important if you've got an 8-Player maps. You'll know if something's wrong if the Map in-game shows 10 Player Map, and only 8 Player Spawn Locations.

Edited Post - Additional Information:

I don't know if it's due to a bug in the game, but Custom 8-Player Maps appear to crash the game.

I can't seem to use my custom maps for online game play.  Is there a way you found to do this?  I'm not sure where the "user maps" come from when hosting?  They look to be made.  

For those using Origin, not yet, since the game isn't fully ready yet. More of EA pushing games out to the shelf before they're finished products.
