As much as possible, because it totally depends on the amount of layers. A single 8192x8192 image is not a problem until you add dozens of layers for editing. The ground texture for the new map I am creating is almost 500 MB (.psd file) now. I have 3,3 GB RAM and I am still able to make changes to that file without 'lag'. Until I start the Emergency 4 editor (for example) as well... If you don't have ANY modding experience, DO NOT create a new map. It's not just placing objects. Without Photoshop experience you can't even create a nice ground texture for it.
Not the axis setting how the door needs to open and how many degrees. For example: Y axis, 90 degrees I am not sure but I believe you need to press Enter after entering a value and then press OK in the childs editor (where you add doors). Try that.
By spending time on it. It doesn't have to be perfect, but at least try to make it look more round. You know how most tools in Zmod2 work. The only thing you are missing is experience. Just try and make sure you are patient enough. You can't learn it in a couple of hours.
Besides some objects and a few new buildings there won't be alot of new models in the first release of the map (also a beta release). I am trying to release this map as soon as possible. Creating new models take a lot of time and are not really necessary now. The map will be improved later by replacing buildings and objects.
The last PM from you was about my .exe installer. Besides that, I have absolutely no idea how you want to realize this. Do you actually have any experience with setting up custom window stuff in .xml files? And who are 'we'?
Player 1 (host) Player 2 Player 3 Player 4 Who gets what in which spot of the fire station. It's not smaller. It is the same size as any other freeplay map. That means a ground texture of 8192 by 8192 pixels. There are 2 main roads and the LA river and bridge are large and also take up a good part of the map. To save time on creating the texture I am adding larger buildings mostly.
