World size

[jman0war]

sorry for the newbie question.
But i'd like to model an outdoor area with the intention of importing it as a static mesh in gtkradiant, then exporting it and using it in a game.

But before i start, what are some common "world sizes" that i might try and adhere to?
I mean the overall size of the cell, the edges of the world?

Note: you'll likely run into other engine limitations before just the max map dimensions. Stuff like polycounts, collision data, max surface counts, etc. There's no real figure we can quote for these, I recommend starting small and less ambitious and build your way up.

You can make one almost as wide as the radiant grid, but not quite. Source: my Skyrim stupidity.

You couldn't make that out of brushes, because q3map2 has a brush limit, among others. You also can't add much more to that map, lest you risk insane compile times, terrible framerates and q3map2 crashes anyway.

Using the _blocksize worldspawn key, you can actually compile huge maps very fast, if the brushwork isn't complex or dense. The problem you start running into as well is lightmap limits, if you compile with light, without using _lightmapscale, but then of course the lighting looks like ass. This game is a pain in the ass to make large maps in
