What is your anti aliasing settings? These affect max export size in a big way.

My standard export size for the community atlas maps is 8192 pixels in the largest dimension, with 25% antialiasing which normally gives me no trouble at all.

In any case, a way to export maps beyond your capabilities is to export them in tiles instead of the whole thing at once.

And yes, running out of memory in this context is running out of the 4gb it can address.

The SYMBOL DEFINITION layer is where all the symbol definitions live. When this layer is hidden, all symbols in the map gets hidden.

What you see on the BATTLES layer is the symbol references, that point to the definition on that layer.

That's doable, but you'll need to export the map in sections to accomplish that. I've done up to 200,000 x 200,000 that way.

I belive he did, see the URL near the end of his post.

Disabling delayed symbol drawing should fix it.

Type DELAYDRAWSYM on the command line and set it to 0 (Disabled)
