My least favorite part is adding path nodes. It is soooo tedious about painfully boring. (especially when u have a huge map).

 

Pathnodes and constant map and script errors

This is probably the same as some others, but it would have to be limits. The fact that you can't create as much shit that you want is annoying. From terrain limits to brush limits, they're constantly there lingering over you until you hit them an have to reduce you in some way or another.

My least favorite part about mapping anyway.

Compiling. Adding path nodes and limits are not that annoying to me but whenever I need to change something little in the map, the fact that i need to recompile the map drives me insane :|

The image limit has definitely gotten in my way multiple times.
World at War being so old that sometimes it gives 10 RAM errors before finally launching the map is pretty annoying too.
The worst part is always wanting to work on it but on some days just lacking the creative mood needed for it. There has been times where I've had radiant opened for an hour and all I did was add 3 trees and just look at the map because I cannot get in the mood to have some creative flow. I guess you could call it mappers block?

Have managed to handle the 400 fx limit however limits less common I recieve are fx elem limit (which is the elements involved in fx) and 2048 material assets I still am not sure a fix on.

Having error, that can be cos of 6 different reasons 

well with Origins its patches.... Undead Town it was errors

The whole scripting aspect of it. It's blows my mind attempting to even do it. But the mapping side of things though i find really fun and rewarding. It's like minecraft just with way more options and features. But ya just scripting sucks. Just so many ways to get errors and not knowing how to fix them...... Cough cough *ascension 2.0* cough

i second this

Adding path nodes and zoning. Also if you call this mapping, errors

I must resubmit mine.. Id have to say the worst part is the days after release when you get the comments that this stat is wrong, this looks off, that guns name is wrong, and those people mostly don't even make maps!

Agree with you. I got shred to pieces when overflow released.

When mod tools in any way complains.
