No. 3D skyboxes are basically exploiting the size limit. You can always get creative with particle effects.
Does the CP need to have a "traditional" CP design, as in one that looks like it could work in a gameplay scenario, or can the CP be more of a detail item, with props piled on top of it/poking through it/etc.?
OnTopic: it's kinda hard to fill anything of interest around a control point with only 2048 hu. If it was 2048hu of walkable space, and then some out of bounds eye candy, sure, perfect scale, but right now I feel like my 2d skybox will be visible or I'll have to throw some random walls just to block it.
A few things;
- You're finishing this on Christmas itself? You might want to make the deadline a few days before, so we can play the full array of maps on Christmas, instead of in January.
- European will get screwed here. Shipping outside of the US costs a lot of extra money (like $20), so if they win, they won't be able to take any of the prices except the virtual ones.
I know that you can't really overcome that because it's your charity really, and it's Valve's fault of anyone's, but I'm just saying.
Just to make sure, will there be a "special" contest subforum again or are we just supposed to make a thread in the generic map showcase board with the according prefix ?
To answer your other question, 2048x2048 is the total maximum dimensions for the map - nothing whatsoever can be outside of this, but you can go vertical as far as you want with no limits.
