I thought Decals arent possible in MP?
but anyway, as for the level lay-out...
Well...the first screenie looks good...maybe some lighting and it would look better.
But as for screenie 2...it looks like you placed some random entities
on random spots...
In my opinion, a MP-level would look and play better if you
stick to a theme...
So it could be like:
Sci-fi, scifi stuff and design..
WW2, ww2 stuff and design..
Unreal tournament kind of level...MP
(scifi, with mostly a symmetrical level design)
But, my personal favor is:
A level that actually represents something...
Like a certain theme, but also a level design what makes it look
real..
So for example a warehouse, that actually looks like a warehouse..
And not just a building with boxes in it and hallways that form
a labyrinth.
Anyway, would love to see more!
And good luck with this!
