Help! My Outland and Ice maps look plain!

Okay, my Outland and ice (Icecrown, Northrend, Lordaeron Summer) maps have really plain-looking terrain. I have a few questions.

1. How can I improve maps of those tilesets above and make the look good without being overly doodadded?

2. How do I make blood on the ground.

3. I'm going to use that trigger that was posted today that allows you to go into buildings, but how do I make it remove snow when you enter, since it's snowing outside.

4. What pathing map makes it so that I could overlap doodads on each other but units can't walk through or on them, unless they fly over.

1. Variate tiles, add noise with raise/lower tools.
2. Don't know.
3. Should go in the trigger forum.
4. Use the pathing NONE and then add pathing blockers.

Can you give me the link to that thread with the enter house trigger?

Vagabond-

3) simple. instead of using a global weather effect, use regions and create them covering whole map except places you dont want there to be weather. then set those regions to have weather setting: Northrend Blizzard (or whatever snow setting you used in global weather, only this time double click region to edit its settings, and check the box for weather effect, then give it the snow effect)

for the blood effects look through the various model sections, like game extras and so on, i know theyre in there somehwere. there are loads of blood effects, some animated some not

Blood is under "Unit - Spawned Animations" or something.

and for the weather, have this:
Event - Unit enters (your building enter region)
Condition - whatever you need
Action - Destroy (Snow)

and at the beginning have this
Event - Map Init
Condition
Actions
Create weather effect at entire map of Northrend Snow (Heavy/light/blizzard)
Set Snow = Last created weather effect.

and then when they exit the building recreate the weather effect and set it equal to Snow.

for the blood u can kill a seal

:D Yeah, in the beginning of the map, give the players full sight and one minute to kill as many seals as possible to create blood effects... :D

Nah, create a doodad and put it's model to some of the blood effects there are. Believe they are under "Spawned Effects" or something...

Thanks for the help :D .
