This is my meager attempt to stop all the newbs, noobs, choobs and morons from flooding this once beautiful forum with repeditive questions and unintelligable banter.

The Tools=-=-=-=-=-=-=-=-=[/center]
-X-tra Editor-Used mainly for isometric tile placement, but is also uselful for placing basic doodads.
-SCMDraft 2-Also useful for isom. But moreso for square and sprite placement.

My person choice for terrain making, it has a good master palette, sprite layout and interface. However it's isom leaves something to be desired. I'm using StarForge in this tutorial by the by.
[center]Now onto answering those nooby questions!

How do I use / What's the palette?=-=-=-=-=-=-=-=-=[/center]
1. Download Starforge.
2. Open Starforge.
3. Locate the layer dropdown menu.

The red area is where you wanna be, click terrain.
4. Click on the red area that says "palette"

(The yellow area is how to switch between isom and rectagular tiles.)
5. You're done! The new window that pops up is a index of every tile on the current tileset. Scroll through it to find the wimsical blending pieces known as tiles.

1. Open a new document in your favorite isom making program. Make a cliff next to or on water.
2. Save it and re-open it in starforge.
3. Match up the tiles under water with ones from the palette.

Blending; The Imperfect Art.=-=-=-=-=-=-=-=-=[/center]
Not everyone thinks of blending right, so heres a quick rundown.
Blending is the art of taking a blocky terrain piece and making it look smooth or isom. OR taking one isom catagory somewhere it shouldn't be, such as temple to Jungle.
Example.

To blend al you have to do is open your blocky piece in Starforge or SCM and go into the master palette. From there go to the area with the type of terrain surrounding the blockiness, 8 times out of ten it'll be there. The other 2 times it's part of a doodad, which brings me to my final section (for now.)

Doodads and Sprites=-=-=-=-=-=-=-=-=[/center]
Doodads - The solid pieces of terrain mixed with a sprite. They cannot be walked through and rarely over.
Sprites - The non-solid pieces that can be walked completely under. Very uselful for covering crap.
To acces doodads in Starforge open the custom brush palette.

Just click the red area, then the other red area. Load the doodad brushes and you're all set.
To acces sprites go into the sprite layer. Click the button above the side GUI and voila.

Note the area outlined in red.
That's the end for now, if I discover more noobish question I'll add a nice guide for it. Good luck to all beginning terrainists. Oh and one more thing, DON'T DO JUNGLE.
