	~~Get the latest blender 2~~.63 and up should do it. Blender can render images as large as your ram allows.. I've found that on a system with four gig of ram I can render easily and reliably a 2049x2049 height(Displacement) map, translated into game units thats a 32x32 map size. more ram would allow larger maps, not sure what Spring's map size limit is.		== Steps ==
			1. Delete Cube and Light

	~~if your ram restricts you from making large maps, get the plugin, the name escapes me now but it allows~~ you to ~~render any size image in any number of pieces and stitch them together using imagemagick. ive successfully rendered a 32Kx32K map with this method.~~		2. Create Terrain Mesh
			- add plane
			- enter edit mode
			- scale plane to size you want
			- subdivide plane to match grid
			- enter object mode

	~~== Begin ==~~		3. Add Multires Modifyer
	* Open up blender		- set subdivision to simple
	* Delete the default cube and the light, since they arent used		- subdivide until level 6
			- set preview level to 6

	~~== Add a Plane ==~~		4. Sculpt Terrain Mesh
	~~Were going to be using blender units as Spring Map Units.~~		- enter sculpt mode
	~~The newly created plane size is 2x2, scale it by 4 to get 8x8 etc.~~		- set transform locks
			- sculpt
			- enter object mode

	~~== Add another plane ==~~		5. setup camera
	* Add another plane to ~~use for the water reference~~		- select camera
	* Scale it up to ~~roughly~~		- set position and rotation
	* Name it		- change to camera view
	* Put it on the second layer so you can turn it on and off easily.		- set camera to ORTHO
	* Turn off your ability to select it using the outliner		- set scale

	== Render ~~Settings ==~~		6. Setup Render
	~~FIXME~~- ~~need discussion on non square maps~~, ~~pretty sure the largest dimension wins. anyway...~~		- set render dimensions
			The height map resolution is defined as SMU * 64 + 1, see [[Mapdev:height]]

	* Change the renderer to ~~cycles~~		7. Setup compositor
	* Change render resolution		- change space type to node editor
	~~The height map resolution is defined as SMU * 64 + 1, so for this map, 8x8 = 513x513~~		- select compositor nodes
	* Make sure render percentage is 100%		- check use nodes
			- redirect Z
	~~== Camera Settings ==~~		- add normalise
	* Move camera to [~~0,0,?] z needs to be higher than he highest point on the map~~		- add invert
	* Rotation to [~~0,0,0~~]		- render
	* Adjust clipping to be [0,?] ~~as large as it needs to be so that the bottom of your map isnt cut off.~~		[[File:Blender-node000.png]]
	* Change camera to orthographic
	* Set orthographic scale to the largest SMU, our map is square so its 8
	* Move the camera to layer 3 to make it managable
	* Turn off your ability to select the camera in the outliner

	~~== Shading ==~~
	* Select your terrain
	* Change the material to the only available option(default new material)
	* Select Use Nodes
	* Change type from ''Diffuse BSDF'' to ''Emmission''

	~~=== Height ===~~		8. Colour Management
	~~The image below shows the node setup I use~~ to ~~render a height map.~~		- set display device to none

	~~Once you are finished sculpting you will modify the add value and the divide value based on your completed terrain~~.		9. Save
			- set type to tiff
			- set BW
			- set depth to 16bpp

	*~~The Add node is used to raise the terrain height values to compensate~~ for ~~being negative z values or under water in this setup~~. ~~it will have to be manually set~~		==Additional Information==
	*~~The Divide node is used~~ to ~~give maximum precision of black and white values and should be the maximum z dimension of~~ your ~~terrain, found in its transform properties.~~		* Need discussion on non square maps, camera settings for altering which dimension gets priority when rendering.

	~~=== Incline Map ===~~
	~~The below~~ image ~~shows~~ the ~~node setup I use to do two things:~~
	~~# Check while sculpting if terrain is walkable or buildable~~

	* subdivide the plane to create the exact number of verts that you will see in game

	~~w,subdivide 9 times 2,4,8,16,32,64, 128, 256, 512~~

	* Change to sculpt mode and set up the restriction to only transform on the Z Axis
	* Sculpt away

	~~I also use basic mesh editing to flatten certain areas with falloff enabled, this lets me scale in the Z direction to give truly flat areas for building on etc.~~

	~~== Render ==~~
	* Happy times!

	~~== FIXME ==~~
	* make the height map node properties driven by the terrain values.. so no manual adjustment is needed after the fact.
