	# That makes our base, now make a func_emitter ~~and~~ select ~~the~~ particle (for example tdm_leaves_01).		# That makes our base, now make a func_emitter.
			# Now you need to select which particle to use (for example tdm_leaves_01). Select the emitter entity, and open the entity inspector. Right click anywhere in the Property list, and select "Add property...". Select the model folder, and in there select the model property and click Okay. This will bring you back to the entity inspector, now click on the newly created model property. Now two buttons will show up, click on the "Choose Particle" button. Browse through the list to find the particle you want.
	# Now select the particle emitter and set a key/val pair "shaderParm7" in the key and a value in the val. This controls how fast the movement of the texture is. When this is on 0 (which is default), there is no movement (which looks like there's no wind at all and the leaves stand still like in a screenshot). 1 would be some quite slow ambient movement while 2 would be a light breeze. 4 would be a windy place and about 8 would be a very windy place. Adjust the number to your liking. Note that this is only for the currently selected emitters, which means you can have no leaf movement for leaves in one part of the map, while in another part you may want them to be swaying like mad, for example.		# Now select the particle emitter and set a key/val pair "shaderParm7" in the key and a value in the val.

	# '''Model trees which use particles for the leaves:''' This method gives the tree a more "bushy" look because the particles are oriented to the player's view. This means that from whichever angle you look the leaves always look good. Of course, there is a problem with the particles being oriented to the player's view, and that is that they rotate to ~~math~~ the angles of the player's view, resulting in a "kaleidoscope" effect when viewed from the bottom or top and rotating the view.		# '''Model trees which use particles for the leaves:''' This method gives the tree a more "bushy" look because the particles are oriented to the player's view. This means that from whichever angle you look the leaves always look good. Of course, there is a problem with the particles being oriented to the player's view, and that is that they rotate to match the angles of the player's view, resulting in a "kaleidoscope" effect when viewed from the bottom or top and rotating the view. Also, this method puts more strain on performance and can cause framerate drops.

	So, firstly make a tree as above and use one of the default leaf particles (this is the simplest way). Make sure the map has a light lighting up the tree, so you can see it. Now open your test map in Doom3Ed and press F2 (this brings up the game in windowed) and in the console type EditParticles. This will bring up the particle editor in Doom3Ed and allows you to make changes, as well as see the result of them in the renderview.

	~~So, to~~ make a custom ~~leaf~~ material, copy the material ~~shown further above~~ and modify the ~~relevant~~ parts of it ~~(such as~~ name~~, paths to the texture etc)~~.

			To make your own custom material, make a .txt file and rename it to .mtr and open it with notepad. Then copy the above material and modify the parts you want and save it. It should then appear in DarkRadiant under the path specified in the name; so for this material it would be under textures/particles/ and would be tdm_leaves_01.
