Before i start i want to say that all this info is on the BF2 editor forums and there are other tuts that use terragen and T-paint, but i must admit when using some things for the first time i came up with all sorts of head aches so i thought i would have a go myself!
Also i would like to add this will not make a good map alone, and it will not make a map in minutes like so many people think, these are just tools of the trade and used in the right hands you can produce some stunning results. There are lots of things that make a good map and having a good terrain is one of them.
I am splitting this tutorial into 2 sections 1. Terragen 2. T-paint. I would suggest before you go about making your map you atleast make some basic test maps following the standard EA tutorials otherwise you will be lost and also you will not know what buttons to use. For instance Terragen is an amazing product like world machine etc... but you still need to know how to smooth, lower etc... your terrain in editor. The same as T-paint this only gives you a base to work on and thats it, you will still have to texture your main areas by hand and mix textures together to get the right effects
Right for this tut i am going to use the following programs,
T-Paint
Secondary Heightmap Generator
Terragen
bf2 editor
Photoshop
(with .dds plugin)
by all means if you wish to know just T-paint move to that section. i may also go into more things later on in the tut
Getting set-up.....
Load up editor and select BF2, even if you are working on a PR map just select bf2 as this saves you messing around importing objects. If you wish to import PR object into your map make an objects folder in your bf2 deirectory and place everything in there.
Now we want to start a new level and select a map size, for this tut we will use 512 x2, just remember this size for future reference. If you choose 1024, 256 write it down on a post it note and stick it to something you look at often, your girlfreinds behind, your pet dog, your todger....
Once loaded up all we are going to do is save and exit editor. Congratulations step 1 done
You can create your terrain using editor just using the sculpt tools or you can try your world generator program like we will be doing in the tutorial
STEP 1. Terragen
First of all make sure you have a look where you map folder is, the standard place is...
C:\Program Files\EA GAMES\Battlefield 2\mods\bf2\Levels\your map name
Ok lets load up terragen...
Once loaded you should see somthing like the followig screen....
Now we are going to select size and remember the level size i said? if not find that sticky on your dog etc.. We used 512 so we will press 513, 1024 maps select 1025 and so forth. You will get load pop screen pop up, dont worry just hit ok, yes etc..... then just click ok in the window to get rid of it.
In the Landscape window we are now going to click generate terrain and the terrain genesis window will appear...
I will try to explain the options, firstly the pull down window is what method you wish to make your terrain, Realism, smoothing, glaciation, Canyonism should be self explanetry but this controls how the end map will look, how smooth, how deep the canyons, how tall your mountians. For this tut i am using the following options. but have a play it wont do any harm. When you have something you are happy with click ok
Next thing we need to do is in the landscape window is click modify...
in the 'Show height filed' tick the box next to Terrain units, then set the height range from 0 to 164 then click set height range, then click close.
You should end up with somthing like this.
From here if you like you can click on 3d preview and fly around your newly created world or go back and edit some more until you get something your happy with. You can sculpt by hand also, have a play until your happy.
Ok now we are ready to save our work, in the landscape window click Export, select Raw 16 bits Intel Byte Order, then click (select file and save)
Now find your hieghtmap primary raw folder in the following location...
C:\Program Files\EA GAMES\Battlefield 2\mods\bf2\Levels\your map name
Select this and click save, this will now generate your hieghtmap.
Ok now we are done with Terregen
STEP 2. T-paint
First of all make sure you have the T-paint folder inside your map folder
C:\Program Files\EA GAMES\Battlefield 2\mods\bf2\Levels\your map name
Also quickly pop into editor and enable surrounding terrain
we will cover this before we t-paint If you want to use the standard textures in T-paint you dont need to worry about the next bit.
Ok first of all we are going to extract all the bf2 paint textures from our bf2.zip which is located...
C:\Program Files\EA GAMES\Battlefield 2\mods\bf2\common_client.zip
Browse this zip and find the folder...
Common_client.zip\Terrain\Textures\Color
now extract these into your documents or somewhere you know where they are.
Ok now we are set up so we can start playing
First if you browse you T-paint folder there is a folder called data (this has confused many so i will try to explain)
inside this folder you will see some TGA files, high, low and steep
High =high ground
Low = low ground
Steep = mountains, cliff faces etc...
So go back to your folder you extracted all those lovely BF2 textures to and choose what you want. For this i am going to use..
Slopes.dds for high
muddy.dds for low
grass.dds for high
We need to convert these files to a TGA format that t-paint can use, so all we need to do is load up Photoshop...
Select each file..
Slopes.dds and save it as steep.tga (24 bits/pixel) and then place this in your T-paint/data folder, then do the same for muddy and grass.dds
If you notice in this folder also it has a grad_height and grad angle TGA, you can edit these also which will allow you grass and mud to mix and what angle you want the slopes texture to start. For this tut i am going to leave them as standard.
Ok thats all the colour setting up done.
Now we need to generate the surrounding terrain before we T-paint. We are going to use bf2 hieghtmap generator. Just place the highlighted files into you level folder. Now if you are reading this properly i did say to pop into editor and enable your surrounding terrain. if you have not done this do this now.
So you now should have in your levels folder all of these files...
Ok first lets generate our surrounding terrain, navigate to your map folder and right click on generate shortcut and then click edit, change the 0 value to 256, then click save. (low detail of surrounding terrain)
Now back in your levels folder double click on generateShortcut.bat, this will then look at you main terrain and generate all your surrounding terrain for you.
Ok now back into editor and where your main terrain meets your surrounding terrain we need to use the smooth tool (just so it meets up exactly).
Now into T-paint....
Ok in your map folder/Tpaint double click on BF2 Tpaint
Leave all of them ticked for now and click go... (T-paint generate 2 BMP files colormapbig.bmp and detailmapbig.bmp which you can use later if you like, if you want to keep these untick delete temporary files)
Now go to the T-paint directory in your map folder and copy the following folders to this directory Yourlevel/editor
OK now back to editor to finish up
Once you load up you will probably see something similar, dont worry as now we are going to assign detail textures and generate low detail textures...
ok now select the paint tool and you need to assign the colour textures,
1 for steep so we used slopes for the colour and then assign textures, in the low detail type assign this to 2 (tweaker bar)
2 for high (grass), set low detail type to 1
3 for low (mud), set low detail type to 1
Now we generate low detail maps....
Now you should have a finished terrain ready to start putting grass, trees statics down. You can smooth out, level areas of your map now and then run T-paint again until your happy.
Here is a screeny from one of my WIP maps using this method. As you probably will notice i have adjusted the fog to the sky colour to give the best effect possible.
Advanced Stuff
Terragen...
You can use terragen to create the 3 textures the T-paint uses, you do this by creating the 3 colours and using the Terragen options to lay them on the surface, then by taking a BMP pic of the map layout you can use this as the colour and detailbig.bmp files that t-paint uses. There is a tutorial in the bf2 editor forums on this process.
T-paint
If you can remember i did say to untick delete temporary files when you T-paint your level. Now the colour big file you can load into Photoshop and use it to create your undergrowth file.
First in your map set up an undergrowth grass layer, paint it onto your terrain so it generates this file, Now in Photoshop load up your undergrowth.raw file and with your dropper tool note the colour that is used for your grass, note down the file information and the size of the file. Now open up colorbig.bmp and you will see red, green and blue sections indicating where the colour is on your map. If you are viewing in RGB mode just delete the red and blue layers so your left with just the green layer (grass), now resize your image to match the undergrowth raw file and change the green to the rgb values of the undergrowth raw file. Now save this as 1 channel, 8bits depth, greyscale, 1025x1025 for a 1024 map, 513 for a 512 map, 257 for a 256 map. Save and now your grass is exactly where your grass colour is. This saves time painting undergrowth on your surrounding map areas that people only really see from a distance, you can also do the same with the overgrowth file
but now on my surrounding terrain. theres these little squares. like the gird is appearing through the textures. any way i can fix this?
