Hint #1: Changing gameplay settings

You can change all the gameplay settings of Proun! Like make a super slow mode, or give away boosts every two seconds, or a mode in which you build up to infinite speed really slowly...

The simplest way to do so, is to open the file Proun\Data\Settings.dat in Notepad and edit the settings. However, you cannot submit highscores anymore if you do, so be sure to backup the original file first to reset settings after playing around!

To permanently change settings without loosing the right to submit highscores, you can also copy existing tracks and edit the settings there (in the Settings.txt file in the track's folder). There are not as many settings there as in Data\Settings.dat, but you can just copy settings to the track's settings to use them anyway!

Hint #2: Changing the soundtrack

You can add your own songs to the soundtrack! Just put them in the folder Proun\Soundtrack and Proun will use them automatically! Proun can only read .ogg and .wav files.

In the Championship, each track has a fixed song, so your new songs won't be used there. To hear your own songs in the Championship mode, you will need to overwrite the original soundtrack files.

If you have made a custom level and want to set your own song for it, then you should put the song in your track's folder and set it in the Settings.txt of your track using a line like this:

music_songToPlay = MySong.ogg

Hint #3: Adding sun rays to your track

To put a sun rays effect in your track, like there is in Proun's third track, create a mesh in your level with this exact name: LightShaftsSource, and make sure it is pure white. Note that this effect works best if the background is a bit dark. (In case you happen to be interested in how these sun rays work on a technical level: there is a blogpost about it here.)

Hint #4: High Dynamic Range Lighting

You can use HDRI in 3D Studio MAX. This makes the entire screen a lot brighter or darker when you are in a certain area, as happens inside the big planet in Composition #1: Through. You can use this to make certain parts of your track very dark when looking at them from a distance, but make them brighten up when you are actually racing through them. Check chapter 7 (Gameplay objects) in the Proun level editing tutorial.pdf that comes with the game for how to get these custom HDRI objects in 3D Studio MAX.

Hint #5: Free camera view around your track

By editing the file Proun\Data\FreelyEditableSettings.dat and setting showDebugWindow to true, you get an extra view in-game where you can look around your map using the mouse and the numpad. This can be very handy to check whether things look the same in-game as they do in 3D Studio MAX.

Hint #6: Changing the gameplay of the original tracks

If you want to create additional modes for the original tracks, you can simply copy the existing tracks and give them new names, since you can edit all the properties per map. You can then just upload your modified track as a ZIP and link it on this forum, so that people can download it and add it to their game. Please don't distribute modified versions of Track05, though, since that track is for paying players only.

A couple of specific hints for how to do some fun things:

-You can make a mode without cable by opening the track's file Scene.txt in Notepad and removing the line that has Cable.mesh or CableMesh.mesh. This keeps the mesh for the cable from being loaded. Beware of line wrapping, though: you need to remove the entire line, even if it is too wide for Notepad to show it on a single line.

-You can change the texture of the cable by opening the track's file Materials.material in Notepad and searching for CableMaterial.png. Just change that to some other image. Be sure to put the file you change it to in the folder of your track, though!

-You can modify all speed settings and create new, ultra fast modes by simply making the current ones a lot faster. To do so, open the track's file Settings.txt in Notepad. It doesn't contain all that many settings, but you can simply copy settings from Data\Settings.dat to the track's own Settings.txt, and the game will then use those instead. Specific settings you would be looking for are things like acceleration, maxSpeed, rotationAcceleration and maxRotationSpeed. There are also lots of other settings, I'd love to see if you can make a really different experience from what Proun already is!

Hint #7: Getting a mesh with for your cable in 3D Studio MAX

You can create a mesh for the cable to see it's exact thickness in 3dsmax as well. This is very useful to see whether your objects align with the cable. To do so, create a Circle with radius 0.4. Then select the main line, and go to the Compound objects object category (in the panel on the right of the screen, this can be found in the left-most tab, where you can also create Boxes and such). With the line selected, click Loft. Now click Get shape and select the circle you just made.

Note that the loft object will also be exported with the game, which is pretty slow and kind of inconvenient. Once the track is finished, you can delete your loft object, or turn the standard cable off in Proun, so that you can use your own cable mesh instead. Just set cable_generateMesh to false in the Settings.txt in your track's folder.

Hint #8: Starting with the cable

You can approach designing your tracks in many ways, of course, but I found that you get the smoothest gameplay if you first lay out the cable, then play/tweak a couple of times to make it a smooth ride, and only then place the obstacles along the spline. It is pretty difficult to get a smooth cable if you first lay out your obstacles and then try to move your line towards them, so going the other way around is easier to get right, in my experience.

Oooh , nice, cant wait to see what people come up with. Mabye a 'ghost' boost?

Also, can you add your own tracks to the game? (As in music)

Added hint #2!

Yeah I saw that option, and I was wondering, we may need some additional description here at some point.
Whether they ask a friend or choose a creative commons music, people may need to display credits for the songs they share with their tracks.
For example it could be

And that would appear in a smaller font beneath the track name in the track selection screen

Added a new tip, about sun rays this time!

@Lemo: That's a good idea, but I cannot change that anymore, since lots of people have already installed the game and I cannot force them to apply a patch. However, you can add a it to the track's name, or add it to the background image of the track in the menu.

Just added another tip, this time about using HDRI objects, which can be used to create some cool colour/lighting effects in the game.

Added another tip! This time about looking around your map in-game using the debug window.

Added a tip about how to change the gameplay of the existing tracks. You can even distribute modified versions of the original tracks 1-4! Just don't do this for Track05, since that one is for paying users only.

I added an explanation I typed elsewhere to the list, about creating your own cablemesh in 3dsmax.
