Hello XGhost
You made several concept art and it looks promessing. I like the yellow barrier with the flickering light. It will be very cool ingame. A bit like the stop sign in the Old mine.
For following guidelines 2 it's a good idea
You probably know now that you need tons of documentation (photos, pictures, etc). But you should be aware of some problems with guidelines 2. They are designed for the new rendering pipeline (> 0.8.1). This pipeline allow several cool things like 100% dynamic lighting etc. However it's still WIP and there is several things that might change. If you want to join us in our quest you're welcome but it might requires to remake several time your track (I have already made maybe 10 versions of harvest :P).
I suggest to take only advice from guidelines 2 and avoid for the moment the new pipeline. It's too instable for the moment. Also these guidelines are also WIP. So you if you found some issues or misunderstanding please write us.
You can try to make your own textures. I have also a texture pack stater kit if you have don't have a tablet to hand paint them.
I should write a tutorial about how to make an object for the next gen pipeline. Maybe a video tutorial.
[edit]About fictional location: These locations are created for core tracks (tracks that will be included by default in the game). So as addons maker you are of course free to choose what you want. But be aware that we will refuse tracks that don't fit into our graphical style and universe to be included in the core package.
Currently sadly we don't have logos for these companies
. But the idea is to give things to inspire people that want to create a track. For instance your track seems to be in a forest with trees, etc. If you read the location list there is currently 3 locations that might fit in this description.
The Jerico Natural Park
A small mountain village in Switzerland: Berglidorf
A small village in tundra in Russia: Tushka
So you choose one of this location for instance the Jerico Natural Park. It's located in United States of America. So you can look for
reference about the welcome sign of a natural park in USA.You can include this sign in the track. Or a reference to this park (Jerico Natural Park entrance in 50km).
Look how a real sign in USA looks and adapt it to our universe.
During road works there is probably signs like road closed, detour signs, etc. Also it's very easy to you since you just have to see how they look in USA. Probably these heavy machines need fuel. So there is probably a
tank truck. We have a fuel company called tuxel so this truck should have the name Tuxel printed on the tank with maybe a slogan. Also the guidelines says that the universe should be caricatural. So you should choose a truck that is a classical cliché about American truck.
That's designed to help you not to add more constraints. Of course I assumed that you have choose to put your track in the Jerico Natural Park. But if you choose to put it in Switzerland well you do the same process but with Switzerland related stuff.
