In the most basic form, for example just using eg cubes to illustrate how to do this, is all that's needed.
1. Create yourself a basic terrain 1000x1000 (Height unknown)
2. Place a cube into scene
3. Create yourself another basic terrain 1000x1000 (Height unknown)
How would I fly the cube out of the first terrain, into space, so going through some clouds and into space, see stars and other planets (If there are some there, which would also allow me to fly too and enter the atmosphere and land and explore) fly to the other terrain and land.
Bare in mind that the terrains used in this example are planets.
Don;t just bid on this simply because you think you can do this.
I have done my research and have lots of questions. If you think you can do this, please make a very small and yet simple example and provide that example.
Failing to add the example will result in your bid being rejected.
I have probably missed out other important factors here already, so if you've any questions please ask. In your bid along with your demo.
I have customize the budget for this simple reason. I know there may be a few scripts here that are in use here as well. Your profile if you bid on this should have clearly other examples of people whom have used Unity3D, since this is an important feature.
The project delivery time for this is not 7 days either, its more like 30 days, since I know a lot of time and patience will be required.
There seems to be some confusion here with some people basically saying they wont make a demo with out getting the project, if this is your way of telling me this, then you'll be removed. I don't take kindly to being told what to do.
You don't need to know my skillset. I am the one looking for the programmer. I have made it quite clear what I am looking for, if you can't do this don't bid.
I need to make this extremely clear. If you send me a demo, DO NOT tell me that you created the demo if you've used someone else's asset files and then try and claim that these are your files. I have gone through most of the asset store files from Unity and have studied most of them. 2 people have so far said they created the work themselves only to be caught out. If you use assets that aren't yours I will report you for theft. I will also advise Unity and also the asset store creator of the asset you're claiming as yours.
