Thx for your comments!
you use some shader on models?like on that coke can?
No I'm not using any shaders other than some bump mapping on the crate. The coke can is just a very (very) highly detailed model and a texture for the label and one for the metal, so the metal effect is static. I couldn't get environment mapping to work yet.

"Save the planet by destroying garbage"
It wasn't the idea to collect and dispose garbage in the game, but that you have to collect useful things in your environment that the colony can use. Get water, fuel, batteries etc.
And you have to defend the colony against danger. Animals and humans, forces like water masses or toxic gases and other things.
The garbage dispose is not a bad idea though, could make it as a side mission

I would want the player to have to think from the position of those very little humans, what they have to deal with.
It's a position of weakness because of their size, but they make up for it by using current technology on their own level.
A 'flying car' is actually very possible today, it's just very hard to build one that can lift humans. You can buy toy planes and helicopters everywhere now, and they are just using those as their own vehicles. So they have a lot of advantages like that because they're small but can use our technologies and power supplies.

How are you handling AI in Pico10 ?
I don't have any AI in my project yet, it's a physics and graphics prototype so far.
But I have been thinking about how I could have a glider fly by itself. Getting it to fly smoothly and follow routes or get to an appointed location is going to be a big issue. Getting it to work in 3D is way beyond my knowledge right now.
I'm using 3DMax for modelling and the rest are 3DGS-Tools. It took me some time to understand them, but now it works alright.
Does "die Minimenschen" mean something to you all or is this a less known comic?
And would you like to see a game like this in a comic-style or more realistic as it is now?
so long...
