Ok, here is my entry , and I decided to do an environment because I love doing it
I wanted to use somehow more curvy shapes (as retro sci-fi suggests), but poly limit is a serious issue Firstly, I thougth of a level where 700 tris would be visible in camera view (that would let me do some more curves), but eventually fiting all geometry into 700 tris seemed more challenging and interesting.
I got 702 tris (sorry, 2 more, I hope u will forgive me ). All textures, except for Sky/Space, have 16 color palette.
There are no other channels beside diffuse and opacity because the game that would need such geometry restrictions, unfortunately, could not dream about bumps for level textures (I quess actually this would fit DS).
Total image pixel space used in level take less than 512x512.
Lightning is done with manually assigned vertex colors.
I attached some images (in several posts), but since I did some animated textures in the level, you can download 2MB ziped video:(http://www.psychosphere.in/pics/vlad/Retro_SciFi_Vlad.zip)
Good luck everyone, ur works r comming out really cool:thumbsup: I am eager to see them finished!
