Waiting for the game I'm currently experimenting some trials to creat 3D temple ans pillars.
The first trial will consist of using a thermal saw and polystyren (free and ecological)
First cut a plank of polystyren and use the wastes to sculpt pillars and stones
Using Milliput and textured rolling pin to create a destroyed greek floor
Need to paint it better, but it's quite interesting to be able to make quick decor for low budget O:)
And references for textured roll :
