I've reworked the model : a little bonus : As you suggested, Enrique, I've added the bevel, on every blocks, which raises the faces count to 4371 ! Isn't it too much, even for a wonder ? Could you give me the faces count of the Persian hanging gardens as a comparison ? 4 questions : -For the texture, it's still my personal texture, used in basic mosaic mode. It looks good to me this way, but I guess for the game we need the texture to be UV mapped, right ? If yes, I have quite a lot of separate elements here and I imagine it's going to be rather messy to manage in the UV mapping window... What do you think ? What technique do you suggest for the seams and the setting of the texture for so many separate meshes ? Oh, and the exterior circle of my Stonehenge is an array of one row, so, for now, I can't apply customizations on these stones. They are all the same. Next step, I apply the array for good and will make some random profiles to those stones. -As requested for topological reasons of the game, I have to make the mass of the structure go deep in the ground. How much should I count under the ground ? The equivalent of 2 meters ? -I'd love to import a wonder from the game, but I didn't found the folder where are the files in the svn on my computer. Can you guide me? Does the file include the texture image in itself or is it separated? -For this structure, do I need to make a ground (soil, grass...) mesh/texture, or do I just make the stones ? Sorry, lots of questions!
