I want to add that I am using your prefab building to construct a structure on my server's Middle Ages themed area. I was doing some adjustment and had to remove some sections to make the wooden wall and some floors shorter. I noticed you used half round pieces and shrunk them down. At first, I did not understand why, then I noticed that it leaves a seam in the floor or wall that looks like a log on the wall but not as much on the floor. However if you used flat or rectangles there would be no visible seam. I must say it is a brilliant use of visual effects and compliment you on it. I learned from it the art technique of using the shapes for visual effect not just construction.
Thank you yes I decided to use shapes to get that sort of 3D effect cause just a textures makes things just flat and boring so the more creative you can get with shapes the more interesting and life like building can become
