I've been experimenting lately with the idea of creating an entire sim in a CAD program (3DS Max in my case) and importing it into SL. However my tinkering has turned up a couple of weird issues that I was hoping to get clarification on. Firstly: Mesh size restrictions. http://puu.sh/mQj0u/f2488ede03.jpg The image above shows my landscape as it is in 3DS Max. It's seperated into 16, 64m^2 segments, with varying height. Each segment has 2048 tris, for a total of 32,780 tris for the entire thing. However, when attempting to upload to SL, it seems to hard-cap it at 240m^2 (which I cannot change), as seen here. http://puu.sh/mQjqz/2aa3dcff19.jpg All the segments are definitely no larger than 64m^2 in size, so it's not an issue of my creation. Is anyone else aware of this limit? If so, why is it there and is it possible to bypass? As you can see in the image below, taking off the outer segments (to reduce the max size to 192m^2) allows me to upload it at full size. http://puu.sh/mQjvL/2512644511.png Secondly: Land Impact Let's take a look at the Land Impact of my landscape (a single segment of 64m^2 for this). I've set the Physics to follow the "High" mesh, so that avatars can accurately walk on the mesh's surface. The image below shows the mesh's LI at full-size (64m^2), with two different physics settings. http://puu.sh/mQkja/8d06e9f4a5.png Convex Hull, 67 LI. http://puu.sh/mQkkj/74e53d6281.png Prim, 118 LI. And here it is, shrunken to x0.25 (16m^2) original. http://puu.sh/mQkme/4de296085e.png Convex Hull, 25 LI. http://puu.sh/mQknh/e0af0f1953.png Prim, 494 LI. (!!!) The smaller I shrink the mesh from the original size, the more LI is impacted when set to Prim physical type. Here it is at x0.15 size. http://puu.sh/mQkro/5eff9412aa.png Eight hundred and FIFTY Land Impact. So what exactly is going on here? How come, when Prim physics is enabled, the LI is reasonable when scaled to maximum size, but gets ridiculous when shrunk?
