Hello all guys! I have created the largest terrain possible in LE which is 4096x4096x10m (in fact, by modifying sbx with notepad, u can make it even larger). On distant locations (relative to origin), I see artifacts on shadow maps and UV assignments as well as geometry degredation which I believe all due to floating point precision loss. Here is the related video, although you can check it out yourself by creating a terrain in Editor. Parts of terrain at locations (0,0,0), (7500,0,7500), (15000,0,15000), (20480,0,20480). : ftp://81.214.87.33/ user : katron pass : katron2012 file : "LE 4096x10m map precision problem - DIVX.avi" What are your comments on this issue ? (One possible dirty solution : I can move the terrain and objects on it instead of moving the cam ) PS: I encountered precision problem on my previous job, where we were implementing a google earth clone 3D app. We were visualising the whole earth along with a tiny house or road sign in the same scene. We solved the issue by utilizing "camera relative rendering" & "using double precision math on vector calculations taking place on cpu" & "enabling consistent floating point mode on direct3D".
