Hello ,We are developing racing game, our race track size is big as in case of any race game. We are light mapping the scene, the lightmapp settings area as follows, Precomputed Realtime GI disable. Baked GI Baked resolution is 10 and other default settings. The thing is the lightmapping process takes lot of time to complete its. Its been 28 hours and still haven't passed 7 / 11 with 655 Jobs. We have tried it on different System the time it is taking is almost same time without completing its process First PC Config is, 2.5 GB of video memory/Graphic card 4 GB of Ram Win 7 32 bits. Second PC Config, 2 GB of video memory 8 GB of Ram Win 7 64 bit Macbook Pro, 1 GB of video memory, 6 GB of RAM Yosemite So my question is,is it usual for Lightning to take this much amount of time?
