Now about stadiums a little. FIFA stadiums made by EA for FIFA 12, works in FIFA 13 too, but there will need of some improvemants. I try with stadium made by me, but it dont work good. Most of the parts are invisible, and just some of them are visible for a while. I hope it is cous of new way of boundingboxes, I`m sure that ludo will do something about that.
Edit1:
I have imported stadium made by me, but with low quality(not much meshes) and seems to be good, no disapearing, stewards, player benches photographers are moving too, there is a things which are not good(the transperant textures ar not transperant, dont know why), but work. I hope that there will not have a limit of meshes or file size, cous all HQ stadiums will be wasted
. This stadium but in HQ dont work good.
Edit2:
I think that there is no limits of meshes or file size. There is a problem with .b2f files from blender. If thay are .3ds everythings looks good. Thats for now.
