Hello I am trying to make my own interior base, at the very beginning I ran into this problem. I created the new, empty cell, Open it in the rendering window, I select the Object, form the World Objects- Static- Interiors I move the object to the rendering screen and i get error message MODELS: VltHallMidQtr : has a envmap which is not a cubemap which will cause D3D errors. it is an examlpe message, I get the same with all Objects, They doesnt appear in the rendering window, Any suggestion what I am doing wrong? In the videos what I watched, They did not set up anything before the new cell, just move into the rendering window and it appers for them, for me nothing. ( tried with already exisiting interior cell, what used the same static world objects like what I would like to do, I also can't make anything appear what I add to them/ Can someone help me please ?
