I want to import obj models, the problem is that i need to activate pos center of the object at "on" in order to see the model. Furthermore i can't export the obj model to a web scene without crash, when it works i have a model with very low textures and i must zoom on the object (finding it with a search and then zoom on it). I meet many difficulties with the manage of 3d models.
My assets is coming from sketchup , and contains 70 000 faces. I have checked the position in sketchup and the model is located at 2000m from the origin,maybe that's the reason why i must check pos_center?
Next, What are the limit and advices to create a scene web? In a project city engine cej, what are the limit in terms of polygon and textures. what kind of model works better ( collada, obj, gdb)? I want to import 3d model from photogrammetry, is it possible or must i cut my model in area 500*500m? Finally is there a way to manage models .citygml? Sorry if i have many questions. Thanks a lot for your help.
