I am new in Outerra and I'm not a programer. I am just a enthusiastic to build scenarios and drive inside them. But I want to share my experience to use FBX importer.
I did the passes in the video in youtube using the FBX importer and I had the same issues is quoted here. I exported the models from Sketchup (I use the Sketchup 2014) and I tried to import by FBX importer. The first, I couldn't even export a .fbx to sketchup, because it only export the textures, but it don't create a .fbx archive. Time ago I was trying to use the Unity platform and there I found the same problem. But there I used to export a .dae archive and then I converted it in .fbx using the program FBX Converter Tool. I did the same here and it ran. So, I export a .dae archive and I convert to .fbx using this tool.
When I export the first time, my archives were in a big scale, missing some walls and with no texture. The texture I solved only using the Photoshop to convert the .jpg archives into .dds archives (I noted the images must be the pixels size multiple of four to work) and pasting in a folder created in Outerra directory. The scale was more difficult because I thought all models in sketchup were in a true scale. But I noted that they weren't this form. So, in each model, I saw the approximate scale that the models needs to have the true scale, decrease or increase in sketchup archive and I export after this.
The missing walls happened because I exported with the standard options. In dialog box, I had many options to mark, and the only marked is "Export texture maps". I tried to mark all options and export, but the FBX Importer couldn't import the result archive. So I tried many combinations until I noted that the option "Export Edges" creates this import issue in FBX Importer. So, marking all the anothers options except "Export Edges" solved my problems with the missing walls and now I can export any sketchup form to Outerra.
I hope it helps!
I had another problem. A specific model crashes the Outerra when the camera is near to it. Independently the form I reach this model, always the Outerra craches.
Now I'd like to know how I can put the specific types of models in a folder, because all my imports are independents in Outerra menu. With a large number of models, is difficult to navegate in menu.
