So since I've been able to work out this mesh-loader thing now I have an scene composed of objects going up to thousands. The thing is, I would like to export an scene of it(after I did my own edits of course), with the right object positioning and all that.

Would OBJ be a good format for that? I need to export an scene with no texture data, uv mapping, skeletons, etc. Just need vertexes, normal, and faces, and multiple objects. Looking over the OBJ information on Wikipedia I've been able to make exports of singular objects, but Max seems to just die on me when trying to import a whole scene of it saying "Invalid Vertex Index". It doesn't show this error if I click on import as single mesh... but I don't want to show it as a single mesh, and it seems to just crash anyway. I've been googling about info on the OBJ format but I have some doubts.

My questions are:

• Is this the right way of writing out an OBJ file? (Values are made up, not a real object)

• What's the right way to write out vertex indexes for the face data? Is 0 a valid index, or does it start from 1?

  
  

• Related to the index question, every time I declare a new object using "g <name>", is the vertex index for the face data supposed to start from 0/1 again, or is it an absolute index of the whole file?

  
  

• I guess faces are supposed to be written in the same way I imported them? (as in groups of three, instead of triangle strips)

Oh I got plenty more models now.

My only problem is that I want to export this but I can't really do it properly. I've tried exporting every single mesh as an OBJ, but Max just seems to die on them. The total polygon count is about 1 million.

So I was wondering if there's a more lightweight and easier to write to format than OBJ. Or some program that won't die on importing all these. It's about 3,000 files.

It's just static geometry so no problems. The vectors are already multiplied by the transformation matrix to be in the right positions.

I tried exporting every object in a separate obj file and I can load them on their own, but can't find any options to import them into a single scene in blender or max(and blender seems to have changed his "Import OBJ dir" options in the latest releases). However, appending them all to a single obj file like this doesn't seem valid?

Blender seems to crash due to memory usage when loading it up. Is the file incorrect? I could probably do just fine with something that imports all OBJ files into a single scene tho.

I tried using lib3ds to save it, and while Max just said "Improper file format", blender opened it just fine, even for my 2GB ram. I'm just saving vertices and faces, so I wonder what's the problem with max.

I guess it's solved for now. Thanks.
