Some people have issues with FBX, but when it's supported correctly it's extremely reliable. Sony started it, then abandoned it to open source caretakers, who then made 'bits' of it commercial IIRC. I avoid anything that only exports DAE, it's buggy and unpredictable. What are the pros and cons of any relevant file types for that matter? What do any of them do differently? TLDR: What distinguishes the different file types? What makes some better for some things and some better for others? Is one just better than all of them in every way, if so then why?Īctual TLDR: What do different 3D model formats do differently? What are there pros and cons of each one?įBX and Collada DAE are both full scene formats, there's no point in comparing them with obj. (Unless everyone uses FBX because everyone's been told to use FBX.) So anyway, why does everyone use FBX and what are it's advantages? I know OBJ must have some disadvantages, but so far it's worked the best for me. This all got very confusing but I walked away thinking there must be some reason everyone recommends FBX. However, when I took the OBJ file and converted it to FBX via Blender it worker flawlessly, unlike the OBJ to FBX via FBX converter. Even the ones that were other file types then converted to FBX. I also noticed that FBX had scaling issues when imported into Unity. I then converted all these files into FBX using auto desk FBX converter 2013 (because someone told me that Unity just converts non-FBX files into FBX anyway.) Now the results showed that the OBJ file that was converted to FBX was still smaller than the other formats converted to FBX (how ever the standard OBJ file was still the smallest.) Note that this was a small, texture-less, simple model exported from Sketch Up.

Well I did some testing on a simple model from Google Sketch Up which revealed that out of all the file type I tested (OBJ, DAE, and FBX) that FBX had the biggest file size followed by DAE and then OBJ with the smallest file size.

So I've seen one or two threads on which file type people should use and most people have said to use FBX.
