Problem about exporting blend files in 4.3

Hello everyone.I have been using unity for couple of months and I could easily drag and release blend files to the unity. Now there is a problem as many people know :
Blender could not convert the .blend file to FBX file.You need to use Blender 2.45-2.49 or 2.58 and later versions for direct Blender import to work.
My Unity version is 4.3 and Blender version is 2.69 which both are last versions.
I read almost every post about exporting blend files but nothing could help me. I uninstall 4.3 and return 4.2 but the problem is same. I also change blender versions but always for some files it gives this error. It seems that only solution exporting manually in blender and then dragging it. But when i do this it comes with camera inside and other stuffs and also it divide my model into parts. So its give problems about component such as collider etc…(briefly its not the same file as draging to the unity like old way) Also when i export manually the .fbx files has bigger memory than normal.

Long story short i am looking for real solution. How can i export my blend files easily like i used to do. 2 weeks ago there were no problem and now it is. I will be thankfull if anyone can help me about this annoying situation.

Hey, Hatredalper, I was in the same exact situation, and the weirdest part was I could edit in Blender (2.69) and after Unity (4.3.1) imports the changes, everything would be as right as rain. Then I got the bug and it kept recurring and I just couldn’t understand it. I even went as far as rolling back to Blender 2.68.

So after looking around, it turns out that if you save your .blend file in Blender while in Edit Mode, it will throw the error, but in Object Mode, everything will be cool. I have tested this and it works for me, so maybe it will work out for you as well. Let me know how it goes though.

Good luck

Does Blender still have the .FBX export in File/Export? use that since they are usually smaller than .blend files i do the same with Max even though .max import work.

Do the conversion inside blender, it saves the hassle with unity whinging about it and is cheaper storage wise. To do this go to File/Export/Export FBX,

Now last time i used blender it had no FBX import :(, if this is still true, make a folder outside you project folder call it whatever you like(e.g “MyBlenderModels”) and save the .Blend files there.

when you want to edit your .fbx model, open the .blend file for it , do your editing and overwrite the .fbx in your project. thus updating it.

its a little more annoying than just jamming it in the Assets folder but i think i had this problem with 2.56 when it came out, told both Unity and Blender and they blamed each other lol.

Hi, I got the the problem and I think I have figured out the answer, in my case at least. But I just want to share just in case if anyone has the same problem with me.

Apparently the problem occurred if I switch the input preset to other than blender (maya/max). Because when I tested switching back to 2.68, it works. But when I switch the preset to maya, the problem reoccured. So I tried to switch the 2.69 preset back to blender, everything works fine again.
