Unity 2018.4.5f1- Blender could not convert the .blend file to FBX file.

Question

Hi, I have a big problem: sometimes I cannot save some Blender models from 2.80 version and an error message appears in Unity.

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

I have Unity 2018.4.5f1 version and I don't know what I have to do now, please help.

I dont know if Unity supports blender files but you can export them into a file format it does understand like FBX or Objs (I think Objs are your safest bet as I dont think they require 3rd party software to enable support for them)

Edit

Ok so it does support them providing your version of blender supports exporting to FBX.

So, there may be something in your blender file that is causing the export to fail. Check the list of compatible objects or just use the exporter from within blender.

Thanks for the answer, nevertheless, the problem is not relative to the importing/exporting system from .blend file to .fbx file, but the file .blend itself that which Unity cannot read anymore. Right some $$anonymous$$utes ago, I tried to update the blender software (always 2.80 version) and now every model I create and save, Unity cannot read them. I think that the Unity version I'm using doesn't support the current version of Blender, but the odd thing is that the current version of Unity I'm using has been released almost two months ago ç_ç

I figured that may be the case which is why i said:

" there may be something in your blender file that is causing the export to fail. Check the list of compatible objects or just use the exporter from within blender."

Have you tried exporting it as a more standard file format like an . Obj or exporting it from blender as an FBX ins$$anonymous$$d of asking unity to do it?

p.s. If you have the blender file I am happy to test it/ see if I can make it work but I will be going out in about 20 $$anonymous$$s so wont be able to afterwards.

I found that I had this problem with unity 2020.1.16f1 and blender 2.91 on windows. Posting my fix here in case it helps others.

give the Unity hub and the installed unity.exe "run as administrator" privilege's so that the intermediate files have the permision to be written. Also, verify that blender 2.91 is set as the system default for "open with" on all .blend files.

It's weird that that Unity would need ad$$anonymous$$ permissions.... but this worked. I ran Unity as ad$$anonymous$$, loaded the project. No errors. Closed it, and ran normally, now blender importing works. Thanks.

This question doesnt belong here, go to blender website for this.

It's about Unitys handling of files so it probably does belong here.

I have the 2018 version of Unity... maybe this version doesn't support blender 2.80... anyway, actually i'm exporting models from blender to .fbx files, but in future i'll update unity Thanks a lot for your time.
