Blender > Unity Rotation Fix

BRILLIANT!!! This was a problem I planned on tackling latter in development and I stumbled upon this. Thanks so much! BTW it works with Blender 2.7 & Unity 4.5.1f3

 

This is very helpful and a huge time saver! I just tested it with Blender 2.7.1 and it worked great.

 

I love you.

 

I have a question. If I used this addon on a humanoid mesh that has an armature and animation in blender will not the animations be messed up. i.e if the character has a walking animation will he then not be walking up a wall in blender and in unity will he not be facing the right direction until you play an animation then be walking either away from the front view or up the unity global y axis?

 

If you converting existing character that is rigged, you should only apply fix on armature, mesh should have no additional rotation. Animations works fine, and rig should be updated only if you use drivers.

 

This is really helpful, thanks.

 

Does this thread deal with this kind of problem that occurs to me while bringing an FBX from Blender to Unity?
I am not really sure. It would be nice if somebody could tell me if that is actualy the problem that is being discussed here.
Thank you.

 

No, I don't think so. This plugin fixes rotation problem when your model lies on its face when imported from Blender to Unity. In Blender -Y axis is forward, script brute forces it to be +Z like in Unity.

 

Great add-on. Saved me tons of time. Thank you.

 

It would be sure nice if this issue was resolved in Unity; but, here is another little workaround which some may like:

1. Open model in Blender.
2. Add empty object at origin.
3. Save as .blend file.
4. Import into Unity; rotation all good but redundant empty game object in scene. Delete, save as prefab

 

I still prefer the script I posted on the previous page.
But indeed it would be nice if Unity implemented a fix for something as silly as this issue.
Or at least post a reason why it is not being fixed.

 

This is perfect, just what I was looking for. Thanks for your work.

 

I thought I was going mad till I did a search and found this utility. Thank you for sharing it!

 

This is perfect, thank you!

 

Wondering if anybody can help.
I'm not a blender user and just a Unity beginner.
I have installed, enabled and can see MISC, Unity Tools

BUT

After opening the blender file that I want to modify the MISC tab disappears.

I can still see that the add-on is installed and enabled but there doesn't seem to be any way to get to it.

I tried opening the script in the text editor and RUN SCRIPT but that didn't do anything for my either.

Any help would be most appreciated - trying to fix this Unity/Blender issue is just horrible!

 

could you walk me through the installation proccess, i dont seem to have any of the tabs or buttons youre mentioning in your instructions

 

oH it works but i lost the mirrored work.

 

Hey!
I absolutely love the add-on, but I've got a little problem with it:
I used it in blender 2.6ish version and it worked properly, but since I updated to 2.74 it just won't show. I even downloaded and reinstalled the file, and it gets shown as an add-on in the user-preferences, but it just won't show up in the Tool Shelf.

 

Working with Blender 2.76b. Mirgar, thanks for this!

 

Thanks. You saved me from a big headache.

 

Thanks I was about to lose my mind trying to get the rotations right

 

thank you, thank you, thank you, thank you, thank you, thank you, thank you! I can finally use Blender instead of expensive Maya! xD

 

Script is working well for me, thanks very much for sharing.

 

Thanks dude! Blender should add this add-on to their offical release lol
I can't believe this problem still exists after so many years though, thank you Unity : \

 

Hey guys,
can't find the menu point either :/
Can anybody provide a simple screenhot maybe ?

 

Had the same problem myself in Blender 2.78. After you install the plugin, make sure that there's a checkmark in the box for it under "Addons -> Object -> Object: Unity Tools" in user preferences AND THEN SAVE YOUR PREFS. If you don't save the prefs, it will vanish when you close Blender.

Once you do that, it should be on the vertical toolbar under "Misc" at the far left of the Blender UI (it gets its own tab, among those which sit at the extreme far left of the Blender window).

 

I am getting a Error message: “expected an indented block” on blender 2.76 osx, when trying to enable the addon.

 

Ha, thanks for this awesome addon, my Blender => Unity3D imports using FBX aren't screwed anymore, thanks men.
(Using Blender 2.78a and Unity3D 5.5.0f3)

 

I've found the solution to this is actually really easy. I'm not sure if this works 100% of the time, but if you rotate your model by -90 degrees on X in Blender, apply rotations and rotate by 90 on X again it will appear correct in Blender and by 0 rotations in Unity. It takes 2 seconds to do, I haven't found the need for an addon or anything to solve this.

 

This script fixes the local axis directions for me, but my objects end up facing backwards when I import into Unity. (local forward is opposite of global forward) Is this expected or am I doing something wrong? I guess it may not matter that much since I'll probably rotate the objects when placing them in scenes anyway.

 

I know this is an old thread but wanted to say thank you very much (@Mirgar and @Freezy) for this! Saved me a lot of strained brain cells.

Those who can't find the tool after installing the add-on, press T, and click misc tab. It is under Unity Tools. Simple rotation works perfectly for me. If you are having issues with scales (E.g. having random scales etc..), when exporting as FBX, be sure to Un-select the little button next to "Scale". If you mouse over it, it will say "Scale all data according to current blender..."

 

It is really weird that Unity still has not fixed this issue XD

 

Unfortunately didn't work for me (Blender 2.78). Perhaps doing something wrong.

Here are things I tried (for Unity_tools.py):

CASE 1:

1. select object in object mode
2. click "Simple rotation fix" / "Full rotation fix"
3. nothing happens!

CASE 2:

1. run through Python console bpy.ops.object.unity_rotation_fix_x()
2. getting error
   RuntimeError: Operator bpy.ops.object.unity_rotation_fix_x.poll() failed, context is incorrect

 

I have no idea what your script does, but it does work ! Thanks a lot ! You're saving me much time.

 

Doesnt work in unity 2017.3 with 2.79 blender

 

I just tested it moment ago with newest versions of both Blender and Unity and it works correctly. Are you sure you're exporting your model correctly?

 

wait a moment. so we should export the object to .fbx? i think it will fixed how unity synchronize with blender's axis

 

I mainly use .fbx format but exporting using collada produces the same results for me too. Same with saving .blend directly in project's assets folder. If you're still having issues, can you describe how you export your models into your project?

 

I've linked Mirgar's Rotation fix for years as the GOTO but these days its not required as Blender can now successfully export with proper rotation.

https://answers.unity.com/questions...to-un.html?childToView=1458751#answer-1458751

In light of recent discussions I should mention that this is for FBX export options, as some people like to use Blend directly in which case the fix is still awesome.

 

for Blender 1.80 BETA here's the working fix

 

I just updated to blender 2.79b and It seems like the scale problem is, well, no longer a problem. However, I still have to use that tool for rotations for grouped objects. It works fine if the model is one mesh and no grouping.

 

Thank you, this has solved the problem I was having.

 

Thank you so much!!! It was so annoying to have to tweak rotation after importing literally ANYTHING from unity! I can confirm that using the "simple rotation fix" works perfectly on blender 2.79.

 

I am so glad this page is still coming up when searching blender. This helped so much.

 

it’s a life saver

 

Good addon, I recommend

 

Heya guys!

Here you have an updated version of the addon for Blender 2.8 Release Candidate

 

Thanks a bunch! I had to delete the old add on and then install this one, otherwise it didn't seem to register the change in Blender 2.80

 

Someone messed up here. Everything is upside down.
Edit: Tried fixing it. No clue what to do. Didn't work

 

Fixed the issue for the latest Blender 2.8 stable release. For the guys here who downloaded Unity Tools 280RC.rar above, you just need to reverse the rotation operations along the X-axis. Open the addon using a text editor and change the following code:

Code (CSharp):

1. value = -1.5708

to

Code (CSharp):

1. value = 1.5708

and then the other values

Code (CSharp):

1. value = 1.5708

to

Code (CSharp):

1. value = -1.5708

Hopefully the author uploads an update.
