Thanks for this! Definitely useful!

 

Thanks!

 

Thank you for this! Really useful. Is there a way to export selected?

 

Thanks for sharing.

 

Glad this is useful! Both to you guys and to me haha.

Not yet. I plan on adding it though .

Changes since release, new version coming soon
- Material Instances are now named by instance ID (Material Instance Percautions option)
- Material colors are now added into the .mtl file
- Materials can now be named by texture (useful if all your materials are named Diffuse somehow)

 

Excellent, this will come in handy, seems to be the statement made by most, but what can ya say.

I'd really love the export selected option as well.

well done!

 

New version uploaded

Added features :
-Use texture name as material name
-Material instance precautions
-Material specular and diffuse colors

Feedback as always is appreciated

 

Thank you,

If you add 2 lines, everybody could use it on all platform.

#if UNITY_EDITOR

#endif

 

Where exactly would these be added?

 

#if UNITY_EDITOR
using UnityEngine;
using UnityEditor;
using System.Collections;
using System.Collections.Generic;

........

System.IO.File.WriteAllText (exportFolder + "/" + exportName + ".obj",sb.ToString ());
System.IO.File.WriteAllText (exportFolder + "/" + exportName + ".mtl",sb2.ToString ());
}

}
#endif

 

Thank you . This has now been added.

NEW UPDATE
-Fixed mirroring
-Added menfou's suggestion

ANOTHER NEW UPDATE
-Added split modes : None, By Material, By Mesh, By Submesh (None is kind of weird at the moment, works in 3dsmax if "Import As Single Mesh" is checked)
-Added a check to see if "_Color" property exists
-Added version number on the wizard

Download in first post as always

 

ANOTHER UPDATE
-OBJ Comment line, to add a comment at the beginning of the file
-Export Selected [finally? ] has been added
-Added texture scale (-s) in materials files for supported modelers
-Added the clamp parameter if a texture is clamped (-clamp on)

TIP : Want to export one object and have it centered when you import it to your 3D application? Untick "Apply Position"

TIP : Creating materials programatically and they all end up being named "Diffuse", or similar? Use "Mat Name From Texture Name" option

Download is in first post as always

 

This is relevant to my interests

 

Interesting.

 

NEW UPDATE
-Added progress bar. It's helpful on large exports if you are to switch to another process

-Added a save file dialog when you click 'Export', No more manual path typing in!
-Moved around parameters order.

FIRST POST CHANGES
-Added documentation of parameter names

In first post, as always

 

There was a order of transform operations error that was causing the bug with warped objects. This has now been fixed!

This is when I realized it was a major issue:

>Scene in unity : http://i.imgur.com/WOauYlw.png

New feature as well : Transparency is now extracted from the material color!

The first post has now been updated with the fix

 

This will be on the asset store soon. Free of charge.

Does anybody have any suggestions before I upload it there?

 

Yes, dont make me have to get unity 4.6

Thanks for working on this its very useful

 

Well I just realized the progress bar is broken. Gah

 

I just realised I have to have 4.6 to get it from the asset store. NOOOOOOOOOOOooooooooooooooo!

 

It's not me who sets that unfortunately. =c

 

I thought it was based on the version of unity you use to package and submit it to the asset store with, NVM when its out of beta I will upgrade unity anyway in the meantime I can use the supllied script.

Good work.

 

Soon I will do an update anyways and put it on the thread here as a unitypackage and script

 

Hey! This looks great, but I am not able to find the "export" under file. Is it anything i have missed? I downloaded and imported via Asset Store.

 

Fresh download and import for me shows it in the File section. You may want to try reimporting the folder the script is in or refreshing it.

 

Thanks for this.

 

Working on another update with skinned meshes included this time. As well as a nicer UI and most likely some more parameters for MTL

 

Great work.

 

Awesome. Can't wait.

 

Forgive me for my stupidity if this has already been answered. Can this be made to work at runtime? It seems like it could be extremely useful for a number of applications.

 

It can with some code modifications, yes.

 

Thank you for giving us something that works with Unity 5.

 

I've found tons of usage for this, and it's fantastic!

 

Thank you all for your comments! I will try to update/improve this soon

 

Hello,
This tool only exports objects correct?.
Does anybody knows on how to export prefabs, so that it can be worked on blender for example?.
Thanks.

 

This can export the entire scene at once. You could load in a prefab, select it, export selected only, then re-import the needed things.

 

I can't export the textures
it only exports the obj and mtl files

 

What is the texture format of these texture files?

 

jpeg and png

 

Can it export UV1 and UV2? Could be great to export the Unity-generated UVs and bake lightmaps externally in Modo or Maya

 

Unfortunately the OBJ format only supports 1 UV channel due to it's design.

 

I tried your script because we have a lot of work which requires to export Prefabs from Unity and unfortunatly it doesn't work: the OBJ comes empty in 3dsMax, it just says "nothing found to import". I got the same result either I try with or without textures.

Is there something I'm missing? Can you help me about it? It would save me and my teammates a lot of hours of work and we'll be infinitely grateful, and as I'm a graphic artist my knowledge of scripting is below the absolute zero...

The objects are mostly FBX or Prefabs and textures are TGA. I'm using unity 5.1.1f1 if it helps.

 

Hmm maybe something broke with Unity 5, seeing as how others are saying the same thing D: . I'll take a look and see if something's up with the script.

 

The export worked (image 1), but I lost the control the "control points" (image 2) I had on the file. I

s there any way to preserve it on the export?

 

OBJ is a fairly basic format, which doesn't support custom things like control points.

Hi, since i wouldn't touch the current code with a 20ft pole, and, since I've had an interest in updating this project, I am hereby providing Version 2.0. Could you please make an export attempt with this?
(NOTE : Not compatible with version 1.0!)

 

Great, I'm gonna try this!

 

Just updated the first post with version 2.0, enjoy! Also submitted to asset store for review.

 

Version 2.01 has been released:
Added the ability to export bump maps / specular maps. General fixes and improvements.

 

Wow, I was looking for the ObjExporter from the wiki and have found this, which is great. Thank you!
