Yet Another Blender Egg Exporter (YABEE)

ninth · July 7, 2011, 11:09am

coppertop, fixed UV image bug. I interpreted UV image as the texture, but UV image don’t have a flag about the texture’s type - i forgot about it.
Also added EXPORT_UV_IMAGE_AS_TEXTURE constant. To disable interpreting UV image as the texture set it to False.
I’ll add the ‘different files’ feature in next revision - it’s not too hard. )

drahun can you run Blender from console and inserted here the error message from console?

@Ninth

Thanks, that’s great .

I run blender from command prompt. I try export animated model with the script. This the report:
read blend: D:\test-boks.blend
Traceback (most recent call last):

Well? I am not sure if it’s what you want to know.

Hm, look like an armature hasn’t any bones in the bone dict. What kind of bones type do you use?
---- edit
Ah, no, i was wrong. Error talk me, that object in the Armature modifier == None. Please, check it.

drahun · July 11, 2011, 1:06am

Ah, no, i was wrong. Error talk me, that object in the Armature modifier == None. Please, check it.

You were right. After I check that, I successfully export the model. The texture, the animation, play nice in panda.

can’t wait the script possible export more complex from blender.

Update. Rev 10.
Changes:

Models that are attached directly to bone without any modifiers are now exported as part of an animated mesh
[Attaching to Joint)
First UV channel is now stored without name to use as default
Auto-creating subdirs if not exists while writing egg file
Copying texture images in the specified subdir, relative to the EGG file (not fully tested, may contain bugs - check console output)
Recording the animation in separate files
Setting the number of sign after point for store in the file

Good progress.
Any plans for glow/gloss/normal/parallax maps support? And Im not sure if it already supports Empty objects?

ninth · July 14, 2011, 7:50am

Yes, i’ll plan to work with textures type

Any unsupported (including Empty) objects are exported as empty group with transforms.

drahun · July 14, 2011, 12:05pm

I try to export a character with a bit complex polygon but no armature using YABEE rev 10, and got this: IndexError: tuple index out of range
What’s happened? I try with rev 7 and successfully.

ninth · July 14, 2011, 1:07pm

Please, insert here full error text from console.

It’s not rev 10. Try to download the script again, and fully replace old script.

hawginsck · July 18, 2011, 5:42pm

will this work with blender 2.58? I may be using it wrong because when i run the script I get no errors but nothing is exported to my specified location. I’ll keep on trying in the meantime. thank you

ninth · July 18, 2011, 6:56pm

It’s should work with 2.58.
If you used last revision (10), then you may check the console. The script should display the full path where he writed file: “WRITE main EGG to …”
Also it can be a problem with permissions to the output folder.
You can specify relative path to output egg: ‘./my_file.egg’/ In this case script should write file to the user’s home directory, for example ‘C:\Documents and settings\user_name\my_file.egg’ for XP/2000 or ‘/home/user_name/my_file.egg’ for linux.
And lastly, if you set ANIM_ONLY = True and you have no animated model, then there is nothing to write )

hawginsck · July 18, 2011, 10:07pm

works like a charm, I had forgotten to select the object and changed the location to a more sense making one. Thank you very much !

j.edgar · July 27, 2011, 12:59pm

I can’t seem to get yabee 7 or 10 to install in Blender 2.58. If I place it in my addons folder and use ctrl-alt-u it doesn’t show up in the list. If I manually install it I get no error warnings but it doesn’t appear in my export dialog.

I would just go back to Blender 2.4x and use chicken but it’s too deprecated for my current project. Also, using the X format and converting through Panda works but the file size and computational expense makes that method impractical when dealing with complex models.

ninth · July 27, 2011, 3:06pm

See instructions in first post. I do not do the installation / integration as I continue to make changes to the script.

j.edgar · July 29, 2011, 10:46pm

Ninth, would you have any objections to me posting a temporary gui and installer for Yabee rev 10? I made it for my own personal use but I thought others as lazy as myself might be interested.

sukiwater · July 31, 2011, 12:11am

Quick Question: How do we actually use this?
I am a complete newbie and I have absolutely no Blender .egg exporting/script using knowledge in Blender.

ninth · July 31, 2011, 4:27am

j.edgar, You are free to make any changes and publish them

sukiwater, script does not require installation. Just open it in th Blender’s text editor and run them
