Problem with Better DAE exporter (Blender)

I have no idea (sorry) but here’s what I could gleam from the error posted:

It seems it cannot read the animation (action) from AnimData (likely where animations are stored in the data object) because the animation (action) is read only. Maybe try launching Blender as an administrator? Most times when I have read only errors, running as an administrator generally fixes it (if you are on Windows. For Linux you could try running blender using sudo, and I have no idea for MacOS)

Yeah, I have no idea on what is causing the problem.

I googled up a bunch of stuff (like "Blender read only export" and "Blender read only actions") and the only things that came up even somewhat related were FBX exports to Unity (which really does not help, since they're talking about the exported .fbx file, not actually exporting from Blender).

Hopefully someone else knows, because honestly I'm completely stumped on what could be causing the problem.

Yes, that is what i get from error too. Most confusing about this is fact that no one of my animations is called action one is Start and one is Process. It must be something deeper, more internal, less visible to mere mortals like us. I don't think read-only attribute have something common with Windows permissions because Blender keep whole structure inside one file, Windows permissions have no power here.

Can you upload your Blender file or a modified version if you are under NDA.

You tried to delete and reinstall Better Collada exporter?....maybe this will help.

ps. Uh, is google drive against rules ? I swear I sent this posted this before. Do moderators deleted it or it is problem with my internet browser(another one) ?

There is nothing against the rules posting google drive links. I do not think any of the moderators would delete the post (or at least, I haven’t and wouldn’t). It might be your browser, or maybe the server had some problem adding the post?

Nope. Although some file hosting sites can be suspiciously iffy there are no rules on what services to actually use. I'd say google drive is reasonably fine, though in many cases github might be preferable. But again. no rules against any.

Well, I was able to successfully export it to a .dae file using Blender 2.79 (on Windows). I looked through everything and I didn't see anything that looked it could be causing the issue. I'm not sure what the problem is, but it appears it may not be the blender file, but rather something else (or my computer somehow worked around the issue).

PS: Nice model! I like the ascetic and animations!

Well, I just tried those export settings, and it gives me the same error. But I turns out I forgot to press the export animation tab, so I was exporting without animations. It appears exporting with animations gives the error, no matter the settings.

After some looking, I think I've figured out the problem. One of your animations (Start) does not have save this data block even if it has no users (the F button beside the number of instances) and that seems to be causing the issue. It appears all of your animations have to be force saved in order to export.

Here's a picture showing what the animation(s) should look like (with the F button highlighted):

Once all of the animations had save this data block even if it has no users, I was able to export with the settings above.

Side note: Whenever I've exported with Apply Modifiers I've found it does not export my animations in the .dae file due to the Armature modifier being applied. If your exported file does not have animations, you'll probably want to try exporting with Apply Modifiers disabled/unchecked.

This might be a necro post, but I have this exact problem. I'm using Blender 2.79b, Godot 3.4.2, and Linux Mint.

The solution for me is: besides toggling the F to save this data block even if it has no users of each animation in the NLA Editor, I also have to press the lock button beside each animation to be unlocked. By default, animations are locked (I dunno why) and this makes animation as read-only. Unlocked and toggled F worked.

Hope this helps whoever stumbles on this post. Carry on.
