As long as we do not have such a system i propose that we just keep with what we have and do a bit of effort to get the most apparent issues solved. Blindly replacing what we have with something new and then fixing afterwards whatever shows up as bug or missing feature is imho not a feasible option.

Agree, and for this reason I think its not sensible to make replacing existing collada export an initial target for including this add-on.

Some facts:

  • If we are kicking out the current Collada module now, then Blender has no Collada Importer any more.
  • Juan's Importer is not ready for Blender yet (he said so himself, not my words)

@Juan Linietsky (reduz), no decisions have been made, and I only ask for evidence - to check code works before including it in releases is not speculation, its the bare minimum if you propose to replace existing code.
If many users are using this exporter successfully, where are they? can you point to projects where they document to use this? blog posts, tutorials recommending this?

Well guys, let's do the following. Feel free to keep evaluating my importer, but after thinking this well I realized it's too early to submit it to you for adoption.
Even though I believe I have ample experience with this format, It's difficult for me to substance my claims so it only results in meaningless arguments.

We can call it how we like "Collada (realtime)" or "Collada (game-engines)" ...
Fix obvious bugs and include it as an option.
I don't see this as being especially conservative, on the other hand if you propose this replaces the existing exporter.
Then it makes sense to take care that this doesnt break existing use cases (SecondLife for eg).

@juan ferrer (juan): From my tests yesterday and today i can not confirm that your exporter "exports every little bit of information supported by the spec". No offense intended here, just clarifying the statements based on experiments :) thanks

Oh and on addition to that, does Blender exporter support proper triangulation of meshes so TBN is correct and shown like in Blender viweport?
I also added a lot of internal state checking to my exporter to warn users when something will not be exported as they expect.. in order for them to fix it instead of silently failing. Examples of this are more than one armature assigned, unassigned weights, empty animations, etc (check all the calls to report in the code).

I added 3 blend files with some tests in them. All blend files use

  • layer 0 for the original
  • layer 5 for the back import of the blender exporter
  • layer 15 for the back import of the godot exporter

For now i can not tell if one is better than the other. I see issues with both systems.
But i do not yet see where the one is a total broken system where the other shines with perfection.
I also know that blender' exporter has a lot of issues but i do not see where it breaks the Collada specifications.

Again to avoid misunderstandings, we can work together on fixing and changing whatever is needed, but I will only spend my time on this if:

Campbell, with all due respect, I think your way of thinking is too conservative and missing the point. All this situation is happening because Ton complained publicly that game engines all depend from Autodesk and closed formats (FBX). We already know all other engines use FBX and have limited (or if any) support for Collada.

May I ask why Collada and not OpenGEX ?

@juan ferrer (juan): I am sure you have a set of cases where the Blender exporter fails but your exporter does it correct. Is it possible to add some blend files here with such examples? That would be super cool and speed up testing a lot.

Gaia, I'm sorry, I don't have the time or resources to do that

@Gaia I never really made any effort optimizing individual indices for each type of components, as this feature of Collada is not portable between DCCs (which use different approaches to smoothing), and also unsupported on 3D hardware (thus, useless for game engines).

About the name of the plugin, what about naming it "Collada4Games"? to make it very clear that the plugin intends to write files readable by game engines, not other DCCs.

Cambell, I will submit a new version soon (as this one is really outdated). I have some questions.

Guys, do you really care about this or not?
I'm still developing the plugin and I'm almost done with support for morphs.

Sorry for asking, but where do I find access to the addons project VCS? I can't find much information in https://developer.blender.org

I'm fine with this. If it's in contrib I can imagine i can tell users to go use that one and report issues again that one, right?
