We require a .blend file to reproduce the issue.

This will need a bit of fix-er-uping in the install_deps.sh to apply the patch after downloading the sources, though.

I think best is to update https://developer.blender.org/diffusion/B/browse/master/build_files/build_environment/patches/opencollada.diff with any patch we deem necessary to keep things rolling. This seems to be the way we have quite a few patches to ensure different libraries compile well for Blender.

1. The OpenCollada team seems mostly unresponsive since a while. Therefore i think it makes about no sense to rely on getting the official library fixed soon. But well, sometimes magic happens, who knows.
2. Switching from OpenCollada to anything else surely takes a bit of time.
3. Removing Collada until a new Collada is available seem to me like a very very bad idea. I know that still many people rely on this import/export module.

Usually we dont track build issues here, but in this case I guess we should keep?

@Nathan Letwory (jesterking) I propose that we use a Collada fork for important fixes until we have migrated to another implementation for Collada or until collada has fixed their library them self. If blender won't host and maintain the fork, then i can offer to use my fork:

Oh I see that one " / " and " : " I did not know. Thank you for explain me.

Your images have following names (see UV Editor):

1. Open Small Stair.blend
2. File -> External Data -> Pacl all into .blend
3. Export Collada (,dae)

Finder preview there object is white no texture itself.

4. File -> Save

External Data. Really new word for me I never see that kind before. Thank you for explain me and I will try do that on "External Data"
Drag&Drop the .blend file this here report sure.
Take a moments processing until done to send for you later.

And again you throw tons of data into the report and let us figure out where to look at. And on top of this i can not even download your blendfile from dropbox, no idea why.

After trying to make sense of all of this i wonder:

@Mick Pearson (Mick-P) Would you mind to comment on the Issue that i set up in the openCollada project ? ( see https://github.com/KhronosGroup/OpenCOLLADA/issues/621 )

It is valid. xmlns is not an attribute. It just shows OpenCOLLADA is immature. Truth is, if xmlns is not implemented, then COLLADA is not really extensible, since it can't mix XML namespaces.

It turned out that fully supporting shininess in combination with BSDF Shaders is more complicated on the Importer side. Therefore i have removed import of shininess for Blender 2.80 and i will take care of this for Blender 2.81 the today's quickfix still needs approval though.

this are actually 2 bugs and one missing feature.

@Gaia Clary (gaiaclary) any more to do here?

For the record, if matrix and the others are present, then both should be applied by the COLLADA software. It's not a multi-representational option in other words. Second, regarding:

@Mike Lima (lunarbase) Hi, there. If you still are interested in this issue, could you please try with the next Blender 2.80 daily build (28-may-2019) if the issue is fixed? I am not entirely sure if the camera behaves as expected now. It is unclear to me what you mean by this:

@Daniel Balster (dbalster) The Blender 2.80 exporter now has 2 options for exporting transforms either as "Matrix" or as "Decomposed". The restrictions from older Blender releases no longer apply.

sorry. Easter holidays stepped in between :)

Ops... i completely forgot about this one :( I guess we can get this to work in 2.80 :)

@Gaia Clary (gaiaclary), seems this slipped through the cracks. Is it still relevant for the 2.80 with the new instancing based on collections?

already fixed properly by Brecht

Yes true no problem

I have talked with Kent online and he clarified that the issue has already been resolved. So i close this ticket now.

@Gaia Clary (gaiaclary) yes thanks.
@Philipp Oeser (lichtwerk) I did inspect deeply and they already fixed. Make sure daily build is today March 19, 2019 not use previous of January 2019 on old Blender 2.80 beta. Please make sure daily build is today (March 19, 2019) https://builder.blender.org/download/
For Macintosh Mojave MacOS 10.14.3
May I have your document .blend please also .dae too.
