Gaia Clary (gaiaclary) closed T66899: Exporting to Collada sets material roughness to 0 as Resolved by committing rBdd3e3474abcb: fix T66899: Collada: Shininess/Reflectivity not handled correct.

Gaia Clary (gaiaclary) added a comment to T66899: Exporting to Collada sets material roughness to 0.

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.

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:

Gaia Clary (gaiaclary) closed T34062: Collada: fix broken export of transforms (and adds new bake transforms option) as Resolved.

@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.

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

@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.

Gaia Clary (gaiaclary) abandoned D4476: Collada Exporter: Specular value was exported as greenish color.

This patch now has been replaced with a more complete fix for blender 2.80.
Thanks again for reporting this issue! This was truly a good find!

Gaia Clary (gaiaclary) commandeered D4476: Collada Exporter: Specular value was exported as greenish color.

thanks for the patch. I took a look at this and i found that actually the shader value is not a color but a factor, so the function returns completely wrong data. So actually Collada should not export a specular color but a specular factor. I will add a fix for this.

This issue has already been fixed in the master branch (for Blender 2.80). I also believe that this particular issue has been there since ever. Maybe back porting the fix to 2.79 might not be too important?

William Reynish (billreynish) added a comment to T60697: Collada: multiple Materials problem.

@Kent Davis (mac4kent): Blender uses the same codebase on the Mac as other platforms. There may be sligt differences caused by differences in GPU's and other things, but Blender is basically the same on Mac, Windows and Linux. For this reason, the platform (Mac) is very unlikely to be the cause of most bugs.

@Gaia Clary (gaiaclary) Sure, but the thrust of this (COLLADA) ticket IS losing primitives. The materials are lost because the primitives are discarded @Trevor Glauz (TSGlauz) says this defect is something core to Blender.

Blender should not loose vertices, edges or faces on import, at least not with Collada.

Mick Pearson (Mick-P) added a comment to D4187: Collada Importer Material Assignment Fix.

Removing duplicate edges/faces is just how blender works since it is considered invalid data. You can have duplicate vertices, though. And with duplicate vertices, you can overlap faces that use entirely different vertices that sit in the exact same positions. You can also duplicate triangles into separate meshes and overlap them that way.
