Incorrect Texture Mapping

[apptaro]

Some of converted GLTF files have incorrect texture mappings:

[apptaro]

Version: COLLADA2GLTF-v2.1.2-windows-Release-x64

DAE and GLTF data attached:
data-uv.zip

Possibly related issue: #174, #175, #116

[apptaro]

All DAE files are exported from 3ds Max.
BabylonJS, Three.js and Cesium all render in the same way.

This should be mostly fixed in the latest version of #180 that allows for multiple texture maps.

There's a little bit of weirdness on one of the bulbs in the lamp model still, and I'm not sure what the cause is yet.

[apptaro]

@lasalvavida wow, very nice, I'm looking forward to the next release. I have many other cases with this issue, so once the fix is released, I will try them all.

[apptaro]

any plan to release the fix?

[lasalvavida]

Hey @apptaro. It will be released once I have tested it more thoroughly.

If you want to use it/help test it in the meantime, you can grab pre-built artifacts for windows off of the appveyor job for the pull request like this one: Windows x64 Release multiple-maps

[apptaro]

@lasalvavida Yes, I would like to use and test it. I downloaded the one above, but it has the issue #200 and was not usable.

[lasalvavida]

Sounds good, #200 is next on my list.

[apptaro]

@lasalvavida Let me know when I can test it out.

[apptaro]

@lasalvavida Now I have figured out how to get the latest build from appveyor job, and tested it out. About 50 models are fixed. I have some models that still have the same issue, and some different issues. I will let you know when I am done testing.

[lasalvavida]

Thanks @apptaro - the testing is very much appreciated!

[Ld-LaoWu]

I'm very looking forward that,but this is my stuff for multiple-maps and let that support THREE.js

[apptaro]

@lasalvavida After testing all my models, only cases with this issue are dress-pendant-light-l-black.dae (above) and dress-pendant-light-l-white.dae (attached here data2.zip)

Tested with Build 2.0.314, COLLADA2GLTF-master-windows-Release-x64.zip

@lasalvavida it'my model .lightmap and diffusemap ,SO I have two layers of texture uvs for that and i I have modifieded the struct of outgltf and made it satisfied with it. and I want to compile your program so that i can control what i can output.can you give me a corrent program on windows? Waiting online,（i can not solve the erro about camke's Compiling）

[lasalvavida]

@mycleaerlife, you can download Windows builds for any commit from the corresponding AppVeyor job artifacts tab like this one.
