System Information
Windows10, Linux Mint 19

Blender Version
Broken: 2.76, 2.78, 2.79 (first report)
Broken: 2.82 (updated report)

Short description of error
Can't embed texture maps in collada file except diffuse.

Exact steps for others to reproduce the error

Open the test.blend file, the material uses a basic node setting (texture ccordinate>mapping>image texture and a 'normal map' node for the normal texture), with textures assigned to diffuse, specular and normal
open the export to collada window,
make sure "copy" is checked in the textures options,
export the file
import the collada,
the model has only the diffuse texture map.

Tried exporting to fbx I was able to embed textures for diffuse, roughness, specular and normal.

@AbdouCher Please check this with the latest Blender build from https://builder.blender.org/ to see if you can still reproduce it. If you can, please attach a blend file with the relevant images packed in there, so that developers can easily reproduce the issue as well.

Will close this for now. @AbdouCher, if you are still able to reproduce the issue in the latest build, you can reopen this report. Make sure to provide the additional information @dr.sybren asked for in the task description. Thanks.

Hi,
Sorry for answering thia late.
First of all, since blender internal is no longer available in newer versions of blender I'll be using cycles as now it supports texture embedding when exporting.

Abdou,

I am experiencing the same problem. I will need to switch to Maya unless I can find a workaround.

can you explain what you mean by this:

" I'll be using cycles as now it supports texture embedding when exporting."

how are you using cycles to export collada files with normal or specular maps?

thanks

Tim,

The problem was originally reported in blender 2.79 and earlier using blender internal renderer because back then cycles didn't support embedding textures at all, what I meant is, since BI in so longer resent in version 2.8 I am using cycles as now, in theory, it supports embedding textures.

Sorry for the misunderstanding.

Abdou,

thanks for the update. do let me know if you find any way to support exporting specular and normal textures to collada.

I am not sure how we could get the data out of the node system in a general way. I mean those textures and maps can be located anywhere in the node tree... And as far as i understand we have no way to extract this data from an arbitrary node tree, unless we make assumptions... And that won't work nicely.

So the only way to go would probably be to bake the material (if that is the correct term in this case) and then extract the data from the baked material. However i am not sure if we can do this programmatically in a convenient way.

Maybe we need a function "get rendered data for export" which could allow to get ready made textures and maps ?
