Load Material: Multiple products and "Use new material" option creates one per product

[BigRoy]

Issue

I tested it in Blender 4.0.2, and selected multiple images at once before using right-mouse-button.

If the object does not already have a material, or if you select New Material in the option popup, it creates several slots/materials (one for each image that is loaded), which is disturbing.
In the case of a new material, I think it would be better to load all selected images into a single material.
Because when you load several images, it's usually normal, baseColor, Roughness, etc... which are all intended to connect to the same material and slot.

Expected Behavior

It should create one new material in which it loads all the loaded textures instead.

Workaround

For now the workaround is to first create a material manually if none exists - and select that. Then all will be added to the one material as intended.

I have tested in the latest ayon-blender 1.0.3 and it is still issue....

Also worth noting that not only unneccessary materials been created but also the fact that the default material slot remains empty but new mats been appended next to it so the shader editor been still empty without any visible nodes loaded...

@moonyuet @BigRoy any chance to be resolved soon?

Likely not unless prioritized by client. It may require some changes on how loading works in general, and hence may even become easier once Load API has been redesigned.

I did make something similar few years ago (Personal use only, so not a clean code though) in blender which connects to all texture in a new material but not sure if it helps now due to the changes on the API.

Just few more notes (as I have tested it again in the latest ayon-blender addon 1.0.16

Apart from creation of unneccessary materials (for each image which been loaded in bulk) it has also issues with disabled Use Nodes option as there is no existing material node tree then for each newly created material.

and giving this error msg:

Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'nodes'

Ideally, the solution should be to give just single material if new material option been used and with enabled Use Nodes option too...

Thanks @LiborBatek for documenting. Just wanted to mention this is very low priority currently.

yeah it was more about inspecting whether still an issue or not and if it should be closed or not, found those during that occasion so put it here...

but I got it, thx anyway!
