  Yes I can check that if you like. Will post here what I find.

  Ok, RedDragoon provided me the script and I'll report my tests here. First one didn't go well, the script doesn't run. Is there any pre-requisite to run the script, or a specific installation procedure ?

  my steps:

  1. copy the glTF exporter in the script folder
  2. select G8F
  3. run the script
  4. I get an error that the script couldn't run

  [INFO] :: Failed to load script: C:/Users/Alessandro/Documents/DAZ 3D/Studio/My Library/Scripts/GLB Exporter 90.1/StudioBridge_GLB_Exporter_v90-Test_build_1.dse

  Thanks for the information are you still using DAZ Studio 4.23 by chance since I created it on a newer version I might need to install an older version of Dazsudio

  Yes I use 4.23 because 4.24 is not as stable, little rushed out. The SDK is the same though there's no reason why a script shouldn't work. My specs are always in the signature.

  update. Got the fixed version going to check.

  default G8F test

  Ok, here is my first test. I tried to import a default G8F in blender via the glTF importer. The result is less than I expected, that is, in my opinion the daz bridge is far better. However I'll be constructive and make suggestions, so perhaps you can improve the exporter. At this point it's not clear to me how much it's the exporter fault or the importer fault, as I never used glTF and the blender importer may very well have its own limitations. However, if this is intended to be used in blender, we have to deal with it.

  1. armature. The imported armature is unuseful for animation. The pivot points are all in global axes, so there's no way to rotate them along the local bone axis. I tried the various options in the blender importer but none of them worked fine. I suspect this is the same limitation of old fbx formats which only had pivots and not bones. Here a proper bone conversion is needed, if glTF doesn't support bones then it can't be used to export armatures.

  Also, a minor note is that the imported figure needs to be scaled down to 0.01 to fit the deafult blender unit that's 1 meter.

  2. materials. The material conversion is quite rude, it only exports the diffuse and specular textures, everything else is ignored. As for the specular factors, they seem off to me or I don't understand the setup. A proper conversion would be as follows, if we want to use the principled coat.

  • weight = glossy layered weight
  • roughness = glossy roughness
  • ior = 1 + glossy reflectivity

  p.s. Other than diffuse and specualr, you should at least also export the bump map, as it does a great difference.

  Let us know what you think.

  update. about glTF

  I never used glTF before so I expected too much. I did some research and I see it is a very limited format intended for realtime preview on web browsers. It is even more limited than fbx. In general I don't think this format is suitable to export daz models to blender, unless we want a very "shrinked" version fit to game engines and web browsers.

  For example glTF can't even handle quads or subdivision it's all tris, that's too bad for any decent conversion.

  I wanted this a year ago but now to be perfectly honest

  I cannot stand GLB

  and convert anything in that format to something else 

  cool you are doing this though and wish you success
