Morph Scaling Issue

edited December 16 in Technical Help (nuts n bolts)

I'm having a morph scaling issue where my pipeline is as follows:

  • Export G9 from DS 4.24.0.3 at base resolution using the latest Daz To Blender bridge available in the DIM
  • Import G9 to Blender 4.3.2 using Daz To Blender bridge
  • Sculpt G9
  • Export G9 from Blender using the .obj exporter
  • Import G9 to DS using Morph Loader Pro

No matter what I do, the scale is off when imported back into DS.  I'm having to use a scale of 0.410 when exporting from Blender in order to get it to work.  There's still a very slight change in scale even at that setting, but there should be no change at all, and it's obvious that having to use a scale like that means that something is not right somewhere in the pipeline.

Since I have no idea what scale is used by Daz To Blender when exporting from DS or importing to Blender, I'm finding it impossible to locate the problem.  YouTube videos and forum searches haven't helped since I'm using Daz To Blender to export and Morph Loader Pro to import.

If there's anyone using the same pipeline, it would be appreciated if I could have the following information:

  • Scale used by Daz To Blender when exporting from DS
  • Scale used by Daz To Blender when importing to Blender
  • Scale to use when exporting via .obj from Blender
  • Scale to use when importing via Morph Loader Pro to DS

    That sounds as if you are using the Poser preset in Morph Loader. OBJ has no inherent scale, so import and export make assumptions - use the same preset for export and import in DS, and 100% in Blender, and all should match up.

    I did try the Poser preset at one point, but only because what should have worked, for some reason wasn't working.  I must have been careless with my settings somewhere along the line.  I wasn't aware the .obj format had no inherent scale, so the Daz To Blender bridge not offering a Scale setting for export makes way more sense now!

    Thanks, and much appreciated.

    The Poser preset is probably the problem, I would sugest using Modo or one of the other 1 unit = 1 m presets on import. But the point is to match the import and export presets (which will cancel their chnages out) while leaving the import into/export from Blender unchanged.

    DTB doesn't use OBJ format but FBX which has no scale options for both export / import in DS / Blender. So DTB always exports as 100% in DS, imports as 1 in Blender (by using FBX importer).

    So, if you use DTB for the sculpting workflow, you just need to export to OBJ in Blender with Scale 100.  Screen shot 1 is for export OBJ in Blender. Screen shot 2 is for import with MLP as default.

    Don't use Blender or whatever other Preset in MLP, just use Default.

    Sorry, Richard.  To be clear, I followed your suggestion and it works fine now.
    Thanks and much appreciated.

    Crosswind, all working now.  Pretty sure I used Default the first the around, but somehow managed to mess-up a setting without realising it.
    Thanks and much appreciated.
