 Does anyone know the settings for exporting morphs back to Daz from Blender 4 obj export (not lagacy obj export)? I finally upgraded to Blender 4.0.2 and it doesnt have the lagacy obj exporter that I've been using. Now I keep getting geometry doesn't match in Daz Morph Loader Pro, even if I dont touch the mesh at all. I've tried tons of different settings in Blender export, no luck. This pic shows nothing selected in Blender export because I even tried that.

    If geometry didn't match, is usually caused by exporting in High Res, or if it is a character, to forget to remove eye lashes etc.

    No, it's a simple shirt at base res. I've done it tons of time with the legacy obj, but they got rid of it and the settings or different in 4.0. I'm just going to stay with 3.6 until I figure it out.

    The prime difference to legacy, is they have removed 'keep vertex order' as a check box as it is default.

    If it is a shirt, have you then removed e.g. buttons attached with rigid foloower nodes?

    why is shirt.obj 17mb but shirt1.obj only 6mb? maybe you forgot to select all...

    I tried to make a simple morph for the basic tank top in the G8 package, and it works fine here. For a morph you only need to export faces, the other data is not necessary and may be what it is giving troubles. I'm attaching the daz and blender options I used.

    In some rare cases the daz geometry is not good for blender and it needs to be validated, this means blender may change the vertex order on import to fit the internal data structures. This may depend on the application the PA uses to model the asset.

    I would suggest the safest settings for exporting / importing OBJ as below. (Geometry Only) Then save it as a Daz Operator Preset.

    Make sure the figure / prop in DS has no fitted geo-graft on it otherwise the geometry won't match...

    Why do you export UV and normals to create a morph?

    Because 1st, that's default options which has no impact to creating morph. 2nd, sometimes I do need them for other tasks, so I saved them as my Daz Preset. Then I don't have to check / uncheck them from time to time.

    If one doesn't need them, just uncheck them from the preset.
