Convert OBJ to DSF

A DAZ Studio content library needs an OBJ model packaged as a native support asset when you want to reuse it as a DAZ prop. DAZ Studio can import the mesh and save its geometry as DSF; renaming the file does not convert it.

What the OBJ format is

OBJ is a widely supported 3D mesh format used to exchange static models between applications such as Blender, Maya, and 3ds Max. It can store vertex positions, polygon faces, normals, and UV coordinates. Material assignments are commonly referenced in a companion MTL file, while texture images remain separate.

What the DSF format is

DSF is a DAZ Studio support-asset format based on DSON, DAZ’s JSON-based scene and asset representation. A DSF asset stores DAZ-specific data such as mesh geometry and is intended for use in DAZ Studio’s content system, not as a general-purpose mesh exchange file. User-facing DAZ scenes and presets are commonly saved as DUF files.

How to convert OBJ to DSF

1. In DAZ Studio, choose File → Import and select the OBJ. Set the import scale and axis orientation to match the source application. Preserve groups, surfaces, and UVs if the model needs them.
2. Check the imported prop’s size, orientation, and appearance. Assign or repair surfaces and texture paths if the MTL data or image references were not imported correctly.
3. Select the prop in the Scene pane and choose File → Save As → Support Asset → Figure/Prop Assets. Enter the vendor, product, and item names, choose the content library location, and save. DAZ Studio writes the support asset, including its DSF geometry, into the library’s data structure.
4. To make the prop easy to load from a content library, save a user-facing preset or scene subset as a DUF file in an appropriate library folder. The DSF support asset and its referenced textures must remain in the expected library paths.

There is no dependable general-purpose online mesh converter that creates DAZ-compatible support assets and the required library structure; use DAZ Studio for this conversion.

Compatibility and limitations

OBJ does not carry a DAZ rig, animation, or DAZ-specific morph controls, so those are not created by importing it. OBJ material and texture references may require manual correction. A DSF asset is intended for DAZ Studio; use OBJ or another interchange format when the destination is a different 3D application.
