I port clad-figures and props to Poser from a range of different formats found on DS, DA, BowlRoll etc etc.

There's an excellent thread on Rendo' forums for getting DS 'Gen' figures into Poser. Inspired by that, I've ported a then-free, sassy 'Gen_7' character who may have escaped from a 'StarWars' prequel...

Some DS props, 'under the lid', are legacy Poser format, others may be exported from DS as OBJ+MTL.

Similarly, 'MikoMikoDance' (MMD) X and PMX props and scenes may be exported from DA's free PMX_Editor as OBJ+MTL.
Several 'gotchas': MMD coordinate system is reversed wrt OBJ, so mesh exports are 'mirrored'. Though PMX_Editor has a 'mirror' tool, matching up mapped textures can be 'interesting'. These textures and their calls may be 'many', and in Asian glyphs. Unpack such using eg free Bandizip lest you get 'Dipthong Soup'. Google Translate is handy...

Rigged MMD figures other than TDA-type ('No Port' T&C) may be ported to Poser-compatible rigged FBX using TrueBones' $$ utility: As yet, seems unable to convert texture calls, which must be hand-applied. Not a problem, unless 'many'...

XPS props and scenes may be directly exported from free XNA/Lara Editor as OBJ+MTL. Scaling varies widely, finding model is often 'interesting'...
Rigged XPS figures may be exported from XNA/Lara Editor in rigged .MESH.ASCII format, which free Noesis can convert to rigged FBX. If you get many sub-rigs, parent second and subsequent to first ASAP, warily place and pose using first. Again, Scaling varies widely...

As XPS figures often have multiple clothing / accessory options, some sub-rigs may be safely deleted, reducing Poser scene complexity, increasing stability...

Note XPS 'Mods' are like 'Morphs', which cannot be ported unless base mesh is included...

SFM meshes and textures per 'MLP' and 'Garry's Mod' may be extracted by free Noesis, exported to OBJ+MTL or FBX. As textures are extracted separately to meshes, you must hand-apply them. IMHO, 'MLP' eye-mapping is often 'weird': Due Care, Please ??
