3D .OBJ import and lit manipulation in the free G’MIC, developing nicely and coming soon in version 3.1.3. And since G’MIC for Photoshop also works as a standard .8BF plugin in other graphics software, then they’ll also get the same 3D import capabilities.
Of course, older versions of Photoshop have 3D, but G’MIC will be able to provide simple 3D import for all current versions. From which, for some rather murky reasons, Adobe has ripped out all the 3D features.
Update: now released. Rather clunky at present, and .OBJ only (i.e. missing textures are likely). Experienced 3D users will be best to render in DAZ, Poser, KeyShot etc and export as a masked .PNG file.
