I’m using Poser and the M4 textures work pretty well but the morphs need to be transferred—best way so I hear is with GenX but you have to buy that plugin and it’s not a Daz Original so a bit pricey at the moment; I’ve been hammering mine in the hard way with the tools in Studio, when they work well it’s pretty good but a long and tedious process that often needs adjustment afterwards to fix things up. Clothing is another matter, M4 outfits would need to be autofitted in Studio, then saved as a DUF and will work in Poser with a Poser Companion file. There ought to be a tutorial or two around here somewhere explaining that. Anyway, once you get that done it works pretty well except for certain boots and shoes that don’t convert well at all. I’ve found flat, thin-soled shoes work best with autofit, over-the-knee boots also provided they aren’t thick soled or have high heels, those always get distorted or hopelessly borked.
