Hello, dear Sasha developer, I am a beginner. 1. I need to increase the number of polygons on the V4 model, for example in Zbrush and return it to Poser pro. How to do it right?
2. Could you show by way of example how you put "karine" in Zbrush. Thank you

Hi there. First off, what verison of Poser are you using? The most recent verisons (10, PP2014, 11, and PP11) all have built in Pixar Subdivision tech. You just have to change the skinning method in the figure drop down menu. As far as I know, there is no way to subdivide the figure in Zbrush, reimport it and keep the fuctionality of the figure with out re rigging it. The morphs will not work either. Poser native subdivision, if you have a newer release of the software, is basically your go to.

Could you show by way of example how you put "karine" in Zbrush.

Im not sure what you are asking. What is 'karine'? And, sorry if you mistook me for Karina, I'm just a user of Sasha, I did not create her.

Kolo, I don't have Zbrush (yet, anyway) but here's an idea. Do you know Blender? It's free shareware. One simple thing you can do with it is import objects and, in edit mode, subdivide selected polygons. This makes that whole or part of the object more flexible for morphing, which I suppose is what you are after.
But note I speak of objects. If your object is a body part-part of a character-I do not have experience getting the new object back into the character. Poser's Set-up room and/or Zbrush can presumably do that, but again I don't know how.

I'm pretty sure Karina did most, if not all, of the new custom morphs for S-16 using Poser's Morph Brush tool. You can increase the subdivision level on a figure in order to have more detail to work with, and set the Morph Brush to "bake down for subdivision," so that your changes still work when SubD is set to 0 (though with less detail, of course). That is by far the easiest way to morph a Poser figure b/c you don't have to worry about all the problems that get introduced with exporting and importing OBJs. No ZBrush needed!

To increase the subdivision level on S-16 (or any figure), first go to the Figure menu, select Skinning Method, and select Poser Unimesh. Now when you go the figure's properties panel, you'll see that the Subdivision Levels section is now functional, so you can use the sliders to set the level.

If you really want to make morphs in ZBrush, you'd do that for the S-16 version of V4 the same way you would on any other version of V4. So you can use Google to find tutorials on that process, since it's not specific to the S-16 version of V4 that Karina created.

Hope that helps!
