Question about Sub-D

Is Sub-D a DAZ Studio only trick, or can it be used in other 3D rendering programs like Poser?

    I do not use Poser, so I cant say anything about it. But SubD, better said "mesh smoothing by subdivision" is absolutely no DAZ Studio trick. This is a well known and used method that most 3D software applications can do. The names may differ, but the method is always the same.

    Poser 10 and Poser Pro 2014 now use Pixar Subdivision Surfaces.

    If you google it, you will find loads of links. Hexagon also has smoothing, and it is done by sub-dividing each polygon into four polygons. It can do wonders for rendering and the smoothness of a model, but there is a cost, four times the poly count, and an increase in render times.

    There is usually nothing for nothing in CG graphics :)

    Did you perhaps mean "will the subD effect generated in DAZ Studio be applied to the model when the model is then transferred to another program"? I just tried subdividing a cube in DAZ Studio and sending it to Bryce, but the subdivision effect does not appear in Bryce; it seems it must remain in DAZ Studio. I haven't tried the same test with other applications though, so I don't know for certain if that will always hold true.

    I ask because It seems almost all items sold are made using Base Resolution without a second selection for High Resolution. If I want to add Sub-D I must do it myself as it's not native.

    I am curious to know if there is a reason for this.

    Does giving an item a Sub-D High Resolution Geometry, natively, restrict compatibility with other programs?

    NO it doesn't restrict the use of objects in other programs. I have exported Sub-D objects in the past.

    Yes there is a reason and that is down to a number of things. First one is computer memory. Though Sub-Ded objects are only subdivided at render time it is still a memory hog. Some objects are that well made they don't need it. Some products are made in such a way that they cannot be SUB-D due to the mesh distorting due to how the base mesh was made. Plus if one wants to use it, it is only a couple of clicks away. Genesis and Genesis 2 use Sub-D as default as that is how they were designed. Great for reducing memory when working on a scene, with memory usage only increasing at render.

    Most figures I load, load at high resolution. Many props load at base. If I'm going to do morphs for a figure, I will export at base resolution and up it one level in my 3D application. For HD morphs, you can go to level 3 for export. Depends on what you're trying to do with the exported objects/figures.
