    Default Pixologic Release: SmoothGroup Import (PC & Mac) UPDATED for V3.5R3 Win

    SmoothGrp.jpg

    This plugin is designed by marcus_civis for those who like to work with smoothing groups in Max or an app that supports them. It will import an OBJ into ZBrush and automatically crease the borders of any smoothing groups. If there are regular groups these are unaffected.

    This plugin is now available for ZBrush 3.5R3 PC and ZBrush 3.2 Mac.
    You can get it from the Download Center.




    INSTRUCTIONS


    Press the button and select an OBJ file from disk. You will have the option of importing into a mesh in Edit mode if you wish. The file will be imported and if there are smoothing groups defined the borders of each group will be creased.

    To uncrease the smoothing groups after subdividing to the required level, SHIFT+click the Tool:Geometry:UnCrease button.



    INSTALLATION

    The zip contains:

    SmoothGroupImport.zsc - the plugin file
    SmoothGroupImportData - a folder which contains:
    ZFileUtils.dll - the dll file

    SmoothGroupImport_readme.txt - the readme file


    Unzip the zip file to your ZBrush3\ZStartup\ZPlugs folder so that the structure is like this:

    ZBrush3
    |--ZStartup
    |--ZPlugs
    ... SmoothGroupImport.zsc
    |--SmoothGroupImportData
    ... ZFileUtils.dll
    Restart ZBrush. You should now have an Import & Crease button in the Tool palette (below the Import button).

    A sample file of the belt buckle shown above may be download here.


    We hope you find the plugin useful.

    I can't download the plugin due to this error message:

    This server can only be accessed by the proper referring server.

    What does that mean?

    By the way, it would be nice to have a crease all groups script. For us, who are not working with max

    Marcus, is there any plan to extend the plugin with importing creased edges from Softimage, etc.?

    Does Softimage export creased edges in an OBJ? If there is relevant data in the OBJ then it should be possible. If you can try a simple cube and send it to me, I'll take a look.

    Looking at the generated OBJ file, it doesn't, but it export vertex normals. It looks like that if vertex is hard (not smoothed) it's normal points to 0,0,1 direction. Otherwise the vertex normal shows fraction numbers.

    The cube.OBJ is attached.

    Thanks!

    Thanks. I think it may be more complicated than you suggest, after all this is only a cube and what goes for this may not necessarily go for more complex shapes. I presume the normals have been adjusted so that some faces appear smoothed but I'd need to understand more about how the normals are calculated to be sure and to make use of it. I'll look into it as it interests me but I can't promise a speedy result. (I've a lot on at the moment.)

    How do you define a smoothed area in XSI? Could you define the area as a polygroup instead? This is essentially what is happening with the Max 'smooth group'. The only difference with ordinary polygroups is that the faces in the OBJ are grouped under an 's' tag rather than 'g'.

    Hey Marcus, nice idea.

    In XSI there are hard edges, and smoothing performed over these edges. IMO that's far simpler to work with (on the artist side). There are also Clusters (sub-element groups). Alas XSI doesn't export clusters in OBJ, unless it has different material assigned. I may create a script to XSI that makes the Smoothing group cluster with SM prefix in the name, assign the same name as the cluster. Small preparation on XSI side, but it worth it.

    Here is a cube exported as I mentioned

    The download page says the 3.5 version is coming soon. There is no 3.1 link. Where can I find this?

    Is there an ETA on when this is going to be available for zbrush 3.5? This plugin is integral to my workflow.

    I've been running 3.1 alongside 3.5 R3 just so I can use this plugin, as it's integral to my workflow as well.

    Every time I piss and moan about Pixologic being slow updating their plugins they surprise me by doing an update a few days later. Hopefully this will be the case, but I have a sneaking suspicion they won't bother and just make it part of r4 or v4, whichever comes first.

    It still annoys the crap out of me how they lure us in with these awesome plugins, make them part of the reason to buy ZBrush, let us develop a great workflow with them, and then don't update them along with the rest of the program thus breaking our workflow; having us choose between updating to the latest version with new amazing features, or stay with the older version for a few more months just because the way we work depends on it.

    There, done complaining. Just please get your s**t together, Pixologic. You make the best 3D sculpting software out there, and I love you to bits and pieces but I feel like I'm in an abusive relationship here where you take me for granted :P
