BackFace mesh work around, no work around?

ZBrush Usage Questions
#1

I recently imported a single surface into ZB, extracted a mesh from that with a certain thickness, used that new subtool to work from. I turned on polyframe and clicked autogroups to isolate the surface that I wanted to work from. Only one problem, it treated the whole thing as a single polysurface with no apparent color change for polygroups? I must be missing something here? I need to sculpt from one of the sides but because it is a thin part I can’t seperate a single polysurface through polygroups or use the backface command in ZB4? I have the trial version 3.0 where backface works but I cannot rely on that after the trial period for that expires or until they fix backface? Help!

I’m having a similar problem where nothing in the Auto Masking menu seems to work in ZB4. For a lot of my work, this problem is a HUGE game changer and something that I HOPE is fixed ASAP. If I’m just missing some new setting or something, it would sure be nice to find out.

I like your portfolio Sixus… Great talent bro. We need a moderator to respond to this thread??

Auto-masking is a known issue that the development team is investigating.

Regarding what happened with the polyframes for your model, a picture is worth a thousand words. It would really help to see what’s happening so that we can get a better idea of why.

PS: I moved this thread out of the tutorials forum because it’s not a tutorial.

IVe run into this anomoly with polygroups on a extrating a mesh and the object “appears” to be one group when in fact it isnt. Try this out for your selves and see if you can reproduce this I just did it and it works…

  1. Bring in or create a single sided mesh. Run extract with a positive or negative thickness.
  2. Using the ‘Control + Shift’ key selection tap on one side and you will see the other side turn off. ‘Control + Shift’ tap again and the sides reverses. The bug here is that the polygroups are not showing as different colors but they do exist.

Let me know if this address your issues… Thanks

Thanks NdeSomov, I’m aware of the ctrl/shift and it likes to make evrything dissappear with maybe a few scatterings left over, it should isolate only the surface that I want but it isn’t doing it, it’s acting up somehow. Maybe I can move it into 3.0 and try it out… Thanks for your reply…

I’ve included my file. Can’t isolate a single poysurface after clicking polygroups and placing everything into polyframe mode. I try ctrl/shift and it just cuts a hole through the surface and makes everything disappear… Tried it in trial 3.0 too and the same thing? Something is screwing up this command. My computer maybe? I don’t know…

Thanks dude. The guys here are actually really quick about responses and you can always bet that if it’s an issue in the program, odds are it will be fixed pretty soon.
