Hi Community,
Run into a little problem with Zbrush 4R7 P3. I have been trying to create a low poly hair (curve) brush but am not having much success with the welding of the curve? Created the Tri part brush with gaps and no gaps (quickly checked Zclassroom) created the Insert mesh>Activated Curve mode. Under Brush modifiers, set weld points on and stretching but when activating Dynamic Subdivision the points weld and don’t weld!
Any help will be greatly appreciate, Thanks
Are you familiar with Fibermesh? You can reduce the profile so it’s only creating 2d strips.
Also, the Curve Strap brush, with the brush modifier set to zero in the picker menu that comes up when you click on the brush icon, will draw out a 2d strip of polys along a curve. Control the width with the brush size, and control the number of segments with the CurveStep setting in Stroke> Curve menu.
Thanks Spyndel,
Fibermesh, is a great feature. Made a Bumble bee earlier this year using it but it’s not quite what I’m looking for.
I tried the CurveStrap Brush with the settings you gave me (learn’t something new today). At setting 5 on the Brush Modifier it gives me a seam down the middle and with Strength Multiplier to 1, I get a bit of volume.
I will just have to Polygroup front and delete the back faces.
Thanks again

This is what I get with the Curve Strap snap brush with a Brush Mod of zero, and a curve step of about 5 or so. The line you’re seeing down the center is probably just the curve itself which will be there until you confirm the stroke:
Unfortunately, I was mistaken about the nature of the result. It actually creates two strips of overlapping 2d polys, not a single one. This is likely to be problematic for your purposes. Curve tube also produces these results with similar settings.
Im afraid I can’t help you further. My instinct is that what you want to do should be possible with an insert mesh brush and a curve stroke, but Ive never tried to do it, and cant advise you on the settings.
Sorry.
Thanks Again, yeah I tried the Curve Strap Brush again and when it comes to Polygroup from front it misses aroung the bottom edge. Tried diffrent angles but not working out!
Will carry on with the brush I made and then weld points under Modify Topology for now.
Cheers

Use “Groups by normal” with the default angle.
Then you can easily select the wanted groups and delete the rest.
Hi Thor,
Tried your method with the Group By Normals it works but I would have to select each individual hair as I go round.
I just might be missing out a setting or ZBrush is unable to weld all the points on a 2D strip, as in first images in welds and then doesn’t weld?
Thanks

You’d have to weld the points manually with geometry>modify topology> weld points, and jack the distance slider way up to make it more aggressive. The weld option in the brush menu doesn’t seem to do the trick. Even then, you would want to first split all the strips into their own subtool to keep them from welding to the original target object, and depending on how curved the strips are, some points just will not line up close enough for welding. Nothing I did was able to get the two overlapping poly strips to weld together. But I did create a custom single plane poly strip brush were the points welded successfully about 95% of the time.
Hi Spyndel,
Yeah, I think thats the only way to go at present! The weld in the brush modifier definitely not doing what it should (32Bit & 64Bit).
Thanks for taking a look and appreciate the help!
