Answered: Warping pattern around complex object?

ZBrush Usage Questions
#1

Hi, I tried to warp an alpha around a complex object, I mean that it is not a simple cylinder, an alpha similar to the stitch brush.

I found some thread suggesting the warp mode of brushes, and using stencil.
I also tried the projection master method by using line but I have issues with these method, none of them work correctly, at least I can’t do it.

With the warpbrush mode the warping occur on all direction, is there a way to warp just around the horizontal line and not evenly in vertical and horizontal?

The Stencil method was suggested by aurick, it could do the trick, but you have to rotate around your object, it is not done in one shot, and btw how can you make your alpha tileable if you have to reajust your stencil everytime?
There is a way to stick your stencil on your object while rotation around it?
I tried to make the stencil and use fill color on it but it just ignore the stencil and fill all the object.
And like with brushes when using warp I haven’t find any way to just warp horizontally only.

And with the PM method, when you use normal and double sided the blending between the 2 sides destroy the alpha, it just strech it to reach the other side.

Thanks for the help.

The only other thing I can think of would be to temporarily assing UVTile mapping to your model. This fills every polygon with the entire map. You can then use that texture to derive a mask from it. If your model has uniform polygon distribution this will work well.

Thank you aurick, I forgot to add about the uv technique, that’s the only wich work, not the quickest.

I just wanted to know if I was doing anything wrong and if I missed anything, apparently I didn’t.

I hope it will be possible in a future version, and an other BIG wanted feature for these kind of work is to keep the size of the brush relative to the object.
Because when you are stamping or drawing pattern around an object if you zoom in or out while turning around, which is quite innevitable, the size of your pattern change because the size of your brush is absolute (or relative to the screen) and then if you zoomed in you will have a smaller pattern, if you zoomed out you will have a bigger pattern.

I am always trying to guess the size to get it uniform and that can be time consuming.

Maybe I missed something.
