Zbrush 5r6
First if sorry for my silly question, I’m a beginner.
I follow the tutorial about zipper brush, How to use them, basically by IMM Curve brush I draw the zipper tape, then with one of the zipper brushes I add the zipper. While drawing with the IMM curve brush how can I drow a straight line? Which key of my keyboard I must push to draw straight lines?
I try the usually shift, etc, they dont work.
Sorry again for my silly question and thanks for your help.
Thanks a lot Doug Jones for your help!
Lazy mouse is one of the first command that I try with, so no keyboard key to draw an IMM Brush straight line?
In the zipper tutorialon youtube lines, IMM curves are drawn perfectly straight, at list it looks like, as some key is pressed constraining the brush stroke to a streight segment,
Thanks for your help
Look in the stroke palette, there’s a button for that 
AsLine.
Thanks a lot Doug,
that is the command that I was looking for, really apreciated!
Thanks for your help, really apreciated!
Two more beginner questions:
as exp my tool is Victoria 4, I extract a mesh from her body, a simple clothes.
I would like to give to my clothes a texture, I polypaint it. I want export my clothes with texture to another application for final rendering, the final output will be done in Poser.
Before export my clothes and its texture to Poser do I need to generate uv coordinates for my short?
How can I generate them? Can I do it in Zbrush or I must import my clothes from Zbrush to a modeller, as exp 3ds Max, generate the uv coordinates then move to Poser?
I would like to add to my clothes a simple zip, I do that trough IMM Zipper brush. I split the generate zip as subtool of my clothes. The zip has already uv coordinates or I must generate them as asked in my first question? Generally mesh generated by those IMM Brushes have already uv coordinates on them or not?
Thanks a lot for your help!
