Hi,
I am trying to do some pattern on a column.Look at the attachment.
Thats the column,I am talking about.In the screenshot,you can also see the alpha that I want as pattern.Finally the pattern should stay on three red marked box.The problem with drag rectangle is,I can not position the stroke exactly horizontal or vertical.Is there a way to position stroke precisely(both angle and xy position-wise)?

Go into projection master,and if you want the pattern to be recessed in the column,first drag rectangle a square alpha on Zsub,then duplicate with Shift+Ctrl+s until you have a nice recess.after that you can drag rectangle your pattern and scale it in.
Hope it makes sense,i could whip up a screen/vid at lunchtime if its not clear
Draw stoke out then shift. To keep it in the marked areas, Mask them out then invert the mask.
But it would probably be easier just to use Projection Master or Zapplink.
You can see in the above picture that projection caused expansion at corner.It would be good to have a fade at corner.However, will this expansion cause problem in details extracting(normal mapping etc)?
Secondly,the whole column should be precisely perpendicular to horizontal line,if I snap with shift key.But it is not showing that behavior!!! What has gone wrong guys?
Now lets talk about second snapshot.
You can see that patterns are sharp and shine.And depth looks ok for me.But you will that.When I "pickup" on projection master,details will be lost.Patterns will no longer look so sharp.Rather,it will look like bloby.And after "pickup on projection master",you will have more depth than you expected.Is there a slider type thing that can control this behavior?
And you also see some noise in alpha.I did not paint it.How did they come in?
So after pickup,this is what I got.Below,
And finally,if I apply this projection master technique,this works for a plane,square type form.If I need to apply a pattern on cylindrical shape,it look terrible.Should I show you guys snapshot of it? Is there a way that I could displace my stroke,move it,even rotate my stroke at certain degree? That type of capability could really be handy on hard surface sculpting.
I tried several times with curve mode but it did not work for me.I hoped that I simply draw a curve,my stroke will be applied automatically on that line.But it is not working like that at all.First I drew a sample curve.Then my stroke did not apply.Rather,I had to move the points to reveal some weird position stroke.
The reason why the projection is blurry is probably because you have exported the model without equal quads.(in other words,create low poly model.
UVMap it,then duplicate it,and divide it in equal quads before export) the result on subdivision in ZB,you will keep equal quads,thus better distribution of details on your model.
However,do you know any technique of placing strokes more precisely?
I think I do not understand.After drawing,how do I shift position of stroke? I am curious if I can shift position of stroke.
But Bek, If I do that whole mesh move,rather the single stroke.
[EDIT:I got it.I have to apply Q-W in projection master.Only then I can move around strokes.]
I am checking zpplink.
wow,zapplink is great.Texturing is so easy with it.But how can zapplink do projection master's work, i do not understand.Zapplink is a texture painting tool where as projection master can deform geometry itself.
Is there a way of deforming mesh(rather than poly-painting) with zapplink?(like we do in projection master?)
Sure you can't get accurate enough with Projection Master?
I tried mask by intensity but it failed.When I press "mask by intensity" button under "masking",no mask applies.In photoshop I painted with pure black.
Here take a look
As for the intensity mask, be sure to turn off your texture once you have the mask created.
I do not know why but this happened.
This time mask by intensity worked with deformation palette settings.Problem lies within the picture that you will see.Here
See,it also deform other area that I do not want to be deformed.
