Cannot "Draw" in edit mode

ZBrush Usage Questions
#1

I looked on the boards for this answer with no luck.

I am doing the Head Sculpting and Texturing tutorial from Gnomon and am on the section where you edge loop the eyes to create more geometry for more detail. So I’ve done that successfully and have hidden the head to work on the eye details now. In the DVD Alex shows you how to add dimension w/ the “draw” tool, but when I try to there is no change on the model. I can however affect the geometry with the “move” tool, I just can’t draw.

I have followed Alex’s directions to the tee and I’ve even matched all of his settings and resolutions etc. to be sure I wouldn’t run into any problems…Please help.

I have included a screen shot to observe my setup. Picture 1.jpg

If your draw size is small, then the Draw tool won’t have much of an effect. It really needs to have several points within its area of influence in order for much to happen, and according to your illustration you’re only going to get one point at a time for most of your model. Also, your Z Intensity is set to only 6. That is a VERY small amount of depth adjustment. Combined with the draw size, it’s unlikely that you would see any effect at all.

#3

Thanks Aurick, I’m glad to see I’m getting the hang of some of the Zrules, because I felt that may have been my problem as well, however when I up the intensity and the draw size, I am still unsuccessful.

Oh something I forgot to mention, my model starts to rotate when I try to draw too at any intensity or draw size.

#4

Any ideas how to solve this problem?

How else would I get fine details other than the current method I am using?

#5

Just a friendly bump…

#6

In order for an editing stroke to be seen as intended for editing, it must start on a point. Otherwise, it’s interpreted as intended to rotate the model. When working with you mouse over a part of the model, ZBrush starts looking for the point closest to center of the cursor. If the model has a lot of points, it finds something and locks on really quickly. If the model has few points, it takes a little while to spread that search out until it finds one to grab onto.

When working with a low poly model, watch the red dot. When you see it lock onto a point, that means that ZBrush is ready to begin an edit. Click too soon, and ZBrush will think you want to rotate the model.

#7

Thanks again Aurick, I hope to get the hang of this soon.

What does it mean if I divide the polys and still have the same problem even with a bigger draw size and intensity?

#8

Cannot be possible :slight_smile: Simple

#9

Unfortuately it’s happening to me. I’ve divided 3 or 4 times only to have the same problem. I thought maybe I did something wrong, but I am following the tutorial exactly.

A few things to check … your brush is blue which, on a PC, means you have your Shift key held down. Don’t know if it’s the same for a Mac. Have you got Caps Lock on? Generally Shift forces your brush into ‘smooth’ mode and you won’t see much effect.

Something else to check is what brush you’ve got selected in the Transform palette. Maybe it isn’t Standard or Inflate selected, but something with a fairly ‘quiet’ effect.

The other thing that comes immediately to mind is the ‘graph’ shape of the brush. If you’ve been playing with that and created a flat brush with a low profile shape, you could brush on a model all day and not see any change.

#11

I think I see in the image that a mask is also on, true??? :wink:

#12

Hi Moochie—The brush looks blue because I took a screen shot which involves using the shift key…Yes Mac is the same as PC in that respect. push shift to smooth and the brush turns blue…Caps Lock is off…Also, I am using the standard brush during my draw sessions…I don’t know what you mean by ‘graph’ shape of the brush, but I have not (intentially) changed it. How would I check that out?

Hi Jason—No there isn’t a mask on it. Actually I was thinking the same thing but double-checked it to be sure. Thanks for the input.

I can create a sphere tool in the same document and draw on it dimensionally with no problems at all. I’m confused. Does anyone think I have a corrupted tool? I could email it to someone who was willing to try it out if interested. Maybe it’s not my fault afterall (doubt it though).

Thanks for caring about my troubles, hope to hear back from you…

HYDE:

It really sounds like you have some mask turned on. It is possible to have the mask on and still not see that it’s there. Remember, you gotta click the Tool>Masking>Clear button to get rid of invisible masks.

What happens if you clone the tool, then try modifying the clone?

One other thing to check which is rather obscure and unlikely, but might somehow be unset: Look in the Transform palette, under the Modifiers subgroup. There you’ll find four buttons, xyz, x, y and z. If ALL of these buttons are off, you won’t be able to deform the tool… but you wouldn’t be able to pull points either.

If you can, post a link to a zipfile of your model and someone might be able to look at it and solve your problem.

Thanks Sven. I cleared the mask as you suggested but still no change.

#15

BTW Sven, I also checked the xyz settings and all are A-OK.

I forgot to mention that I’ve included my ztl.zip in my previous reply if anyone wants to play with it. If you find the problem please lemme know. Thanks and Good Luck

#16

Hell never saw something like this in my life…

but found a solution…

Just press clone in the tool pallete…select the new cloned model and it will work :slight_smile:

phew went crazy for sometime… :rolleyes:

why it happened I still dont know :o

#17

Hyde,

I downloaded your model. As you indicated, I can’t modify it in draw mode either and I can’t figure out why.

However, I cloned the model and loaded the clone. I was then able to modify the clone in draw mode as normally expected. Agqain, I haven’t figure out why.

If you give that a try, you should be out of the woods.

I’m going back for another look at the original model to see if I can isolate the problem there…

Ya Sven

Even I need to find out … why … :frowning:

#19

Ok Sven I got it

Thanks to a recent question on this very forum…

The object has become transparent for some reason …

Aurick showed this technique …

http://zbrushcentral.com/zbc/showthread.php?t=36183

draw it on canvas…
do not enter edit mode…

take rgb intensity and z intesity to maximum,

enter again in edit mode…

Bingo here you go…

i noticed when I am trying to move the points say of eyes, its moving of the shoulders, then I realized its transparent… :slight_smile:

Sunny,

Yes, you’ve solved it. That’s a new one on me.

edit: After further tests, I’m totally amazed at this oddity… Try loading a model, but before drawing it to edit, set the Z Intensity to something like 95. Draw the model, go into edit mode, and try the standard modification of the surface using Zadd. For me, it draws THROUGH the model and begins to modify the rear surface! Weird! I can’t believe I haven’t happened on this before with all the damned models I’ve built.
