Geometry and Quality Problems

[system]

Hi ppl im new as you can see, but i will go straight to the point:

(Please scuse me of my gramatic and syntax but im just learning english :p)

I downloaded Zbrush 4 Trial and im having Geometry and quality issues, for example when i Zoom in a sphere or the rhino model (the one that come with the program) i can see a lot of pixels and i see a very poor quality. And the biggest problem is when i draw with some of the brushes like the standar just make a lot of squares and the quiality of the brushes is very poor when i try to draw some small details.

I own an Asus N53s notebook with
nvidea geforce gt 540m 1 gb
4g ram
intel i5-2410M GhZ
Windows 7 ultimate

Just to make a reference i can play games like Skyrim in Hight without any visual problems so i wonder if this may be a requeriments problem or another thing…

PD: This is not happening with Sculptris but in Sculptris my pc is very laggy and i cant model anything

Thanks u very much c ya.

It sounds like you are using zoom instead of scale to make your model “bigger” in your viewport. This is the same effect as zooming into pixels inside of any image. You want to use scale (on the right shelf) to increase your size.

Mesh resolution is dependent on your subD level. At very low subD levels you will see hard edges on everything, at higher subD levels it will appear smooth unless you scale up very far. If you’re getting hard edges when using the standard brush then you need more subD levels or more localized geometry in the location that you are trying to add fine details to.

Hope this helps.

Yeah that’s what it sound like to me as well. There are two different scale buttons and one zoom button in the default UI which is probably very confusing for new users. Each works differently and is something one should really spend some time learning.

The other problem regarding the standard brush and squares sounds as if he is, after running ZBrush, simply painting from the get go without doing anything else. If the standard brush in the upper left is grayed out, and the SimpleBrush tool is selected in the tool palette (upper right in the default UI), painting in the viewport will result in lots of overlapping squares. This is because it’s using the currently (un)selected alpha to paint 2.5d pixols. Pixols are something else new users need to spend some time learning. Try choosing a different alpha and then paint some more. It should become clear what is happening.

If you want to work in 3D, first select a tool (Cylinder3D, Sphere3D, Cube3D, and so on for example) in the tool palette, draw it onto the canvas, turn ON the edit button (this button is very important so learn what it does), then click the Make PolyMesh3D button in the upper right of the screen. Now you’ll be able to sculpt/deform/paint/mask/subdivide/etc the 3D tool you drew. Navigate by click-dragging with the LMB in the canvas outside of the mesh to rotate the view (this is the same as holding down the LMB on the rotate button in the right-hand shelf). If you hold down ALT prior to doing this, you will pan instead. Letting go of ALT while panning will switch to proper zooming of the type you desire. Don’t turn the edit button OFF or your mesh will drop to the canvas as 2.5d pixols. If you do so but didn’t want to, clear the canvas (CTRL+N whenever edit mode is turned off), redraw your tool, and then turn edit mode ON again. If you want to save your ztool (which is what tools are technically called), just click on the Save As button in the tool palette, or click the one in the File menu to save the entire project (don’t use the one in the Document menu, it doesn’t save tools).

Ok that should get you started. I can’t spend forever typing how to use every little aspect of ZBrush though. Read the included documentation, consult the official Wiki, always do a forum search before asking a question, and also do a search on Youtube where you’ll find many helpful videos for beginners.
