What is the difference?

[Mr Z]

Hi everyone, I'm working on my very first model and I've ran into some problems which make me start all over again, however now I'm in the habit of saving.

I just want to know what difference does it make whether you model in 640x480, 1024x768 or 3000x3000 etc :qu:

you model in that size then it will EXPORT in that size you can't really tell when its in zbrush till you export it

heres what i do ... first i use the default size .. i create my model.. i clear the layer and up my canvas size doubling the size that i want my actual image to come out to... ex.. say i want a 1027x724 image size ..all i do is double that depending on how clear i want it to come out to... then is use the texture master to texture my model...and finally after i get the image i want i just resize the entire image to the specified pixels... hope this helps... a good rule of thumb being the larger the doc size the cleaner the image or texture but it can take a toll on your system...

So Basically the higher the res, the better the quality.

thanks to you both, great helping hands :tu:

you got it...this called dpi.. dots per inch..the more dots the better res..

Actually, it's not DPI. ZBrush always exports at 72 dpi. However, your canvas size does greatly affect the amount of detail that you can squeeze into an image. A canvas 620x480 gives you 297,600 pixols to work with. A canvas at 1240x960 (twice the default) gives 1,190,400 pixols -- four times as many. Four times the default would be 16 times as many.

But it also means that more processor power is required. While that isn't usually a huge matter in paint mode with only a few layers, it can get to be a huge deal when in edit mode because the computer has to deal with the object at that point in three dimensions. This is why it's best to do as much modeling as possible at the default size, and then go from there.

In fact, it's usually easiest to lay the main elements out at the smaller size, placing a marker for each one. When you have all of them placed, then clear your canvas and enlarge the document. When you use the markers to redraw the objects, they spring into life at the scaled up size, without any worries about them switching to wireframe as you try to move them into place. Then you can finally start adding your smaller objects and doing your 2D/2.5D painting.

A good rule of thumb for canvas size is to create your image at 2 to 3 times the size what you have in mind for your final product. Then in Photoshop increase the dpi to 300 without resampling, followed by resizing the image down to your final size. This give great antialiasing without losing a lot of detail.

Hope that helps!

Thank you everybody, especially Aurick who really made that simple explanation worth reading.

I'm certain I wont have anymore questions about Resolution again :D
