Introduction / Document Resolution

Subtitles of the Movie

Okay. In this movie, I want to cover Document Resolution. It's a really important subject to an illustrator, because I know there are a lot of companies out there that ask for your illustrations, and they'll always ask for the format of 300 dots per inch. So how do I get 300 dots per inch in ZBrush? So, I'm covering this before I even go into the lessons because that way, you know, as an illustrator, straight off the bat, what road you have to take. I relate better to you than I do an animator. So, Document in here. You see nowhere to type 300 dots per inch, so we have to use our brain. Okay, so I'm going to relate it back to Frames and Artwork. Works out good that way. Let's just say I have a 12 by 18 frame that I want to fill up with some ZBrush-ing thing and I want it 300 dots per inch so it looks nice. Here's a road that I take. And you can do this in GIMP too, but I have it in Photoshop. So, File, New. And I'll initially start out 12 by 18, and type in 300 dots per inch. Hit OK. So here's my 12 by 18 frame that I want to fill in and I want at 300 dots per inch. Image, Image Size will tell me that 5400 by 3600 is 12 by 18 at 300 dots per inch, so this is the number I type in. Now, do I type that number in? No. Things in ZBrush have to be doubled because we have to antialias them at the end and I'll give you an example of this. I'm just going to click out a simple cube and hit Edit. See the edges? If I hit AAhalf it actually makes the document one-half size and fixes the edges. So I have to take that into consideration when I'm looking at 12 by 18. I now have to worry about width and height. So, width times 2 of 18 is actually 36, and this is whoops, not 26, 36 by 24, okay? So, on my final render I'll make a new document that is this huge number, 10800 by 7200 and this will be a little slow in ZBrush, if I can even get that high. So, sometimes, yeah, like 1080, the 12 by 18 example probably wasn't the best thing because I can only go 8,000. So, I've 8,000 to deal with. Let me show you what I would do as an illustrator if I only had 8,000 to deal with: put Constrained Proportions on, rank this up to 36 by 24, Constrained Proportions are on. I only had 8,000 to deal with, so up in the width side of things, because I know it's going to be longer, type in 8,000. Okay! Look at that. Because Constrained Proportions is on, I have now my number: 8000 by 533. I'm using Alt Tab to do this by the way, and I have a lot of questions over that; so, take off Pro, 533 was it? Hit Resize. So, you're going to lose a little bit of resolution because I picked 12 by 18. You can actually section it out a little bit and have several renders and stitch them together, but I'm just going to go like this, go AAhalf, this is my antialias, Document Export, Export it to the Desktop for an example, drag it into Photoshop. File, Open. There is my document, Image, Image Size, Constrained Proportion, and if I type in 18 here, law states that this will change to 12. Ready? 18. Well. 11.97. Well, I was close. Come on. That's .9 something. And you know why that is? Because you actually have to render, and I'll get into that later with the rendering process, if you don't render, there are these mythical 2 pixels that exist within ZBrush right now, but it's a bug, so you'll get the actual 12 there, but that's how you do it. That's important.
