Downloaded Demo yesterday. Want to use program to produce images for TV commercials. Can anyone tell me the max dpi you can achieve with ZBrush? Haven’t come across this info in tuts or manual yet - thought it would be quicker just to ask. Must produce images of at least 600 dpi.
Please help. Thanks
in which size do you need the pictures? (inches,cm…)
maximum size of document are 4096x4096 pixel
–> 600dpi by ca. 6,5x6,5 inches
this thread will help you http://www.pixolator.com/zbc-bin/ultimatebb.cgi?ubb=get_topic&f=1&t=000516
but zbrush renders with 72 dpi and i think max 4096x4096 pixels ?! hope i m right
for me i make pics with this and get 600 dpi in other progrs like Photopaint or PS -you sure make postwork( although you have many tools in zbrush for this) but for a test print…
Thanks for your help guys. Images for broadcast need to be at least 600dpi for viewing on any size screen without image quality loss.
If you are correct & only renders to 72dpi, then images are only good for display on computer monitors or very small print.
What is the good of amazing paint effects that ZBrush offers, if you have cover them up with Photoshop paint to achieve quality output??
Guess I won’t be buying the program after all. So disappointing.
Thanks again anyway,
Cat.
which 3d prog renders at 600 dpi?
if you use 4096x4096 its really printable in any form - and scaleable without losing to much “quality”…
I don’t think you understood the postings, you must work with the higher canvas sizes to get to 600 dpi.
Most people do postwork in photoshop or photopaint.
You can’t do this with the demo, ie resize the canvas.
It would be a shame if Zbrush couldn’t do high resolution renderings, but you can… You just downsize your images.
Thanks again guys - this is fun.
I use Electric Image Universe for 3D animation, to produce film quality movies.
I don’t know myself how print quality translates to broadcast quality, except that images must be at least 600ppi, preferably higher, I guess to accommodate TV screen interlacing & screen size anywhere between 58 inches & the new wide screens - not to mention cinema screens. You’re right, it’s a shame the demo won’t allow me to experiment with this, otherwise I could burn images to DVD & see how they look on telly.
If you have any other suggestions, I’d appreciate it.

The DPI Script will calculate for you the size that any image should be in order to be able to achieve a desired resolution.
Also, how many times will you be directly using ZBrush images on the air? From what you’ve said, isn’t it far more likely that you’ll be using ZBrush-created models and textures? If I’m right, then DPI doesn’t matter an iota for the model. As for the texture, I have never heard of one being created at 600 dpi. Usually, they are 72, 96, or 150 dpi. This is because the animation package handles rendering the final dimensions and dpi. Let’s face it – for most animated characters, a 4096x4096 texture at 600 dpi would be serious overkill. The general rule of thumb is to use lower resolution textures, and only switch to a high resolution texture at a point where you are zoomed in very close to the model. So for example, a human figure might use two 2046x2046 textures – one for the head and one for the body – and each is at 72 dpi. When the camera zooms in for a closeup of the head, then the texture would be switched to one that is 4096x4096 and still at 72 dpi. Such a texture is generally considered photorealistic. If the camera were to zoom in even closer; to the eye, for example; then yet another texture might be used for just the eye and the area around it.
In short, it is a much more efficient use of your computer’s resources to always use the lowest resolution texture that your scene will still look good at, and only swith to higher resolution when necessary – and then, only in the areas necessary. So a scene rendered at HDTV dimensions and 600 dpi resolution might very well be made up of two dozen textures ranging in size from 512x512 to 4096x4096 – and not a one of them over 72 dpi.
I hope that makes sense. And helps a little bit. 
PS: I’ve done some checking, and the high definition (1080i) format, which is currently the best that television can display, is recorded at a resolution of 1920x1080. Therefore, a ZBrush image created at 4096x2304 will look great on an HDTV screen.
Thanks Aurick,
This does make sense, & I am relieved, as ZBrush offers the easiest & most effective tools for modelling I’ve seen.
You have done the research for me, & I’m very grateful.
Here in the “lucky country” novice animators have the opportunity to produce TV commercials, when they have been in the game only 6 months - I’m working on my 5th commercial now & really want to make the jump from 2D to 3D. ZBrush & helpful people like yourself, may make this possible.
A thousand thank you’s.
