ZBrush Usage Questions

Hi.

First time I have used ZBrush in about 2 years (I’m very ashamed to say!), so my first modelling in two years, and I’ve forgotten more than I have remembered! (BTW - ZBrush 3 is awesome … Thank you! :smiley: )

Anyway, whenever I switch to ‘Best’ Render, I get horrible harsh ugly mottled shadows. I am using the render settings on their default values, and the default ‘Best’ settings in ZB2 gave better results (if memory serves), and I just wondered if it was something obvious and/or am I being dim?

Thank you.

Increase your number of light rays under lighting and they will be much better. Aperture plays a big part in the softness of the shadows as well. I would play with the various settings to understand better what they all do.

#3

Go into your Lights pallette and play with the Shadows settings.

Specifically, increase the number of Rays. Default is 1 – try 120.

I find that I also like to increase the Aperture and Length to about that same amount, but your mileage may vary. (I recommend hovering the mouse over each of those settings and holding CTRL down to see the description of how they affect things.)

Yeah it’s a weird thing that Zbrush does with the best-render thing.

What you’re looking for is in the Light->Shadow->Uni

Pull the Uni up to something higher then it is and see how it renders. That should fix your problem.

Thank you guys for all your (EXTREMELY QUICK) Help.

Hi Everyone, i’m also experiencing this issue while rendering, i have tried the changes which does indeed fix this issue, but its a pain changing it every time though, is there anyway to make zbrush save this setting as a default, i’ve tried saving the default config but this doesnt seem to work, any pointers?

Much appreciated.

Cheers
Paul

Easiest solution is to record a macro, and CTRL-drag a button for it onto your interface somewhere. Then your pain is limited to one button press.

No need to record a macro, just save out the Light set up from the Light menu; the shadow settings will be saved too.

To have the setting load at startup (without having to load the lights), save the document as StartupDocument.zbr in the ZBrush3\ZStartup folder.
