Grayscale Images as alphas

ZBrush Usage Questions
#1

I’ve been trying to import and use grayscale images into 4r2 and use them as alphas and getting some problems…

i.e.
lightbox displays the images as solid black thumbnails
when i import via alpha palette, they come in solid black
when i convert them to jpgs, load (from lightbox) into texture and make alpha, a substantial amount of noise is introduced (upon converting to alpha, not jpg

experiencing these problems w/ 16 and 8 bit

i’m using files that i generated and used the same way i’m trying to now in zb4

has anyone else been experiencing these problems?

pixologic, any known issues with grayscale images in this version?

please and thanks!

Try setting Preferences>Performance>PreLoad File Size to 500.

yeah boyee. thanks, marcus.

how can i get that to be the default setting? storing master config didn’t work.

the thumbnails remained black in Lightbox until i restarted.

thanks for the quick reply!

At the moment, that setting doesn’t save with the preferences.

One option would be to record and save a macro of you simply setting that value to 500. Then Ctrl+Alt+Click on the macro’s button and set a hotkey for it. That way you can press a single key to adjust the value whenever you need it.

The easiest thing, though, would probably be to edit your DefaultZScript.zsc file (found in the ZBrush 4R2\ZScripts folder. Simply open it with any text editor. Add a new line beneath the //startup line that says [ISet,5706,500]

It’ll look like the following:

[COLOR="#FFFFFF"]


//startup
[ISet,5706,500]

[pd]

Now save the file. Whenever you start ZBrush, the default script runs automatically. Normally, it doesn’t do anything but adding this command tells ZBrush to set slider 5706 (which is the PreSet File Size slider) to value 500.

thanks, guys.

i’ll adjust the DefaultZScript.zsc

should i expect to see this default behavior (PreLoad File Size set to 2 and not displaying grayscale images properly) fixed in the future or is this intended? just curious if it’s something i’ll have to address at every new machine i use or if i can forget about it after next release.

friendly reminder

I would expect that to be set to a higher default value in the next release.

good to know, thanks!
