Lightbox alpha to brush alpha?

ZBrush Usage Questions
#1

Hi,

This seems a stupid question but I have some alphas loaded in my lightbox instead of the zstartup alpha because this gets slow. When I double click on an alpha though Zbrush puts it in the texture channel of my brush. How do I get it in my alpha channel of my brush? Clicking “make-alpha” of the texture palette seems to change the alpha but I can’t be sure how it would like if I load the image into the alpha directly.
How do I get alphas from lightbox directly into the alpha channel of my brush?

What file format are the problem alphas in?

For ZBrush to recognize them as actual alphas, they should be grayscale PSD files. If they’re JPG or if they’re RGB then ZBrush will load them from LightBox as textures regardless of which folder they’re placed in.

Just checked, they are all PSD but not grayscale. Converted them in photoshop and it works now.
Thanks!
