Zbrush to 3d coat alphas

Recommended Posts

Hey, i have several zbrush alphas that i want to use in 3dc . Is there an easy way to remap the height for depth.

Zbrush is black to white depth and 3dc is 50%grey zero depth for height map .

I found this  but though if there was an easier way to do this. 

THanks in advance!

I made some test and this is what i found about it:

psd format in 3dc treats 50grey as border, png is better for alphas.

you can convert alphas in ps or gim etc with just tweaking levels output raising the black to 50 percent.

zbrush has  a slider for that job , mid value slider that changes the range of the alphas. would be cool to have it in brush options in 3dc

Also brushes that have range black zero  work fine in surface draw but not in live clay brushes. 

 

Hope someone finds there usefull.

Have you seen the videos on creating brush alphas? Maybe somewhere in there you can find out how to use your Zbrush alphas in 3dc, even if it means a lot of manual tweaking:

I am unsure if there is a way to convert zbrush brush (zbp) file type, because it contains more data than just the image itself. However, you can get the image/alphas for the brushes and import them right into 3DC without any issues.

actually i dont want to load zbp to 3dc . I m simply stating that there are issues with loading image/alphas (as is ) because of mid level convertion and live clay brushes.

Is there no average  MidValue  between 0 <- >  1 to export without troubles ?
Mid Value set the zero displacement value. If set to 1, then white is considered zero displacement and all sculpting will push in on the model. If set to 0, then black is considered zero displacement and all sculpting will push out of the model. Setting Mid Value between 0 and 1 allows you to sculpting in and out at the same time.

05 - After importing into 3DC as an alpha for use in the sculpt room.

Seems to work but there maybe issues I have not encountered yet. Your results may vary from mine but of the 34 ZB alphas I've tried it on this afternoon, I've had no issues yet.

Cheers...stay safe & healthy....

Here's another ZB alpha I converted to 3DC alpha using the above process....

The only issue I noticed is when you load the brush it looks kind of jagged. However the results from the brush in the sculpt room  are acceptable at least IMHO.
