"Can't serialize empty surface"

[Jeremy3D]

I just downloaded the new version of painter.

I can't save my new project.

I get the error "Can't serialize empty surface"

What does this mean?

Please help

Looks like there is an empty/corrupted textures which cannot be saved. This blocks the rest of the saving process.

yep. that helped. would be more efficient if the error message will say it as it is. there are most likely missing textures. replace them before continuing.
