Hi! Friends, thanks a lot for your replies!
But I have a comment:
How do you copy texture projection? (Multi-lister>edit>copy)?
When I copy a texture projection, shader is also copied. It's not a problem, if I have two or three copies. But in case with 50 object's copies, shader will be copied also 50 times. (image with bottles - here I used "convert to smear")
PS. I've tried to use "link with object" in "3d placement" tools, but it doesn't work in this case... (image with spheres - projections are copied to the instances, but doesn't take effect)
best regards, pozdeev
