Hi Dr Sassi, thank you so much for your response.
In the end what I did was rebuild the Redshift texture I was using as a legacy texture instead.
I then linked this to a Displacer deformer on the object (selected displacement option), to create real geometry.
I am curious though, in future is there anyway that I can do this with a Redshift texture (because it's rather inconvenient to have to rebuild as a legacy texture!) Initially I tried with the Redshift texture but it didn't work, am I missing a step?
Thank you
Mars

Hi there, I have an object to which I applied a material, projection mapping is spherical.
I need to 3D print this object, and so I need to somehow convert the texture (as rendered) to actual geometry.
How can I do this/is it possible?
