Hi,
I propose 13 euros for two minor modifications of the following script.
https://pasteall.org/blend/36550524d41e41a39432633b296ecb4d
It allows initially to create 3 separate cross-section using the cross sections planes X/Y/Z on any object.
I added three new planes (-X/-Y/-Z), and custom properties for them, then I adapted the nodes in the material and still have two problems:
-I need to multiply the effect of the two last planes with the others
-I would like the script to create only two buttons: one to activate/de-activate the cross-section effect, and another to invert the direction of all the cross-section effects at once.
