I see thanks Cryrid - seems a shame though that the xray effect can’t be applied with the insert after it is drawn out to readjust the depth on the fly without splitting it to a new subtool - using transparency to check depth then doing a boolean dynamesh?
ah ok
then later convert it to subtractive using the new dynamesh sub polygroup option.
I see what you mean by this now - strangely when I press the " Group as Dynamesh Sub" button and try it does not work but when I press the “Group as Dynamesh Sub” button then use the short cut Cntrl + W > then cntrl swipe it does.
I’m liking the advantages of this system with dynamesh groups . Dynamesh groups can be later made subtractive too > cntrl +move “w” to group mask - press Polygroups> groups as dynamesh sub > then the shortcut cntrl+w > then swipe cntrl to cut a negative. Aha aho.
Later: Ah I see having groups on is fine but once dynamesh sub is initiated to make that chosen group a negative all other groups except that masked selected group become a single group and lose their group status.
