Hi All
Question: Is it possible to “clip” a decal in 3D in order to limit it’s influence on the object in other ways than “forward” / "backward?
I wish to add a decal with the “ekko”-logo on the INSIDE of the room WITHOUT applying to the outside of the opposite (U-Shaped) wall. Similar with the larger logo on the wider wall with the larger logo.
I solved the latter by detaching the opposing wall and thereby avoiding the U-Shape. The sliding doors have two different decals on either side. It is OK just to attach two decals (one on either side) on both doors, but it would be much nice to have a “Decal Symmetry=On/Off” toggle 
Check the “Named Views”, “Named Positions” + “Snapshots” for easy reviewing different scenarios.
Kind regards Tim Elkær, Erazmataz@gmail.com
P.S.
None of the decals (added in Rhino 6.0 SR31) are translated when
using the newest version (Dec. 2020) of KeyShot 10’s “LiveLinking”.
