Thanks, that helped alot, in particularly due to the ability to simplify the inset geometry (reduce backside) and by percentage of the simplification.
The other work around was to use poly extrude with a negative distance and Output Back checked.
The ‘Labs thicken’ works slightly better then a regular extrude, but the real life saver here is the '
reduction percentage', which is actually exactly what i needed in this instance. (simplifies the geometry to prevent it from insetting on itself, allowing greater thickness, and is also just good if you wanted a simplified version of the geometry anyway)
It still thickens some proportions unevenly though, causing one area to be thicker then another and causing weird angles to form. Which would require cleanup or in certain instances might not work all together.
The other downside is that for some reason you cannot use this thicken operation on groups.
The geometry i'm doing this on is already merged with shapes that have other operations performed on them, so I have to delete the old version of my object and re-merge it with my new one. If I had made any changes to my new object prior that would mean having to cut out the rest of the gun model to isolate the portion i need to work on aswell, unless there is a node that can separate geometry based on groups or fetch specific ones then output it?
