Many of the modeling tools built into max show some kind of ‘preview’ of the changes that they will be making. Inset, chamfer, extrude, etc. all show what they will do to the selected geometry, and yet these changes are not recognized by the scene in any way until an OK/Apply button is pressed.
How does this work exactly / how can the same effect be achieved with Maxscript? (I’m guessing the answers may lie with scripted plugins, but I’ve never written one before and am not sure.)
I’m writing a tool that makes various cuts in a mesh, and currently in order to show a preview, before applying the changes, a duplicate mesh is generated for the edits to be performed on while the main mesh is hidden. Once the user commits the changes that temporary mesh is deleted. However, this results in two copies of the mesh in the scene at the same time, which is far from ideal.
if you temporally create just a mesh it’s absolutely OK. there is nothing wrong with it.
but if you create a node…
do you want to show both – original and preview – meshes at the same time?
