Some thoughts about translucency. When adding a color adjust and saturation control on a surface layer, the translucency of the original default shader is lost. Luckily there is a workaround by adding a new Lambert shader. That's one.
Two: when loading or reloading an object (see screenshot), it won't replace the original or old object. Workaround; just delete the object from the pop, rightclick, then load it freshly, re-attach, and repopulate.
