No apology necessary just a tip.
It’s worth noting that since a material is applied globally to the outside of a container, that is to every surface, you cannot right click and edit or move a texture around on a face. So if you want to apply specific textures and then scale or position them on a face you will need to paint the surface inside the component.
This might lead to some confusion when exploding. Say you painted a component on the outside with that nice wood material you were using in the first post. The whole thing takes the wood grain in one click, so far so good. But then one side does not look quite right, you want to scale the material a little and position it, you right click on the component, no option for texture. You open the component and select one face, right click, still no option for texture (because the material is on the outside, and the inside face is actually default).
If you explode the component, the materials applied to the outside, resolve onto each individual surface and suddenly the option to edit a texture reappears, because that texture is now applied directly to the surface.
A way around this is to open the container of the group/component, go to the surface you want to edit and sample the texture on it then immediately re-apply it, thereby moving the material from the outside to the inside now you can right click and edit. There is also “make unique texture” which allows other options.
It can get confusing, generally I use the outside for all solid colors and often need to paint the surfaces inside a component for textures that I want to be able to position precisely on each face.
