Continuing the discussion from Why can't I use the paint bucket on a component or group?:
@DaveR Thanks for OP
With all due respect, you CAN orient the materials with the control of axes of those groups or components. Although, you cannot vary them to each face. (which is expected since you are assigning texture to the group)
and you can scale them by changing the scale of those groups or components. It may not be as intuitive as material edit tool (Texture>Position), but it is possible.
In fact, I do it all the time as I find assigning materials to each surface or sides hassle as I tend to group or component each member of the project. I try to apply material to the group whenever possible.
However, I think it would be worth to talk about which is better in what circumstances
So, to the SketchUp savvy users
Is applying material on Face vs Group better?
if so, because of what reason?
It is easier and more accurate to manipulate the material
directions and scales with Texture>Position
I have noticed some issues with transparent
materials in their visibility and opacity conflicting with other
transparent materials in some cases.
as @DaveR said, you can change the material without opening the container. This can be a problem, but it can be beneficial for people like myself working with thousands of groups.
I can see that it is critical to get wood grain directions right for wood working. Also, it is equally crucial to get brick stacked correctly in architecture.
I think this would be workflow and work-type dependent methods, but as I am always interested in best practices, I would like to discuss this matter further.
