The rescale world units tool shouldn't only have a spinner to enter a scale factor.
There should be a 'to' and 'from' drop-down that lists all of the units available in the max system units dialog. I.e. if the current system unit is mm, and you have imported a model in inches. I should be able to select inches in the 'from' drop-down, millimeters in the 'to' and have it know the correct scale factor . Every time I have to manually figure out the scale factor myself when max could easily do it for me and I dread using it incase I get the factor slightly wrong.
It would be great if it had the ability to apply the scaling to only selected objects and it's modifiers and all values within them for things like hair and fur too.
The tool could easily be made with maxscript (and likely already has) but would love it to be a first party solution. I always dread having to use the tool as it stands.
