Using the command line or plugins to edit part sizes does not update the shadow’s size in studio. Take this big brick for example:
use a script to shrink it to (1,1,1):
Notice what’s wrong? The shadow hasn’t changed size to reflect the part’s size.
Using command line or plugins to move this part will not change its shadow size either:
Changing the part’s CFrame or size via the default tools will reset the shadow, which is nice, but this won’t work ingame.
Note: the shadow size not changing is reflected by all size changes. Here is a large part resized from (1,1,1):
Expected behavior: CFraming and changing sizes of parts via scripts cause shadow size to update
