Randon Scale object settings in the 03, 04, and 05 editors..
Random scales relate to the scaling of objects to a decimal place above or below their set (default) size.
I usualy set Min at 0.8 and max at 1.2 as i find these settings are a good utility sizing for most applications.
So a 10 metre tree set to xyz min 0.8 and xyz max 1.2
will have a min sze of .............. 8 metres .........and....... a max size of 12 metres.
that means all the 10m trees will be randomly sized up or down within those limits.
If you load a 15 metre tree in the same object group its size will range from 12m to I8m.
And if you also load in a 20m tree to the same object group its size will range from 16 m to 24m.
Now all three tree objects in that object group will range evenly in size from 8 metres to 24 metres high when they are placed on the map, and they will all be proportionally exact.
Now you can also get very clever here, and uncheck the proportional box and load them like this.
Example. ( You can try other settings ).
Given that the X and Z dimensions relate to the thicknes of the trunk through the two horozontal planes, and that the Y relates to the verticle height... the trees will be scaled as tall and skinny, like those in dense stands of pine or maple, where all are climbing to reach the sun and outdo their neighbours.
But dont go overboard because the distortion will also show in the vertical thicknes of the branches and may also distort the leaf shapes
This method of resizing can also be used to lengthen/widen other objects. E.g. lengthen the span of bridges, widen them in relation to their length or make the bridge taller to reach down into a deep gully.
The only problem is that they will distort if you rotate them manually, so you need to align them by setting the degrees of offset in the position box, and clicking the set button.
Scaled objects can only be used as quick linked objects because they will revert to default size (when you close the editor ) if they are linked and you will end up with your bridge downsized and hanging about in mid air somewhere above the canyon the next time you open the editor.
But it is usefull to set large objects as linked while positioning them and change them back to quicklinked before saving.
So play around with these setting a bit and you wont have the problem of all your trees/ objects being exactly same sizes
