Quick question here, just recently i downloaded vray to give it a try and notice the assets from vray cosmo are resizable just by using the transform tool. The corona version is not resizable, at least on my machine either on mac or windows. The only way to resize the asset is by converting to mesh. Also notice on the video attached that it is very possible to resize by using the transform tool.
Switching from Model mode to Object mode works for me. The only downside to scaling this way is it doesn’t affect any instances if you rescale after creating the instances.
Can you not put the proxy inside a null and then instance the Null (pressing ALt+G to match the proxy coordinates)?
Then when you rescale the proxy (preferably with the scale tool in object mode), the instances also follow, keeping their individual scale settings (p.e. when you applied random scaling with the c4d randomize objects tool…?
We work like this since… well, ever…
in fact it has become an unwritten rule here in our office
it also provides possibility for other quick adaptations to all instances for offset moving /rotating the instances and adding suick details such as ground spots for trees to name one…
