I am noting that when i load a environment it seems like the scale is off compared to my characters. it seems like a room that i load is much bigger that what the adult would sit in. is there a way t change the scale of a room when load it?
One way to accomplish it would be to use the "scale" parameter.
It's going to depend on what environment asset you're using but good ones will come with everything preloaded into one or more groups. If it doesn't, just create a new group and place the nodes you want to scale inside it. Select the group node and set the scale you want from the parameters tab.
