I have some D5 render assets and I would like to know if I can put them all at once in D5 render?
D5 Render Assets cannot be exported outside of D5 Render. Are you perhaps talking about models from other 3d Modelling software? Please clarify.
You can select all of these models then import them to D5 Render but you will have to individually select these models inorder to be placed in your Local Library.
