I have a question, I am learning how to build scenes from the training video. He is using Daz3d4.5 but in his content library is using props from DAZ studio 3. How can I use the same content library he is using to follow him.
DAZ Studio 4.5 can read your DS3 content folders, if that is what you are asking?
Go to Edit > Preferences > Content Library > Content Directory Manager, and enter the path to your DS3 content folder as BOTH DAZ Studio and Poser Formats.
If your Content is installed in just your DS4.5 folder just use the Content Library Tab and you should find the content in the same Poser and DS folders as long as you have the same items installed.
Thank you very much for your reply
