If it is a template, it is basically to open the audio and video first, and then click File-open the project and find the VSP file of this template you downloaded. If it can be opened, the template is good. If a black and white bar appears after opening, it means that you need to re-link. As long as you open a part according to the file name, it will basically be imported. Of course, you can also send it to me to see what 3D looks like.
