Need help with what I'm sure is a simple setting in Aspire. I'm working on some of my first 2 rail sweeps. Once the sweep is generated I want to trim the sweep to the selected vector for that sweep. The problem is the vectors are hidden under the sweeps grayscale image. The 2 rails are visible at either edge of the sweep but I can't successfully select the vectors under it. In the Banner 3Dmod video, the grayscale sweep image looks to be transparent, the vectors are visible. Mine is solid. I must have missed something. Any help would be appreciated.
