I think we covered this somewhere in the 569 prior posts . . somewhere. In short, using the morph function in the animation/trick-film requires the same number of points between the two frames to have it go smoothly. Point 1 of frame 1 becomes point 1 of frame 2, point 2 becomes point 2 and so on. What I've done in the past to make for a smooth morph using this function is to copy your first frame to the next in Quickpicedit and manually drag out the points one by one into your destination shape and so on if you have multiple morphs planned.
If you aren't artistic, there are a number of tricks you can employ to make subsequent frames look like you want including copying the desired picture on top of the copy of your first frame. E.g. if you wanted to morph a circle with 50 points into a square, copy that circle to the second frame, then draw a square (or copy one from another frame and paste it on top of the copied circle in frame 2. Then drag the circle's points out on top of the square that you just pasted in (or drew manually). When everything is lined up, delete all points after the first 50 using the Active Point Editor or manually selecting them and hitting delete.
Another approach is to use bitmaps sitting in the background of PicEdit (which comes with the Basic and Pro versions) and manually dragging a copy of your points from the first frame into the desired shape of the second frame. The trick is to make sure you have a more than adequate point count in the first frame to accommodate the second, third, etc. frames that you want to morph into.
All of this said, this approach isn't how Swamidog or other 'abstractionists' typically morph between shapes in a show. Even after years of in depth show creation, there isn't a single one of us that knows everything about LSX. This will sound cumbersome, but if you haven't already, I would suggest reading the entire LSX manual and associated PicEdit manuals that came with the program from beginning to end . . two or three times. I would also read the LSX Living Manual, watching all of CMB's LSX tutorials and the LSX tutorials recorded at SELEM which are available on my Youtube site such as this one. This thread is also great reading although very long. Oh, and have fun playing!
