lego-animate | Animate LEGO builds in POV-Ray

There are two ways to pick the build order. Probably the best one (and my original idea) is to generate some instructions with BluePrint, and draw the pieces in the order suggested by BluePrint. However, while messing around with this I discovered that LDD actually orders the parts as you draw them in the designer. So we can just steal that order. It's not perfect - if you delete a piece and add another one, the new one gets plopped in the order position of the original, so it can go out of sync easily. In the examples below I'm not using a MOC of mine - these are renders of the very nice Joe's Cantina by Berth.
Do not edit the build order inside the BluePrint app! It will not be respected (I rely on some rather ephemeral item IDs happening to be the same, and if you change the build order BluePrint changes them all). This only applies where you're not using BluePrint to generate the build order. If you look inside the .pov file created by LDD to POV-Ray, you'll see a line reading #declare ldd_model = union { and then all of the elements in their build order. You can just move them around (and then rerun this program) to modify that order. Each element is named ldd_something where something is the ID of the brick being used. The easiest way to find out which is which is to load up LDD and search for that brick ID. I never said this was going to be easy. Remember not to run LDD to POV-Ray again though, as it will zap your carefully crafted changes.
