I haven't downloaded your model, but usually when I run into 5 pointers "not taking": I select the 5 cps, then hit "." twice (to deselect, reselect). Green Donut should show up. When that doesn't work, I select the 5 cps, hit "hide" so only those cps show, then reselect (with lasso, etc). Donut should show up.
Good pointers! In this case, that didn't do the trick, but that is definitely something I will use!
However, what I am noticing on your model is a reluctance to use hooks for ending splines. I usually reserve 5 pointers for those places where I want to "extrude" an appendage, ie, change direction of the patches, or the 5 cps are not co-planar. You have situations where the 5 cps appear to be co-planar, and in those situations it might be better to use hooks.
There are places I tried to use hooks, and the geometry went crazy - all over the place. So the next solution (short of creating a three triangles or a triangle and a 4-point patch) was 5-point patch. I think hooks work better where there is a relatively flat or regular area where you are trying to reduce the spline count, i.e. in a cylinder as you get away from the main body and don't need higher spline/patch count for smoother joints (example in TECHREF.pdf pg 54 Hooks). The places that I considered using them on this model were either in a tight area which resulted in the crazy geometry or was on a curve and resulted in too flat a surface where there should have been a curve.
Perhaps (or likely) I'm not understanding 100% which places you are meaning. There are 2 5-point patches in the images I posted ... one is the one I mentioned, the other is on the other side of the spline towards the hood area and the windshield.
One thing I realized is that the spline that goes from the base of the windshield to down by the mudflap is a single spline. Technically there were not 5 separate splines with those 5 CPs. I broke it, made it a separate spline, then hooked it back together, and I was able to create a 5-point patch (using the hiding trick you mentioned above). The description in the TECHREF "Make Five Point Patch" pg. 266 doesn't specify this limitation, though. That solution works (and maybe will help out in the future), but if you have suggestions for better splineage, I'd love to see/read them.
Perhaps I would have been better off with this kind of splineage (see images), that is, if the hook would have attached anywhere near the right place. Or is there something else?
I made a 3rd choice that just used more splines. This seems to give a reasonable result after playing with the spline handles a bit, and gets rid of the 5-point patch in question. It's image #3. (I see I have an inconsistency that I will have to fix which is on the other 5-point patch that is in there, but I should be packing now for vacation.) Is this the best solution?
I'll probably be skimming the forums while I'm on vacation, but not animating.
