5 point, trouble patching

[wildcard]

I'm having some difficulties with 5 points and turning them in a 5 point patch.

Either i'm doing something wrong (most likely cause) or have a problem in my model that that I'm unable to spot.

 

From what I know, to create a 5 point spline you need 5 splines connected to one another forming a closed loop.

 

 

This is a portion of a hand, or where the fingers meet the hand. 3x 5-point patches between each finger on each side of the hand.

 

A few of those 5 point patches are not working. I got 5 points selected, but the button remains grayed out.

Normally, I select the 5 points by manually click on them one by one. If the button fails to light up, I hide every thing else except for those 5 points and drag a selection box around those 5 points, frequently this works. Every now and then I simply can't get them to work.

 

 

What makes an invalid 5 point patch?

I would not use a 5-point-patch for the dead-end-spline. That one is perfectly suited for a hook. However I would although try to not set the hook next to the 5-pointer but try to set it a spline-loop away from the 5-pointer. That should solve the problems you are having there.

There's probably a similar dead end spline on the other side of the hand? I'd just continue them to meet in a CP in the middle. You won't be able to use a hook as a side of the 5-ponters that are already there.

 

However...first trick to try to make a five pointer... select all 5 points, then hit the period key twice.

second trick: select the fivepoints, hide the rest, select the fivepoints a new and in most cases the fivepointpatch-tool turns active.

(Edit:Just read, that you already know that trick....)

 

if everything fails, try disconnecting and reconnect some of the cps a new, could help also. Maybe restarting the program could help also.

 

(also sometimes you have to flip normals to make the patch show, if you have "showbackfacing polygons" turned off)

Sometimes I found, when I try a few times to select the cps in different orders, once in a while the patch tool will suddenly work.

At first I tried using a hook, but the hooks looses the smooth curve the patch had, creating a nasty border along the spline where it was hooked to. I don't believe a hook would have been a valid option to go with.

BINGO! Got it to work! The problem was with a dead end spline.

Got my 5 point patch problems now fixed, will do some testing later to see what is and what isn't a valid 5-point patch now that I know its being picky about dead end splines.
