spline problem (i dont know what to delete)

This is one that you "should" see deprecated versions of, because of an anti-aliasing issue with gl-spline (I think?, hard to remember). It allows you to use the older version of the patch. You do see the new version too though, right?

Not quite:

The deprecated versions are stubs for the new versions -- internally, we changed how the GLTools patches are identified, and we had to keep the old ones around to ensure backwards compatibility with old compositions (otherwise, it would give errors, and you'd have to renoodle everything).

Those are completely normal, and using them actually doesn't hurt anything -- GLTools is smart enough to only create new ones even if you use the deprecated ones, so nothing obsolete is ever created. (a couple other patches do this too I think, but GLTools is the most prolific)

yeah, but the spline now making me crazy. Its lost their curves. Like when you pull the subdivisions to a low number. But in my example its 200.

check the actual values, restart QC, restart the mac (in that order) -- there's a really subtle bug in the spline that causes it to forget its values sometimes (Not sure how it works, it gets reported every few months, but I've never been able to reproduce it).

If it forgot the values (nan, or huge, or whatever), you have to regenerate them manually.

its ok. The values are... i attached a shot. So i changed the spline, and now is working normally. Summarizing, the problem is identical if you duplicate or copy splines. Normally the next question should be, there will be a GLspline structure... But iam shy to ask it:)

thanks

From looking at those values this looks similar to the problem I had where the spline patch would randomly change the values entered into it.

Spline Patch Value Initialization

So, reports of the spline freaking out go all the way back to like late 2007 (!). I've never been able to reproduce it, but more than a few users have chimed in to note it happening under mysterious circumstances that I was never able to reproduce.

This week I've been going over GLTools 1.2 with a fine-toothed comb for release friday morning, and I am pleased to announce that I've Finally found this bug, reproduced it, and, most importantly, fixed it.

Holy cow, that was driving me crazy all this time, and now I can lay it to rest (and work on other exotic bugs :)

nice work, and here is a new screenshot from 1.2.

cool -- under what circumstances did that happen?
