Splines have shapeshifted

[detbear]

It seems like the spline architecture has radically shifted. I've been noticing

strange weirdnesses over the last few updates and it seems that they don't

behave as they once did.

 

I tried to simply combine two splines on my most recent model and the bias handles

remain separated for some reason on each side resulting in a "peak."

 

This is not ideal if you want a flowing line.

 

Attached shows the splines/ bias....before and after joining.

 

 

 

 

This is very weird.

In a quick test I can't duplicate that result unlessssss...

 

...perhaps there is a hidden spline segment on the end of either of those splines?

 

The curvature of that top spline suggests there is more on the end of it.

[robcat2075]

Other possibility... one or both of those spline ends has been set to (P)eak inadvertently.

[robcat2075]

When joining two free CPs, the new CP inherits the Peak/SmOoth property of the one that is being manually moved.

 

If you drag a Peaked CP to a SmOoth CP and attach it the new CP will be Peaked

 

If you drag a SmOoth CP to a Peaked CP and attach it the new CP will be SmOoth.

Hey RC,

 

Yes....i looked into those things and didn't find those to be the case. However,

I am woring with an obj import and had used the snap feature. Still......if there are

two cps there, selecting them individually and erasing or adding a new spline should've

resulted in "smooth" bias.... but it had that weird result.

 

I erased the spline and ran a new one all the way across. The new one worked better.

 

Another new shapeshift in the splinework is that when you add a cp, you no longer can

easily pick which side it's going to appear on. the splines seem to be more locked to a direction.

Send me a sample of the model that has the problem and I'll look at it.

So far, I haven't noticed a problem when I've been adding CPs and I do that quite a bit.

What happens when you select and hit the 'o' key?

[robcat2075]

I suppose it's possible that in an imported OBJ the property of Peak/Smooth is somehow being written oddly.

I believe Kevin did say he had used the "snap to surface" feature with the imported obj, when laying down new splines. My guess it would be the "snap to surface" that is possibly creating the problem.

 

Hard to tell from his description of his process.

Example B is mysterious. The double bias handle will normally only show up when there is a spline on both sides of the selected CP. That's what makes me think there is a hidden spline segment there.

 

 

 

 

[detbear]

That puzzled me too. But at the time I couldn't see, click on, or unhide anything on the other side. It was like

something invisible was there and locked.

 

Good news is....I got rid of the spline by running another and that solved things.

 

Honestly, you never know what's going to happen under the hood of an imported obj... They can be very deceptive. Often

having two or three splines on top of each other with no visible indication.

 

Thanks for thinking through this a bit with me. It was a real strange thing. It almost felt like I was clicking two cp's at once with

one of them being invisible and unselectable.

Without a sample project I can't say what's going up here , nor fix if this is really a bug ...
