Moho 12 Bugs

[KuzKuz]

Moho 12 bugs:
1. Smart dials break bone structure.
2. Curvature goes crazy if used in mainline with smartbones.
3. The Freehand tool creates excsessive loops at acute angle corners.

1. Creating a smart bone dial of a parented bone has always set it up relative to the parent bone's rotation (exact same behavior as AS11).

Freehand does not do that for any of the tests I did ( just now I double checked), it was clean and good, one nicely pointy bezier at each point no excess no mess.

Are you drawing with a mouse?
Try drawing freehand with a stylus.

Wow, that's really weird stuff but I'm not seeing any of that here.

Last week I created a character at work that used nearly 50 Smart Bone Actions and these Actions all worked perfectly. Some dials were created using the 'Make Smart Bone Dial...' command, but I stopped using this command for creating dials because it doesn't work well when the bone is parented to another bone. I typically have all my bone dials parented to a common 'mover' bone, so it's better for me to make my dials manually. No biggie.

As for the extra knots at the peak, I tried to reproduce what you're getting using a mouse and a stylus but it's not happening here. At the moment, the mouse and stylus are drawing the way they should on my gear. I checked it a few minutes ago on my Cintiq Companion; I'll give it a try on another computer later.

I'm not doubting you--obviously something weird is happening on your end. I'm just saying I'm not able to reproduce those errors here.

Could you post the scene maybe?

Thanks for feedback. I use wacom intuos tablet, but mouse give same result. I recorded video with step by step recreation this bugs.
Moho File

Curvature bug only if change curvature value with mouse drag on point. If type value in Curvature value field then work fine.

[Greenlaw]

I tried to recreate your scene and the curvature control with mouse or stylus is working as expected here. Could you post your scene? Maybe I'm doing something differently.

Also, have you tried this another computer? Just wondering if it could be machine specific.

I will try use another computer later.

I tried the file and get nothing like what you are showing in the video KuzKuz, I can't imagine what the problem is , all fine here.
SOrry I thought I had an idea before I got the file but all is working on this end.

[KuzKuz]

You try use curvature tool in my scene at first frame too? Wow, i don't know why only i have this issue.
Maybe someone knows what reasons can be?

[synthsin75]

I can see your #2 problem here. Seems beziers used in smart bone actions have unpredictable results when you try to animate curvature on top of them. If you just change the curvature, without changing the bezier handles, in the SB action, you'll be able to add mainline curvature and bezier on top of that just fine. If you use the beziers in a SB action, it's best to avoid adding curvature or bezier in the mainline, for now.

I'll report the bug. Thanks for the file demonstrating it.

[Greenlaw]

Wow, that sounds tricky. So are you saying that, for now, we should just pick one method, curves or bezier, and stick with it? For the most part, I'm still using only the curvature tool in Actions and out, which is probably why I'm not seeing that.

Anyway, good job figuring that one out!

[funksmaname]

A bug well found.

Greenlaw, it works as expected as long as you dont try to add bezier handle adjustment in the mainline to handles already influenced by a bone - if you don't do any bezier correction outside of an action (for affected points) then you shouldn't see weirdness...

[synthsin75]

Yep. Either use beziers ONLY in a smart bone action (no mainline curvature or bezier added), OR just do curvature in the SB action so you can still add beziers to the mainline.

[funksmaname]

problem with that is the effect of compound influences can't be corrected (such as squash/stretch bone adjustment) - I think this needs swift squashing!

[Greenlaw]

Ah, thanks for the clarification guys! I'll watch out for that.
