Moho Animation Forum

I have been using this software trying to learn the ropes of rigging for a while since there are very few tutorials I am having a hard time finding many solutions. I am working on a show where some of the characters if I put them in one file it becomes very laggy . Cant work or animate at all. I cant seem to find out why this may cause or how to solve it. i am adding a dive containing 2 of my problamatic riggs and file why it is lagging alot.is it because of the rigg or any kind of hardware issue. need some insight . i added the files for with the rigs and a shot containing some of the characters.

The shila file has keyframes in the negative timeline (known bug).
You can find my menu script to fix this here: viewtopic.php?t=32714

Thanks alot.i used the script to delete the negatice keyframes.it is still quite slow and laggy.is it because of the many layers and textures? or some other reason.some of posts suggested that bad shapes with many points can cause this.i am unable to see anything. is the sheela character slow in general.

Shila's body bones have serious issues, while Chiku's intelligent bones have some problems.
This is the only reason that causes lag.

I've analyzed your character. I had a similar problem and it drove me crazy because the program was very slow. I think the problem can be the combination of the target bones with the leg bone angle constraints. You need to disable the leg bone angle constraints (both bones and both legs) or change the values. Try it and see if it makes things run more smoothly.

I just saw this, and wanted to share a thought: it's probably not a good idea to have more than one bone in the same bone chain pointing to the same target bone because...

1.) It's not necessary because when one bone is targeting another, IK will automatically rotate the 'in-between' bones to follow its child bone. And...

2.) If more than one bone in the same chain is targeting the same bone, a conflict may be introduced to the IK system.

So, try targeting with only the bone at the end of the IK chain.

FWIW, I've never experienced a slowdown due to bone targeting, but I've never tried setting multiple bones in a chain to point to the same target bone. Right now, the above is just a theory, but I'll try it today and see what happens. I really wouldn't be surprised if it slows things down.

Bonus Tip: Sometimes I'll use an arm's IK chain and a target bone to pin a hand to a static object, such as a tabletop. To do this, I'll set the lower arm bone (not the hand bone) to target a free-floating bone on the tabletop. I'll also set the hand bone to use Independent Angle...this will effectively 'fix' the hand bone's rotation to world space so it stays flat on the table while the rest of the body moves. Variations of this technique are useful in many situations where a character needs to interact with their environment, other characters, or props, or for planting feet on the ground.

I only use this technique in special situations for the arms (i.e., pinning a hand to an object or 'locking' a hand to the hip), but I almost ALWAYS use this technique for the feet. It's much easier than using the Lock Bone method.

Now, if only the Independent Angle option could be made keyframeable... (hint, hint.)

I've checked the character again (shila New) and you're right. It has both leg bones linked to the same target bone. But even when I unlink the first leg bones from the target bone, at least for me, the character still runs very slowly. And if you animate the character and duplicate it, MOHO freezes completely.
After disconnecting the leg bones (B15 and B17) from the target bones, try to animate the character's main bone (B4) and then moving the target bones of the feet. Try animating a few keyframes. The timeline becomes impossible to animate.

I had some characters where I didn't have to turn off the bone constraint angles. Just changing the bone constraint angle parameters stopped the slowness. It usually happens to me with characters that have many bones with actions

I don't know if I'm doing something wrong, but I've been using MOHO for many years and this has never happened to me before.

I have to say that I'm not currently using any scripts that could slow down the program. Since I had the same problem and couldn't find a solution, I reinstalled MOHO, thinking it might be an external script.

And thank you for the bonus tip. I'll try it.

Hi negroclarito,

Thanks for following up! I reread your earlier post and had doubts that my theory had anything to do with your situation. But I'll still test it here later today and see what happens.

Let me know if you figure out the cause of the lag. I like to keep track of issues like this, in case I or someone else runs into them.

I'm not an expert and I have a lot of issues myself that I solve but I noticed that a lot of your smart bones are parented to your main bone "B4". This may or may not be the issue but if I were you I would create a bone that's not parented to any other bone and parent all my smart bones to it. I call it my "follow bone". Whenever I need to move my character and move the smart bones either I parent my "follow bone" to my "main bone" or I don't parent it to anything and parent my smart bones to it and move it accordingly/manually. Also with some of my characters I turn off SHAPE EFFECTS AND LAYER EFFECTS when I animate. It makes the program run faster for me. Also you had alot of negative keyframes. There's a scrip called SYN: NEGATIVE KEYS. It removes negative keyframes. I hope this helps. All I can do good is animate. I'm not a scripty, techy Cat with all the answers. I just figure it out as I go. Also GREENLAW helps me alot. Listen to him. Trial and Error my friend.
