Can I jump in?

There are a few reasons why such behaviors, I believe cricky has provided themost likely explanation for your problem and I think I know where Stuckon3D is heading but I would like to share with you a few other points...

1) First off, for a character to continue where he left at when applying a motion segment, you need to have the ''SNAP'' feature working. The SNAP feature is automatically activated when you drag&drop motions on a given character but IT IS NOT NECESSARILY activated in the AML file generated for the persona thus right clicking on the character to invoke the motion may generate the wrong behavior.

2)I have seen many Motion segments generated by third party with the root bone left at the origin. When this happens, your character actuallycontinues where he left of when applying a new motion segments but his root bone beingleft at the origin by an erroneous motion causes him to simply continue from the origin, i.e. return to the origin.

3) If you used 3DXchangeto import/create a nonhuman character, then you will never be able to resume your nonhuman character from where you left him because 3DXchange adds a residual root bone to non-human character which always remains at the origin. I have reported this BUG to Reallusion.

Iwould not be surprisedthat one of the above is the cause your problem, mostly 2) above if youhave previously added motion that was convertedto iClone from unknown sources.

NOTE: The parameter in the AML file is called ''Sample Transform'' and it needs to be set to ''SNAP''

Hope this helps!

That was it , thanks BB. And he did say that he was using reallusion's default motions, plus I've seen this happen before when you try to go from a MOVE to a PERFORM or a PERFORM to a PERFORM move from some of the old personas. Some of the them have the "Sample Transform" set to "NONE" instead of "SNAP" Thanks again for the assist . Smile

thanks for all the replies guys, sorry I've been a while in replying. Have been away with work a fair bit lately, not much time for the fun stuff.

I shall have a look at that AML command, Stuckon3d, Bigboss
Just to clarify, the problem occurs whether I use one of the pre-set content manager animations eg turn left or the actors move commands eg move forward.

my current project where I'm having trouble is my actor is standing in front of the wheel on a sailboat steering it into shore. I've made a few minor movements of arms etc along way using the motion editor. When the boat hits shore, I've manually animated (using motion editor) the actor to jump up onto the deck - no problems at this stage. However as soon as I use the 'turn left' animation from the content manager, the actor jumps straight back to the original location at the steering wheel and then performs the animation. Likewise if I choose 'move forward' from the actor menu, he once again returns to the original position and moves forward from that point and moves forward through the hull of the boat.,,,,Crazy

update:

I just had a look at the AML file for the persona and can't find the SAMPLE TRANSFORM ?
It's the neutral persona, I've attached a link to the file below

Hi Darren,...

I added the SNAP attribute..

Load this file as an AML Persona in Dylan, then right Click, choose Move Forward from pulldown menu... Then Click with your mouse in front of Dylan, he willmove forward. Then repeat the same steps and he will continue from where he was at.

Hope this helps.

Yes, you can use this AML on any standard iClone Character.

Cheers!

thanks Bigboss, unfortunately it's still doing the same thing....Crazy
what probably further complicates the problem is the character is on the deck of a boat prop. So not only does the character jump back to the original x,y,z it then sinks through the boat onto the terrain. And because the boat moves, I can't 'add to terrain'.
I've even tried adding a path, which the character will follow right up until I add the walk animation from the content manager, then it jumps back to it's original position before disappearing under the boat somewhere....

I'm thinking the only solution is to finish the scene with the character still in the original position, save the project then clear all animation and save it as a new project and then join the 2 scenes together with my video editor. I intended breaking the movie up into seperate scenes anyway to keep the rendering time down, just means I'll have to cut the scene prematurely.

thanks to all for your assistance, I really hope RL does some work on the abnormalities/clumsiness of it's animation process, these sort of brick walls are what slows or even stops me from finishing projects. Things just don't work as they are explained in the user manual. According to the user manual, all this should have been avoidable by simply ticking the 'align motion' box. But of course it doesn't work

What you're describing, Darren, happens to me all the time, 'cos i'm not fully conversant with the Program yet.

That being said, my amateurish workaround is to:

1) Have timeline set at 18,000 frames, to give sufficient leeway.

2) Once the Character is correctly positioned, Drag the Preview Screen Timeline Left-hand slider to that position. Then all Transforms, Commands etc prior to that, won't show.

3) Trial & Error; by clicking on all Keyframes before & after the set position, Deleting those that have the Character in the wrong position.

EG; Of the above, I've  several Characters riding horses, using  Right-Click Menu "Gallop" to selected point. But I wanted Characters to already appear seated on saddle, without the Rider Mount Right-Click Operate Menu. Moving the L/H Slider cuts that-out.

Thanks for the details.  It seems like the "best" solution would be for Reallusion to provide an option someplace where all the roots for a custom "collected clip" would be set to a default which would automatically align with the roots of any existing  motion without the need to build up every motion at the origin with the translations zeroized.   Maybe just making all the roots visible and allowing them to be manually aligned (or snapped) would help. 

The "Align Actor Motion" and "Reset Motion Root" check boxes in the Motion Panel seem to have a mind of their own.  I've run into big problems when building complex motions and then going to an earlier section of the project to add something like a walk along a path.  The existing positions of the character later in time get moved all over the place.

Thanks again for the hints.

What tools are available for AML Script Editing?  The only reference I found on the Wiki is for an editor that works with iClone 3.

Thanks,

John
