Controller disappears from scene time track

<< < (4/5) > >>

AlecJames:
This is not a big issue for me, once I know where it is.

AlecJames:
Hi Steve, I have some corrupt project file issues with 1391, I haven’t tested older versions.

They are caused by renaming bones in figures when the figure is used in a scene.  There are some variations.
1) The an8 project file is truncated part way through making it unloadable
2) The an8 project is empty after saving
3) Renamed bone is duplicated
4) Key lost, (found during testing, probably not a real-world scenario)

#1
Original issue, I can’t recreate, this is the symptom I’ve seen twice in my project (events are many days apart).  I try to open the project and anim8or says the file can’t be loaded.  In the text editor I see that the file is truncated.  The truncation point appears random.  My project is much more complex than the tests I describe below where I’m trying to recreate in a simple example.

(Tip for anyone that has no internet usage restriction - I save my projects to MS one drive which syncs them to cloud storage.  If I lose the project, I can view the project file online by right clicking and selecting ‘view online’, view the ‘version history’, click on any saved version ‘…’ and select ‘restore’.  I also take snapshot copies of my project files - I may have several anim8or projects for 1 top level project.)

#2 The an8 project is empty after saving
New project, create a figure with 2 bones, both in menu folder “testfolder”
Add the figure to scene
Set “expression on” for bone1-x (leave the default script, I double clicked the controller in the time track window)
Save as test.an8, exit

Open and load test.an8
Rename bone1 in the figure to zz1
switch to the scene and play
Save
Anim8or crashes, (the project file is now empty)

----------------------------------------------------------------------------------------

#3 Renamed bone is duplicated
New file, create a figure with 2 bones (no folders)
Add the figure to scene
Add a key on bone1-y frame 0 (double click the time track, add key value=0)
Go back to the figure and rename bone1 (to zz1)
Save as test.an8, exit

Open and load test.an8
In the scene the bone1-y controller still exists with its key; zz1 as added with new xyz controllers

-------------------------------------------------------------------------------
#4 Key lost, found during testing, probably not a real-world scenario
New file, create a figure with 2 bones
Add the figure to scene
Add a key on bone1-x frame 0 by double clicking the time track and using add key 0
Add a key on bone2-x frame 30 by double clicking the time track and using add key 0
Save as test.an8, exit

Open and load test.an8
bone2 key at frame 30 is missing


Hope it's useful; thanks for your help :)

Hi Steve – sorry another issue, this is probably causing me most issues at the moment and I mistook the cause to be the above –

New project
Create a figure with 4 bones
Add the figure to a scene
In the scene time track, double click z controller, set expression on, for all 4 bones Z joint (default script is fine)
save the file to test.an8
exit

Open and load test.an8
All is well…
Double click bone1-x controller in the time track frame 0 add key value =0
save test.an8
exit

Open and load test.an8
In scene mode all the expression on settings are lost


I’ve redone my animation loads of times and keep losing it, now I know why :) (on the plus side it gets a bit better each time ;D )

I didn’t understand what you meant by rotate bone mode.  Instead of double clicking in the time track, in scene mode click rotate bone, then double click the bone with the middle mouse button (to get the Z controller key dialog)?
I repeated the above using rotate bone / middle mouse button = same problem (1391)

I’ll see if I can find a work around – did I understand “rotate bone mode” correctly?

Thanks A

Steve:
I'm looking at these now. There hasn't been much use of scripted joint angles in the past so, unfortunately, there seem to be a lot of issues.

AlecJames:
Thanks :)
