Losing it

[Per-Anders]

I've never had that happen, have you assigned objects to layers perhaps and hidden those layers? Or accidentally pressed the delete key? Or undone certain activities that has resulted in objects being removed? Have you accidentally turned off the visibility dots on objects or their parents? Have you set the object maanger root level to a higher level than the root? Another culprit apart form errant keys or clicks can be plugins, do you have any odd plugins installed?

[therealpepe1]

I'm using the solo plugin cannot rember who wrote it.
do you think it might be that

Thanks

YES!

If you hide somethigng with it--make ssure you unhide with it as well--you cant go back into the OM and un hide manualaly--it will start screwing things up.

[therealpepe1]

Oh well thanks for the replies, I guess that is the culprit.
I have hid an unhid manually in the object manager, but the objects just vanished they are not just hidden thats what confuses me. YES!

[JoelOtron]

Did you at any point activate the solo plugin?

If you have--then you cant unsolo/solo those objects manually--as the solo plugin has recorded the state of the object when you activated it. It could lead to "confusing" the plugin, so to speak. If you are not sure what you did--then maybe quit out of c4d,, remove the plugin and restart.

The only issue I have had with "disappearing" is if directly after working in materials or leaving a material selected... undos (not relating to materials) will make some materials disappear.. "redo" might make them come back or another material disappear. I mean the go BYE BYE permanantly... only way to get them back is revert to saved.

finaly someone menturing the disapearing polyobject problem

i have the same problem as wesware i think

somtimes when i hav a polymodel and a few hyoernurbs and some instances the



polyobject disapears out of the hypenurbs into nirvana (no going back helps data is lost !)
the polyobject teleports itself to the top of the hierachy
the polyobject teleports itself to the highest similar container (hypernurbs or instance)
it gotten better since 10.1 but still happens some time.
i cannot reproduce it so its very dificult to bughunt ...

[turner]

Wesware is correct. I'm finding similar problems here.


Pah!

Happened to me as well on several occasions. Reloading the vanished object(s) only result in something else gone, and so on.
Don´t have the solo plugin, so i can at least rule that out. Don´t know what´s causing the dissapearing though unfortunatly.
The only thing i can think of(and this is pure guessing), is that there´s some sort of limit of either objects or polys when dealing with large scenes, and that objects start to vanish when reaching that limit. Slightly odd though, since the "Out of memory"-message normally pop up way before that, and i´ve never had any on these scenes.

[JoelOtron]

This is really bizarre--have not heard of this before.
Im wondering, as PerAnders asked--are you guys maybe using layers?
Maybe somethinbg weird is happenning with objects tagged to a certain layer?

the other thing could be if you are using the OM filter-and forget--then turn off the filter. Any objects that have been filtered will still be the only ones visible in the OM until you go back to fitler mode and clear the field. There will be nothing in the OM to indicate why the objects are missing--Ive done this myself on occasion.

Sounds more like a weird bug however. If this is a real bug...
this is scarier than a good horror film.

[mogh]

yeah this is scary ... i had to take a nightshift back then beacuse a modell disapeared an i didn notice it and saved the only file i had without the object .... bang there were 5 hours of modeling gone ....


no it happens in my case when i do normal boxmodeling stuff ... with hypernurbs and instances ... cant rule out that this is exclusive but ever since it happens i had these two types in the object list.

saving and reopening the file sometimes helpes, opening on another pc isn't reproduceable but it happened on all my machines ocasionly

like a said a "b$$$$" bug to track, cant even imagine what maxon to write because its so random ....

perhaps when we all contribute we can narrow it down ...

Important: the "bug" occurs when i hit undo ! (moved points etc.)
cya

[Rochr]

Never use layers, so that can´t be it for me.
And i can rule out both hitting delete and/or hitting the visibility dots.

The problem with "reloading object, loose some other object" ends when restarting cinema, and fortunatly it´s a rare problem, but nevertheless annoying when it does occur.

[therealpepe1]

Guys this is amazing I thought I was going nuts. I have also experienced some of other problems mentioned above. One that freaks me out is that sometimes I move an object and it creates a copy in the viewport but not in the manager or if I copy in the object manager I get double copies.

[Srek]

@ those who experience vanishing objects and changes in hierarchy that do not use any plugins:
Have the scenes in question been created inside of CINEMA 4D or were they imported from a different application?
If they were not created inside of CINEMA 4D, which application has been used and how was the scene imported?

Thanks for any help on this in advance

Cheers

[mogh]

Standart Cinema from sratch .. nothing fancy - happens when i'm modelling old school box modeling ... point alignment and so on. seems to be linked to the undo function in my case

never had problems in that way with importet files as far as i can remember.

pehaps i make a screencapture when i start to model for prizefight2 I have it in my guds it will apear then ..

[Rochr]

I don´t know if i´m to any help considering i´m using 8.5, but this seem to be a common error for several versions so... In my case i use Cinema only with no imports. I have a few plugs installed (Fizz, Easyclone & Makethicker), but that´s it.

[wesware]

Srek,

Native Cinema Scenes...
I have lost lights and materials... no poly objects yet.
Only happens when I am "un-doing", "re-do" might make even more disappear.

Could be a plug issue, materials in layers.... not sure.
I use Chamfermaker and Deform-fit, that's it for R10

[robotbob]

i have had this once from a file sent from another c4d user - the joints were missing - i copied and pasted into a new scene and the items showed up.

I posted this problem a few months ago and posted a test scene, no one else seemed to have the same problem at that time. Maxon UK stated that no one else had reported it. I am glad to see I was not imagining the problem. It is definately related to undo and redo but is completely ramdom and intermitant. I have done a clean install and things have improved, and 10.1 has improved things again for me. So I suggest you install cinema again and see if things improve.

[Srek]

So far this behaviour has not been reproducable here at MAXON. If anyone can provide me with a scene and a descritpion on how to reproduce this in R10 i would be very thankfull.

I think the problem is specific to each install, all the problem files I have had have been fine on other computers. So sending a scene file would not help, you would have to analyse the actual install on individual computers. It can not be a global bug or everybody would be complaining.

[Srek]

I think the problem is specific to each install, all the problem files I have had have been fine on other computers.
In that case i'm pretty sure the error is not with CINEMA 4D itself but with faulty installations.
Only when it comes to input and output of scenes or parts CINEMA is dependent on stuff outside of CINEMA 4D so a changes in the environment do not change CINEMAs behaviour during modelling etc. .
Without beeing able to reproduce a problem (either by example or by chance), we are simply not able to fix it.

I added the save incremental command next to the save icon in my layout and I use it quite often. At least on an hourly basis.
If you don't like changeing your layout I suggest you add a shortcut to that command
(alt+shift+s shoud be free).
Cinema has built in technologies to minimize data loss, you just need to use them.

Regarding the subject, I never experienced such a wierd thing like loss of obect or materials.
I'm heavily using layers and have a bunch of plugins installed.
Any chance that this is an OS depending issue?
I'm on a PC with WinXP SP1.

That is fair enough and is why I suggested that people having these problems should re-install. I am not getting any of these problems now only a very occasional crash (3 times in total since 10.1) and the recovered file is fine when opened.

[noseman]

Is it possible that the objects don't dissapear, but move to another location in the scene?
I think I had a similar problem VERY long ago (I can't remember any specifics), and the objects where moving, not dissapearing.
Next time this occurs, try selecting the "missing" object in the OM and framing selected (s key).

Just in case, make sure there is no animation in your scene. Any undo - redo functions, trigger a refresh and animated objects may return to the previous keyframe position.
Also be carefull with the "Transfer" tool, don't select it by mistake. Finaly, always consider OGL card refresh problems. Give C4D time or (for troubleshooting purposes) use SW shading.

Hope this helps.

[marshalartist]

The objects dissapear from the object manager as well as if they were deleted!

[Srek]

Is it possible that the objects don't dissapear, but move to another location in the scene?
This problem has been observed on very few occasions with scenes imported via plugins.

Don´t know about anyone else, but the times it has happened, i´ve gone through every object in the scene and they were simply gone.
For me personally , it´s no big deal. Ok, annoying when it happens, but it´s still so rare i don´t consider it a problem. And after a restart, it works just fine again.

As for reproducing it, i couldn´t do it if i wanted to, but every time this has occured, it has been in really heavy scenes, with a few million polys and thousands of objects.

[mogh]

So i installed camtasia trial and opened an project where it happenend to me, i couldn't get the diaspearing polyobject bug but after 15 minutes the "similar" polyobject "jumpingbug" in hirachie acurred and i have it on tape and file


here is the tape.
http://www.defcon-x.de/mogh_forum_files/jumping_bug.avi


and here the file, please do the same action as i did to see if its reproduceable
i took the loop cut und undid the loop cut nothing more
http://www.defcon-x.de/mogh_forum_files/shoe_jumping_bug.zip

lets see
cya

[marshalartist]

Yes that is what used to happen to my scene files in the first version of R10

[Srek]

Thank you Jan for the scene, fortunately this occurs here too so i'm able to report this to our programmers.
