Ya now after updating iclone to 7.2.1 whenever I am rendering a video Windows 10 is giving a BSOD with error critical process stopped. When I restart, windows will go into repair mode and unless I go into command prompt using window recovery and fix the boot sector, it will not restart.
I am rendering again to check whether it is iclone or something else but happened twice now with the new update.

and happened thrice now. I made sure internet was off and other processes were off too.
How do I roll back to the old version till the bug is fixed?

Personally I would take a look at my video drivers. Especially if it only happens when rendering.

seems like I have the latest AMD GPU drivers installed. This was not a problem before the iclone update and games like LOL and others are working fine.
|
|
By Famekrafts - 7 Years Ago
|
I have uninstalled and reinstalled AMD drivers, even recorded using AMD relive and everything works fine.
This time the complete rendering got over and then iclone crashed. No BSOD just black screen and it corrupts the boot sector somehow.
Can anyone tell me how to re roll to the previous version or reinstall iclone without losing all the custom props, motions and avatars I have added?

that's usually caused by a buffer underrun - meaning ...that something is not processing info as fast as iclone is giving out info.
so for instance, if the drive is asleep and you are trying to render, the buffers get full...but no place to print ...iclone doesn't stop to wait ...it keeps filling the buffer till crash... OR if you have a bad drvier somewhere and it's clogging up the data stream ...it will crash...it can be a variety of things .....basically whats happening is iclone is sneezing a burst of data stream, and your computer is pinching it's nose -eyes bulge- ....Crash!

Ok just for testing I used custom motion on slacker morph and it rendered without any problems. so something in my scene is causing the crash.
I have already rendered a lot of animation from the same scene, the only difference is I just bought this toon frog from iclone store and animated it. It looks outdated because motion puppet isn't there and edit motion layer doesn't open the normal interface but old bones one.

Could this be causing a crash? If so how do I fix it?

If that is the case how do I increase the buffer stream? I still believe it is either the frog or a spotlight I have placed in the scene. I am removing the spotlight and re-rendering again.
Basically, the timing of the iclone update matches the toon frog I bought that is why the whole confusion.

it's not a matter of speeding up the data stream, technically that's regulated by the chipset and cpu on your motherboard ....it's more of a case of finding out where the data stream is being interrupted or not keeping up with iclone's data burst when rendering.
that could be your codec, or your intel driver set, or your video driver, or 3rd party software that's interrupting the stream - ie - video capture software, malfunctioning anti virus, even an overheating or slow video card can do that ........it's hard to say because so many things can interfere....but if you follow a troubleshooting path in that direction - it may help you identify the cause.
Do things like run a direct x test, look at your system performance for spikes and drops in data - peek at what software was most active in the task manager when iclone crashed....etc ...stuff like that.

It was the dumb spotlight I added to the scene with some high values, which was causing the crash. Also, I changed the default video player from windows player to vlc (for opening the video after export). Now the crash is not happening, wasted many hours on this silly mistake. :)
Thanks, everyone.

If you have a repeatable "I can make it crash" situation, please report it on Feedback Tracker, and include access to a copy of the project if possible.
You can also provide "instruction" here and see if anyone else can duplicate the crash.
Often times, duplicating a bug is 80% of getting it fixed.

Ok guys it is still happening, I have even increased the virtual memory of all my drives but it is still crashing the computer, exactly when I render the video of my scene.
Going to upload crash dump files to the feedback tracker.
This is really frustrating because when I render an animation of my character without all the dof and gi settings and my scene it never crashes.
So something in my scene is causing it and I have no idea exactly what.

There is a "Preview" render and a "Final Render". The final one has super sampling which may be causing the crash. If you select 3*3 SS, your tripling your VRAM needs, I believe.
Many of us have discovered we really get a very nice render using the preview mode. It's faster too! :)
Remember you can always do SS if you need it by rendering at 4K and resizing to HD in a video editor.

Yes I am doing final renders and using 3 x 3 ss.
How do I calculate how much VRAM my scene will require using 3 X 3 ss or 2 x 2 ss?
I have a 8GB AMD graphic card, I think that might suffice isn't it?
The issue is that before the update I rendered using 3 x3 ss same scene with different animations and there was no crash.
I will try with 2 x 2 ss and see how it goes.
edit : iclone while rendering should also show how much VRAM is being used just like while previewing using timeline. This will really help and they should add this feature.
When I am running the animation in timeline it is using almost 3.2 GB VRAM, so using 3 x 3 might be causing the crash going over 9 GB, I am trying to render at 2 x2 now.
Plus I am running dual monitors and others apps open in the second window.
While rendering in Blender we can always combine 2 or more graphic cards to increase total rendering speed.
Does iclone also render faster if we combine 2 x 8GB graphic card on the same CPU?

Well, it crashed the PC again, the only difference is it reached 228 frames out of 270 frames this time.
I think VRAM is the problem as you mentioned.
Does Iclone while rendering loads in VRAM only part of the scene of the viewport which is visible or it stores in memory all the assets in the scene?
If I make the objects out of camera view invisible during rendering process will it release some VRAM?
|
|
By Rampa - 7 Years Ago
|
With the 7.21 update, it is supposed to be releasing the memory when you hide stuff. Give it a shot!
The VRAM may be it, but it does use system ram if it overflows the VRAM, at least in the preview window. Do try rendering in preview mode instead. I doubt you'll see any difference visually, but performance may improve.
Multiple cards in SLI or Crossfire may actually cause problems. It is made for a single card.

If it is Vram thats causing an issue there must be a bug. I've rendered animations in iClone 7(not 7.2) that used in excess of 15gb and my card is only a gtx 970 with 4gb of ram. The system should use system ram when vram is full.
|
|
By Famekrafts - 7 Years Ago
|
Well I tried again this time I opened Windows task manager to see how GPU is being used.
GPU usage never went above 4.5 GB out of 8GB and cpu never over 20 %.
So I doubt VRAM is a problem here.
Something is wrong with iclone itself. Any idea how can I re-roll to the old version of iclone?

yes that is the catch because with virtual memory it is showing I have 20GB of VRAM while the GPU usage is not going over 4.5 GB

The only way to roll back to an earlier iClone version is to uninstall 7.21 and reinstall the earlier one that you want to use. Since only the latest versions are available for download from a user account you will have to revert to using the last installer that you downloaded and saved.
Also be aware that in almost all cases Projects saved in a later version can not be opened in an earlier version. Reallusion iClone files are not backward compatible.

That means I will also lose all the custom props and motions I have created in this version?

Just to add to the problem. You will also need to roll back 3DXchange to the last version. Character Creator should be OK due to the fact that there was no update released along with the iClone 7.21 version.

Sorry if this was covered before (I just woke up and I'm not *quite* awake) but have you tried rendering to images instead? (Which you really should be doing anyway -- the only reason to render to a codec is for test purposes -- no final render should ever be done to a codec in iClone).
My hunch is it will work just fine, but it would be interesting to know.

One more issue happening is that after booting up the system, iclone crashes the first time it starts. It doesn't happen the second time.

I have just rendered the same avatar animation without the scene as image sequence of dancing and it rendered without any problem for over 600 frames.
So there is some issue with my scene itself, even though it is not using over 4.5GB of VRAM while rendering.
I am uploading screenshots of iclone visual settings, could any of these be causing the crash, because I am new to iclone, I might be overextending few settings.

What's in the scene? Are you using any PopVideo?
You may just have to start deleting things until you find something that it just doesn't like.

It's not the scene -- it renders just fine for me (I can't render it with the avatar since I don't own it).
So it's your computer somewhere.

You might also run diskcheck utilities -- something smelled fishy to me in the first place when you said the render corrupted your boot drive. That really can't happen -- nothing iClone could do would ever do that. However, if a disk has issues and iClone is trying to write to some bad sectors that might be an issue.
It could be as simple as you need a new boot drive (if it's older than a year or two that's the likely possibility -- disk drives will ALWAYS fail, it's only a matter of time).

Nope after 2 and a half hour of disk check and repairing it is still crashing.
I noticed something odd - Iclone is capped at 4.5 G of VRAM. It is using .2 GB of virtual memory instead of using additional vram from the GPU.
Maybe that is why the system is crashing and giving memory error, the first app to crash is the real illusion hub app. This time the rendering finished but once I closed iclone, every other app crashed giving memory error c0000000e and on restart, it went to recovery again.
How do I make sure that Iclone can use at least 7GB of VRAM instead of just 4.5GB?
|
|
By Famekrafts - 7 Years Ago

I am rendering a very heavy scene in blender which is installed in the same drive and saving in the same folder and there are no crashes.
I believe the problem is with iclone in some way. Maybe the VRAM capping at 4.5 GB is the problem.
I am going to disable GI thus reduce VRAM and then try to render.
|
|
By wires - 7 Years Ago
|
|
You mention that only 4.5 GB of VRAM is showing as being in use by iClone. Perhaps there is something not in order with your GPU RAM.
|
|
By Famekrafts - 7 Years Ago

I disabled GI and it started using 5GB RAM from the GPU.
I have tried everything - defragged my drives, did scan disk checks for bad sectors which took hours, optimized my drives, used anti-virus and now even removed many props to reduce the VRAM use, which has come down to 4 GB now. But once it reaches 100-120 frames of animation ( this is a new scene) it starts crashing every other app in the background. If I do not click any button iclone keeps rendering till I close it at the end and then nothing works. Have to press the reset button and goes into recovery mode to fix boot sector.
I can complete animating the scenes just rendering is the problem.
Also updated to latest AMD drivers released today. Nothing works.
If GPU was the problem Blender would have crashed too while rendering but it works fine, just takes hours to render few frames.

Hi Famecrafts,
I tried the project and found no problems with it in iClone 7.21. I was able to load and render the project to various HD resolutions with GI and DOF turned on. Because of this it would seem you have a local system issue, most likely graphic card related if the crash happens when rendering.
I would advise adding your dxdiag.txt and crash dump to your Feedback Tracker report as it will be needed by the dev team. You can also send the information to our Technical Support department if you wish using the link below.

Looks like some gpu or drive problem. Going to open my computer and clean and reconnect everything again.

Nope. removed and re installed ram, hard disks and GPU. Ram still not reading 24 gb only 16 gb.
Used the amd utility to remove all traces of graphic card drivers, deleted all the files manually from the drive and then re installed. Then defragged all the drives.
Now it is working great. rendered over 900 frames just now.
