Fustrating crash when texturing.


Recommended Posts

Hello, I'm massive 3Dcoat fan, what a fantastic program!

However recently (last 4-5 months) I've been having a persistent issue since the PRB update was released (possibly also linked with upgrading my GPU)

When texturing a high polygon model 300,000 (autouved) or even low poly model (manual uv)

When merging layers or preparing more than 2 / 3 layers at (2048x res) 3DC will persistently crash, Regardless of the time i have been using the program, sometimes hours some times minutes. (Save on every change is the only way I'm managing to get work finished)

Here's the version of 3DC im using (on steam, however its been patched as the steam versions not update AFAIK)

Here's the video card stats (Drivers were a fresh install (switched from ATI(AMD) to NVIDIA) albeit not the latest of the latest, Issue has been present however since the release of 4.5 and seems unrelated) (Note: video card is 2gb not 4gb, weird its showing that...)

I increased the VM pagefile thinking it could be that, However isn't being reflected consistently and made no diffrence.

And finally the error that is doing my head in...

Other notes that may be of help.

3DC is running of my main drive C: its not SSD and when i used the demo before purchasing 3DC i never had an issue running the program off a secondary drive (all drives are non SSD Sata.

Doesnt matter if i use 32bit or 64bit, openGL or Direct X, Cuda or Non Cuda the crash will always happen, sometimes if i save the file, restart 3DC and then merge visible layers it will not crash, but will crash again if i try to merge a new layer.

Using to high of a light count value when baking AO also results in the same crash, generally 1024 light count on openCL will crash, sometimes it will not when baking on CPU however the only way i can really bake an AO at this time is drop the value to 128, any higher increases the risk of a crash.

Working on the highpoly models uv and not even touching the texturing tools also produces the crash.

A fresh windows install isnt really ideal.

I have reinstalled 3DCoat a number of times, both using steam and the standalone installer, with no effect.

Any help would be appreciated,

Many thanks,

TK-

I believe you need more Ram as i had this issue as well.

 

From 8 giga took it to 32 and now my head cleared at least from this problem .

 

Also try to work with the non steam version (you can even if you bought it from steam).

How did you first upgrade the PBR version of 3DC when came out.

 

If you just installed over the pre-PBR build, then you will have errors and possible crashing. We use to be able to just install over builds but the PBR build change things to much. Now of course once we have the PBR version then we can just overwrite that one with PBR beta builds.

 

Also deleting the options.xml file in your 3DC coat folder not the install folder but the one under users might help...

 

The above two suggestions might not help but I did not see you discuss them in your post. Hope this helps some... 

 

I agree too more ram helps... I have 16 but will get 16 more gig soon. I would say 16 gigs is good as an average for 3DC. I worked using 3 gig at one time without crashing but I knew my limits...

Hello Chaps, Thank you for your replies.

More RAM would be ideal (and in time ill get more), I would totally agree this is the issue, if my laptop with 6gig of ram had this issue also, but it doesnt, whilst being slow it works without a hitch.
 

I have done fresh installs without steam, and I didn't upgrade an older version, Just uninstalled the beta demo (that worked fine) Once 4.5 came out these issues began. I never really had a crash with the 4.5 pre release beta / demo even with 4k textures.

 

Edit: Task manager also shows im not maxing out my ram or even getting close, 3DC can easily take up to 3-4 gig of ram and i still have plenty to spare.

Yes,  sometimes its our fault i must admit. 

 

If you want you can upload the model (if its not signed by NDA) and we will have a look

Its not under NDA but its also not my model so i would rather not upload it, either way it happens with low poly meshes also, so i dont think the poly count is the main issue here.

I know you do not want to uninstall but if all else fails, Uninstall, plus manually remove all 3DC folders under your user name, not talking about the Programs Files folder here.

 

Now no part of 3DC will be left on your system. You will lose all your settings of course and any alphas, created brushes etc... Many you can save though creating an extension under the file menu. You will have to re-register 3DC again. Again as you stated you did not want to uninstall, so only do if all else fails...

 

You might have done the above already.

 

EDIT: Not saying the above will work but it's a last resort as stated.

I have done, many times, but this issue is reducing my ability to work efficently so am looking for a faster solution.

 

You must be patience , Andrew is re working the code at a new base.

 

Trust me when i say that but all users using 3d coat at pro or even indie level we are waiting for this as it was the Holy Grail.....

I have re installed (by removing all files including the ones in my documents) doing a registry cleanup and a reboot, with no effect.

Issue seems to have started since the patch, so maybe ill avoid patching and see if that resolves the issue...

If you are using the latest Nvidea driver, you might consider switching to the previous one. I had crashes in 3DC and C4D with the October 7 build.

I'm running drivers from August, i dont keep the drivers up to date as these worked with the beta so saw no reason to update them.

Edit: So i did another full re install (outside of steam) , did a reg cleanup, unplugged my other HDMI monitor, didn't need to update 3DC this time as the installer seems to be the most up to date version and so far i can bake with opencl at 1024 and have had no crashes when merging 2k texture sheets.

The only difference I've noticed is my license now says educational, rather than consumer, kinda odd.

Thank you all for your comments and help!

What a great community to go with a great program.

Glad you got it working...  :drinks:

 

Send an e-mail to 3DC support to get the educational vs pro version license figured out so you are not limited to 7 paint layers in the paintroom and only 2 k textures plus no commercial usage.

I think I'm only on that license as i only paid 60£ for the license (via steam) so are locked to those limits. My modeling work is for game mods anyway, not commercial. :)
