I'm having KeyShot crash a lot when trying to render to TIFF. It happens only to certain files, and I am trying to locate what triggers this. This is obviously a huge disruption of my workflow when certain models are impossible to render out to TIFF with Alpha channel.
Anyone else have this happen to them?
Most likely you are running out of memory. What is your system setup?
I'm on a 2011 MacBook Pro 2,2 GHz i7 with 8 GB RAM.
Also, we are not talking very complex models here. Just a handful of parts.
What renders to TIFF and what crashes seems quite random. I'm still trying to figure out if there are any significant differences.
One thing could be that you have an issues with write permissions. If KeyShot can't write the image into the target folder, it may crash.
I also get this "out of memory - expect crash" when rendering some files. Appears totally at random. I think the bug has increased in frequency since updating to version 2.3
You are running out of memory - this is not a bug. How much memory do you have, how big are your files, and how big are your renderings?
I also guessed it is due to lack of memory, but neither the files nor the rendering resolution are very large. I have run ques of more complex jobs before, but for the last couple of weeks this crash has been more and more frequent. Maybe it is because of the update to 2.3?
Nothing changed with 2.3, except a few importers. If can share the file, we can take a look. Send to support@luxion.com, please.
Sorry, but I can't share the file. I will try and change some settings though
What are your settings, and what kind of materials are you rendering?
Take a look. Maybe I just need some new hardware
Hi lillusaur,
New hardware wouldn't hurt.. :-X You may have 8 Gig of RAM installed but you must be running a 32 bit system as it's only recognizing 3.2 Gig. That being said, you shouldn't be running out of RAM though, but you might. You may want to keep an eye on it while rendering just to make sure that isn't the issue. The only other thing is that where you are saving these TIFs may be write protected; maybe do a quick test and have KeyShot save them to your desktop.

yes, I'm stuck on a 32-bit system sadly. :(
I'll check the write protection-thing.
BTW when the file crashes, the RAM-count in the render window is usually around 1.3 GB
Can you output to exr instead? The memory usage for exr does not increase when you render a high resolution image.
cool. I'll try EXR
I have also had system crash problems with high res outputs. I have sent files to support previously and was told variously to "use real time rendering" which does not give the same quality image, and most recently told to "save to EXR" because is does not fill system memory (16 gigs available). This past weekend the bug has raised its ugly head again and saving EXR did NOT keep the systme memory from filling and hanging the system. I am a long time user of cad software and am accustomed to getting better response from support and by this I mean more than just getting the automated we have recived your iput and your ticket number is xxx and the status is "open"
My system is about to crash as I write, so
Continued from my previous reply, attached (hopefully) is a crach snapshot fyi.
Guys, I am having the same issue. Keyshot 2.3 as well as Keysot 3 both crash as soon as I hit the render button. I am trying to render large 300 DPI 12k by 12k pixel images for the purposes of a billboard ad. I have tried rendering Tiff files as well as EXRs. Both crash. I can render my scene at smaller resolutions just fine, (under 9k by 9k). I have successfully rendered images larger than 12k by 12k but for some reason it wont render the scene I want without crashing. :'(
I'm gonna keep working at this problem. I will share some answers if I find anything useful.
Are you running the 64bit version of KeyShot? The 32 bit version has some strict limitations on memory usage. Have you had a chance to try KeyShot 3 yet?
I got the same issue " out of memory" after upgraded to keyshot2, even keyshot3 demo. I also tested on high performance (32bit and 64bit) PC, it has the same problems. One thing confused me, I test the same CAD file on the old hypershot and keyshot 1.9 version, It was very quick, and no problem at all. Does anyone know the answer?
