Keep getting failed renders, need help urgently.

Cloud Cloud Rendering Issues

Hi I have to deliver some renders to a customer, but i keep getting errors.
These renders are 4k by 4k pixels, they were rendering well, until my client asked me to have a layer of a glass material over every object, I am having success rendering if i change the resolution to 500 by 500 px.
these are the logs of my attempts :

renderer exited with code 139

All of the attempts had the same log, i am not really sure whats doing this, i also tried to look up code 139 to see what it was but cant really find the documentation.

Please any help is appreciated, as i need to deliver these renders in the next 2 days.

Hi @simo_silva ,

I’m sorry for the issue! Can you please send us a sample scene which reproduces the problem? Currently the information for the crash that we can read from the log is too general and the scene will help us see it in more detail. I’ll make sure that we answer you quickly enough.

Thanks,
Vladie

Hi @vladie thank you for taking the time to help me out!

you mean the 3ds max project ? i can send it , is there a way to send it privately ?

Hi @simo_silva ,

Sorry that I didn’t mention this. Yes, please share with me the 3ds Max project with the assets. You can send me the link in a Direct Message here in the forum.

Thanks,
Vladie

I have sent it hopefully you can find out whats wrong!

Hi @simo_silva

Most probably the issue you have is related to displacement. You need to optimize it to fit the scene file into the memory.
If you use displacement in materials directly you can optimize it from here. Please increase the edge length parameter to reduce the geometry generated by displacement and save memory when increasing the resolution.
You can find out more here in our docs.
If you use the VRayDisplacement mod you can optimize the displacement from here.

Thank you! unfortunatly i had to go using bump maps only due to time constraints, but will experiment with that solution!
