Thank you very much, Mike!

I don't think there's a magic solution to this - it's probably very specific to the scene you're working on. You have to try to break it down to see where the problem lies. First, try giving all objects a standard default 3ds Max material and export like I suggested above. If it works, you can ...

Well, what about materials then? Are you using standard materials only? Does the export work if you apply a gray standard material to the entire scene?
There are some limits with CUDA:

It depends on hardware and CUDA.
Currently you can have up to 64 image textures, 32 float textures, and 4 HDRI ...

Did you remember to collapse the modifier stack for your objects?

Thank you very much for the pointers!
I clearly have a lot to learn here :)

I was trying to go for the studio look with my render - similar to the Mercedes, Audi or Lamborghini in the gallery. Even though I understand the importance of a proper background environment, these renders seem quite ...

Thanks

You're right - it does look small. I wonder why that is - maybe the DOF is too strong. I also used a lot of vignetting because I like that effect
Are there any useful ground rules to follow with car visualizations? Or do you just keep tweaking till it looks right?

With all the great car renders that have been posted, I thought I'd give it a try. This is not my own model - I think it's from Dosch Design. Getting the materials right is tricky so I definitely need to work on that in the future, but none the less, this is definitely the best car render I've ever ...

+1 for dongle!
Because I wouldn't ever connect a rendering machine to internet at all.


Well, I'm a little confused. Why would you need a machine dedicated to rendering with Octane? I thought one of the benefits was that we could add more graphics cards or use that expander thingy so we wouldn't ...

What a charming lady!

I was just playing around with some models and thought I'd share a couple of images. These aren't worthy of the gallery section, but I'm really impressed with the quality Octane is capable of and the ease of use :) The bar stools are low poly models, which were modelled by a friend of mine and ...
