Hi all! I really hope someone here can help me. I am currently working on an interior scene and getting long render times to achieve a noiseless image. I am rendering via pathtracing kernel at 16000 samples with a max depth of 5 at 1024x663 resolution and still not achieving a completely noiseless image by the time 16000 samples are calculated. As you can see I am getting a completely visible image but the noise just doesn't want to clear up. Render times are taking roughly 40 minutes for one frame. I have the latest GTX 580 drivers installed as well as Cuda 5.

As for the lighting, I am using a texture environment with an RGB value(importance sampling on) for natural light and blackbody emitters for all the artificial lights in the scene. As for the ceiling lights, I am wondering if or if not Octane lights are a bit more optimized than blackbody emitters in Octane for 3dsmax. I am looking to do an animation for this and current render times are gonna make this impossible, so if anyone can shed some light on how I can get down my render times via pathtracing I would greatly appreciate it. I've seen octane interior animations people have done with the same GPUs via pathtracing with claims of much shorter render times and higher resolutions. Specs to my workstation are listed below. Thanks!

Hi

Try to set caustic blur to 1.0

Hi Karba thank you so much for your reply. I turned the caustic blur to 1.0 as you said and unfortunately I'm still getting the same slow result. Any other suggestions for me?

Please show you picture after 1000 samples/pix

Here's the render at 1000 samples as requested with caustic blur set to 1.0.

In this case probably you need to place portals in windows.

Already tried Portals in the windows it seemed as if it actually bumped up the render time by 5 or 6 minutes. Is it possible I may be missing some drivers that are making things not run properly? SLI is disabled and as mentioned abovbe i have the latest NVIDIA drivers and Cuda.

I don't think it is a driver issue.
What is the wall material?

Wall Material is nothing but a white diffuse material. I honestly don't understand. Could it be too many Blackbody emitters?

Try to set wall color to 0.7 0.7 0.7 instead of 1.0 1.0 1.0
