hello people, this is my image with the estimated time of 48 hours to render, how do I reduce this time?
I'm using Octane in 3ds max, the file is 90 mb, my pc: Intel Core i7 3.40, Nvidia GTX 660 ti, 8gb of memory RAM
Octane settings are:

1.) Why V1.2 ?
2.) Switch to PT
3.) Maxdepth way too high. Try 10-16
4.) Samples for light ->10000
5.) Get a better GPU

I guess the problem is the maxdepth 64... In the octane manual they state that light pretty much never bounce more than 16 times...

Maximum Depth (Max Depth)
The maximum number of times a ray can bounce/reflect/refract in a surface. Higher amounts mean also higher render time but more realistic results. For outdoor renders a good setting is around 4 maxdepth. For lighting interior with natural light (the sun and the sky) you will need higher settings such as 8 or higher to allow enough light to bounce around in the scene. While high values are possible, in reality rays will not usually go beyond 16 ray depth.

I use maxdepth of 4 for exterior and 8-12 for interiors.
