i can't even find a single bug.. great release Karba!!!

the only missing future is Light Cache (pre calculated indirect lighting)... who knows when octane team will implement it.... i hope one day....

Please, can someone explain to me:

- What is Coherent mode? What does it do?
- What is Path Termination option and what does the power value do?.

This is what they said:
"We also implemented a new path termination strategy, which is a bit tricky to explain: In the past the there was this ominous pin "RR probability" which in most cases only worked good when set to 0. With the new algorithm we try to provide a system where you can tweak render speed vs. convergence (how fast noise vanishes). Increasing the value, will cause he kernels to keep paths shorter and spend less time on dark areas (which means they stay noisy longer) but may increase samples/second a lot. Reducing the value will cause kernels trace longer paths in average and spend more time on dark areas. The current default of 0.3 works good in most scenes, but play with it. For example, in two interior test scenes it actually payed off to set the value to 0.5 - 0.6 which increases the samples/second a lot and then just to render more samples.
The direct lighting and path tracing kernels also have a new option "Coherent mode", which increases the render speed, but causes some "flickering" during the first samples/pixel and should be mainly used for the final rendering and if only if you plan to render 500 samples/pixel or more."

soon i will upload a video i made with this version and the noise doesn't seem to be static at all...

it is strange i had this too sometimes it was static but when i render now it is not

Noise pattern is static. I showed it to you.
The strength of it depends on so many variables (textures, rendering time..etc).
Also don't confuse it with caustics or specularity flickering.
Just make a simple test scene like i did and see yourself.

Ps. Your video is too compressed to tell anything about noise.

Hi Karba, there IS ONE BIG problem i think....
- sometimes rendering freezes suddenly and randomly when i render multiple frames for an animation!
It stops and the viewport becomes white.. i have no videocard issues. The GPU temperature is good - MAXIMUM 70°C at 100% load.
PSU is OK and i have already made dozens of stress tests for the gpu and system in general... it simply cannot be the GPU or system issue.

I have a scene where it happens quite frequently! where can i upload it? in order you can have a look

what is your gpu config?

just send it to me if it is not too big
[email protected]

or use google drive. I can't suggest anything in this area.

GPU config:




the scene is quite big, maybe 60 mb zipped. i will put all the textures in another folder because they do a lot of displacement so are essential for my scene. CAn i upload it on
file hoster ? and send the link via email?

p.s. i think the bug occures with scenes that have a lot of turbosmooth option marked only for rendering (not in the viewport)...
