When I go to render a scene and the active pathtracing the picture is full of noise, and these noises do not always gone as I solve this? has increased the higher light does not work, continued noise in the image, what I do to eliminate these noises of the image?

Strong noise could exists be because of:

1. Bright spots in HDRI - Solution: play with gamma or blur the HDRI
2. Extremely powerful lightsources - Solution: lower power
3. tiny lightsources - Solution: try to make them bigger if possible
4. Short rendertime - Solution: Cook the render longer

There's also a noise removal feature that automatically removes usually around 99% of noise (from my experience), but should only be applied once a render has cooked for a while. Otherwise the image looks blurry.

I'm new to Octane - where is the noise removal feature?

Thanks!

Hi,

You should render your final images with the 'PMC' kernel, not the 'pathtracing' kernel,
and give it enough time. Also, purchasing a high-end gaming GPU like a GTX560-70-80 will make octane run as it's meant to run.

An alternative is using the 'directlighting' kernel with the indirect lighting changed from 'ambient occlusion' to 'diffuse'.
This will give a slightly less realistic image, but much faster render times with less noise.
