Hi Spills, I've copy/paste from other discussion:

OctaneRender® 1.025 b2.57 Test release [CURRENT]
Hello,

The OctaneRender® Team is pleased to announce the beta 2.57 Test release.

Changes introduced in 2.57

Deep channel rendering.

Octane has a new kernel which renders false-color images of the scene, containing various types of
information about the scene. The following settings are available:
Geometric normals
Shading normals
Position
Z-depth
Material ID

For display these values are scaled to get values approximately between 0 and 1. All tone mapping
settings except for gamma and min_display_samples are ignored. For the Z-depth setting the exposure
setting controls which value is mapped to white. To save these channels you should use untonemapped
EXR. And in scenes where the environment is visible you should enable the alpha channel.


I Hope that help u.
