Hi,
I got a incorrect rending when I tried to scale my object bigger
(because I need to get correct scale of the scene)

I have tried to use different plugin version in houdini(16.5&17) and getting the same result

Hi,

In the kernel nodes, or in the render target HDA kernel tab you have a "Ray Epsilon" parameter that should help with these kinds of issues. Be aware that Octane works with single precision floating maths, so if the scene is too big or too small, tunning this parameter could be needed to remove the rendering artifacts.

Hope it helps,
