Plug In Precision of Values are limited to 6 digits (0.000000) whereas Standalone has 7 digits (0.0000000).
After entering a Value only 3 digits (0.000) out of 6 are displayed and clipped (when selecting value 6 digits are shown again).

Hi,

This will be a good thing to look into further. From initial exploration, it appears that this is a Blender limitation. Internally, Blender keeps to a 7 digit float precision, but can (rather inconsistently from what I see) round the display values - thus giving an impression of less precision than there really is.

Depending on how crippling this is to standard Blender workflow for Octane users, we could perhaps investigate for a future release.

Cheers,
Azen

Hi Azen,

thanks for looking into it.

It seems indeed that there is a bug in Blender 2.79.
Blender 2.78 does display all relevant digits.
