Hi,
I recently migrated to Blender with Octane from C4d with Octane.
The following pic is a render I produced in C4D with Octane, compositing the Bumblebee model into the live action shot of my driveway.
I tried to match the same render in Blender, using the exact same HDRI lighting and exact same materials in the model (Octane Universal materials...I copied the settings for each material over from C4D).
Ignoring the color difference (due to differences in color management), the HDRI reflections are much more dull and less sharp in the Blender render. This is despite the model and HDRI being placed in almosthe exact same spot, and the HDRI settings being the same.
Any idea why this is the case?
