I am running MAX2011/Vray1.5SP5
I am trying to achieve a corrugated cladding material on a project (see image ) and am testing two methods for this - with vray displacement modifier & with geometry. The former is better, as it saves modelling time.
Trouble with GI.
(See scene )
I added a vray displacement modifier to a plane using a gradient map (I also tried using an image) and I modelled the same thing with geometry.
Settings are very low to make the issue obvious.
As you can see (in this image ) there is a discrepancy between the two objects. The sheet on the top is generated with displacement and the sheet on the bottom is geometry. Why am I getting these GI errors on the displacement sheet? Shouldn’t the geometries be basically identical as far as GI calcs are concerned?
Does anyone have any suggestions on this?
