Hi gyus
Recently I've been reading V-Ray documentation and many discussions here on forums about VrayDisplacementMod.
I understand the differences and advantages and disadvantages of 3D displacement with 'Edge leght" option turned on and off.
However I couldn't find answer for a question what is the use of 2D displacement. I tried to put together some idea reading the discussions and documantation but it's not clear for me.
Are there any scenarios where 2D displacement would be better than 3D, when it comes to quality, but what is most important for me - the used resources? ( mostly RAM usage, secondly render time )
The name of this mapping is 2D ( landscape ) and I've seen suggestions here that it's good to use for large flat surfaces like sea, or terrain, but why is it better? Actually if I set the smoothing groups on a model to the same one, I can render also 3D objects with 2D displacement, but will it give me any advantage in some situations?
I will be very thankful for your explanation.
