Maya 2d/3d Texture Nodes - Visual and render time differences 3.1 vs 3.3
I use V-Ray primarily for product imagery and several of my shaders use Maya's procedural 2d and 3d texture nodes to mimic specific beadblast, brushing, mold-tech, etc. type of materials. Since upgrading to V-Ray 3.3 I noticed an increase in render time along with stark visual differences from V-Ray 3.1.
Attached is an example of a simple VRayMtl using a granite 3d texture node in the bump and reflection color channels. Render global settings were left unchanged.
Intel Xeon 2.5GHz (2)
128 GB RAM
Quadro K6000
Maya 2015 SP6
Original image size - 5k square
Render Time:
V-Ray 3.1 - 1hr 18min
V-Ray 3.3 - 1hr 57min
I should also note that render times vary significantly based on the amount of available RAM. On a render farm blade with the same processors but only 64GB RAM the render time increased to 6hr 34min in V-Ray 3.3.
The visual differences occur on several other materials as well that use Maya's texture nodes. Any insight as to what changed between the two versions that could be causing this? Hopefully it is a simple setting as I'd prefer not to have to update my entire shader library for 3.3.
