A couple years ago I tried out Vray RT but didn't have a lot of success as it had limited features and I assumed my old graphics card (GTX 580 3gb) wasn't up for the job. Today I finally updated to Vray 3.4 and thought I'd give RT another shot and I must say I'm amazed with the results. My crusty old GTX 580 is double the speed of my i7 3930k (6core CPU OC @ 4.1GHZ). My CPU is a few years old now but is still holds it's own against the new CPUs when it comes to bang for buck for rendering. Although the 3gb of GPU memory will be limiting in some scenes, these tests are making me rethink if I should update my entire system or just buy some new graphics cards. Latest gen GPUs CUDA core count is about 5x more than my card so I can only assume the render times could many times faster than my card. Some benchmarks are shown below.

More than a few people have been asking me how to export and use texture maps from Substance Painter in Vray, so here is a quick tutorial.
Before we start texturing, we need add in additional maps Vray uses. Glossiness, ior and Reflection. I'd recommend doing this before applying any materials as I have noticed that sometimes the additional maps can export as blank. If you already have a custom material then save it and reapply after setting up the additional map slots.
Apply your materials as you normally would. I purposely used two materials that will have different Glossiness, ior and Reflection values so we can clearly see some variation in the maps. A pure black or white map could be a result of the material having the same overall value OR step one wasn't setup correctly (blank maps)
Export the textures maps using the Vray preset.
In vray we just need to plug in the corresponding texture maps. Although I'm using Maya the standard Vray material attributes are the same in other programs like 3ds Max etc.
Here is the final result with zero tweaks. Just plug in the texture maps and render. Done!
I hope this helps anyone having issues using Substance Painter maps in Vray. If you have any questions then please ask :)
