Yes, it is iRay. Render times vary depending on how much I have in the scene. For me, it can take as little as 45 Mins to about 8 hours. Keep in mind I came from a 128 MB video card to a 1.4 GB nvidia GFORCE GT730 and a Pentium i7-6700 and 16 GB ram (Before, it could take day,almost a week) to render a single image)Some times I could only get 3-4 characters at a time. (The call to arms image I did took about 2 days at a time with 3 characters at a time at 22 characters + post work to bring them all together) So 45-Mins to 8 hours is a God Send for me.
Also keep in mind,if you go way of iRay, 3Delight shaders and ambiance do play well with iray. I have had to reshade most of any surface to iray for a more realistic look.
I say give it a go.I love the results I get out of iRay
Quick question, Is this Iray and if so what was the render time? There's so much Iray support that I'm thinking of breaking into it but when I use it the render times are ghastly.
