mental ray iray Maxwell support in 3ds Max 2015 SP2

Maxwell GPUs

Maxwell is NVIDIA’s next-generation GPU architecture for CUDA compute applications.

Please check the current list of Maxwell GPUs.

In order for iray to render on Maxwell GPU you need to patch the iray library which is distributed with 3ds Max 2015 SP2.

Without this patch, iray in 3ds Max 2015 SP2 will render using CPU only, if you have a Maxwell GPU.

Step by Step Procedure

Backup iray Library

iray library is typically located under:

C:\Program Files\Autodesk\3ds Max 2015\libiray.dll

The version which ships with 3ds Max SP2 is 3.12.1.17:

3.12.1.17

Rename or move your original iray library in case you want to revert back to it.

Update iray Library

Download iray library version 3.12.1.18 and place it under:

C:\Program Files\Autodesk\3ds Max 2015\libiray.dll

3.12.1.18

Restart 3ds Max 2015

Future patches and releases of 3ds Max will automatically support Maxwell generation GPUs.

      No, this patch only allows iray to render on Maxwell GPU.
      AO GPU in 3ds Max 2015 SP2 does not support Maxwell.
      We hope to see this added soon, we will keep you informed.

      We don’t have plans to update previous releases of 3ds Max at this time as this would require upgrading the previous Iray version(s) to the latest CUDA version, and this would really cut into our current development cycle (and you’re going to like what’s being cooked). Is there any reason that you can’t upgrade to Max 2015?

      1. Yes, There is. Just barely got a new gpu and now my entire program is having issues because stuff isnt compatible with it. I have the student version of which they dont offer 2015. Boned I guess.

  1. I had a subscription for several years. I stopped it last year because of kids, money and frustration about 3ds Max progress 😉

    I’m now learning Blender. Maxwell works on Blender (also with a fix for now). But I don’t want to throw away my first love that easy 🙂
