Black reflection with mi_car_paint and standalone

[som3d]

Hi all,

I get a black reflection pass with mi_car_paint_phen_x_passes via Mental Ray Standalone 3.8.1.28. Mental Ray for Maya has no problem. I use no IBL.

My setup:
Maya 2011 Hotfix 3 x64 on Win7 64bit
Mental Ray Standalone 3.8.1.28 on Win XP SP2 64bit

Is it a bug or is there a solution for this problem?

Hi,

I updated to Maya 2011 Advantage Pack and MentalRay Standalone 3.8.1.33 (SP1).
But I still have problems with the car_paint reflections and get a lot of Warnings and two Errors.

I did default installations of Maya and MentalRay Standalone. What's the problem?
I need help!!!

The base.dll shader library is required but not loaded according to the log. Check the .mi file for a related link command, and add it if it's missing.

Thanks Steve for your reply.

You are right there is no link command in the mi-file. In the meantime I also noticed that I have a linking problem. But I don't want to add the missing link in every rendering...
In former versions of MR STD I used a ray.bat to set MI_ROOT (and MI_RAY_INCPATH/MI_LIBRARY_PATH) to a network path where a customized rayrc link standard and customized shaders. With MR STD 3.8.1 I ran into an license problem when I set MI_ROOT.
Is there any documentation how to get this network solution work again?

Note that a rayrc file is being parsed at:
C:\Program Files\Autodesk\mrstand3.8.1-adsk2011\bin/rayrc

Try saving the original rayrc, eg to rayrc.orig and then putting your customized rayrc there.

That said, its odd that there was no loading of base.dll. For full debugging, try copy and pasting your rayrc as well as the top of the mi file where the extra link and $include statements could be.

Hey Bart, thanks for your reply.
I did how you suggested and it works fine now.

If anybody has a solution to set MI_ROOT to a network folder and parse the rayrc from there I'm still interested.

This seems to be a bug in Maya. If you use a mr physical light you don't get reflections on car paint. If you add a mib_cie node to your scene (don't connect it, just add one in the hypershade) then your reflections will work fine.
