3ds max 2011 is hanging when render

[hshfx]

Hello ALL!
Trying to render only some forest but 3ds max 2011 is hanging at first seconds of render.
It's always hanging at "Pre-Processing scene" task. What can I do in this situation?
Thank you!

It seems that the Mental Ray shader is not loaded.

What Forest version are you using, 3.3.1 ?

Can you find these files in the Max folder ?

<maxdir>\mentalimages\shaders_autoload\mentalray\include\Fshader3.mi
<maxdir>\mentalimages\shaders_autoload\mentalray\shaders\Fshader3.dll

[hshfx]

Yes, I'm using Forest Light 3.3.1 and I have files in this folders

Please, make a zip with the content of the folder <maxdir>\mentalimages\shaders_autoload\mentalray, and send it to support@itoosoft.com.

One more thing: can you see the content of the file Shader3.mi opening it with Notepad ?

Sorry, i have not received your rar file, probably it was block by some anti-spam filter. I just sent you a personal message (see inbox in your profile) with an alternative email account. If possible, please include the full content of <maxdir>\mentalimages. I want to check some MR configuration files included there.

Although i'm not sure why, it seems that Max cannot find the Mental Ray shader in your configuration.

A shader is based in two files, a definition file (.mi) and a library (.dll).  By the error message, Max cannot even to find the .mi file, although the FShader3.mi seems to be correct. On my side, i only can reproduce this problem deleting this file.

Also it's possible that the configuration file which define the shader folders is missing or corrupt (<maxdir>\mentalimages\rayrc). Have your other computer with Max installed where to copy the content of <maxdir>\mentalimages ?

I really don't know what it was, but when I had reinstall 3ds max in C:\Program Files it began working! Before it 3ds max was installed on another hard drive. Then I had reinstall 3ds max again on drive D:\ and it works again!
Forest Pack working very well! I think 3ds max was not installed correctly in first time...
In any case, thank you for your fast help!!! I'm very sorry for putting you on the wrong way!

I think the topic can be removed

Great. I'm glad you solved it
