Maya 2017 Mental Ray render stuck at 20% everytime

[Anonymous]

I tried to render frame this mesh up to 3 times now. I don't know whats wrong with it. Can anyone try to render this for me and help figure out what's wrong with it?

Hi!

Maya Version (update?)

Mental Ray Version?

Here on Windows Maya 2017 update 4 it works fine ( open scene, hit render).

What happens if you render without Smooth Mesh Preview enabled ?

What happens if you disable/remove Texture files?

What happens if you assign one default material to all objects?

Hi, I'm currently on Maya 2017. I don't know which Mental Ray I'm currently using, how to do I check which version I'm using? Also here is the error from Output Window

 ============================ Rendering frame 0 (total 1 frames) ============================

Hi!

"Hi, I'm currently on Maya 2017"

Which one, there are 5 Versions (incl. updates) ?

Help -> About Maya

Plugin-Manager for Mental Ray Version (i).

and again:

1. What happens if you render without Smooth Mesh Preview enabled ?

2. What happens if you disable/remove Texture files?

3. What happens if you assign one default material to all objects?

Okay so I have

Maya 2017 Update 4

Mental Ray 3.14

How do you rendered without smooth preview?

But I tried to apply all object with one material and it rendered. So I guess my blinn material with the texture file is the issue here.

Is there any way for me to upload my import my material file here?

Hi!

You don't know how to enable/disable Smooth Mesh Preview? (With default Render Settings Mental Ray uses this setting also for rendering)

Please read the Maya Online Help / Documentation for more details.

I have all materials with your scene, what i am missing are texture images.

Upload images in a ZIP-file or try to directly attach them.

Hi!

The problem is a combination of several things:

1. Using only one big object with multiple materials (not much left for the renderer to optimize)

2. Mass transparency, multiple faces of the same object behind one other.

3. Very high quality settings for Rendering (Using GI Next and high value for Indirect Lighting, Samples and Ray Depth)

4. Using Maya Materials instead of Mental Ray materials.

Please optimize the scene. You will get a much lower render time and no errors.
