Sorry my english first,

Mental ray keeps sending me this mesage: MENTAL RAY RENDER DIAGNOSTICS: Performance - ZBrushDispMap has a resolution of 4096x4096 which may be inefficient. - If ZBrushDispMap is not a memory mappable file, use imf_copy to convert it to .map format, to improve the performance. - ZBrushNormalMap has a resolution of 4096x4096 which may be inefficient. - If ZBrushNormalMap is not a memory mappable file, use imf_copy to convert it to .map format, to improve the performance. - ZBrushTexture has a resolution of 4096x4096 which may be inefficient. - If ZBrushTexture is not a memory mappable file, use imf_copy to convert it to .map format, to improve the performance. // Warning: 6 warnings, see script editor for details. // The mental ray render just worked once, then started sending this mesages and i already tryed at lower mapsize, please Help Windows XP Maya 2011 Zbrush 4

Hello Rocco

Are you just using GoZ or are you exporting a 32BIT map? What your error is telling you is that Mental Ray prefers a .map extension.

Mental Ray is running out of RAM when rendering.

Now Maya is suppose to be automatically converting any tiff file into a .map but you have to turn the converter on in Maya 2011.

Go to your Setting/Preferences>Preferences>Render tab

Turn on Use optimized textures

Try that and let me know.

Ok, i tried the way u sayd, i turned on the Use optimized textures, but after rendering says the same:

MENTAL RAY RENDER DIAGNOSTICS: Performance

  • ZBrushDispMap has a resolution of 2048x2048 which may be inefficient.
  • If ZBrushDispMap is not a memory mappable file, use imf_copy to convert it to .map format, to improve the performance.
  • ZBrushTexture has a resolution of 2048x2048 which may be inefficient.
  • If ZBrushTexture is not a memory mappable file, use imf_copy to convert it to .map format, to improve the performance.
    // Warning: 4 warnings, see script editor for details. //

So i think maybe ill start using C4D because i tryed Goz with C4D and i didnt had any trouble rendering and at C4D is not so much complications, its a shame because i really wanted to doit at Maya.

Thanks

Ok this is just a warning. You should still get a render. How many polygons is your mesh in ZBrush?

What is your subdiv approximation setting at?
