same problems here!!
no DOF and the render view is different...
I get great results using DOF!
To get the DOF working, attach the MXcamera attrib to your cam and lower the F-stop value. You have to increase the shutter to avoid overexposed images.
Also the emitter shader works fine!
I have no probs using it.
Sometimes the view doesn't match the maya view.
And hidden objects are exportet to the MXS file and rendered by maxwell.
I experienced the same probs.
I have also problems using the absorbtion and scattering values of the diffuse material. They have no effect in the rendering.
I addition the dielectric material casts shadows like a solid object, and the maya plug doesn't yet support the new features of the last update.
But hey, don't forget ... it's an alpha version.
And for an alpha release the results are great!
Even the rendering speed and the achieved quality of heavy scenes is insane!
By the way: does anybody know the function of the PHASE attribute of the dielectric material and the SM value of the physical sky ?
