MR: what's going on?

[nisus]

Hi jucaro,

 

In the main time I've tried (almost) your first settings

 

GI 50

Photons 100

FG set to 50

Energy 100000

decay 2.0

caustic 1000 (not active)

GI 50

Logarithmic exposures enabled to 65,60,1,1500

Affect Indirect only checked

ideal diffuse (no windows)

 

unaltered max3.1 materials (no windows)

 

unaltered max 3.1 materials (with windows: standard max6 architectural glass)

 

The results are fine for now. I will be changing the materials later, but have to get more insight in MR first

 

I'm gonna try your new settings - from the first image you posted - soon... I'm not so found of the second image. Where does one set the GI range so one doens't need a sphere?

 

From the render preview (exposure control) I see my initial problem of disco spots has returned (on the max 3.1 materials) so I'm gonna try it with the ideal diffuse first...

 

tnx a lot,

Hi Che,

 

Are you using a daylight system? Or just a sunlight? (I'm only trying the sun for now...)

I bump on a few incompatibilities:

 

IES Sun not supported

Automatic Exposure not supported

(Logarithmic is supported)

Radiosity not supported

Texture Baking not supported

 

I can live with limitations, but I was hoping for these things to be compatible (at least, that's how it was told on the official 3ds max launch on the demo).

 

But all in all, the Mental Ray rendering plugin is working very well. Now we still have to learn what it's advantages are over scanline. I guess the faster raytracing, better displacement and motion blur, but I can be wrong. And of course some special shader support.

incompatibilities

Well, for a native max3.1 user I don't feel sad about this... most features are but new :ppp

Hi all,

 

I have been following this post, it's very informative. I'm trying to upgrade to MAX 6 too, so I gave the demo a try. I basically used some of the tips that were posted here and played around with the rest of the settings. The model isn't finished yet, no chamfers, it's raw. Anyway, these are some of my numbers:

 

Render time 4:25 min total.

HDRI

GI&Photons 50

FG 1000

Samplers Min 1 max 4

GI and Photons max radius 256'

FYI ....this probably belongs in 3rd party renderer's, but since i already added to this thread. ...my splotches were caused by an object that had a 3dmax surface style with a diffuse map, but no uvw coordinates. i added the uvw cords, and everything rendered fine.

hi nisus. a similar thing happened to me last wed before i left for thanksgiving. i am just getting back to it now. i will probably just re-start with one of the previous saves before my file went corrupt, instead of trouble shooting what caused the problem.

 

however, if it helps, i am getting errors in my vray dialog box. the errors say:

 

warning: Material returned overbright or invalid color

 

not sure if this is a vray thing or a max thing.
