thanks for sharing your mentalray expertise. i'm not sure if it's kosher to ask random questions here, but it seems fruitful given the past entries.
i'm brand new to mr, and i'm getting some odd hangs when working with materials. when mr is rendering the mat editor, switching between materials takes significantly longer, and specifically, whenever there is a blend or multi-sub in the editor each click takes a good 10-15 seconds. this behavior is apparent in both max9 and max10 (2008).. is this common? are there any solutions or workarounds?
I don't have an official explanation as to why a multisub or blend material would slow down the material editor. I guess if they included multiple raytraced sub-materials then it would simply take a little longer for mental ray to render those preview spheres in the material editor...beyond that, I don't know.
At any rate, I'd think enabling the manual update switch on the material editor would speed things up again since you'd only refresh the material preview when you wanted/needed to.
OMG, you are disgustingly brilliant! Very realistic models. Thanks for your help on my mentalray problem. I'm certain it's one of the things you mentioned.
the "tutorial" you gave about using sky bitmaps on an inverted sphere works fine with p/graphic exposure, only problem i'm having now is that my mental ray sun is having no effect at all
i have followed tutorial except for adjusting to p/graphic exposure
i think i'm missing something really small (or maybe not)
"when you are using p/graphic exposure do you have your gamma set at 1.8 regardless of what it is you are rendering??"
Yes I do. Then I use either the gamma/gain utility or the gamma override option to properly configure my linear gamma 1.0 items like .hdr's and/or bump/displacement maps.
Hi Jeff, I have one problem with the mental ray Arch&Design Material when I check on the option Fast Interpolate. I post my problem in the post http://forums.cgsociety.org/showthread.php?p=4999627#post4999627, i'm trying tofind one solution for this but it's hard. If you knos one solution for how I solve this problem, can you help me?
I m working mainly with Arch & Design Material in Max 9 (MR 5). I hear that in Mental Ray is more powerful in Max 2008 (MR 6). Please tell me Should I Switch to Max 2008 or continue with Max 9 in order to render "Interior" models efficiently. R u working in MAx 9 ior Max 2008?
Hope you get that water issue resolved.
