New Mental Ray shaders development

[Daniel Brassard]

Little update from ARC

Our success working with the community on this has been very helpful, and we hope to have more news on how we plan to continue the testing and release process next week. As we get closer to release, we have to plan more synchronization with our OEMs (ie, Autodesk).

Now, if AD could properly integrate this to Softimage, provide us with a working string option solution and correct the geo bug, i'll be happy.

You're way too easy to please...

I have been told that, anyway this is only one of the thing on my long list of shaders improvement.

Back to topic... nothing to see here!

there was a mental ray string tool, I can't find the thread ? I was having issues getting it to work.

I've been using the MilA between Maya & Softimage. I'm having an overall problem, the shader setup looks great, except when I apply a diffuse map, it's invisible, I've tried plugging it into the diffuse transmission, into the weight tint, nothing, I shifted around the layers, that breaks the desired look, arghh

Guys,

I've just tried to use this shader, but I got an error message and Mental Ray is disabled for the rest of the session. Does anybody can help me installing this properly under Softimage 2014 SP2?


Cheers

i quote myself here from the beginning of the thread.

new shaders are out as a betaversion.

download the shader here:
http://forum.nvidia-arc.com/showthread.php?12260-Layering-library

installation is like the user ibl:

- mi file in "C:\Program Files\Autodesk\Softimage 2013\Application\phenolib\mi"

- dll in "C:\Program Files\Autodesk\Softimage 2013\Application\bin\nt-x86-64"

i also copied the files from the commom\include into C:\Program Files\Autodesk\Softimage 2013 SP1\Application\phenolib\include

they can be found in rendertree under nodes-->mentalray-->material, all with the mila prefix.

and dont forget to read the docs to know how to setup and how the parameters works because some things changed, like the glossi parameter. ;)


i like the new setup and most important features, importance sampling and correct lightsource sampling without to need a hell lot of rays.
sss works now without a lightmap, which makes it way easier to setup and tune.

edit: dont forget to use arealights. the shaders are designed for this type of light.

Thanks KZin, I followed this, and yet MR crashes...

What mi did you copied into the phenolib folder? mi file is mresent only in the common/include folder apparently

are you sure you have the right mila package? there is one for mr 3.10 and one for 3.11 and you will need the 3.11 version for si4014sp2.

[j3st3r]

Yes. I doublechecked

[j3st3r]

ray-layering-shader-experimental-3.11-183520.13317 this is what I have from the download thread.

[rray]

It does that when anything else but a layer node is plugged into the mila material

[Kzin]

ok, step by step:

layering.dll --> ...\Application\bin\nt-x86-64

layering.mi --> ...\Application\phenolib\mi


and the files from this folder
\ray-layering-shader-experimental-3.11-183520.13317\common\include

go into this
...\Application\phenolib\include

[j3st3r]

Fine. The layering.mi is from the common folder, am I right?

rray: you must be right, I accidentally connected the mila_adapter node, since I had a warning that it should be connected, otherwise it seems to work fine now. Thanks guys the help!

[j3st3r]

So, when I connect mila_specualr_refelction into the mila_layer, MR hangs and then XSI crashes immediately.
