Re: sky shader and clouds

[Pingo <pingo(at)pingofilm.dk>]

pete you rock. It works.

I'm totally proud of having actually typed something into an spdl that works... just like that:-p

now if only someone could explain how the Sun Direction works... Is it XYZ?... maybe a new thread for that... and can I link it to the position of a Directional? with the Physical_Sun

cheers

hows this screen grab?

<sky.jpg>

i used the sky from the image provided here
http://mentalraytips.blogspot.com/2007/02/clouds-with-mental-ray-sky.html

plugged that into a spherical Environment.
then added a changed range left the old value from 0-1 the new value from 0-10  then plugged that into the Physical sky shader.
that should work.
move the Physical light around and the clouds change colour too...!!

Think you could post a grab of your rendertree with this working, Daniel?  Would help alot.

Okay, I'm in the rendertree.. I can connect a texture to the haze parameter, xsi inserts a color to vector node inbetween.  I cannot apply spherical mapping or anything, and the rendered image doesnt seem to change.

I know I'm missing something simple.. but what?

adrian,

open your rendertree and then add a texture to the haze.

it will work from there only. you cannot attach the texture in the ppg.

 

just ask back if it does not work,

Thanks, Daniel..  I made the change to the spdl (after making a backup) and saved it back out.  But I dont see how it made Haze texturable.  Do I have it right?

    Parameter "haze" input
    {
        GUID = "{A057D5D1-B526-486F-A749-F83EBA55CFD3}";
        Type = scalar;
        Value = 0.0;
        Texturable = on;
    }

When I initialize the skyshader from the Pass->Edit menu..   the dialog looks the same.

hi adrian,

you can find the spdl here:

C:\Softimage\XSI_6.0\Application\phenolib\spdl\mibase\mia_physicalsky.spdl

 

have fun,

daniel

i stumbled across this tip about connecting clouds with the sky shader in XSI.

http://mentalraytips.blogspot.com/2007/02/clouds-with-mental-ray-sky.html

he describes it as
"as a spherical environment map plugged into the haze parameter of mia_physicalsky. That's basically it!"

the mia_physicalsky in xsi 6 doesnt let me plug anything into the haze value, so i edited the SPDL from this

    Parameter "haze" input
    {
        GUID = "{A057D5D1-B526-486F-A749-F83EBA55CFD3}";
        Type = scalar;
        Value = 0.0;
    }

to


    Parameter "haze" input
    {
        GUID = "{A057D5D1-B526-486F-A749-F83EBA55CFD3}";
        Type = scalar;
        Texturable = on;
        Value = 0.0;
    }


but i can't seem to get it to work. has anyone tried?
