OSL goodness in Vray

[mayanic]

@mayanic:
Your problem is that you're using the wrong node type - VRayPluginNodeTex:TexOSL instead of VRayTexOSL.
If you create the correct node it will work as expected. After you change the output as mentioned by others.

sorry for the delay
i still don't get the k value to show up

there is a node (Create > V-Ray > Create form V-Ray Plugin) called OSLTex. should i use that one?

Network locations as well. Thank you for your response!

Are you both using the installer or are you using V-Ray from a network location?

Do you have a variable like VRAY_OSL_PATH_MAYA2014_x64 set?
It should point to the folder that contains oslutil.h and stdosl.h files.

Network location here - that explains it..! Thx

Im getting this error, where do I set up the path?

// Error: OSL shader error: OSL include path not set

Did you work out why this was happening? Same thing here, can't find any info on it...

hmm I did test it in maya 2014 and an older version of VRay, nightly pre 3.2.
do you know what it was that was causing problems in maya?
I'll test again later when we are all up to date here.

"Col_Out" needs to be called "result"

I tweaked it so it would work in Maya

what about if you want to use the fabric one where will you connect it?
thx

just follow the instructions here:

You need to turn off the Use Fresnel button and change in VRayTexOSL in Color Output of result for Col_Out. The same as this:

I hope this helps.

Right. It would probably be good to update the shader from this:


output color Col_Out = color(0.5))
{
float thetaCos = abs(dot(-I,N));
float red=fresnel(n[0], k[0], thetaCos);
float green=fresnel(n[1], k[1], thetaCos);
float blue=fresnel(n[2], k[2], thetaCos);
Col_Out=color(red, green, blue);
}

to this:

output color result = color(0.5))
{
float thetaCos = abs(dot(-I,N));
float red=fresnel(n[0], k[0], thetaCos);
float green=fresnel(n[1], k[1], thetaCos);
float blue=fresnel(n[2], k[2], thetaCos);
result=color(red, green, blue);

}

that way it will work by default in Maya.

i already posted a pics of my node editor / ae ...

i just connected the osl-texture to my reflection color and plugged a osl-file in there
but nothing happened

Can you post an image of the OSLTex in the attribute editor? Do you get an error message when you load the OSL?
