Hi i've found sl shader on Pixar's site, and i'm trying to convert it to otl:


surface
bake_areas( uniform string filename = “”, displaychannels = “” )
{
normal Nn = normalize(N);
float a, opacity;

a = area(P, “dicing”); // micropolygon area
opacity = 0.333333 * (Os + Os + Os); // average opacity
a *= opacity; // reduce area if non-opaque

if (a > 0)
bake3d(filename, displaychannels, P, Nn, “interpolate”, 1, “_area”, a);

Ci = Cs * Os;
Oi = Os;
}


but when i try to convert it to otl using slo2otl.py i have error:



Fatal Python error: Py_Initialize: can't initialize sys standard streams

any ideas how can i import slo shaders in other way ?

may be your not typing a right command..

the command has to be like this
slo2otl.py -l name.otl name.slo

slo2otl.py takes .slo files as the input. This means the shader should already be compiled from the .sl source code.

Could you be trying to run slo2otl.py on an uncompiled shader?

slo2otl.py command doesn't compile shader, otl is just a wrapper for slo to use in Houdini.

That's what I was getting at. I suspect bareya is trying to run slo2otl.py on shader code that has not yet been compiled.
