Hi guys,
I am trying to use renderman light shaders by adding light shop parameters to light or by light template but both seems not working,

I have tried using available renderman light shaders in houdini and .slo shader converted into otl but both seems to be not giving any results.

I could use surface shaders but not light shaders any idea why is that, also I couldn't output my render to mplay (by setting display to md).

any clues..?

cheers,
Junaid

Have you set your “Shader Path” on the renderman ROP?

This is usually a list of dirs. ie. $JOB_ROOT/shaders/rel:$RMANTREE/lib/shaders

I believe this can also be handled by setting $HOUDINI_RI_SHADERPATH

yup I have $HOUDINI_RI_SHADERPATH set in my env, that is the reason I could acess my surface shaders, but not sure why i can't have light shaders working similarly

woo.. I just checked it, I was loading it with the wrong env, cheers for pointing out
