anyone knows how to properly set up the mib_ray_marcher node from within Maya ?

i have managed to render a ray marched texture in a cube - but the wiered thing is that the cube is totally opaque

what should i connect to the shader attribute of the node ?

that's what i've got so far

the shading network

basically that was just a wild guess - i managed to get a parti_volume shader to render properly and from there i tried to apply the same setup to the mib_ray_marcher node

i am not sure but you can have a look in the scene file in that tut.. he uses ray marcher as well for the volume caustics..

as far as i can see he is using the parti_volume and parti_volume_photon_node and not the mib_ray_marcher node

Hmm I give up.

I played around with your scene for a while then created one of my own using the 3D Crater texture (looked cool!) but transparency just doesn't seem to happen.

thanks for taking a look at it - sure the ray marching looks promising - i think i'll get the book on mental-ray to sort this things out
