No shadows with shadow map lights

Recommended Posts


So when I save the image with lights shadow option to depth map shadows, I get no shadows at all. Ofcourse this renders fine inside houdini, only saved images have that.

Ray traced shadows on the left and shadow map on the right

Have you opened the shadow map .rat file and checked what's stored in various channels? Is it just black or is there some strange looking data? You can also use viewport mode "look through light" in order to verify that the object is in the light's field of view.

BTW in order to get Mantra to use shadow map in the IPR renderer you need to attach "vm_iprraytraceshadows" rendering property to the mantra node and disable it. Otherwise only ray traced shadows are used for the IPR.
