In the forum I've found quick note that this has to be done on XML and BIN level, rather than on OBJ and MTL. Is there an example of how to specify a transparent material with different refractive index? I'm particularly interested in flat interfaces with materials are either large parallelepipeds or semi-infinite.</SPAN></P> <P>Would greatly appreciate any pointer or advice.</P> <P>Cheers,</P> <P>&nbsp; &nbsp; Yuri Rzhanov</P> Wed, 26 Oct 2016 13:38:52 GMT https://community.intel.com/t5/Intel-Embree-Ray-Tracing-Kernels/Refraction-modeling/m-p/1065957#M549 Yuri_R_1 2016-10-26T13:38:52Z https://community.intel.com/t5/Intel-Embree-Ray-Tracing-Kernels/Refraction-modeling/m-p/1065958#M550 <P>The crown model uses glass materials.
