Glass material appears as black

[Gerard_S_]

Hi,

I am using EMBREE (for a research project)  to render a architecture scene in which I have 2 glasses on a table. It was originally a Blender project, which I exported to an OBJ. I substituted the glasses OBJ material by a EMBREE Glass material , but when I render the scene the glasses are rendered as completely black. The code for the glasses is below as well as an output of the renderer after 50 frames.

Does anyone know what I am missing or doing wrong?

        <TriangleMesh id="183" name="mesh183">
            <material name="Glass.001">
                <code>"Glass"</code>
                <parameters>
                  <float3 name="transmission">1 1 1</float3>
                  <float name="etaOutside">1</float>
                 <float name="etaInside">1.45</float>​

                </parameters>
            </material>
            <positions ofs="10472976" size="103426"/>
            <normals   ofs="11714088" size="0"/>
            <texcoords ofs="11714088" size="0"/>
            <triangles ofs="11714088" size="206848"/>       
 </TriangleMesh>

Never mind, I was being very silly and was not using enough depth for the path tracer, apologies, keep up the great work
