If one renders inside the Max frame buffer, no problems.
However, if one decides to export the scene instead to Indigo standalone (which I prefer), the following message appears:
Code: Select all
Scene parsing error: Node with UID 8 was not a medium node.
Strangely, applying a glass material the first time to an object, and then rendering - it works. But if you stop the render, and then try again, then the above error message comes up. Looking at the .igs file, the first instance when it works, the following appears (which is correct):
Code: Select all
<material>
<uid>7</uid>
<name>Material #27</name>
<specular>
<internal_medium_uid>8</internal_medium_uid>
<transparent>true</transparent>
<arch_glass>false</arch_glass>
<single_face>false</single_face>
</specular>
</material>
<medium>

</material>
Pretty miffed also (as a paid user of Indigo) that four emails explaining this problem to support@indigorenderer.com, have not been answered. As a Max user, is it worth actually my valuable time supporting a renderer of which the Max exporter always has been sub-par?
