Quote - A lot of the memory issues come from the way subdivision is handled in Luxus.

If you have elevated the SubD level in your scene, Luxus adds loop subdivision on the exported objects.  This is in addition to the CC subd already added by DS.

You can switch the loop off in the render settings panel and set the subD to 0 in DAZ Studio. It will then only convert the quads to triangles(if you have a large scene).

This is a more complicated interface that will require the user to be more proficient at setting up an export for Luxrender.

If one puts some time in it, it's quite extensive but definitely worth the effort for the price.
