Export Draped STM in Connect SS4 to LumenRT with good/fair quality?

Hello,

i have installed Microstation Connect SS4 with compability for using STM functions and exporting to LumenRT.

I have a large a STM draped with a photo (several km long railroad), using the STM in Connect SS4, the quality is amazing, and i would like to export this to a LumenRT model, i dont need exaclty as good quality, but a fair quality.

When Exporting to LumenRT, the quality is only good where i am at for the moment, the rest of the model becomes in "bits an pices" with low quality. 

I suspect there should be some kind of function, to set a quality before exporting from Connect SS4 to LumenRT? So that the whole model i shown in a fair quality.

Is this possible?
