I'm having Reality Export crashes as well.

I only do 'Export Only'.  My guess is that Reality dies somewhere in there and leaves me with a half exported render, then lux dies when I try to render. It says there are no lights.

When I exit Daz, Daz says that it encountered a fatal error.  Hmm... Daz exit trace shows a stack trace ending with "RtUserThreadStart"

 

Hmm... I had been playing with material editing.  I just did a full reload of the original  materials and was able to export... however Daz still gives the same error.  Reality also seems to have gone capoof!

 

For this test render I'm just using Victoria 4.2 with fembot material settings morphs.  1 mesh light, and 1 camera.

Here's the fembot model;

Yup. Poof...  Cannot render in Reality with that simple scene.  Same error.  Cannot export without killing Reality.

(I haven't had any troubles with other render exports, like 'Minotaur' which you just put in your Deviantart forum.)

 

If I'm right... you'll hear from Elianeck..  She loves that model!
