“Should the Carrara plug-in generate an .LXS file”
No, I’ve not noticed the Carrara Luxus plug-in creating any LXS files,.... I only see that with the DS version of Luxus.
CORRECTION: There is an option box for “Specify Path”,. and when that’s enabled,... hitting render,. will open a “Save .LXS” window.
If you hit “Cancel”,... it will open the Lux render GUI and start to render.
If that option isn’t enabled,. it should normally create a render window filled with a blue/green colour,.(not sure why)
then it opens the Lux render GUI
Try the new beta build (above) which apparently allows you to browse for the location of the Luxrender application.
- Users can now choose where LuxRender is.
Hope it helps
