1) Export .mxs file from Softimage, with a light being used to determine sun direction (physical sky)

2) Import to Maxwell 'Studio'
The light used for sun direction (Track Object -> 'Use Selected') is not imported to Maxwell 'Studio' - the scene renders with no light source (black).

3) Import to Maxwell 'Render'
If I open the same .mxs file in Maxwell 'Render', it is recognized and the scene renders with the light. It also works when using preview button in Softimage (but that uses 'Render' as well).

Maybe this is known thing. There doesn't appear to be an option to track an object for sun in 'Studio' (that I can see). I only happened on to this trying to trouble shoot something with materials, which can't be done in 'Render'.

Yes Studio doesn't have that functionality for now but I think in the upcoming release of 2.6 where you can now also set the Sun position via angle in Studio, your scene should render fine from Studio as well.

Thanks for the reply! I'll look for it.
