I was using LW and Octane quite happily this morning. Suddenly this afternoon Octane flags a license warning saying that it could not find the required license! I have Octane on only one machine and this problem occurred even after a restart. Please see attached image.
Separate issue. Earlier I was getting one-sided polys rendering both sides. I'm using LW2015.3 with Octane 4. 00.0.21 on Win 10. An older version of Octane was rendering backfaces of single-sided polys as clear, a feature that I find excellent for cutaway images.
