Shadow catcher with opacity map
Posted: Thu Jan 09, 2020 8:07 pm
hi Paul.
Previously in Octane v.4.5.0.111 we were using Diffuse material with shadow catcher ON. We also applied mask in opacity channel - to controll ground shadow and keep it away from edges. Now, if I try to use same technique in Octane v.2019.1.4.115 - it doesn't work - if I put image mask in Opacity channel , shadow catcher doesn't work anymore. I see that there's a specific Material type for this "Shadow Catcher" but it doesn't have an Opacity channel, where I can put texture mask.
Question: how can we have a Shadow Catcher with Opacity channel, so we can control how far shadows go??
Thanks,
Igor
