Has anyone come across this.
When saving shadows, if you have two lights and one of them is not set to save shadows you get the following error. If you set them both then the error goes away.
I just left it on on both for this scene but it could be troublesome.
Thanks
While I agree that the error messages are a bit cryptic and could be better, the first thing you should do after enabling the [>Save Attenuation Maps] checkbutton would be to press the [Explore…] button next to it and make sure all entries are not red.
If you don’t have all lights set up with Krakatoa Shadows and valid paths, you should not enable the Attenuation Map saving.
