Greetings. I have 2 issues connected with shadow catcher.
1. Why do I get strange shadow like this?
1st image - flat render with background. Normal shadow.
2nd image - alpha render added on a solid in Photoshop. Shadow is awful.
2. Why I can't apply material with shadow catcher to an extruded spline surface. Even when I turn current state to an object - it just disappears in render with applied shadow catcher.
