Patience

Confirming Page 82 of the Affinity Designer Workbook, Edition 1.0, reprint 5. Objects --> Blend modes. Regardless, if i go to the Core Skills file and play with the blend mode for the shadow layer or the eye layer, I don't see any visible change to the object. It might be just a bad example from the book that has very minor changes.

I am at Page 82 of the Affinity Designer Workbook and followed the instructions to change the Inner Glow layer effect from Normal to Multiply, Screen, etc... but I don't see any change happening. I have a couple of questions: 1) Where can I see the 2 colors that should take part in the blending effect? I only see one gradient color in the Eyeball layer. 2) What should I see by changing the Blend mode in the Workbook example?
