How do I add inner shadow better (see example)?

[Gary-ser]

Hello,

Please look at the robe below. I added inner shadow. But I want to have creases in the robe, so that the shadows would show where the fabric would fold a little, going up vertically from the bottom of the robe where the fabric is wavy.

So far, attempts to add more nodes to get those creases have been a disaster. And sometimes the shadows falls the wrong way when I do that. Even without that issue, the node editing just ends in a mess.

Is there a better way to approach this?

Thank you.

Hello Gary-ser,

For example, you can draw four very thin lines and apply a slight Gaussian blur, as I did. Then adjust to your liking according to the desired effect.

OK Reglico, thanks, I will give that a try. 

 

P.S. (Later) Yeah, that did it, thanks!
