[UNITY] Shadow of elements with opacity 0

dTb

Hi!

I am a pretty new Spine user. This software is awesome!

I have a question: elements with an opacity set to 0 are casting shadows in Unity, is it normal, is it a bug, or am I doing something wrong? If this is an expected behavior, is there a workaround?

For example I have a hero:

when he's idle, weapon 1 is visible and weapon 2 is invisible (opacity 0)
when he attacks, weapon 1 turns invisible and weapon 2 visible.

My problem is that weapon 2 is casting shadow when idle. Of course in this particular case I can use only one weapon slot and switch images (but if I do, I guess I will not have a nice fade effect between the 2 sprites) but for some other elements I cannot use this trick.

Thanks in advance!

You should turn the attachment off, not set its opacity to zero. You can use Skeleton Utility's Slots dropdown to debug and test to your hearts content in that regard.

Ok, I see.

But with this solution we cannot fade the image from one to the other.
No matter, we will figure something out.
Thank you for your help with the shadow, at least we understand this better!

Sure can, just turn it off when you're done fading. Also unity doesn't support translucent shadow intensity beyond the per-light strength setting
