Unity - new AttachUnitySprite attachment doesn't appear

wyman036

So I've been trying to get the new AttachUnitySprite function to work.

I followed the instructions in the youtube video:

It all appears to be working, expect the sprites that I attach will not visually appear in the game.

I've looked into the data in the debugger and the attachment appears to be added in the spine skeleton properly, and the material gets added/created in the inspector (along with showing up in the slots value of skeleton utility)... so I'm not sure where things are going wrong. Any ideas?

Someone encountered this in Unity 5 recently. Turned out that he was using Skeleton Lit shader for his main skeleton, and the default material for Sprites is Skeleton. use the optional 3rd param to make sure the sprites are using the same shader as your main skeleton.

Hey Mitch, thanks for the quick response. Greatly appreciated!

When I looked at my project all my materials were using the same (default "Spine/Skeleton") shader. I looked around some more and I realized that my 'pixels per unit' value was 100 by default and it was making my images super small. Setting it to 1 made everything look right. I thought I had looked for this before but apparently I didn't look close enough.

At that point the attachment's rotation was off (found out it was due to the bone it was attached to being rotated).

Also the transparent parts of my attached sprites had a slight blue tint to to it. I tried out a few different shaders and found that the "Spine/Bone" shader didn't have this problem so I'm applying that shader to all my sprite attachments. Not sure if that's what I should be doing (feel free to chime in if you know a more proper fix for that) but it works.

Thanks again!

Make sure you're using a Packing Tag to ensure the texture actually gets packed. If not, make sure your source image already has pre-multiplied alpha (you'll likely need to make it a TGA or TIFF file to do that with most programs like Photoshop)
