Weird edges on images after export and imported to GameMaker

leifolini

Hello, I'm using the latest Spine version with Game Maker Studio 2.
When I import my skeleton as a JSON file with atlas, some of my images gets an edge that I don't want. I thought it might have something to do with the export settings, but I've tried a lot of different settings, but it's still there. Please see the attached screenshot.

I want the arm to blend perfectly with the body, like it does in Spine. But after exporting, it doesn't work. I'm not talking about the black outline of the seperate images, but the thin gray line on the top of the arm that should just be green.
Any help or suggestions would be much appreciated.

Try to deactivate premultiply alpha when you export, it might be the cause.

Hi!
I have the same problem in Game Maker Studio 2:

My export settings:

My grapics and sprite settings in GMS2:

I tryed different variants of settings but the issue still exist 🙁

Could it be that GM has since implemented pre-multiplied alpha? I see the setting in sprite0 under Texture Settings in your screenshot. Export with PMA from Spine, then check that setting in GM.

Unfortunately it didn't help, I tried. I'll ask on GMS forum but if somebody here will post Spine export settings or GMS settings I'll be very grateful, sure I'm not first who meet this issue )

It makes no sense that the black outlines would appear with Premultiply Alpha disabled on both Spine atlas export and in the GM settings. I'm also not sure what their checkbox means— does it mean treat the texture as if it has premultiplied alpha, or does it mean apply premultiplied alpha before rendering?

If you're going to the forum, the question to ask is probably:
"Are these black outlines a premultiply alpha problem in GameMaker? For Spine assets, should I export the texture with premultiply alpha enabled or disabled? What should my settings be?"

I tryed to do it with I think all possible checkboxes combinations in Spine and in GMS but it didn't help... Also GMS requires Spine 3.4 to avoid errors but it didn't help too.
I'll post here the result

After thousand attempts to reapair it: just delete the Sprite with spine skeleton in GMS and create it again. GMS saves settings from first loaded skeleton and doesn't update it after you reload the skeleton with edit :giggle:

So you're saying you fixed it?

Yes. I did it 🙂
