[Unity] FFD causing strange stretching

mugathur

I've been playing with the new FFD features and they're great. However, we have come upon a problem. While animating our main character, when we use the FFD features in Spine with the unity runtime, it gives our character fat legs. I have attached a screenshot of two setups.

Left: All 4 images using FFD
Right: Mesh unchecked and re-exported

We are using FFD on most images in our scene and this behavior does not seem to happen on every image (or at least is not noticeable). I have stripped the scene down to the most noticeable part (player legs). Please let me know what to do. I have a stripped down Unity project with ffd and non-ffd spine projects that I will upload in a reply.

Thanks so much!

Sorry, but the Unity project was too big to upload so I've just uploaded a zip file to chuck into an empty unity project. (it includes the Spine runtime)

Are you running the newest version of Unity? There seems to be some issues with older versions and FFD.

mugathur

Yup. Fully up to date on version on 4.3.4f1.

Pharan

There were some scaling issues when exporting from older versions of Spine editor. What version is your Spine editor?

The latest version is 1.8.35

Søren

I'm afraid I can't seem to find any problems with the FFD project by importing the json back into Spine. Like Pharan is asking which version are you running? Latest is now 1.8.37

mugathur

It was exported from 1.8.35. The export was crashing in 1.8.36. I'll try 1.8.37 when I'm home tomorrow.

You can't use whitespace trimming in the atlas when using meshes.

mugathur

Thanks, Nate! I'll try disabling when I get home. 🙂

working great! thanks!

I have to use whitespace trimming because my game has too many characters.
Do you have any plan for fix it?
I need both of them. (FFD and whitespace trimming)

Pharan

You can pre-trim the images before putting them into Spine, using something like GIMP or Photoshop.

Hey Nate,
Is there currently a way to use atlas trimming for pngs to which mesh deformations have been applied?

Not currently no. We however want to do something with it, but I don't know what will be possible yet so I can't share any details. Best is to make sure you trim your images before you import them for now.

knish

Thanks! So basically i will need an estimate for the pre trimmed size depending on how much i will be going to distort the image in the mesh? i am assuming the mesh vertices then cannot go beyond the original size of the png?

From the Spine side.... i mean the quick fix here is to have the texture packer intentionally ignore Strip White Space on any image that has a mesh applied to it
