Multiple Mesh Export from 1 Spine file

IndieDoroid

Hi,

Is there a way to export multiple meshes from 1 spine character?

For example:

Export 1 - legs \ arms
Export 2 - head \ torso

The goal is to have Export 1 be able to cast shadows and Export 2 to NOT cast shadows.

Thanks

Hello IndieDoroid! I'll assume that by exporting multiple meshes you meant exporting multiple atlases.
You can do so by using texture packer and having two separate folders with their own packing settings.

OOOh! I'll try it out . Thanks!

Hi @Erikari I looked into the texture packing page and don't think it's what I need, unless I didn't catch something. :confused:

Basically I'm wondering if it's possible to separate which objects can cast shadows and which cannot.

For example this goblin, I'd like the body to cast a shadow, but not the balloon. These are all one atlas.

Is that possible? :wounded:

Thanks!

This seems to be more of a runtime question than an editor one, can you tell me what runtime are you making this in?

Chiming in for the runtime side, I guess you are using spine-unity. 🙂

On the atlas packing side, you would need to make sure that the non-shadow-caster objects are on a separate texture atlas. In Unity, this will result in a separate submesh for the balloon, where you can then change the material properties, such as the shader parameter Shadow alpha cutoff to a value of 1.0. Then you just have to make sure that the alpha value of the balloon is not 100% opaque but contains a little bit of transparency.

Thanks for the answers guys

Hi @Harald, yea I think it's a mix of runtime and editor? :think:

@Harald Is this what you mean 🙂

Is it possible if the character has multiple skins, which in turn have in their own respective folders.

In the link http://esotericsoftware.com/spine-texture-packer, it seems like I can just specify 1 input folder?

Could you please explain how I could achieve this?

1) Multiple skin on character(each skin has their own images in a folder) can cast shadows

2) Balloon cannot cast shadows

Thanks so much! :nerd:

When you run Texture Packer manually, you would have to run it once for every folder.

Another way would be to export atlas textures along export of the skeleton:

Select Spine - Export
Select either JSON or Binary
under Texture atlas: enable Pack and change Attachments (as shown in the screenshot below) to Image Folder.

hmmm its still a bit foggy on my end. But I guess I'll have to try it out first and see if I can get it.
I'll let you know how it goes! Thanks 🙂
