Overlay layer?

vresu

Hi Spine2d! i would like to suggest a feature layer for overlay. would it be possible to do that?
i am still doing research on vanillaware *beside breath animations (mesh deform) they are also using overlay layer to make the glow effects.
*here is extracted files from dragon crown Figther Guild White layer.. they add overlal filter to that file.

i manage to make mine.. but i am using the wrong method. this is using spine2d.

here is the clip at 6.32

btw i am already researching vanillaware technique around 5 years.. and i am using a lots of 2d tools. the closest and best one is Spine2d so far.
i would really appreciate it if you add overlay layer. with key animations (like alpha).

Best

it already has alpha. key the slot or image(mesh) colour

I also suggested something which would allow a gradient of alpha over a mesh:
ANIMATE COLOR

vresu

need Overlay features beside alpha. alpha is there already.

BinaryCats

what other features do you want besides alpha? colour? because that's the same as alpha

Hello!~ sorry for bad english. i having a hard time to explain it by text. but here is snapshot.
hope you can understand and spine2d team can understand this features.

Thanks

That's a lighting trick and what you called a sprite is specifically a light cookie. I recommend letting your game handle lighting. There you can create a narrow spotlight using that light cookie. If that's too complicated, just simply use linear blending + alpha between that sprite and Samuel. In that way, any character standing on that spot can be lit like this, which is pretty cool.

Spine is not a scene editor, (just remotely in fact :] ).

@SkipperDev hmnn i need em in animation though. since adobe flash can do overlay. because the spot was needed on some spot to make the breath and lighting illusion. its need to have some animation loop to create that. hope that the spince team can add this features.

Spine2d team?? hope u read em.

Cheers

Additive mode is supported in Unity now, Overlay and Multiply are not supported in Unity yet - but they are supported in Spine Editor.

If you're still bent on trying to bake lights into your animation, you're going to have to wait for that feature. Even IF Spine supports it in the future, Unity may not. You have two options: to wait for Spine to support lighting and more blend modes, and Unity to support Overlay; or try one of the solutions above and get the exact same results. Don't bake a light in every animation, instead make one light/particle in Unity and have all characters use it. That is the right way - it exists and it's practical.

Thanks for the input! 🙂 hopefully Spine2d consider as a new features. and yes unity3d cannot do overlay. the closest one is addictive.
might have to wait later if spine upgrade the features.

3 year later.
Any chance we could get Overlay blend mode support besides Add, Multiply, Screen?
It is quite commonly used esp on scenes, but hard to deal with when the overlay layer could not be merged to the background by design. e.g. used as dynamic glow / highlight layer. I really hope this could be supported by spine.

Here is a sample shader code for overlay in case dev need it.

Overlay requires a shader and that complicates rendering at runtime for the user, who may be using their own shaders. We still want to do it, it just needs to be done carefully. We haven't been idle for 3 years, there is an unending queue of things needing doing. 🙂

Also, some game toolkits aren't able to support overlay rendering. We don't want to limit Spine's functionality to the lowest common denominator, but there are many other important features to work on that are supported by all game toolkits.

At a glance, that shader doesn't look like it's doing overlay.

Right, my bad. I am tricked by the title of that github page.

Here is a more realistic sample reference just for correction. Ignore it if overlay is not a priority.
