Hey! I'm mostly an artist myself (been self teaching c# and unity) but I'd be happy to help if I can. Could you explain specifically what you're having a problem with or specifically what it is you want to do?

I already see the problem. The blending modes that you set in spine DO NOT come over to unity. That's the reason you guys are hitting snags. You can set blending modes in spine just to make sure things look right before exporting and stuff, but ultimately you just have to do it in unity.

step1 - in unity create a skeleton animation in your hierarchy.

step2 - add component 'skeleton renderer custom materials'

step3- make a new material. You can use other shaders, make your own, or just use the ones provided by spine. So for instance lets make a multiply layer. Make the material, select shader/Spine/PMA Multiply. Then, add the texture you exported from spine to the Main_Tex of the material/shader (if youre using multiple texture sheets per image, you just need to make multiples if you needed things from all of em - otherwise just chose the 1 with the thing you need multiplied).

step4- back in the skeleton renderer custom materials... if you need to make ALL of a texture multiplied (like say, you exported all your shadow layers in 1 image, and all the base art on another image) you could simply just override whichever material you need to. if you need to access a specific slot from spine, that's just at the top under custom slot materials. Either way, simply drag your material into the material slot provided.

try it out with other shaders as well and see what kind of effects you can get/what works for you!

no problem!

also, none of this is programming - its all just unity. If your dev's background is mostly in programming, you should actually be helping out on the unity front too. If you know your way around photoshop youll be able to learn unity's set up way faster than he likely can (its all very visually based and I think easier to grasp than most of PS's shenanigans).

Hello, we have a problem with the component called "skeleton renderer custom materials"
I want to make the eyes of the Ant Queen glow red using a custom material. There is a special blurred attachment on top I made just for this.
It works perfectly fine on all the other skeletons , as you can see the foot of the character is white, but it does not work on the Ant Queen skeleton for some reason. We tried restarting the editor, re-exporting and re-importing but cant figure out why this skeleton is the exception.
Any ideas?

@GMC In general please don't necro a 7 year old thread unless you have good reasons for it. Many issues from the past have been fixed already and old workflows might be deprecated. Just create a new thread instead. In your case, the title also does not suit your question.

Regarding actual question: Unfortunately it's impossible to help based just on these screenshots. A quick guess is that the Slot Name is wrong and thus targeting the wrong slot. You can send us a minimal Unity project which shows your issue as a zip file to contact@esotericsoftware.com, briefly mentioning this forum thread URL so that we know the context. Then we can have a look at it.
