Title: tk2d:LitBlendVertexColor Vs Unity:Sprites/Diffuse
Post by: drkucho on March 24, 2015, 06:10:10 pm
these shaders seem to work exactly the same, what are the differences ?

Not looked at the source to Sprites/Diffuse, but when LitBlendVertexColor was written there wasn't an equivalent in Unity. The closest equivalent was way more inefficient.

I was going to make my own post but saw this. We upgraded our project to Unity 5 and now the tk2d/LitBlendVertexColor is no longer working properly for me. Are you aware of this and how can we fix it? Thanks!

What isn't working and what version of tk2d are you using?

2d toolkit Version 2.5.1. The latest on the asset store.

Everything else works fine but we have 1 semi transparent sprite that was using LitBlendVertexColor and it was drawing very wrong after upgrading. http://i.imgur.com/2RUMIkX.png

I switched it to the standard shader and got it looking correct again btw.

Hmmm... could be an issue with the vertex lighting path in Unity 5, we use this path as its the fastest rendering path... I'll look into it.
