Heya, there’s an issue I’ve come across where calling updateColor4 on a UniformBuffer isn’t working. EG in the simple material plugin example below the cube should be red if it’s working but instead is white. If I comment out line 50 and uncomment line 51 to instead use updateFloat4 and pass the r, g, b, a properties for its params then it works as expected. Also using updateColor3 to update a color3 uniform works as well.
Actually it’s updateDirectColor4 that you want to use. updateColor4 is taking a Color3 + float as parameters… That’s a bit unfortunate that updateColor4 does not take a Color4 as a parameter, but I guess there are some historical reasons behind this choice.

TYVM that solves it then. 
Def agree thou that it’s an unfortunate, and IMO confusing, naming inconsistency…
we can provide an overload with Color4
