So basically I have a sky model and I want it’s texture to fade from this texture (default one):
To this texture:
Let’s say that fading isn’t really the problem here (I will probably use a function lerp) but the main question is how to add the secondary texture to the model setting it’s transparency to 0 then using my function lerp I will decrease the primary texture’s transparency and increase the secondary texture’s transparency, so what function method should I use to accomplish the transparency goal?
