So If i wanted to use vertex paint. I could only either use 4 diffuse or 2 diffuse and 2 normal or any combination of 4 texture samples? Is this correct?
what tharle meant was that theoretically there isn't a limit of vertex paint channels. I mean, of course there is, but as he said, you could for example use the red vertex paint channel and split it into two. Instead of having values of 0 - 255 deciding which 2 textures to blend, you could use 0 to 127 in order to blend…
pretty sure you could blend as many textures as you want by using if nodes. ie if red is 0-50 then use texture 1 51-100 use texture 2. you get less range of colour information to blend with but as many textures as you want. realistically there's no reason you couldnt put 100 textures in each colour channel if you were…
Yeh you just need to LERP them together like you did your 2 first sets of textures. So you take the output of the 1st LERP you have and plug that into the A channel of a new LERP, and for the alpha of that LERP you duplicate the blending function, except now you use a different vertex colour, and then you plug in whatever…
