Okay, I have encountered an extremely frustrating problem here :annoyed:
I have to make some CG fruit.
One of these fruits is a peach, and I have a cool texture for it so far, which I am happy with.
Now, in order to get the peachy look working good, I added a (angle incidence) gradient to the colour channel that gives a whitish edge to the peach, thats visibility is then controlled by another gradient on top of it, that is set to light incidence, and is using alpha blending.
This is basically a cheat, but it works. It looks cool, because it gives that nice white edge where the light is hitting it (I would have used only a light-incidence gradient for this fake highlight, but I found it was too spread out, which is why I used an angle incidence one instead, in case you are wondering).
Now, this looked cool.
However, as I am doing all the textures procedurally, I needed to unwrap the peach to make some alphas for some of the colour procedrals, to place them properly, because with peaches, the colour in the crease along the one side is always darker, and around the tops and bottoms it's lighter and so on and so forth. Anyway, back to my problem:
Since I unwrapped the damn thing, the gradients don't seem to be working anymore :sad:
It's not getting that cool lit edge. Even if I switch off the layers with the alpha I made from the UV, it's still not showing up.
Has anyone else had this problem????
And it's weird because I have 2 peaches, and I only unwrapped the one, but they both use the same surface. And the one that I did not unwrap still has the gradient showing up...
Here is a low quality render, but you can see my problem:
