It’s very tempting to think the add node adds two textures together, but it doesn’t.
If I do this:
you can see I just get a white box.That’s because one texture is already white, so if I add to it, nothing happens ( white is everything on full, nothing left to add ).
But see what happens when I multply:
Multiply, is how you add textures together.
Addendum: If the textures don’t touch each other, then add would work. ( If they don’t occupy the same space ).
Hello everyone,
So I have been trying to make a material with two different textures:
One of them is a eye texture and the other one is the eyelash.
I tried making the eyelash red so I can pick the channel and paint it with other color, then “add” the eye texture to the base color, but for some reason, it doesn’t work well.
I attach some images : One of the code + the end result in Unreal Engine and the other what I want of result in Photoshop.
Can someone help me? Thanks!
Try multiplying the RGB channel of the eyelash by a vector3 parameter. And make the vector 3 below in the grid a parameter. Then the color is capable of being changed.
One question: why is the eyelash a circle?
Maybe this is what you’re thinking of. If the components are separate in the channels, then you can use add:
I was doing this method, but another thing I’m doing is that I move the eye to animate it (with two constants and texture coordinates).
If the eyelash and the eye are in the same texture, the eyelash will move too, and I don’t want that. But thanks!
So… I tried and it doesn’t work for some reason.
It’s hard to tell exactly what you have in those channels. I don’t suppose you could add them as attachments?
In any event, you could do the same thing I have here, but with two textures.
I think you didn’t understand at all: I don’t want to change the color of the eyelash, I want to combine my two textures in one material.
P.d: The Eyelash is in a circle form because the eye it’s for a cartoon character* That’s his original eyelash.
Okay, I solved it!
I just add a OneMinus and later a Multiply and it works! Thanks everyone!!
Ok, then it sounds like your color channels were black instead of white
