simple material mix question

[naik3d]

Hey guys

actually this one should be very easy but i can't get it to work.

Imagine you got a lng cylinder with a texture on it ( from the bottom to the top)
Now i add another diffuse material ( bright red ) and also
a gradient texture and a mix material in order to combine them all together.

So i want the ( black / white gradient) to controll where on the cylinder
the color should come through and where the texture should be
visible, actually very simple but it doesn't work.

The Mix Material always mixes the whole object, but what i want
is to see ONLY the texture at the bottom to the mid point of the cylinder
and then with a smooth transition to the top only the texutre.

Can anyone give an advice?

The nodes seems ok, so its your uv map (scale?) that is wrong / not exact as you want the mapping to happen.

hey mate,

That's unlikely because the texture which lies on tha cylinder fits perfect
( Some kind of a logo)

But maybe i can check it again.

hey guys

i just can't get it to work properly...
Can someone give me a hint?

Maybe just a test scene with a cylinder and two diffuse materials ( just the color )
and the mix material with a gradien texture ( inside octane --> B/W)

cheers

really no one???

[matej]

What kind of node is that "gradient texture"? Is this the new version? If it's a procedural, check it's scale (default procedurals scale is very small).

[naik3d]

There is no parameters called scale in the gradient texture.
I think this gradient texture is not what it is meant to be.

So ridiculous, that such a simple task gets so complicated!

p.s it seems to work somehow with the sine wave and saw wave texture.

Can it be that the gradient texture needs a real texture ( jpg etc ) as an input to work?

Just use a float image with gradient made in Photoshop...

maybe just a simple thing: maybe its just the wrong size or aspect ratio of the image.
there is just one uv-mapping for the object, so the texture which controls your mixed material amount in this case your gradient tex (image) must have at least the same aspect ratio as the one which is mapped in 3dmax onto your cylinder.


edit: oh, now i read it above, you got it already solved. thought you already used an image for your gradient..
