we've used alpha from the new component in texture A. But
the preview window looks quite different : the whole
cylinder is dark again!
Never mind : we know what to do. We change the scale of our texture.
Click on the green button topleft of texture A to open the Transformation Tools window. Then put your mousearrow on the center of the top cube and drag to the right till you get about 60 percent. Exit with the check mark to enter the new settings.
The transition from light to dark is lower now, but the texture looks different.
we want to adjust only the transition, we'll have to get
into the DTE and the noise filter again.
you left the materials Lab , open it up again.
Open up the DTE for texture A and open the Filter Dialog for the second component.
You can open the Filter Dialog by clicking the pebble in the bottom of the DTE or the blue circle in the top righthand corner of the component.
on the graph itself ( left to right to adjust a , up - down
to adjust b ).
factor a is higher, the noise pattern will change more
quickly from black to white,
would be handier if you could enter a numerical here, so it
would be consistent with other settings in Bryce, but you
can't enter one (yet) : you'll have to drag.
the DTE with the check mark : the preview looks just like
it did when we used 2 textures and the second one scaled
we'll combine the two components differently to get that
'wet' look, as promised.
on the combination mode Average. A whole list of other
modes appears : select Procedural Blend.
What happens is that the alpha component ( Altitude filter, remember) in component 2 applies colour 1(black) at low altitude and colour 2 (gray) at high altitude.
Procedural Blend uses the graylevel of the colours in component 2 to apply the colour from component 1 to the combination.
Procedural Blend will also blend in the colours from component 2 into the combination. We set them to gray and black so the colour from component 1 would remain the same.
you find the 'wetter' part too saturated, change the top
colour from black to a lighter darkgray till you like it.
did we switch off Alpha ? Because we don't use it.
The Alpha information defines where colour 1 and colour 2 is applied in component 2, but it is not affecting the COMBINATION directly.
If you want to test this for yourself, change the luminosity of both colours to 128 : the colour in the COMBINATION will be equal to
