Octane well understand cinema noise and i see smooth noise gradients, but when i try to use cinema ramp octane get just half of container of generator without any gradient.
Octane does not understand cinema gradient shader in vdb generator texture slot? Is any chance to get smooth ramp volume?
it should do that but play with intensity of gradient colors.
Yes, of course I tried changing colors. Have you tried it yourself? It seems to me that no.
As you can see, (please take a look at attached image - first column) at any value of the first color of the gradient, we will not get a smooth fading of the density.
And if i invert points of gradient, octane will interpret density another way (why?). When we reverse the colors of ramp, we expect the effect as if we rotated the volume box 180 degrees on the Y axis.
And even so, all the same, we will not get a smooth fading of the density from 100% to 0%.
Right-bottom image shows a smooth gradient of density, but this is not the correct result, because there should be 100% density in the left corner of the volume box.
Maybe you could fix this issue?
