I got Hot4d to work with S24 (I assume the tutorial also works for 25 and 26, but I can send anyone my working plugin if they want), and I am trying to get a good water material.
Does anyone have good tips?
I am using only reflection and subsurface and bump right now. I know it can look better.
I am also unsure exactly how the subsurface values work. Are the weights of each layer combined to total 1 or can each weight also be 1?
And I am not sure what the radius means for each layer.
Does anyone have good material for water? (hot4d)
Why do you use subsurface for water? It's more needed for organic surfaces like skin, wax, cheese or fruits/vegetables. The radiuses of SSS layers tell how deep the light can enter under the surface with certain color and weight. The colors and weights of layers are renormalized if you use large values of weights (in case their sum exceed 1).
But returning to water you should use reflection + refraction with the same IOR, e.g. IOR = 1.4. Also for sea water you can use Absorption layer of material where you can make some dark blue color of absorption and a radius that tells at what distance the light will turn to absorption color. Just make experiments.
Also it can be possible to combine with translucent + absorption layer potentially using mix material with another material that holds this just to make the peaks of waves with some white effect for foam.
But where is absorption layer in centileo?
Are you referring to absorption in the transmission channel?
I also tried using transmission set to 0.3
but you suggest translucent instead?
This is my new attempt. The second image is with the normal map scaled down to 0.1
What do you mean radius changes? Which channel? I thought only subsurface has radius. Unless you mean the distance scale?
I had turned off subsurface and just used transmission absorption to get the blue colour.
When I reduce the HSV v value I get the grey look. But if I reduce the h value I get this nice light blue near the rocks.
I also just turned on ls liquid (not in these screenshots). That helps for materials for liquids?
Which value is 0.9-0.98?
I tried using diffuse again instead of transmission absorption for colour, and I kind of like it better now. And my normal map reduced scale I think gives more detail in the third image.
Also I assume that you are using the second reflection for foam effect. Try adding the same bump map filtered through a gradient texture to the second reflection weight. Adjusting the gradient slot you can get better foam.
foam created using noise texture(same as bump map)
same setup wide angle
adjusted the foam effect by gradient
Thanks for the tips. I will try some of them.
I haven't tried foam yet, but there is a 5 part tutorial for hot4d where he shows how to use thinking particles (or some other particle) and pyrocluster to make foam.
do you use Ls liquid?
Maybe if I try more noise detail it will help, but it didn't make it look better when I enabled it before.
