Vray Water Texture settings & what they do-
"Height multiplier" is equivalent to "Wave Height" in HOT;
"Resolution" in HOT is specified with the power of 2, but is the same in both;
"Patch size" is similar to the "Size" attribute, but you should modify the Repeat U/V of the placement node to get the same effect;
"Choppy multiplier" - controls the choppiness, should be the same as HOT's "Choppiness" (the values are different, thought);
"Rate" - controls the speed of the animation;
"Seed" - seed for the random generator. VRayWater and HOT use different generators, so you can't expect to have exactly the same results;
"Wind direction" waves perpendicular to the direction (relative to the UV space) are removed;
"Wind magnitude" - "Wind speed" in HOT;
"Wind direction multiplier" - controls the effect of the wind direction. The values are from 0.0 to 1.0 (0.0 means direction is ignored);

"Patch size" advantage versus "Repeat U/V": avoids "repetitive tiling" look. E.g. start with a small plane, and default patch size. Make plane 4x larger, see is too stretched out. So try Repeat U/V to (4, 4). See detail is good size, but obviously repeated tiling. Reset Repeat U/V to (1, 1), increase Patch size to 4x larger number. Now good detail, without repetitive look.
ReplyDeleteThanks so much for that info Steve!
