Thanks, that point cloud check box really speeds things up. BUT, big BUT, it makes the water behave very strangely, I tried a lot of combinations with parameters to no avail. I went up to 10 million photons in 1 test. I also tried the classic and the principled shader instead of the basic liquid. Please watch the attached attempts.

The walls are in the geometry “walls” node, also there is a front wall set to phantom “box_coll” , it's just a scaled box.

Hi, as mentioned above, there are no walls in your scene, the ‘walls’ object node only has the floor/ceiling geometry.

There is also a reference to an alembic object with a path do your local machine. Could you repackage the scene with the necessary geometry and file references.

Cheers,

Hey there guys.

Now what Houdini is starting to move away from using local variables, I am lost in how to achieve certain results.

So back in the old days( I still do it due to the old point node being available ), I would use the old point node, plug a point into input 1 and then another point into input 2. Then I would add a normal, and set the X to $TX2 - $TX, the Y to $TY2 - $TY, and $TZ2 - $TZ.

Now that Sidefx is pushing for vex ( which is a good idea to keep Houdini more focused and allow us to have faster executing networks), the old point node would now set the normal to @N.x, @N.y, @N.z instead of $NX, $NY and $NZ

So my question is….

How would I convert $TX2 - $TX into vex to set the normal direction like I used to?

In the new Point Sop ( Attribute expression sop ), set the ‘attribute’ parameter to N and then in the VEXpression field enter :

v@opinput1_P - v@P

You can use the “opinput_” to fetch attributes from other inputs. This works in wrangles, etc.

Hello,

Copy stamping will work, but is unnecessary in this case. It will also make your network much slower, since each copy needs to be evaluated individually.

Using N or Orient, you can align your copies along the curve, and use attribute randomize to adjust the copies. There are, of course, many ways to achieve this. This is just a simply way.
