I pick up butter melting corn for my project. I decide to procedurally model the corn inside Houdini, and I had run into a problem with the corn kernels arrangement and here's how I fix it.

I was using scatteralign node and copy to points but the normal is not correct. So I use the normal and up vector inside point wrangle.

I also have issue with assign the random color for each kernels. I pack them inside the copy to points in order to solve the problem.

I have to figure out how to use karma shader override for the corn and also use the ramp inside point wrangle node to control the shader of the butter. The butter will have two colors because it's melting; one color is transparent, and one color is dark yellow.

I did change the color randomly by using point wrangle node for corn kernels. I can also get the butter transparent base on its speed and heigh, the speed is based on velocity, but the issue is when the butter drip on to the ground, the color appears.

When it comes down to the second material in karma, both corn and butter's material become strange. I don't think my material override was successful, I'll figure it out.

I try to use assign material to do the material override, but it didn't work. I think it's either the override Vexpression or material path problem.
