Wow! thanks! I will look into this and will be back with my new trial.

Hello everyone!

I am trying to make a digital asset which can generate a realistic wood grain texture.
For this, my first step was to make a irregular wave pattern which I can control with some parameters.
I thought I made it with the following codes:

f@leng = length(@P);
f@ang = acos(@P);
int seed = ch("seed");
f@deform = 1 + sin(@ang) * noise(@ang * seed);
@Cd = cos(@deform * @leng * $PI * chf("frequency"));




Then I found that my wave pattern is irregular but not perfectly irregular as they are symetrical to x axis.
I don't know what I did wrong.

Can anyone help me?

I have problem installing Renderman 24.3 on Houdini 19.0.455.
I tried both python2 and python3 versions and they both did not work.
I copied and pasted .json file as instructed by Renderman Installation Guide.
Anyone has a solution for this?

I have following error messages:
