Displace volume along normal?

[JonW]

First, I'm new to houdini.

I'm a fairly advanced nuke user though (if that is relevant)

 

Second, I'm trying to do the cmiVFX - Houdini Fractals Clouds and Terrains tutorial, but it seems that quite a lot have changed with Houdini since that was made.

 

In chapter 7 of the tutorial, you are supposed to render out an i3d file of a text. But, that node seems to be disabled in Houdini 15.

 

From what I've come to understand, the i3d-workflow has been replaced by regular bgeo files, which I assume is for a good reason. However, the tutorial uses Texture3d and gradient 3d, which seems to require an i3d file.

It seems that the Texture3d-node has been replaced with volume sample, and I assume that gradient3d has been replaced with volumegradient, however, I can't seem to replicate the result in the tutorial.

I think it's because the volume gradient node is sligtly different, then gradient3d.

 

Now, as I said, I'm sure that i3d is gone, for a good reason, and I don't feel the need to do it exactly the same way as in the tutorial, so how else can I displace the volume along the objects normal?

Welcome,

there are couple of ways of doing it. Check attached file for some of them. It is similar technique that Cloud noise digital asset uses. When you multiply displacement amount by noise you can then create cloudy look.

Thank you!

I will check it out.
