Hi folks,

I feel sure this must be possible in Houdini, but i have no idea how to do it:

You take a flat 2D image containing noise (or anything else for that matter) and use it to deform points, edges or primitives.



For example, say i have a 2D grid ……… i want to use the luminosity of a noise map to adjust the height of the points in the grid.

If anyone could give any pointers about what nodes one might need, i'd be very grateful!

Attribute VOP.

you can do pretty much anything with a node graph inside.

Many thanks for taking the time, JSMACK, i'm gonna examine your .hip!

I checked your .hip, very useful for me, thanks!

A question:

Is it possible to create an “image” in a copnet (with masks, gradients, color, whatever), then somehow bring that into an attribvop to effect stuff?

I mean in real time……..so, you change something in the composite view, and you see it also updating in the scene view.

I feel sure it must be possible, but have no clue as how to achieve it (route what to where?)

Yes, for the texture path use an op reference.
i.e.

Thanks but i really don't understand!

I don't understand the “COMP” part.

And also i don't understand how to change the texture path (in which node?).

Any chance you could change your original .hip to show it? Then i'll understand.

Sorry dude, i'm a beginner, i've only been messing with VFX for a couple of months!

Even easier…
In your geometry node drop a cop2net, dive inside and do your comp in there. This node generates by default an attributed mesh, with your image as @Cd, @Alpha yb default.

Ok, cool gonna give that a try, thanks!
