Hi and thanks for reading this. For a Course project I need to find a way to realistically create a “peeling” effect. Somewhat similar to the peeling of paint of a wall. Or the peeling of wall paper.

If you have watched the film , Silent Hill, there is a very similar effect, of how the walls seem to just melt and peel away.

Currently I ve been experimenting with cloth dynamics with cloth stitch constraint and the effect seems ok. However I need to find a method to make many parts of the wall have pieces of paint/paper of different sizes all peeling in their own time.

Any suggestions, methods, procedures yadayadayada on how to carry this forward are more than welcome,

Thanks.

hi!
You could try the Spring SOP, it is fast, but i had problems trigger it with user created attribute, since this is an old SOP it won't accept any previously defined variable. But since i'm not that experienced maybe there is a way.

The first two videos here will show you how the spring sop works,

And here's a hip file that might help you with triggering animation with colour.

Thanks you so much, will definitely look into that.

by the way, I have attached one of the test renders of the cloth sim, with the peeling effect.if there Are there any Other ways to achieve something similar… i d love to know…

Link to the effect in the film.

It also looks as if the paint is turning to blood, this could be done with 2 texture maps one been blood and another the paint. All you would need to do is use a fractal noise to blend between them.

Ive done this in 3ds max but if someone knows how to link it up in houdini please say.

Also can a video file be used in houdini to be rendered out as a texture? as this would help the movement of the blood.

Ironic, the movie was done with Houdini, by C.O.R.E.

No on the video, you need to convert it to a sequence of images.
