Re: Problem with Displacement filter!!!
I use these frequently, but I only have the 2nd edition, so I cannot comment on this particular case. However, I would mention that the key is to produce the mapping image at exactly the same size as the image to be mapped. This can be achieved in a number of ways, but Image / Duplicate will ensure everything is ok. It is also important to save the target file as a PSD and ensure the contrast is right. I would suggest examining the channels to find the one with the best and then adjust accordingly. I will get this book!! Nick |

Try changing Edit/Preferences/File Handling/Maximise PSD and PSB File Compatability from 'Never' to 'Always', that should do the trick. rufus |

Rufus, Please can you explain what the change of that setting is and how it affects the operation of the diplacement filter. |

Problem with Displacement filter!!!
Hi Big Vern, I had this problem a while back and I solved it by combining two unrelated bits of information. First the displacement filter uses a displacement map psd file, consisting of a composite background layer. There is no mention of this in the displacement filter help but it can be created by flattening the image. Second the "maximise compatibility" setting saves a composite background layer along with the other layers (so that older Photoshop programs can see the image properly). Setting "maximise compatibility" to always, solves the problem automatically. The only downside is the larger file size required. Alternatively you can just flatten your displacement map. rufus |

You only show up here occasionally these days, Rufus, but you're always a big help when you do. Thanks for explaining this one! Steve |

Re: Problem with Displacement filter!!!
So does the displacement map have to be the same size or does it not matter as long as it's a flattened psd file? |

Ellen, I would suggest it is preferable and I've always used them on that basis. However, the more proficient around here may have other views. Nick |

Re: Problem with Displacement filter!!!
It doesn't have to be the same size by any means. But for the two examples in the book, where a flag is mapped onto a piece of silk and a wall, having it the same size means the displacement precisely matches the size of the silk and the wall. If you're not mapping onto a photographic surface, then you can use any size displacement map - and set in the dialog whether it's tiled or stretched to fit. |
