I am trying to use the displace filter, with a texture/displacement map that I made. I have it saved as a .psd file, and it won't work. I can use the ones that came with the program, but not ones I make. I sent my texture to a friend with cs2 (as a jpeg file), and they saved it as a .psd file for me, and it works. So I'm wondering why I can't make my own, save them and have them work for me?
View 2 RepliesTitle reflects what i think i need to use. What i want to do is bend an image to fit within the line drawing below see images attached.
i know it can be done many othre ways but im only interseted here in getting to grips with the displace filter so once i get to grips with the basics i can apply it to much more colpex shapes i.e mapping an image onto a folded dress.. I know i use a gradiated B+W psd. but im not sure what values i need to insert..
In my work I am using Displace (Filter>distort>displace) filter to create fake parallax shift, to create stereograms. I make two copies of image- one using positive-value horizontal displace filter, the other negative. When viewing those images as stereoscopy pair, you perceive them as projected on 3D surface defined by grayscale displacement map (a.k.a. depth-map).
My problem is highly specific: I need to be able to precisely control which pixels are displaced and by what ammount (ammount defined by greyscale value of map pixels). Current implementation of displace filter makes if very difficult.
My goal is this: every pixel of image will be shifted left or right by distance defined by greyscale value of directly underlying depth-map pixel.
The way actual displacement filter works can be described as such: If depth-map pixel is <50%grey, it 'fetches' and becomes bitmap pixel from left. If depth-map pixel is >50%grey, it 'fetches' and becomes bitmap pixel from right.As a result-I cannot, by comparing image pixels with underlying depth-map pixels predict what distance will given image pixel travel. Shift distance is not defined by directly underlying dept-map pixel. Instead, image pixel is 'fetched' by undefined depth-map pixel.
I realise it is highly specific requirement without an easy answer. I am willing to spend long time working on software side if need be and learn in process. I am becoming quite proficient in scripting (JavaScript). I need to know where to start and if there is a solution simpler than coding new filter from scratch.I am using Photoshop CS6 and work cross-platform (primarily windows).
where the upshot of the post is that the filter isn't working because the the map wasn't saved with compatibility turned on.
The 2nd person to reply, Terri Foster, said "maybe the map is buried too deep in your file structure" - she is absoultely right.
I spent 2 days reinstalling Photoshop (CS2) and trying to get the effect I wanted without the displacement filter. My file was buried 8 folders deep and I tend to use square brackets in folder names, too. Once I'd saved the map to the desktop instead,
I am trying to map hundreds of fabric pattern to a window curtain for catalog purpose. So I am thinking to shoot the displace map with white fabric so that the displace map will clearly distinguish between the black, gray and white.
Then I took a step further, I am thinking to use a green fabric with red border on the bottom of the curtain so that I can tell photoshop to map pattern A with green and pattern B with red.
However, I am concern that since green and red panel with shadow and highlight isn't exactly the same as white fabric with shadow and highlight; therefore, the displacement of the fabric pattern will be different between white background and colored background.
How do I solve this? Is there any way to tell photoshop to convert colored fabric to a "white" fabric with all the shadow and highlight accurately represent?
When I go to open the displace filter it just crashes .

View 3 Replies View Relatedso I made a displacement gradient map, flat image, I saved it as .psd file, with ICC deselected, then I opened desired image, a jpeg one, I choose filter-distort-displace, I enter 100 horizontal, 0 vertical, strech to fit and repeat edge pixels, ok, select the newly saved displacement gradient map.psd, ok and NOTHING!!!............no displacement, distortion, NOTHING!
what I did wrong? seems like nothing but I must have slipped something out of memory.
There seem to be some errors in the code for Modify > Convert > Displacement to Polygons with History. My scene uses an animated displacement map, coming from an image sequence. The displacement works as advertised, but I keep getting execution errors. Here is the code for the offending expression, which was created silently when I issued the conversion command:
if(!Disc1_MeshShapeDisplacement1.disableDisplacementUpdates){
updateAnimatedDisplacement( "Disc1_MeshShape","Disc1_MeshShapeDisplacement1","displacementShader1.displacement");
}
//Setting the following attribute here dirties the mesh so Mental Ray updates properly
Disc1_MeshShapeDisplacement1.featureDisplacement = 0;
//The next two lines cause the expression to trigger when editing attributes that affect the displacement
float $dummy = displacementShader1.displacement;
Disc1_MeshDisplacement1.inheritsTransform = true;
The only way I can stop the constant error messages is to comment out the code or disable expression evaluation.
The error messages are annoying, but I can live with that. The real problem comes when I try to select keyframes in the timeline. I shift-drag across keys to select them, and they highlight at first, but then the highlighting immediately goes away. I am forced to use the Dope Sheet instead. Disabling expressions doesn't work, so I don't know if this problem is related to the displacement expression or not.
Displacement in Maya has a very bad reputation, and based on my experience, it's well-deserved. Another issue I have is that after conversion with history, multiple shape and transform nodes are visible in the Outliner, and it is not clear what's going on. The documentation for this feature is only two lines long, and does not explain anything. Apparently there is a pre-displacement shape and a post-displacement shape in the scene, sort of like how nCloth has an input and output mesh. But with displacement w/ history, users get no guidance on how all of this is supposed to work.
I'm using Maya to render out a greyscale image TIFF 16bit for use in Mudbox as 'Sculpt Using displacement'. The background is set to 0.5 grey and rendered as TIFF 16 from Maya. However, when applied as a sculpt using 'displacement' in Mudbox, the mesh slightly inflates (or deflates actually) every so slightly.
Is the issue cuases by my mid grey from Maya , tiff format or something else ?
I am Using Mental ray (max 2010). I have made a topological displacement map at a very low resolution. it is 222 pixels wide by 111 pixels tall (landscape) It is greyscale and low rez because the mesh I am applying it to is 222 faces wide by 111 faces long. (landscape also). I did this because I needed each pixel to become a "height map" in its own right. Everything is working the way i expected.
My problem is.... I need to now make each face z planar. as it stands, they are all tilted in the direction of the grey scale falloff. I have tried splitting the edges of all the faces (quad) and using the make planar (z) function of edit poly mod. No matter how I set the pivot / ucs, when I apply the make planar z , they all average out to the same z plane. I need them to adopt the average of their individual z planes. I can do this but have to do it face by face. That's 24642 faces.
How can I make Displace modifier to use objects existing mapping? Because when I apply a new Displace, the modifier makes a new mapping, even if i check "Use Existing Mapping".
See what i mean? I want those "cracks" to follow uv not a displace mapping
I´d like to know how to move/displace multiple objects (in this case bricks) like it is done in this animation (at approx. 0:15 sec) [URL].I tried to reconstruct the effect using bigger bricks and tangent constraints, which worked kinda ok but I had to constrain every single brick manually which was rather time consuming and definitely not the approach they must have had used. Is there a way to achieve similar effect (pref. without scripting)?

I need to be able to horizontally displace an area of vertical stripes using a specific greyscale displacement map.

I tried to use the lens flare filter in Photoshop CS6.While the lighting effect is interesting, it introduces ugly artifacts like blue or orange blobs (which are supposed to be the reflection of the diaphragm, but do not look anywhere close to that, but instead are just cheesy looking blobs of color).
In the "movie prime" setting blue lines are added which have nothing to do with lens flar.On top of it, the preview is about the size of a stamp. Any way to use the filter without getting these artifacts, or is it - what I assume - just a useless toy filter, that has probably been dragged on for years and years because it's always been there? What do you use to create a lens flare effect? Are you just building it from scratch with brush work?

View 1 Replies View RelatedI've deleted my PS preferences and restarted, and I cannot get this filter to do what is was just doing a day earlier. It doesn't matter what the foreground/background colors are, nor does it matter what the resolution of the file is. I've experimented with every variable. The filter effect changes the filled layer to a solid color of the current foreground color. No lines, dots or circles at all.
I'm trying to make lines in a filled layer, or a rasterized text layer.Adjusting the sliders has no effect at this point, but the other Gallery filters DO work, oddly enough.
I've used this filter effect many times over the years, and it just started acting wonky. This is PS CS6, on Mac OSX 10.8.5.It seems to be unpredictable or temperamental. Is there a reasonably-priced plugin that will create lines that are completely adjustable?
I have Photoshop CS4 running on a 8 gig Vista 64 bit system. When I click on Filters, there is no Extract Filter. I did a search prior to posting and saw some threads talking about not moving files, icons etc from their original folder. I am un sure if anything has been moved. However, when I click on Filters, they all seem to be there (at least not greyed out), EXCEPT for the Extract filter. Any help would be apprecited and if you let me know where the filters should reside I can make sure they are in the correct location.
