Mudbox :: Baking Displacement Map
May 7, 2012
I modeled a female body and imported from 3DSMAX to mudbox to texture but now i'm having trouble on baking the displacement map in MUDBOX. I'm using tiff 32 bit floating,7 x 7k, with search distance of 4 (i believe it's a relative good number). My source model is step 0(with about 2 million faces) and the other is step 2(with aprox. 6 million faces). I'm using target to closest model, smoothing only the source and wht i get is this: a big black image with one or another gray dot.
I saw several tutorials about wht might be. I changed several times the search distance, and also tried to bake in max. Nothing seems to work. Mudbox keeps leving me with a blck image and max gives me something strange that works a little as a displacement map but it is totaly untileble.The two images attached are from mudbox. One as i get, and in the other i tried messing with levels in photoshop but it didn't work too.

We're experiencing some artefacts near UV seams on our baked displacement maps. We have a clean, multiple UV-tile model which is subdivided, sculpted etc. Baking uses subdivision method, smooth target mesh and UVs on (we render with prman). Edge bleed is default 2, anti aliasing to x2.
Then test the map out by bringing the target model back in, subdivide up to the corresponding level, and sculpt using maps. The artefacts are not everywhere, just on some UV boundaries in some areas, very strange. The UV boundaries are clean quads, same spacing, good use of UV space. My concern is its in sporadic regions, and not globally over all seams.

I get an error both in Mudbox 2013.sp3 and 2013.sp2 when baking using subdivision method. Its reported ' too many extraordinary vertices found face , need to subdivide the mesh' and the extraction failed.
The model imported fine into Mudbox in the first place, Is there a particular count for extraordinary vertices ?
As far as I know, extraordinary vertices are as follows
Valency 3 : 3 faces connected at a single vertex
Valency 5 : 5 faces connected at a single vertex
Valenecy 5 or higher : lots of faces connected at a single vertex (top of maya sphere)
Most meshs contain valency 3 or 5, and mostly 4, why would mud box have issues with a model like this ?
Should I check for areas where there's lots of density of faces at a single vertex, or check for multiple extraordinary vertices that are close by ? Anything in UV spa

I'm sculpting a portrait work and after generating the displacement map, the map itself automatically is displayed in the model. This is actually the second time I'm experienced this.
How can I disable this auto function without having to turn off the layer in the layer tab each and everytime mudbox generates the displacement map.

I thought I had this all working. And it did to an extent. When I plug a single displacement map into my standard lambert shader slot in maya, all works fine and dandy. However, as soon as I try to use multiple displacement maps, I am getting the problem that I had in the previous post, which is that the negative values are lost. I sort of understand why this is happening - that is when using a layered shader it uses alpha as luminance, and therefore the values don't go below zero, but I don't know what to do about it!? I have tried a network with set range etc but it just makes a mess. Any straightforward method of using multiple .exr files in a single shader for mental ray in maya?

Can a PTEX vector displacement map be used as a stencil or stamp? If not, what's the workflow for going from a PTEX sculpt to a vector displacement texture (e.g. TIFF) that can be used as a stencil / sculpt.
The problem I'm experiencing is that I sculpted a plane with PTEX and exported a PTEX vector displacement map, however, when I go to the Image Browser to attempt to use it as a stencil or stamp the PTEX file does not show up. The only files I can see in the browser are TIFF, PNG, etc. If I change the Output Options > Map Type to from PTEX to Texture I get an error: "At least on target model has been set up for PTEX. You must select PTEX format(*.ptx) for maps extracted using this target."

Any good 3d party texture baker. They bake hi-res things forever and neigther can bake complex procedural shaders and details with transparency properly.
Is there any 3d party render that could be considered for texture baking? I tried Vray but it's even slower in baking. Is there anything other to try? I mean something with a speed of Modo texture baking for example?
Looking for uick render settings for texture baking? Mental rey or scanline. Prerhaps I should degerade or avoid something not tailored for texture baking. What would be a prefered way for indirect illumination or ambient occlusion? Is there a renderer that would respect edited vertex normals on low poly shells while doing baking?

When i press play on physx toolbar everything is simulating fine, from start to end.Problem is when i want to bake physics simulation to keyframes.
3dsmax freezes and whole process is taking a lot of time, about 8 hours.
Simulation without baking is taking only 20min.
3dsmax file before baking process have 20MB and file after baking have 9GB
Is there other, more efficient way to bake physics dynamics or to simulate physics Maybe using particles with physics? particle toolbox #2 ?

I have 20+ layers that all need the same levels adjustment, so I put them in a group, and applied a Levels Adjustment Layer to the group.
Is there a way to bake that adjustment in to every individual layer, while retaining them as separate layers?

I'm working to Move Revit architectural files to 3ds Max, there use Vray for ligting and materials, texturebaking everything and moving it into unity. But I’ve run into allot of problems. I manage to get all the stages done, but there is so much “hands on fixing” that it’s not a viable workflow in RL projects.
My largest problem is removing all unwanted polygons and geometry before texturebaking. From revit you get a lot of faces that won’t ever be seen, like inside walls, in between there floors ect. For instance if I was doing an interior I would like to be able to quickly remove all unseen polygons and exterior faces that won’t be seen. Otherwise texturebaking is a pain. It will texturebake huge areas that won’t ever be seen making the process long and affecting resolution. Manualy removing all areas that won’t be seen is not an option.

If there is a similar function to "Execute function and repeat" in order to make the displacement of various objects. For example I have 5 different objects and wanted to give them a displacement of 1.5 cm, how to do this automatically by Corel Draw ?

trouble applying a displacement filter to my flattened images. I think i know how to create the displacement map. I right click on any one colour channel; duplicate it; save as a new channel; and save this new b&w image as my disp. map.
But then i go back to the image that i want 'displaced', click on the appropriate layer, go to Filter>Distort>Displace, click OK on the little dialog box and then open the previously created disp. map. Then nothing happens.
i have CS3 Production Premium installed.

I'm trying to use either the displacement or 3D rendering function in Photoshop CS to make a realistic looking tattoo on a face, but I can't get "distort" or "render" to come out of grey no matter what I do.

I've tried to flatten a drawing using the displacement method (selecting all, then moving by displacing 0,0,1e99 and then displacing back).
Somehow I didn't select all objects and now some are on z=0 while others are not. Worse yet, I didn't notice it in time, so now some objects (dimensions, lines, etc.) have one end on z=0 and another on 1e99/-1e99.
Is there another way to make all objects have z=0? Best if I can be sure I select *all* objects (currently ctrl-A tells me some objects are on locked layers, though I can see no locked layer and some are not in current space, whatever that means).

Filter > Distort > Displace is undervalued gem, yet it has significant drawback - the displacement does not interpolate between adjustment pixels. This shortcoming in combination with the fact that Photoshop uses very fine noise to smooth transitions between gradations in 8-bit channels and therefore creates very unsightly, jugged effect even when displacement source is a gradient. Unfortunately the filter does not work with 16-bit channels and its closest relative - Liquify uses meshes instead of images for input.
So here is my question: does any of you aware of a way, in Photoshop or otherwise to create silky smooth displacements within 2D imagery (there are bunch of software to accomplish it in 3D) using interpolated 8 bit or original 16-bit (or higher) images as source?
The attached image was produced by displacing perfectly smooth word "test" with plain black to white gradient at 999% displacement strength.

is there a way to create smooth displacements using images as map. Since displace filter has only 256 levels it consistently creates jaggy results when used with settings of 100% and above. So this filter works reasonably well for small displacements and small images, but try to displace group of pixels 500% in 10 by 10 inch file at 300 dpi even using silky smooth gradient. Desired effects can be achieved to some extent with liquify filter, but that filter in turn lacks ability to use images as maps. I hoped that 16-bit support in CS would extend to displace filter giving us 64000 levels insted of 256, but this is not the case. Gradients themselves can be very smooth now, but displace filter will not accept 16 bit files.

I'm sure I linked from it here but can't find the one particular tutorial again. It showed how to conform text on a human face using displacement maps and was a particularly good tute. Someone I know needs that exact effect and I can't find the tute again. I've done considerable searching but can't find the link again.

What I am looking for is some sort of plugin that takes the tediousness out of it and lets you preview it in realtime.
An ideal plugin would be able to do the following:
-view the source image - image to be displaced.
- View composite image preview(what you see in photoshop when the disp map is applied)
- View Displacement Map preview - hopefully these would be side-by side
I have an image of a face, and an image of text and I want that text to look like it is wrapped onto the face.
Select the face image (ctrl-A) & open the plugin. THis becomes the composite (preview) image
Next to that is the Disp. map. In this case I would check a box that says "use composite as displacement map" It would greyscale the image of the face, and that would be the height/depth disp. map whihc I could then fine tune.
Next to that would be where the image to be displaced is. I open up the image file of the text.
Now I see in the "Composite image" the text wrapped around the face, following the contours of the face. I can adjust the levels of the disp map to create a more dramatic or more subtle effect. WHen I'm finished I click OK.
The "file to be displaced" (in this case, the text image) can also be "same as composite"
If you have ever seen this image where it looks like a photo of a crowd taken from above, but it almost looks liek the height of the people forms Bill Clintons face, this is what this would be used for.
The composite would be the photo of the crowd. The disp map is the photo of clinton's face. SInce the displaced image and the Composite image are the same (via checkbox), you just hit apply after adjusting your disp map. It applies the disp map to the selected original image, and the lights & darks displace the original and give it that look that I just described.
- click to open a source file for the disp. map. - ideally I would be able to open even a color jpg, and it would convert it to greyscale upon opening in the plugin window.
- ability to use the selection (preview composite image) as a displacement map rather than saving & opening it up
- invert the greyscale disp map.
- ability to adjust levels of the alpha/disp map in the preview window in order to darken the darks, etc.
- ability to resize/rescale the dispmap in the preview window. THen in realtime or close to realtime I would see the results in the Source Image preivew window. This way I can shrink or grow the disp map to fit my selection if need be
- Ability to grab the disp map and move it around in order to precisely line it up against the preview image
