View 2 RepliesI'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 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.
I extract a displacement map from Mudbox 2012 that has just a simple sphere. Then in Maya 2012, I create a file node and try to load the displacement map. Maya crash.....

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."
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'm trying to extract a vector displacement map out of three objects.
All three of them are on the same UV tile, with no overlap between each other.
All three of them have the same subdivision level and share the same Mudbox material.
I choose "Generate one map for all targets".
When hitting extract, Mudbox tells me that :
"Subdivision based map extraction is available only when the number of source and target meshes are the same".
Well its the case. With the same order in target and source models (A-B-C)
how to control the AO map, I want to extract?
I have a character that gets so much shadows from the own body (under chin, under arms, betweens legs) and I want to restrict this with a shorter ray, so AO calculation stops "behind the wrinkles", understand?
But no matter what search distance I set, what mode I use, I always get the same useless result.
Is it possible to selectively extract(apply disp to a mesh) tiles ala cyslice? If not...it would be very useful to have.
In my new little experience with other use of mudbox other that sculpting I still find it somewhat limited compared to cyslice. Also the extraction progress UI is quite buggy to me (at least it looks like it on my machine) as it doesnt update the status...and therefore you would think that the extraction process isnt working, but then, checking the directiory where the files are supposed to be saved, MB is actually doing the job.
And about the transfer detail to a new topology, is it possible to do it selectively? I ve tried to freeze, hide, areas that I dont want to transfer the detail to but nothing..still the whole thing gets transferred.
Just apply a new material, this doesn't work at all as it is always a ptex material. Trying to do an unwrap doesn't work as it says it is a ptex model. I can't save or load textures on the model as it is now a ptex material.
How am I supposed to remove ptex from this model? Mud 2012 obviously.
I’m using mud box 2013 and maya 2013, I’m trying to send a model/mesh through from maya to mud box by clicking the mesh and then file > send to mud box > send as new scene. This seems to work fine I get a little connected to mud box dialogue box in the bottom right corner and mud box begins to open, when it finally opens the scene inside of mud box is empty. Its as if its imported nothing.

I have Mudbox 2009 and am contemplating downloading the 2012 demo to see if Ptex painting makes things easier for me, but it won't work if I can't then bring the painted model into Octane or into my license of Max 2011.
What level is it advisable to pose a model. Coz revently I posed at a high mesh level(level 6 subdivision) only to find out that there was a lot of distortion in the arms when i actually brought the model to a lower level after the posing.

View 5 Replies View RelatedAs usual, i scaled my base model 10 times before importing in Mudbox for sculpting.But, when i reached about 10 mil polys (level 6) and started adding high freq details, i noticed that stamps have no effect on the model.It's like i never activated them.This happens with all the default and custom stamps i have.I get only the effect of the brush without the stamp.
Only knife brush seem to work and also its stamp works with other brushes as well.On the other hand, stencils work fine and as expected.
I'm having a problem with the transform of my model every time I import/export through maya and mudbox.
Basically every time I import a mesh from maya into mudbox then export to maya and back my mesh is shown smaller on the grid, I've done everything I can think of in Maya before exporting by centering the pivot, freezing transform, and deleting all history, but I still get the same result and my mesh just gets smaller and smaller?? I've also tried resizing it as well and get the same result.
I'm using maya 6.5 and mudbox 2011.

effects from a displacement map?
i.e. what should be contained in it for good effects?
trouble with displacement mapping. I am trying to cover a very rugged cliff face with the Union jack (british flag). I am trying to get a sort of old faded spray painted on look, following the rock contours.

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.

View 5 Replies View RelatedI'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.
