Mudbox :: How To Export Ptex Paint Layer To Be Used In Another Application
Feb 25, 2012
I'm having a problem trying to export a ptex paint layer to be used in another application.
For some reason when I export it, everything seems to work just fine, until get gets to calculating tangents and then it hangs forever on 99%... Every way I try saving the file, it does this. I can easily paint on my mesh, and save the project file, but I can't export the ptex file.
Deleting the mydocuments/mudbox folder which I did.
I'm using mudbox 2012 64bit on Win 7.

If I don't set up UVs in my model and instead use PTex painting in Mudbox, can I then export the model to OBJ with UVW maps? I would like to import the model to Octane render which imports OBJ files and their UVW mapping.
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.

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 working with Maya 2013 and Mudbox 2013, and try to use PTEX painting in order to paint my character.
Anyway, for some reason, I'm getting visible coloring seams and distortion along them when trying to color with a stencil/stamp over some regions on the model.
Usually, texture gets distorted around extruded regions on my model, and if that's the case - the whole benefit of painting seamless texture goes out of the window.
I tried increasing/decreasing PTEX resolution, also searched in this forum and tried also edge bleed reduction/increase - unsuccessfully in all. Seams are very visible and texture is distorted.
Now, maybe it's something that is related to the natural bounds of the PTEX technology, but maybe it's just some obvious solution I'm just completely missing.
My work process is importing models from Maya by using Send To Mudbox option, then setting up PTEX with the proper resolution and starting to work.

When I setup a model for ptex painting in mudbox, it's not properly using the surface derivatives of the mesh's faces. Thus the faces which are really small are getting the same size texel data as big ones. This obviously is bad because anything with small bevels and hard surface type work becomes incredibly problematic.

i have an obj with a layer in multiple channel, and when im increasing the ptex setup locally in some area, it seems to create artifacts in the Normalmap Channel. It looks like the mapping is broken only in this channel.

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."

It try bring an image into paint layer. I found that there is this function:
PaintLayerImporter() and it takes 4 parameters. They are:
1) const QString &sFileName, ///< Name of the file to import
2) int iFileTypeIndex, < Index of the type of the file in the array returned by SupportedExtensions
3) Mesh *pMesh, ///< Mesh which contains the paint layer
4) TexturePool *pTarget ///< Destination of the import operation
But I'm not able to get this function to work. Any small example how to use it.
I think that main problem for me is that I don't know exactly what 2) parameter means(int iFileTypeIndex). It says that you get that from SupportedExtensions but When I look at it:
virtual QVector<FileExtension> SupportedExtensions( void );
It surely dosen't look int.

I set up some selection sets thinking they would come in handy later on when I am painting. I thought I would be able to use them to paint my layer masks, but I cant figure out a way of using the selection to limit where I am painting inside the mask. I thought convert to a freeze but it seems paint layers ignore frozen areas. Is it possible, or is it a case of saving selections for sculpt and not for paitning?

Any successful script for X4 that will export each layer individually as a .png? For instance: I have 10 layers, each having one element, I need each element to be exported into it's own .png file for future manipulations and althought I've tried writing my own, I was unable to get it to work

Any way to export mudbox displacement maps so that 50% grey is seen as zero and black and white are equal and opposite values of displacement? Currently if I render an object in Maya with a mudbox displacement map I get the entire surface pushed out instead of just the high points. My work mates that are using Zbrush tell me that they don't get this problem.

how to lay UVs for seperate objects into tiles so that when painting in Mudbox I can color each object without the color bleeding through UVs to other objects.
I tried resizing them within the UV space but this didn't work because I also need them to have a high resolution so I can get detail in Mudbox...
I basically want my UVS to look like they do in this picture...

I have a character model in Mudbox 2014. I exported the face, body and hands as individual .obj files, each at its maximum subdivision level. But in Mudbox 2013 the sculpting layers are all flattened on the main layer.
Is there an option to keep the sculpting and painting layers intact?

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.

Am I missing something very basic?? I am trying to invert a mask on a sculpt layer. I don't seem to be able to invert a mask on a sculpt layer.
I have a layer with sculpting on it an I need to separate it out into two different layers. I painted a mask for the parts that I want to mask out and then duplicated the layer. Now I want to invert the mask to reveal the masked out sculpting on the second layer but I don't see the "invert mask" function that I thought for sure was there. I see invert freeze but not invert mask.

I am painting a brick wall, the wall is separated into 2 objects, the bricks and the stuff between the bricks.
The problem I am having is that I isolate the stuff between the bricks and paint that gray but when I "show all objects" the gray color have transferred to the edges of the bricks. I have tried maps with different resolutions but that makes no difference.
How do I make it so that I can paint only on the isolated object?
One other way:I can apply 2 different mudbox materials, 1 to each object and create 2 diffuse maps, 2 bump maps and 2 specular maps. But how do I combine the different map with each other?
The objects are going to be combined into 1 mesh that uses 1 diffuse map, 1 normal map and 1 specular map.

Is there an easy way to paint weights across multiple objects? if I have a body + shirt + armor and want to create a joint and similar weights on all currently I found a very awkward way to do it which is do it on 1 object and manually try and paint weights in a similar way on all others.

I'm trying to create a custom stamp in Photoshop. Done it with a 16 bits colorspace, saved as TIFF with the required options from the official documentation.
Why do i get a 'grainy' result, even painting with a 100% strength white color ? It happens only on a bump layer. On a diffuse layer, its ok.
Do the bump layer use a 8bits color space ???

I have painted my base mesh with PTex using Mudbox. I have made some changes to the original mesh. Now I wanna transfer paint layers from my old geometry to the new one. I imported the old geometry with PTex paint on it. Then I imported the new modified geometry. But When I try to set it up for PTex painting, Mudbox crashes. This happens when setting the resolution. Looking at the log, the error seems to be "Segmentation Fault (Core dumped)".

I am using Photoshop CS6 and if I have nested layer groups whose depth is greater than 5 I get the following error message. "This document contains nested layer groups that may change in appearance if opened in applications older than Photoshop CS6".
I can click on "don't show this message again" before pressing ok, but can i disable it from showing somewhere in the application settings? I want to enable it sometimes and sometimes not.
- The "Reset All Warning Dialogs" button from Edit - Preferences - General is not very usefull because I want to keep other messages' settings, only this one should be affected.

What I want to do is to have an adjustment layer that is a reversed, black and white image. I initially thought to merge B&W and reverse adjustment layers, but read that an adjustment layer may not be the target of a merge. Is the way to accomplish this to fiddle with the B&W adjustment layer sliders somehow?
I like how the black and white displayed image of a given color channel looks, how can I export that channel into a layer?

I just recently started having problems with my PSP Photo XI program on my laptop. The other day it would start up and run normally, but the next day when I went to run the program, it wouldn't start. My computer would freeze up and show this error message: "The application failed to initialize properly (0xc0000006). Click OK to terminate the applicaion."
I tried turning off my computer and running the program again, but the same thing came up. I tried to run the repair program on it, nothing. I even tried to uninstall PSP XI to no avail as I got a different error message: "Internal Error 2328 C:Program FilesCorelCorel Paint Shop Pro XICoreErrorCodesRC.dll"
I really don't know what to do, short of just completely resetting my laptop back to factory settings and starting fresh. But even then I don't know if that would fix the problem.
I wish I knew why the program decided to just stop working one day, as I haven't downloaded anything and my anti-virus is up to date.My computer is a Dell XPS M1710, and it runs Windows XP SP3.
