ZBrush Usage Questions
#1

Hi,

This is a question regarding the file format for the 3d print.

Installed PrintingExporterDataWinV1.1 just now and things all fine. After exporting, the file is not in .STL (s I have selected) Instead the file format is " Certificate Trust List"

Is this the same with .STL file? I look at the file size which is pretty small, 386K. I keep wandering is it the correct one?

I have done everything according to the doc, everything fine except, instead of .STL I got Certificate Trust List.

Pls advice! Greatly appreciated.

Hi,

The issue still remain. Tied many times but still do not get the format I need. Someone from zbrush center, could you pls shed some light? Or anyone from the forum who happen to used the plug b4? Greatly appreciated.

The .STL extension is used for the Stereolithography file format, but also for the Windows Certificate trust list. Then by default, Windows display this kind of information, but be sure that the content of your file is the good one :slight_smile:

I may be wrong, by the 3D .STL file format is older than the windows certificate one :slight_smile:

And for the file size, the STL binary generate smaller file than the OBJ (OBJ isn’t binary). how many triangles or quads have your model before exporting in STL?

my model total poly is close to a million b4 exporting to STL. Getting the “CTL” format is ok then n save for output? Thanks a lot!

#5

The ‘Windows Cerificate Trust List’ is just how Windows is identifying the file from its STL extension, it has nothing to do with the file content (or indeed the type of file it is - this can happen when there is more than one format sharing an extension). So long as you are using the 3DPrinter Exporter plugin correctly then all should be well.

#6

Binary STL will be smaller than ASCII STL but for either type 386K is too small for a million polys. Make sure you are exporting all the subtools (if there are any) and at the right subdivision level.

#7

do you get a .STL or .CTL??

But 386 Kb for a one million mesh seems to be small. Can you try opening it in a software that can open STL files (like MeshLab)

#8

Ok, here’s the latest :slight_smile:

Re export the whole thing, now my file is 98091K. Seems promising instead of a small number. Yes, my file is in .CTL
From what the feedbacks, it seems to mean .CTL is all ok for 3d print output.
Thanks!

Having issue with Displacement map for my model. Posted it at this thread at:
http://www.zbrushcentral.com/showthread.php?p=627421#post627421

I have done:

-export DP maps using Multi Displacement 3 with DE-Lbek-EAEAEA-R32
-change preference>rendering to Use maya style alpha detection
-set MR approximation
-executed the mel script provided by Scott Spencer (bought the zbrush book)
-unchecked the “feature displacement” in attribute editor
-with all maps’s Alpha as Luminanace checked
-normal all facing outward
Using Zbrush 3.1 and maya 2009 on XP. And there is an eror message. Attached the image below.

Pls take a look as I have been scratching my head for soo very long. Appreciate any help at all.

I’m very surpised that 3D Print Exporter generate a .CTL. Are you sure that you didn’t type this extension by yourself?

And for your dispalcement problem, i’m sorry, I’m a modo and Max user, not Maya… (and I think it’s offtopic in this subject)

#10

I would guess that you are getting the ‘CTL’ from the Windows description of the file type (‘Certificate Trust List’) and the actual extension is hidden? In which case, you don’t have to worry.

#11

For your Displacement problem you should create a new thread with a title such as ‘Displacement problem between ZBrush and Maya’. Then you will likely get some relevant replies. Do not edit posts in a different thread (like you did in this one) as they will not get immediate attention.

Thanks,

Nope, I did not change anything in the format when using the 3d Print Exporter. I click on the STL Binary. When finished, the screen mentioned the file is in STL but when I check on my data folder, it is in .CTL, 95.7MB.

Regarding posting the DP map here, I’m kinna desperate…Sorry!

#13

The real extension is .STL, it’s because you don’t display the file extension as Marcus said.
you should enable Windows file extension display, it would help you :slight_smile:

#14

Thanks! I have my .STL extension now :+1:
Just in case for those who curious: to enable file extension for STL, go to folder option>file types>add STL by clicking on New
