Creating stickers - Knud Ahrnell Albrechtsen - 2018-07-16
Hi
I usually create stickers to my instructions with sticker generator.
Does anyone know if there is another piece of software that can generate stickers - preferable at a higher quality than sticker generator?
Thanks

Thaks for the reply.
I have looked into this program but I couldn't see how I Import a picture and convert it to a .dat file??
RE: Creating stickers - Johann Eisner - 2018-07-16
Hi again
There is no way to import pictures. You have to draw the pictures yourself. You can set a picture as a background and then you have to draw, draw and draw. ;-)

Is there no program that has a similar functionality as sticker generator ?
But with a better end result

Textures are a fairly new LDraw feature so not all software supports it (yet).
LPub should support it trough LDView though.
MLCad doesn't support textures as it is not maintained anymore.

If you are running 64-bit Windows, you probably need to copy any ocx files to the SysWOW64 folder instead of the System32 folder. Also, you probably need to run regsvr32 from the command line:

Hi Roland
I have now started using LDCad instead and it looks lige it supports textures.
But I have run into a couple of problems I hope you can help me with.
the first one i whitespaces in the image path. How fo I get it to handle this?
I have tried both:
T:\folder\My Folder\sticker.png
and
"T:\folder\My Folder\sticker.png"
and
'T:\folder\My Folder\sticker.png'
but it will not accept the path if there is whitespaces.
If I copy the sticker to C:\temp\Sticker.png then there is no problem
The other issue is that when I open the sticker.dat file in LPub3D with sticker in C:\temp it does not show the sticker, only an empty square.
The renderer in LPub3D is set to LDView.
Sticker in LDCad

I checked the sourcecode and you're right it will only use the first "word" as the filename, this because it can be followed by other stuff.
This is a bug, and will be fixed in 1.6c.

Are you sure lpub is using the same LDView exe as when you run it standalone?
Secondly I'm not sure the current LPub3D version copies the texture files to its temporary output location (from where LDView generated its images). You might need to do that manually.

the next problem is to get the stickers shown when rendering in POV-Ray.
Is this possible???
Currently this is the issue.
Stickers in LDView (4.4 a):

Stickers in POV-Ray (3.7)

RE: Creating stickers - Travis Cobbs - 2018-08-27
LDView's POV export does not support textures. I think LDCad's POV export does support textures (although I'm not 100% sure of that). I have spent a fair amount of time trying to support textures in LDView's POV export, but haven't had any success. I haven't totally given up, but I'm not willing to promise anything at this time.

does it have a problem with whitespaces?
when i try to export LDCad creates the folder but then shuts down without creating the pov file.

For the pov export all needed png's are copied into the pov export destination using generated names so spaces should not matter.
But if LDCad crashes during the export it might be the cause of it on that side, I'll have to look into this some more.
It would help me, if you send me your model so I can test it myself using similar input.
You can prevent the space in folder names by using relative filenames only (place the png in the same folder as the .dat)

It helped copying the png files to the same location as the dat file.
Then I tried exporting the model using the below settings.
![[Image: ldcad_povray_export.png]](http://snakebyte.dk/lego/ldraw_forum/ldcad_povray_export.png)
Then I commented out this line in the generated file for better comparison:
//background { color srgb 0.4 }
After rendering the stickers are show so that is great but I am not happy with the result in the colors.
try comparing the DBG with my export from LDView 4.2 (without sticker)
I think the DBG looks very "flat" compared to mine??
Any idea why it looks like this??

Not sure could be a couple of things, like:
- Light position
- Camera position (you can't really compare to different views)
- LDCad using srgb and LDView using rgb (I think) in the .pov.
You can tweak the colors by copying the
default
folder to e.g. "MyColors" in
%appdata%/LDCad/povray
Then edit its colors.pov to suit your needs.
In the export dialog select "myColors" in the "code donor" field.
You can then also disable the background, you edited out, by default in globalSettings.pov

Light position is the same.
cameraposition is - almost the same.
no matter what position I have used it is the same difference.
I did the export to pov file directly from ldview in both versions .
I did not use LDcad for the export.
Editiing the colors like you suggest is a bit over my underrstanding of POV-Ray im affraid
I think I found the differnce.
in ldview 4.2 and 4.3 the color section starts with
#include "lg_defs.inc"
#include "lg_color.inc"
This it doesnt in the 4.4 export.
I tried replacing this section from the above includes to down just before this line:
#ifndef (LDXColor494) // Electric Contact Alloy
that seems to correct the difference in the colors.
Could I put this in the colors.pov file - would that work??

You can use the non macro way in LDCad but it will need some high level POVRay 'magic'.
I think the main reason of the difference is the fact the LDView export uses LGEO which comes with its own color defs while LDCad uses the RGB colors as supplied in the LDConfig.ldr file.
Also LDCad's pov export was designed mainly for animations so I sacrificed quality over rendering speed at some points.
If anyone with deeper knowledge of LGEO inner workings know the basic differences and point them out to me I could make an alternative colors.pov implementing it.

I've tried using a .dat with an abs png file name with and without spaces used from a mpd inside a different/same folder etc.
All works for me without a crash.

I'm just trying so but obviously I didn't understand how to use the Melkert code generator.
I followed the instructions on the site. Since the 93606 is a 2x4 I set width 40 (ldu) and height 80 (ldu)
I entered the PNG name and pressed Generate.
I copied the code into an empty dat file and saved it in the ldraw / Unofficial / customparts / parts folder (which is correctly read by Lpub3D and LDCad).
Opening it with LDView it is correctly rendered but I don't understand how to use the sticker just created on the curved surface of the piece in question (93606).
Could you give me a hand?
thank you

Please note that it will only create a correctly folded top surface. The backside "box" is not correct (but it makes a good attempt).
It looks like the top surface is folded, but then the box is projected down, to the brick top surface...
You will also need to clean away many "new" vertices created at the folding lines.

What renderer are you using for LPub3D? If it is LDView, LPub3D has a privately built LDView executable included with it. That executable isn't based on any official (or even Beta) LDView release. That could be causing the problem. If you're not using the LDView renderer, switching to it might fix the problem (although it will slow things down by a lot, AFAIK).

Same result.
I think i will use a custom part with box5.dat and the image to show the sticker applied over the part instead of directly replacing the oblique face of the part with the image file.
Thanks
