Hello friends and fans,

you might have been wondering what I was doing in the last few weeks. I'll tell you. ;)

A colleague of mine left us and I did not want to let her go without a small farewell present. I did not want to make another Canon cat for her (too many of them may become redundant :sticktongue:) but something "fresh". I found out that she liked dogs, Dalmatians in particular. Google brought me to this cutie:

It is a Pepakura model. I know that some of you despise the program. However, I have absolutely nothing to say against the program. It works as it should and without it I would not have been able to give you the Colonial Raptor, Colonial One, the stand for the Tiangle ship, Dr Zee's ship and many more.

If you encounter any problems with Pepakura models it is surely not the fault of the program BUT the fault of the creator of the model. And this Dalamatian puppy is one of these cases.

Even though I have given you the link to the model above I strongly recommend NOT BUILDING IT NOW. Wait for my rework. Trust me. If you try your hands at the model as it is at the moment, it won't make you happy.

There are several things wrong here: It has intersections, alternating flaps, a blurry texture and it was unfolded in a way that you break your fingers. To make things worse: The model is password protected, so you can only open it in Pepakura Viewer which gives you absolute ZERO options to fix any of the mistakes easily. All in all, this is a model to scare anyone off.

It's a model which drives me mad. It's models like this which make Pepakura look bad and which actually might hurt the community because with some LITTLE effort the designer could have delivered a perfect pattern. The texture is a different matter (it could be solved with Gimp), but releasing a model with intersections and this kind of unfold is a no-go. This is a prime example why you should never release a model without a proper test build before. NEVER EVER.

Knowing this, you might ask why I chose to build this model despite those issues. Well, it is CUTE. One of the cutest models I have ever seen, and this is the reason why I wanted to see if I could improve it. And boy, there was one tool which alone brought it from "so-so" to "superstar" - in one click! And I did not even asked for that!!! :cool::yesyes:

Well then, enough talk. Let's begin! :)

The model is 21cm long and has three parts pages. Since I wanted to apply some changes to the texture I printed a lined and a no-lined version to PDF. Then I turned the pages into PNGs using PDFill. I used a resolution of 100dpi because the texture was not hi-res in the first place and this helped keeping the file size down. My goal was to see if it was possible to enhance the texture in some way.

My first thought was: tracing it in Corel. This would have been possible, but this would have required some work. Since I did not know if the pattern would look good in the end I did not want to spend too much time on it. I took a look at the head:

You can clearly see the bad quality of the graphics. Improving them was crucial for the project. If this could not be done, it would have been shelved and I would have jumped back onto the cat again.

Then something unexpected happened. A few weeks ago Nano Banana 3 was released. I already saw some improvements in the renderings compared to v2.5 and I thought, maybe it was able to at least make the image sharper. So I uploaded the snippet above into Gemini and asked it to improve the texture. This was the result:

Gemini_Generated_Image_hatdwnhatdwnhatd.png

Well.

It did something but the result was not what I wanted. It sharpened the blurry texture, but instead of creating a new image with a sharp texture it created a new image with "sharp blurs". I know it's nitpicky but it's exactly what happened. Hm.

I took a look at the conversation again and it dawned to me that I may have worded my query in a wrong way and asked for the wrong thing. So I started anew and tried another prompt. I explained to it what my goal was and that I had a paper model template with a blurry texture which should be enhanced and sharpened. The result would mean the rise and fall of the project.

After a minute or so it gave me THIS:

Gemini_Generated_Image_gwkflcgwkflcgwkf.png

And this, ladies and gentlemen, absolutely knocked off my socks!

Please take a close look at what happened: I asked it for a sharpened texture. It went above and beyond and made everything crisp and clear, and added a realistic fur texture on top! Something I had not asked for but something Gemini added on its own after I gave it the information that it was a pattern of a dog. And just look at that nose!!! ABSOLUTELY AMAZING!

I went ahead and fed all three parts pages to Gemini and repeated the procedure. The results were stunning.

It had a small hiccup on the feet and spread the padding and nails across the whole foot instead on the bottom of it only but that could be solved in Gimp.

The colour was tweaked in Gimp and lightened up. A few parts had a very rough fur texture which stood out a bit. I uploaded the image to Gemini again, marked the parts in question and asked it to adapt the texture so that it blends in with the other parts.

I was lucky camper! :)

Please note that this edit took place after the first test build, so the following images show still the long fur texture.

This is a prime example of how AI can be used as a tool.

The pages were printed and assembly could begin. :)
 
I started with the head. It was very straight forward. Since it was the very first build I did not change the flaps or the unfold to see how everything went together.

IMG_20260325_182059.jpgIMG_20260325_191920.jpgIMG_20260326_095903.jpgIMG_20260326_095825.jpg

IMG_20260326_095523.jpgIMG_20260326_095605.jpgIMG_20260326_095720.jpg

A funny thing is that the mouth is actually parted. You could adapt the template so that the dog really smiles!

IMG_20260326_095648.jpg

The back of the head:

IMG_20260326_095424.jpgIMG_20260326_095442.jpgIMG_20260326_095400.jpg

There are two flaps for the ear on each side:

IMG_20260326_095316.jpg
 
Now we come to the first weird design choice: The ears are parted in the middle. You must not use the flaps to close them but to combine the two halves. One face is in the wrong place and had to be cut off and attached to the other half.

IMG_20260325_191945.jpgIMG_20260325_192019.jpgIMG_20260325_192039.jpgIMG_20260325_192107.jpg

Another face was in the wrong place:

IMG_20260325_192138.jpg

The result was not too bad but those cuts in the middle were jarring.

IMG_20260326_095107.jpgIMG_20260326_095131.jpgIMG_20260326_095225.jpgIMG_20260326_095241.jpgIMG_20260326_095304.jpg

Something to deal with later.

I continued with the limbs and the body. Basically they are not too bad BUT the feet are attached in a way that you cannot apply pressure to the flaps! They are alternating and while one bend up the other one bends down. There is no way you can achieve a pleasing result.

IMG_20260329_172522.jpg

Moreover, the front legs have an intersecting face which is better cut off. I saved it for later which was a good idea.

The hind legs were a bit better:

IMG_20260329_221608.jpg

IMG_20260329_221550.jpg

The body and tail went together easily.

Now it was time to decide which part should be assembled next because if I went too fast I might block the access to the inside. I chose assembling the hind legs first:

IMG_20260330_223139.jpgIMG_20260330_223159.jpg

Then they were attached to the body:

IMG_20260330_222943.jpgIMG_20260330_223031.jpgIMG_20260330_223055.jpgIMG_20260330_223123.jpg

The Pepakura model sowed an intersection between the hind legs and the body. Much to my surprise I was able to squeeze the parts together so that this intersection was negligible. You can see a nice place for the tail.

IMG_20260330_222909.jpg

I attached small pieces of leftover paper to seal off any gaps caused by the alternating flaps. Next time I will cut off all flaps and use glue strips wich should make this step obsolete.

Funny side note: When I looked inside the body it looked like a hippo. :biggrin:

Next was the head. A very straight forward task.

IMG_20260330_222728.jpgIMG_20260330_222753.jpgIMG_20260330_222809.jpgIMG_20260330_222848.jpg

Now I reached the most difficult area: The arm pits. The model has some severe intersections in these areas which required some fiddling. A test fit:

IMG_20260329_231053.jpg

I used the part that I cut off earlier and glued it into place:

IMG_20260330_222644.jpg
IMG_20260330_222542.jpgIMG_20260330_222616.jpg

Then I guesstimated the approximate angle, checking closely the model in the Pepakura display window. It is a straight angled cut. Nothing to be afraid of.

IMG_20260330_202112.jpg

But then things got tricky. The first arm went in without trouble. But the second required some extreme fiddling because there was no space to apply pressure to the flaps. I worked carefully, attached one flaps at a time and pulled the armpit outward with some tweezers.

IMG_20260330_202334.jpgIMG_20260330_202414.jpg

You can clearly see the gap in the foot which was caused by that darn flap placement and Jenga unfold.

IMG_20260330_202045.jpg

And finally the puppy stood on its four legs!

IMG_20260330_205744.jpgIMG_20260330_205834.jpg

Well then. It was time for the second upgrade - fixing the seams on the ears! I re-arranged the outer ear pattern and combined the split parts.

IMG_20260330_222138.jpg

Then I laminated them over the seams:

IMG_20260330_224423.jpgIMG_20260330_225005.jpgIMG_20260330_231233.jpg

Like night and day. :)
 
Next was the stand. I chose the same box construction which I made for the Pegasus:

IMG_20260331_140239.jpg

A rough skeleton was inserted:

IMG_20260331_140255.jpg

And the sides were covered with blue card:

IMG_20260401_204326.jpg

I did not want the model to shift and gave it some foot mounts. This was a really easy construction of four blue card rectangles.

IMG_20260404_205941.jpg

The white piece was a mockup to see how the blue card was supposed to be folded and attached.

They were scored and cut in:

IMG_20260404_210328.jpgIMG_20260404_210556.jpg

Then I put the model on a sheet of paper and marked the position of the legs. I made some small cuts into the paper and pushed the blue mounts through.

IMG_20260404_211215.jpgIMG_20260404_211228.jpg

IMG_20260404_211308.jpgIMG_20260404_211319.jpg

IMG_20260405_134415.jpg

I folded up the incisions on the white paper, put it on the blue card which was supposed to be laminated on top of the box and traced the positions of the mounts.

IMG_20260419_143700.jpg

The traced lines were cut in, the mounts were pushed through and glued tightly to the back.

IMG_20260419_150351.jpgIMG_20260419_150325.jpg

The plate was laminated to the box:

IMG_20260419_150615.jpg

And the box was decorated with silver glitter stickers:

And here we go, the Dalmatian puppy papercraft, ready for dispatch:

IMG_20260419_185548.jpgIMG_20260419_185554.jpgIMG_20260419_185600.jpgIMG_20260419_185606.jpgIMG_20260419_185612.jpgIMG_20260419_185645.jpgIMG_20260419_185648.jpg

The pictures show every flaw of the model, I know. It looks better in person, so this is the one which will go to my colleague. I will be working on the revision of the template in the next weeks on an on and off basis. The model is cute as a button and will get the attention it deserves. Stay tuned for updates! :)

And remember: If you have a model with a texture which is lacking - use Gemini! It may not work wonders but sometimes it does. :)
