Model project - Cromwell tank

Cromwell Tank
Working Project


I have been working on many models in the past and in that time many people have asked me the question “How do I do it?” or “Can you give me some guidelines?”. Usually I answer with a simple answer that is not quite enough for them. That’s why I have decided to give a detailed look into the progress of how a S&M model is made and you can be part of it also. Tell me what you think should be changed or how something should actually look. From making the model and even to the part when texturing comes we will take a look of everything. The project starts from scratch. Nothing has been made yet and this first post will give the insight of the model we are about to create. Enjoy the journey and take part of it. If you have Blender and Photoshop you will have access to all the files produced in this project so you can take a look with your own eyes of how it’s all done.

Cromwell Tank
It was one of the most successful series of cruiser tanks used by Britain in World War II. It was the first tank in the British arsenal to combine a dual-purpose gun with a power engine and a balanced out armour. The Cromwell first saw action in June 1944, with the reconnaissance regiments of the Royal Armoured Corps.

Place of origin - United Kingdom
In Service - 1944 - present
Type - Cruiser tank
Crew - 5
Speed - 64km/h

Day One
You sort of start thinking anything’s possible if you’ve got enough nerve - J.K. Rowling


Every project starts with a bit of research.I always look up images and videos to get a brief overview of the vehicle I’m working on. Obviously blueprints play a big role in that. A great artist named Vincent Bourguignon has made hundreds of blueprints based on ww2 and ww1 armory. Visit his site here. The blueprints I am using can be found here.

On day one we will look how the make Cromwell Tank turret was made.

On a close inspection we see that the turret itself is not very complicated. However it does have some smaller details that we want to include to the model (Numbers one and two). The most problematic area of this turret is the front side. The hallow inside (Number three) of the turret must be done with care. If it’s done wrongly it will cause problems in the texturing part. The only shape we actually need to use on this turret is UV Sphere. The rest of the tank will be done by single plane faces in Blender.

Those of you who have used Blender before will understand more easier what is written next here. Also this is not supposed to act as a tutorial.

I start the process by doing the top part of the turret. (Number four). This is easy to do with a single plane face. I duplicated the vertices of the single face three times and manipulated them into place according to the blueprints. That way we have the top part of the turret already made and ready for duplication to give it some width.


Image#1 - The width of the turret expands. Work time 9min

Next I did the hollow entry of the turret. This was a bit more complicated to do because of the awkward shape it had. Multiple faces had to be connected with each other to form the needed shape without using too many vertices. Sad part about is that texturing will suffer from it and many faces had to be formed.


Image#2 - The hallow entry for the gun has been made. Work time 20min

With the hollow entry done it was time to include the armament on the tank. Cromwell tank has a 75mm tank gun which is quite a mouth full but with a basic construction style it was very easy to make. Using UVSphere with 10 segments the turret turned out round enough to feel smooth.


Image#3 - The simple style made it very easy and fun to work on. Work time 27 min

With the main armament done it was time to move on to the detail. The big detail was done first followed by smaller detail. All that was needed to do was a few faces in the shape of a box for the few square type hatches and round hatches done using UV Sphere with 16 segments. I decided not to include all of the tank details 100% because it would be way too much. However smaller details like the bolts I decided to include on the turret because having to do them in texture does not look so great.


Image#4 - Big detail on the tank has been finished. Work time 39 min

The smaller detail consisted mostly of bolts on the sides of the turret. They were made out of UVSpheres but then turned into cones to reduce vertices count. It also made the texturing part easier for later on.


Image#5 - Small detail added. Work time 50 min


In less than a hour the Cromwell turret had been created. It has 694 vertices and 570 faces which is quite a large amount compared to the standards of Enemy Territory. It was very easy to make due to it’s box type shape that is similar to the Tiger Tank. You can check the work yourself out if you have Blender. Downloadable files are in the thread end.

Give your thoughts and ideas. Open the files and modify them to your need and share them here. Also I am happy to see some interest in this.

Day Two
Beginning is easy - continuing hard - Japanese Proverb quotes


Next to do on the list was the tank body. Taking a closer look on the blueprints we can see that it mainly consist only of box shapes. Simple.

First the body has to be shaped out before anything else. That will give you the full view of the vehicle body. It was relatively difficult to figure out exactly what the shape of the tank is so I had to scrap the body two times to get something that looked similar.


Image#6 The shape of the body is simple. Work time 1 hour.

Once the body was complete it was time to add the track covers. This is also a very easy step. You just need to use a single plane face and duplicate it many times until the shape in need has been received.


Image#7 The track covers protect the tank from mud. Work time 1 hour 15 minutes.

Next to do is the little details. The shapes are exactly the same as on the turret. Using cones and plane faces the results come in fast.


Image#8 Fast and easy. Work time 1 hour 27 minutes.


The reality is that making the tank body is by far the simplest part of a tank model (On models I have done). It’s hard to mess it up because the shapes are very easy and anybody can do it. Texturing is also simple on this part but critical as big plain areas are seeable to the player so those areas need extra care.

Thank you for sharing your work - have always wanted to try some model work - but never got to it.
I will try to follow this one and see where it gets me.
If i fail …i will get back to you :slight_smile:

No problem. Good luck! If you ever get in trouble you can write it here or contact me over MSN. You can find my account on my profile.

Thanks. Next to do will be the tracks. Then we turn our eye into the texture. That will have more detailed instructions.

Always wanted see nice example of this, I get the principle behind textures UV space but it’s easier said than done :slight_smile:
