Fish Tutorial


For a homework assignment set to us by Robin Ledger, we had to create a fish using the program Maya, I recently touched up on Maya in my recent blog post "Our First Try on Maya". To get to grips with what were going to be faced with over the next 3 years. Luckily for us we had Lynda.com to give us clear, simple instructions on how to create this 3D fish.

In a tutorial that has been created by George Maestri, we follow him while he shows us not only how to create a fish on Maya but to also use Maya's hidden tools such as the different ways of shaping an object and creating more vertices.

How we started our fish.
When I first went to set up the fish, I was told by George that it would have to roughly three and a half boxes across X and two and a half across Y. Once I had created this plane, I was told to rotate it 90 degrees so that the plane was standing up and facing me.

The plane rotated 90 degrees.
In the files that were provided with the Maya tutorial, we were given several files that would be linked to the lessons. I scrolled through and one of which was a rough picture of a cartoon fish. We we end up using this temple to create our fish to.

The reason that I created a plane was so that I have something to put the fish template on. The plane acts almost as a 3D piece of tape. We can then create a material on the plane and set it to the image of the fish template. 

The fish template pasted onto the plane.
As you can see from the picture above, this is how the fish should look when pasted onto the plane. What we are going to do next is to place a cube right on top of the picture of the fish and make sure that it is completely covered. The reason we are doing this is so that we can start to line up the actual model to the template and try to replicate as best as we can.

Once we have put the cube on top, we can then add some divisions on top of it. A division is basically the amount of lines that appear across the Y and X axis. With these lines, we can do many things. We can select the vertex, which is the meeting of the lines, as shown above as a little purple dot. We can select the edge, which is the line and we can also sect the face, which is essentially one side of box. For now though, we are going to be selecting the vertex. With the vertex we can move each individual one and place over the outlines of the fish template.

The vertex moved into the right position.
We can set it up so that we can see the fish drawing under the shaded block. The way that we do this is to select the shading in the top corner and then select the x-ray setting. This turns the opacity down on the block. This is very useful in situations such as this, so we can create the outline perfectly.

The next thing that we are going to do is create the tail fin, now I got this part straight away, I had to re-shade the fish then rotate so that I could see the back of the fish. Then by right clicking and selecting the faces, I selected the bottom two and then went to edit mesh, then to extrude. By doing this I can bring out the faces. as you can see in the picture above, I done it several times so that it gives me so much more variety when it comes to building the fin fully.

The extrusion tool is probably one of the most important pieces of equipment of Maya, this is used to create all sorts of landscapes. Its also very useful when trying to put detail into an object ready for a game.

The fish's tail fin now looks more realistic.
The is another way in which to get a different result when pulling the faces, you can, when you go to edit mesh, un-tick the button which says "pull objects together". This means that they don't pull in a straight line, they pull diagonally. I found this extremely useful when I went to go and create the lips of the fish. That was one of the things that I was worried about. I wanted the lips to be the same size, but not joint together and this is perfect for that.

Our next task from George was to create the fins. What we were told to do was to grab the lowest face and to extrude it. Once we had done this we would end up selecting the two faces on the top and bottom of the extrusion and add a wedge face. This provides a sample coming off of it on both sides.

The fins.

There is a really handy tool that is available on Maya and its called the insert edge loop tool. What this does is creates another division, along anywhere that you want. This is used if you want to add in that extra detail. For this tutorial, we were told that we would be using it to create the eye socket., again putting it in the Y and X axis. we would then end extruding it inside the fish and then deleting the faces on the inside to create a hole for the eyes to sit.

The eye socket.

To copy what we have done on this side to the next side, I simply selected the layer of plane that the fish template was on and have it made invisible. I then proceeded to select the fish by dragging over it and going to "edit" and Duplicate special. This meant that whatever I had done on the first side, it would be replicated on the other.

The duplication process.
By pressing 3 on the keyboard we get a smoothed out version. This works especially well when creating a smoothed skinned organisms such as a fish. This will give us a final product but first i had to add the eyes. I had some major problems when it came to putting the eyes into place. Firstly, the sockets themselves would not delete, so I had to improvise in this department by extruding them so far back that they could not be seen. Secondly I had to place the spheres into the eye sockets manually, which was a bit of a pain when it came to placing it perfectly.

I wanted to make the fish different, something that would make him stand out compared to the others, so I decided to make him a lot more plump. I managed to do this by grabbing the faces on each side and moving them out, giving the illusion that he is big.

The only thing that was left to do was the fin. This was something that I could do without the help of Mr Maestri, so I shut him down and did it myself. I grabbed the faces on the top of the fish and extruded them. Afterwards I scaled them together and thinned them out using various tools. 

The addition of the fin.
Now that I had finished the tutorial of the fish, there was nothing left to do, or was there? I decided that I wanted to go the extra mile and have my fish colored. The way I did this was to create a new material on top of the fish and color it in with one of my favorite camouflages. Once this was done I selected the mouth of the fish and choose that to be white.


Overall I am extremely happy how the fish turned out at the end. I love the way his eyes and mouth look. If I could improve one thing, it would probably be his tail, I feel towards the end, it could have been a lot thinner. 

I thought that the tutorial from Lynda.com was really helpful and I honestly believe that I learnt a great deal by using it. I am looking forward to doing a lot more with it soon.
