Are they any tutorial on how to make a head using front and side rotoscopes. I see there are many pictures that come with trueSpace. I have tried to make 2 panels for the front and side. The problem I have is how to work out the size of the panel. I am not sure how you worked out 8 for the width and 6 for the length for the viper fish as the original image dimensions were 1024x768. Is there an easy formula to follow for keeping the picture from stretching.

I think he divided the picture size 1024 and 768 by 128 to get 8 and 6.

I know that but why choose 128? Do I use this number 128 for all my image templates?

So long as the ratio of width to height for the plane is the same as the ratio of width to height for your image, you are fine. Otherwise, you will stretch or compress the image in one direction or another.

So for a 40x40 image you can use 10x10, 4x4, 1200x1200 etc for your plane in tS. Or for 40x80, you can use 10x20, 4x8, 1200x2400 etc. And so on.

There's nothing magic in the 128, it just gave a nice size of plane to work with in the space I suspect :)

The properties of for you image should give you its pixel dimensions. The easiest way to translate that to the dimensions for your plane in TS is to add a decimal point to those dimensions and enter the result into the info panel X and Y BB Size for your plane.

So for instance, if your image is 600 pixels wide by 317 pixels high, use 6.00 for your X BB Size and 3.17 for your Y BB Size.

Once you have your image applied as a texture to your plane you can resize the textured plane to make it larger or smaller.

Don't forget that you can also use math functions in the panel fields. This comes in really handy for resizing to specific scale.

If using Workspace you could try the Magic Box:
