4.1- Using several objects

If you are working with several objects (primitives) on 1 screen , and you want to make changes upon only 1 object, then you must lock the other objects , in order to avoid that you make changes upon the other objects.

Select first the object that you want to change .
Then choose :  Select > Lock Unselected Objects.
Then you make the changes for the object . On the other objects, there won't be any changes .
After this, you can unlock the object again :
Then choose :  Select >  Unlock all Objects.

You can use the same methodes by making the other objects invisible. This is useful if you have objects that are inside another object (or partly hidden) . By making objects invisible, you can see better which changes you are doing upon that object.

Then choose : Select > Hide Selected objects  / or : Hide Unselected objects
And after the changes, then choose : : Select > Unhide all objects

You can also press upon the spacebar, but then all faces and edges will be deselected.

4.2 - Making textures for your objects

Important to know : 1 texture belongs to 1 material

The first step is : we make in advance the names of our materials :

As an example, you make a cube but you select nothing yet. Now right-click and select Material , and then you type a name for your material : eg.: material2 and click ok.

In the toolbarmenu you select :  Window >  Outliner.
In this Outliner-window you will see the material "material2" is in the outliner box. Later you can link this material with a texture.

The second step (if needed) : we make a material with colourcode or transparancy

We choose again a cube primitive and we select nothing. Rigth-clcik in the screen and choose Material. Now type a name for you new material and click ok. Now we see a window where we see "Diffuse", where you will see also a white square : click upon that square and choose a colour.

A bit lower on this window you will also see "Opacity". Here you can move the sliding bar between 0 and 1.

The third step : link a texture to a material

Go the the toolbar-menu : Window > Outliner : and you see the Outliner window-box.

Then to to the toolbar-menu again and choose : File > Import Image > and now search on the maps of your computer and choose a texture.

The texture you have chosen will be in the Outliner-window.

Now your must left-click upon this texture, in order to select it, and then right-click and choose : "pick up image"

Now you must left-click upon the material , in order to select it (the material upon you want to make the link), and then right-click and choose ''drop picked object" , and then you get a little window and here you choose '"diffuse".

The fourth step : check if the link has been done correctly

Now in order to check if the material has been linked with the texture, left-click upon the material to select it , then right-click and choose "edit material" : You will see now in this window a large circle at the left with the texture (if the linking has succeeded) and a bit lower on this window , where you have textures/diffuse , you will also see the filename of the texture .

In the model-examples that we will make, you will see how we can add those materials/textures to the object.
