Read Importing and Applying a Decal Texture in UE4 Now
Importing Textures Into UE4

Welcome to this tutorial, today we are going to work on bringing textures into your game. We are going to cover three different types of textures and how they can be imported into your game, along with how to apply them.

Sample Decal Texture


Step 1: Importing a texture


The first thing we need to do is source a texture.

I’m going to use a rust texture made in an earlier tutorial and import that into my game. The first thing we need to do is import the texture into Unreal. To do this open your game. Then in the context browser select the Starter Content folder and in the textures folder we are going to select import.

We click the import button beside new.

The file type for the decal should ideally be a .TGA (Targa File). Once you click import you will be asked to select the file, locate your file and click open, but make sure you select the TARGA file type and not the .PSD file.


Step 2: Creating the decal material

My texture has been imported into the game. Now we need to add a material.

The texture is imported but the star symbol means it is unsaved.

To add the new material scroll down to the bottom of the textures folder and right click in an empty space, from the pop up menu select the material option. Then name your material decal rust. 

Here we can see the blank material that I have created.

If you then double click on the newly made material, it will open the material editor which should look like this.

Our texture is not in the material editor yet, that is why the ball is black. 

Now the problem here is that we have no actual image to create our decal from, so what we need to do is take the imported decal from our content browser on the left and drag it into the grid on our material editor.

The decal  has been brought into the material editor.

The next thing we need to do is connect the decal to the info panel.

Here we connect the detail to the info panel.

Once this is connected click on the info panel. The options on the left will change.
What I've done below is selected the info panel and changed the blend mode from opaque to translucent. This is one step closer to eliminating the background so the decal goes on without a pure white background.

The details on the left hand side have changed.

We connect the bottom most channel on the texture to the opacity option on the info panel.
We also need to change the material from a ‘Surface’ to ‘Deferred Decal’. The result is we now have a decal texture. Hit save at this point.

All I did here was click the black triangle beside surface and select deferred decal.


Step 3: Applying the decal material

Now that we have this done let’s get a surface prepared to apply the decal to.
What I have done in the below picture is I’ve opened the starter content folder and I dragged a copper material from the materials folder directly onto the wall.

Note: the material came from the materials folder, not the textures.

Now that this is done we need to take in a deferred decal from the place section under the visual option scroll down to find deferred decal. Once you drag this into the game this is how it will look.

The material we created with the decal needs to be applied to this.

Now that we have entered the deferred decal we need to actually connect our decal to this decal.
To do this drag the material you created in the textures folder and drag it over to the materials box on the left hand side.

We drag and drop the material into one of the empty boxes and this will apply it.

Now to get this decal to actually work is going to take some manipulation, because of the way the deferred decal is positioned, so with it selected, hit the space bar in order to bring up the rotate widget, then click and drag along the blue and red arcs to the decal to rotate into a position that you are happy with. 

The purple arrow tells us the direction in which the decal is facing.

Now I'm happy with the location but not the scale. So if you hit space again you will get this widget (below) this is used for scaling and I'm going to scale mine till I am happy with how it looks.

Clicking on the green arrow and dragging up or down will scale the decal.

I'm happy with the scale of this decal. Now we are finished applying the decal we can save the progress and move on to the next texture.

In this tutorial you will learn how to add a texture in Blender using Cycles render.

Step 1

Using whatever you have made or imported change the default screen layout to compositing for a detailed result.

Step 2 

Change blender render to cycles render at the top of the screen.

Step 3

Right click in the plane, click on the material button on the top right corner of the screen, click new.

Step 4

If a material is already in place use the subtract button then press new.

Step 5

Click on the dot right of the white colour.


Step 6


Select image texture, press open and navigate to the image you want to use, once selected open the image/texture.

Step 7

To map the image on the plane go to edit mode by pressing Tab or changing it from the bar menu.

Step 8

Press A to deselect then A again to select everything. go to mesh, UV unwrap, unwrap.

Step 9

On the left side the plane will be unwrapped. Next load the image.

Step 10 

Switch back to object mode, switch back to the default layout, go to render to see the result.

Chair with texture

In this tutorial you will learn how to create a basic chair and add a texture onto the chair.



Step 1

Delete the default cube by pressing X and delete.

Step 2

Add mesh plane or shift A mesh and plane.Zoom in with the middle mouse button, or press 1 for a side view, press Tab to go into edit mode it should turn orange. E to extrude.

Step 3 

Press 7 on the number pad to get a better view. Use the middle mouse button to zoom in or out.

Step 4

Press ctrl R to create a loop and place a loop at each side. Total of 4 loops.

Step 5

Select face select.

Step 6 

Press the number 8 to flip to the opposite side(underneath the plane),Select one box then press Shift and right click on each of the boxes.

Step 7 

Press number 1, press E to extrude to your desired length. Use the middle mouse button to move around to get different angles.

Step 8 

Press A to deselect, select one side and E to extrude.

Step 9 

To add a texture onto the chair go to materials bar on the top right corner of the screen, click on new.

Step 10

Change the specular to zero so a glossy effect wont appear onto the chair.

Step 11 

Go to the texture section beside the material on the top right corner, click on new, change the type image to image and movie, click on open and navigate to your texture that you have downloaded.

Step 12 

The texture will look like this on the chair, to fix this the texture needs to be unwrapped. Change object mode to edit mode.

finished result 

In this tutorial you learn the necessary skills on how to make a sword. In this tutorial we will be making a Japanese Katana.



Part 1 The Blade


Change to cycles render

Press shift and tab for the snap during transform button or hit the magnet button, select the top vertex

Turn proportional editing and snap during transform off, select the outside of the blade by pressing B and dragging it along the left side or by selecting each vertex individual by hitting shift and right click, E to extrude on the X axis a small bit.

Merge the top vertex, move the bottom one slightly to the right

Press A to select everything, change view by 3 on the keypad, E to extrude.

Merge the two points together

merged points 

Select the next vertex underneath the top point and its opposite one press W , merge, at centre do this to the rest.

To fix the lighting and shade go to mesh, normals, recalculate outside or inside this will prevent the blade from being dark at certain angles.

Normals 

Tab and smooth. the smooth button is to the left it will show if your out of edit mode. add a modifier, subdivision surface, change render to 1.The blade will look off, go into edit mode by pressing Tab, select the these 4 vertex

subdivision

4 points selected




To fix the problem that will happen go to mesh, edges, edge crease. once clicked drag your mouse across the screen to the right side. this fill the empty space, repeat this for the bottom of the blade.

To add a flare onto it create a loop cut ctrl R lenght wise twice

Press E to extrude and right click straight away so it sits on top, S scale on the Y axis pull it in to your desired depth. Then add edge crease to make the depth stand out.
