Realistic vinyl record tutorial

2. Realistic Vinyl record (Cinema4d r9 and up)

up

experience level –beginner

1. Search some vinyl record reference image with google "vinyl record"

2. go to top viewport and load image for the background. You may have to scale it down to fit the work area and your

disc object . (picture 1a and 1b.)

3. Create a disc object with inner radius of 1 cm and outer radius of 30cm (picture 2.)

In this part you also may have to scale the reference image to fit the disc object.

4. You can help your modelling work by creating a temporary transparent material

for vinyl record object. Create a new material, activate transparency and adjust transparency

value (brightness) to 50 percent. Add material to the disc object. picture 3a and 3b

5. Create a label for the record. Create another disc object with inner radius of 1 cm and outer

radius of 10 cm. pic 4.

How to create a realistic shader for a vinyl record?

6. Create a new Nukei shader (SLA shader in Cinema versions of 6-7).

We need to change the settings a bit to create a realistic material for the vinyl record object.

7. Change the projection type into flat in "Fusing" tab. Change color to black in "Diffuse A" and

"Specular 3 A". Activate the "Anisotropy A" tab and change the Projection into Radial Auto Planar.

Adjust roughness level into 1250% ; roughness Y into 50% ; amplitude 50% ; scale 50%.

See picture 5 and 6.

8. Add hypernurbs object and the vinyl record material to your object.

You may want to add some lights and background or whatever you like and that fits

your style and taste.

Here's what I've got in my setup.

 

Car tire modeling (works best with Cinema 4D version 9.5 and up)

Level: intermediate

This modeling technique will show you also how to do it very fast
and most efficient way in Cinema 4D.
Same polygon modeling technique is possible to use in
other 3d software such as 3Ds Max, XSI or Maya etc.
Please remember to use centimeters as units because it's important to have in order to use this tutorial. Also we get more realistic results when using real world units.

 

1. Start with tube and with the following settings:

-Inner radius 150 cm
-Outer radius 200
-Rotation segments 36
-Cap segments 2
-Height 100 cm

-Height segments 4 (edit: I forgot to put this, now fixed ;-))

We want to make the tire round. Just mark Fillet option on and
set 2 segments with radius of 20 cm.

2. Press C to make object editable. Then select 6 rows of inner polygons as
shown in the image A. Then delete them. You can use loop selection tool
in version 9 and up. B Change to point tool and click right mouse button ->
select optimize (picture C)-> click OK. This removes all unnecessary points.

3. We are still in the point tool mode. Go to Right or Front view to see your tire from the side.
Select second horizontal point row from top and second from the bottom. Just at the
tire edge (see image). Use the loop selection tool.

Select rotation tool and add value of 5 degrees in H
box. Click apply. Now we have some twist on the edges!

 

Next select first upper and bottom point rows next from the middle point row.

This time add 10 degrees of rotation in H box.
Click apply. See result below.

Now you can see how a simple tube is starting to look
more like a car tire. Next we will use the outer edge to model the tyre pattern.

4. Select polygon tool and select facing polygons as in the image.

Use bevel tool with extrusion of 2 cm and inner offset of 2 cm.

Click apply

 

5. A Select outer polygons around beveled polygons with loop selection then click right mouse button and select - split (B).

Now we have a pattern that we can use around the tire. Rename this part as tire_pattern.

A

B

6. Go to Functions - Duplicate. Select Linear mode. Put 35 copies and checkmark generate instances. Change all values into 0 in position boxes. Click Tool - apply. The pattern is now belting the tire. Only problem is that we have it now in one side only. This can be solved by using symmetry tool. Objects -> Modeling -> Symmetry .

Change mirror plane to XZ and drag tire_pattern copies and tire_pattern under it. Now you have pattern in both sides of the tire!

7. Now we have pattern on the outer edge but not in the middle of tire. Let's model middle pattern.

Select facing polygons and add same bevel values
as before (2cm and 2cm). Then select the beveled and its outer edge and split this pattern. Rename this for example as tire pattern 2. Then go to functions- duplicate and just repeat the function because the values are still the same.
Fantastic! Now you have made inner belt pattern
Just put this under Symmetry and you're done.

Remember to keep the hierarchy right, put tire pattern 2 under and inside tire
pattern. Otherwise it won't be visible to hierarchy of symmetry tag ;)

You can finally add some lighting, materials and background. Here's the final wireframe I've got.

Congratulations if you've made this far. Now have a can of Jolt or some coffee!

 

Background object tutorial (Cinema 4D version 9.5 and up)

Level: beginner (Category - compositing and rendering.)

In this beginner tutorial you will learn how to use background object and also how to use it in render setting in the correct way.

1. Create a camera

2. Create a background object

3. Create new material and load image in it. Please download and use this photo. We are using this photo as a background image and will also add 3d elements later into the scene.

4. Open render settings and check out the resolution from the photo. Adjust output resolution to the same as in photo.

5. Add the material into background object. You should be able to see the photo now in the background in your perspective window.
