Cinema 4D 2024 and Photoshop: UV mapping and texturing

UV mapping and texturing in Cinema 4D 2024 and Photoshop

Create, for example, a cylinder and make it editable by clicking on the Make Editable logo, so that the UVW tag is generated.
In order to UV unwrap object, switch to the UV Edit layout and select the object.
In the Texture UV Editor you can see that the UV islands of object overlapping each other and they are about the same size.
To fix it, go to the UV Packing tab of the UV Manager, select the Geometric radio button, check the Preserve Orientation and Equalize Island Size boxes, and press the Apply button.
Now, create new texture. To do this, open the File menu of the Texture UV Editor, click New Texture, rename it, for example, to CylinderTexture, and press OK button.
Initially, a texture contains only background layer. So you need to create a UV Mesh Layer that will be seen in Photoshop. For that, go to the Layer menu and click Create UV Mesh Layer.
Next, to save the texture as the file, go back to the File menu, click Save Texture, select PSD Photoshop file format, press OK button and save the texture file to your computer.
Now, open this file in Photoshop and apply, for example, a logo on the surface of the cylinder, and "top" and "bottom" texts on the bases of the cylinder. Next, delete the UV Mesh Layer and Background. Then, merge the remaining layers and save the file. So we got a Photoshop texture file with a transparent background.
To apply the created texture to the cylinder, go back to Cinema 4D, switch to the Standard layout, open the Material Manager, go to Create menu, select Classic Materials, click New Standard Material, open the Material Editor by double clicking on the material preview, go to the Color channel, hit the Texture, load the Photoshop texture file you created, click on the down arrow next to Texture and copy the shader of the Color channel, go to the Alpha channel and paste the shader, close the Material Editor, and then apply the material to the Cylinder. As you can see, the previously created texture with a transparent background is applied to the cylinder.
Now, you can apply another material, which will be visible through the transparent areas.
For this, create a New Standard Material, make it, for example, red, apply it to the Cylinder and move its material tag to the left of the previously created material tag in the Object Manager.
Finally, close the Material Manager and check the result.
