Paint Brush Tutorials (2016)
These are old 4D Paint Videos that were created for the initial release of the Paint Brush a few years back for R17. Many things have changed since these videos were created and some workflows are outdated. But in some cases these videos may still provide useful tips and tricks to help you with your painting.
It is preferred to use the new Material View and Layer View when dealing with layers in 4D Paint instead of the BodyPaint UI. In some cases this is still very useful, in particular painting on layer masks and also working with Multi-Channel painting.
Paint stencils down onto your models. By painting on a stencil it will project the stencil directly down onto the model, including symmetry. Also use the rectangle and poly modes to project a larger area of the stencil down onto the model. Use any Cinema 4D Material as a stencil. Allowing you to use all the procedural shaders and noises for painting, including multi-channel painting and Allegorithmic Substances.
Paint onto your models using Stamp images. Change the Dab Spacing to apply stamps at regular intervals on your model. Use PNG images with an alpha channel to get just the right shape and look. Use any Cinema 4D Material as a stamp, allowing you to use all the procedural shaders and noises for painting.
Use all the power of the Sculpting Symmetry settings to also paint onto your models symmetrically.
When painting the brush will project down and place the texture onto the selected Layer in BodyPaint, for the material being painted on. If you have a Mask selected then it will paint directly into the Mask.
Edge Detection has been included to allow filling parts of the model based on its curvature/flatness.
Paint directly in the OpenGL Viewport onto Polygon Objects. Each brush dab is projected down onto the surface of the object with the paint being applied to the currently selected Layer in BodyPaint. You can paint using the currently color set in the BodyPaint UI or directly apply Stencils or Stamps. You can also use all the Sculpting Symmetry abilities to ensure your painting is symmetrical.
By painting directly onto an image in a Mask Channel on a Fusion Shader you can blend between 2 different Surface Textures.
Paint a single brush stroke over Multiple Materials. Each material can have its own selected Layer in BodyPaint and the paint information will be projected onto each of the correct layers for each Material. Including when multi-channel painting.
A special option to simply flood fill every polygon that the brush touches. This allows you to quickly block out areas of your model with color or, when using Stencils, it will project the Stencil onto the whole polygon in one go. The brush will also respect the Pressure value.
You will also get a brush that is capable of sculpting and painting at the same time. This feature is a bonus experimental feature that will get more updates in future releases.
Paint directly onto a Polygon Object and alter the texture used for the Displacer Deformer. Together with the real-time updates you can now do basic sculpting by texture painting directly on the surface of an object.
Fix up any seams you have painted over with the quick Bleed option. This will bleed out any texture from your UV Islands out into texture space allowing you to fix up any seams after you have painted.
Some objects, such as the Relief Object, can use textures. The paint brush has some update options to allow you to tell C4D to update the objects after, or during a stroke, while you are painting on a texture. This allows you to see real time updates of the Relief Object in the viewport as you paint on a proxy texture. See the videos for more details.
By using a Material as the Stencil or Stamp you can projection paint any procedural Material directly onto the surface of your model.
Using the Rectangle or Poly Fill modes you can select an area of the Stencil that you would like to project down onto your model.
To get a feel for the texture on your model a one click button is included on the brush that will fill each of the UV Islands with a random color and apply this to the selected layer in BodyPaint.
A quick one click button to flood every UV Island with the currently selected color. This could be thought of as a flood fill button but with the exception that it doesn't paint the entire layer, only where the UVs are on the layer. This feature also respects the Selected Polygons when in Polygon Mode. In this case it will just fill only the UVs for those selected Polygons.
Restrict your painting to just the selected Polygons when in Polygon Mode. Selections will also be used when using the Fill Button to fill all the UV Islands.
