How To Make A Nut Chocolate Fluid Ad With Cinema 4D
This time the best render farm in the CG industry, Fox Renderfarm, will bring you a Cinema 4D tutorial on how to use C4D to make nut chocolate fluid ads. This sharing comes from 3D artist Qixi, who will explain in depth the production process of a chocolate and almond scene. I hope it can help beginners who step into the CG industry understand the use of C4D. Since this scene is just for making still-frame works, there are many things that don’t need to be considered too much, as long as the picture looks reasonable.
Before making, I first searched for some pictures of nuts on the Internet, and then found a positive picture of nuts, and then used Mesh/Polygon Pen for topology modeling. When making, I need to pay attention to keeping the model as quadrilateral as possible. The surface (triangular surface will cause many problems in the later production).
First, make the upper half of the model, adjust it slightly, and then use the subdivision surface. The arc shape is to draw an arc upward by adjusting the edge. Try to keep the shape similar to the reference picture.
Use the Symmetry tool, and then complete the nut model. Because the shape of the nut is very simple and there are not many tools used to make it, this step should be easy to do.
The nut model has been completed, and then I will split their UV first. The model splits the UV first and then copies it, which can save a lot of time for splitting other UVs.
Add UV tags, then use the projection mode to disassemble the model up and down, adjust it and export it to Photoshop to make a map.
I cleaned up the clearer one in the reference image I found before and then aligned the texture to the outside of the UV grid. I made a total of 5 stickers for this nut. Below is the first Color Map I made.

The third Displacement Map
The fourth Bump Map
The fifth Normal map
Below is the nut effect after adding 5 textures. I think it looks very much like a real nut.
To make a bunch of nuts
Now that a nut has been completed, I will turn it into a pile of nuts in the next step. In this process, I used cloning and rigid body dynamics for dynamic simulation animation, and finally got the final scene.

Chocolate sauce effect
Next, this pair of chocolates need to add some effects. I want some chocolate sauce to flow down from the pile of nuts. This fluid effect needs to be made using the C4D's Realflow plug-in.
Chocolate sauce material
After the dynamics of the chocolate sauce are satisfied, the next step is to adjust the color and texture to make it closer to the real effect. Then I found a satisfactory lens for rendering. Finally, make the final adjustments in After Effects.
I put the output picture into After Effects, adjusted the color, filter, blur, etc. The following picture is the final effect.
