Calder Moore builds a ruined tower and its surrounding landscape from simple geometry. He adds fine detail with displacement maps, renders in Octane and finishes the image in Photoshop. The result is a moody, greyscale scene of a stone tower that appears to have fallen apart. It is a displacement maps ruined tower image built as much for atmosphere as for detail.
The workflow uses four tools: Cinema 4D, ZBrush, Octane Render and Photoshop. A displacement map is a grayscale image that pushes a surface in or out to create relief without adding many polygons. Moore relies on displacement to keep his geometry light and his scene fast to work with, even when a displacement maps ruined tower setup involves thousands of small surface details.
Moore begins by collecting reference images for architecture, environment, lighting, composition and mood. He also prepares assets ahead of time. He builds a library of foliage scatter systems, which place many copies of a plant across a surface, and a set of materials he can reuse.
Moore builds his tower one piece at a time, and Inside Iron Man’s Arc Reactor: A Detailed 3D Breakdown takes a similar piece-by-piece look at a famous digital prop.
He breaks the project into small tasks. Moore writes out steps such as “make tower, break tower, make ground, detail ground,” so one large scene becomes about 20 manageable jobs. He says this keeps the work from feeling overwhelming. His approach also works as a practical 3D tutorial for anyone planning a large environment.
The scene was not planned as greyscale. Moore lowered the saturation during the lighting phase to check values. He liked the result and kept the image monochrome.
From thumbnail to blocked-in scene
Moore starts with a small thumbnail sketch. The sketch lets him test several compositions quickly and judge the flow of the scene. His goal was an epic tower that conveys lonely, forgotten, ancient power.
Next, he moves into Cinema 4D and blocks in the scene. He uses basic geometry and sculpting tools to build the main landform and the tower’s silhouette. He sets the camera position at this stage, because locking the shot early lets him refine everything else around it.
With the layout set, Moore adds detail to the tower. He stays with basic geometry and applies displacement textures for surface detail. Symmetry creates the archways, and radial cloners, tools that copy an object in a circular pattern, produce the pillars. He then uses radial cloning again to assemble the full tower.
Breaking the tower and shaping the ground
Moore damages the tower on purpose. He cuts the geometry with the knife tool and Voronoi fracture, which splits a mesh into irregular pieces. He then lasso-selects and deletes the sections he does not want. He follows the original sketch to keep the collapse readable.
He advises spending extra time on this step. A damaged structure looks convincing only when the breaks follow believable lines.
For the displacement maps ruined tower terrain, Moore exports the base geometry to ZBrush. There he sculpts the large shapes and keeps the surface detail light, because he adds more detail later. He creates quick UVs, which are flat coordinates that tell a texture where to sit on a surface. The UVs stop the displacement from producing artifacts, meaning visual errors. He then sends the mesh back to Cinema 4D.
Back in Cinema 4D, Moore builds the terrain shader. He uses a tileable photoscanned rock material from RD Textures, a library now part of Megascans. He raises the displacement scale, which adds complexity and depth to the basic sculpt. He then changes the scale and UV offset settings until the silhouette works.
The ground still looks too smooth after this pass. Moore duplicates the terrain, raises the copy along the Y axis and sculpts some areas down. He swaps the cliff material for a rocky ground material, also photoscanned. The render shows a blend between the two materials.
Texturing the displacement maps ruined tower and setting the light
For the tower, Moore creates a stone wall material with displacement. The displacement adds detail that the basic geometry lacked. To break up the repeating stone pattern, he adds a noise material that darkens some areas to create grime.
He then blends that grime with a gradient marble texture. The result puts more dirt near the base of the tower, where it would collect in real weather.
Moore works on lighting alongside the terrain and tower textures. He loads several HDRIs, which are high dynamic range images used as light sources, and compares them until one fits the mood. He then adjusts the composition and pushes light and shadow to create stronger contrast and clearer readability.
He also adds a cloud plane. Moore placed it to guide the eye through the composition.
Foliage comes last in the scene build. Moore uses Octane scatter systems set up with pine trees, shrubs, grass and other plants. He paints a vertex map onto the terrain, which is per-point data that tells each scatter system where to grow plants. For this scene he used pines, shrubs and grass.
For a look at where scene building is heading, Adobe’s Vision for AI-Driven Text-to-3D Worlds explores how whole environments could one day be generated from written prompts.
Rendering and finishing in Photoshop
Moore renders the heavy nature scene in sections. Smaller renders return results faster, so he can judge changes sooner. He tunes the render settings and optimises the scene to produce a large final image in less time.
After the last scene tweaks, he renders three passes. A Z depth pass records each object’s distance from the camera. A bloom pass captures glow, and an object ID pass creates a separate mask for each object so it can be selected in Photoshop.
In Photoshop, Moore starts by cleaning the render. He paints over displacement artifacts and any areas that read poorly, using basic brushes. He then creates the old photo look by adjusting levels and exposure, lifting the blacks, changing the background values and adding the bloom pass.
He paints over the base render in detail. The work removes geometry artifacts, smooths visual noise and adds brick texture to the tower’s silhouette. Moore also blurs the background parts of the tower slightly. The blur pushes the foreground forward and reduces flatness.
The final stage adds texture and grain. Moore places old photo and paper textures on layers set to vivid light and multiply, and adjusts the layer styles until the look suits the scene. He then makes a final pass with levels to balance the image with those textures. He duplicates and merges the layers, then adds grain, which removes the clean CG look.
Moore’s displacement maps ruined tower method keeps the 3D work simple and puts the character into small choices. A cut that looks like a collapse, a blur that lifts the foreground and a layer of grain each contribute to the final mood.

Frequently asked questions
What is a displacement map in 3D art?
A displacement map is a grayscale image that pushes a surface in or out to create relief. It adds surface detail without requiring many polygons, which keeps the geometry light and the scene fast to work with.
Which software tools are used in this displacement map workflow?
Calder Moore uses four tools: Cinema 4D, ZBrush, Octane Render and Photoshop. Cinema 4D handles blocking and terrain shading, ZBrush sculpts the terrain, Octane renders the image, and Photoshop finishes it.
How does Moore make the tower look damaged or collapsed?
Moore cuts the tower geometry with the knife tool and Voronoi fracture, then lasso-selects and deletes the sections he does not want. He follows his original sketch so the collapse stays readable, and he advises spending extra time on this step so the breaks follow believable lines.
Why is the ruined tower image greyscale instead of colored?
The scene was not originally planned as greyscale. Moore lowered the saturation during the lighting phase to check values, liked the result, and kept the image monochrome.
