CINEMA 4D • TUTORIAL + SCENE FILE
Tetris Tutorial.
Simple shapes. A satisfying project.
This Tetris tutorial for Cinema 4D takes you from constructing the bricks to creating a random brick-dropping animation with native tools. The finishing step is what makes the project useful: correcting individual bricks when the generated drop order does not look right.
The supplied scene includes an Xpresso-based MoGraph Weight Modifier. It lets you keyframe the weighting of individual elements by index number, holding back a brick until it is its turn to fall.

WATCH THE TUTORIAL
Piece by piece.
Build the scene.
The original tutorial starts with the brick shapes and builds a random dropping animation inside Cinema 4D. A recognizable design keeps the modeling approachable, while the drop sequence gives you a practical reason to refine the animation.
Watch the generated result before adding finishing details. The original post points out two problems: some bricks intersect others, and a top brick can arrive before the brick below it. The goal is a readable build, so the order of arrival matters as much as the individual shapes.
This is a tutorial for a Tetris-style animation, rather than a playable game. Follow the original video for the scene construction and initial motion, then use the modifier to address the exceptions.

BUILD THE WORKFLOW
One brick at a time.
Fix the drop order.
The scene’s MoGraph Weight Modifier was built with Xpresso to keyframe weights for individual elements using their index numbers. Instead of rebuilding the whole animation when one brick arrives early, the original approach holds that brick back until the timing works.
Identify the problem element, adjust its weighting over time, and check its arrival against the surrounding bricks. Review the frames before and after contact: a single finished frame can hide a collision or an awkward transition.
The original author tried to find a more automatic solution and chose this manual correction as the simplest workaround. It gives you targeted control; it does not turn the setup into an automatic collision solver.

FOLLOW THE BUILD
Build. Review.
Refine the timing.
- Open a working copy. Extract
AP_TetrisTut_SceneFile.c4dand save a separate version before changing the supplied scene. - Follow the original construction. Use the video to understand the bricks and the initial random dropping setup. Establish that starting point before making local corrections.
- Find the first bad arrival. Play through the sequence and note a brick that intersects another or reaches its place before the support below it.
- Target that element. Use its index with the included Weight Modifier, following the video’s controls, and keyframe the weighting to hold it back.
- Replay the surrounding frames. Check the corrected brick with its neighbors, then repeat only where another problem remains.
Keep the element arrangement consistent while making index-based corrections. If you reorganize the setup, recheck that the modifier still targets the intended brick.
GOOD TO KNOW
Tetris scene
questions.
What is in the download?
The archive contains AP_TetrisTut_SceneFile.c4d. The original tutorial describes the Xpresso Weight Modifier as part of that scene; there is no separate plugin installer in the archive.
Why not leave the initial random animation alone?
The original setup can let bricks intersect or arrive in the wrong order. Local weight changes let you correct those exceptions while keeping the broader animation.
Is the Weight Modifier an automatic collision fix?
No. The tutorial uses it to delay selected elements by keyframing their weighting. You still review the sequence and decide which bricks need attention.
How can I identify a clone’s index?
Maxon’s MoGraph Selection tag reference documents Display Indices for selected clones. Use the original video to connect that index to the supplied modifier’s controls.
Will the old scene behave identically in a newer release?
Current compatibility has not been verified. Open a copy and check the Xpresso setup, weights and playback before relying on it for a project. Maxon’s MoGraph Weightmap guide explains the native weighting concept; it is not a compatibility guarantee for this custom scene.
