Animate an Isometric Building Transformation

Learn how to generate, edit, and animate a modular isometric building in Scenario - step by step- from a static structure to a dynamic transformation sequence.

Overview

This video workflow demonstrates how to create a controlled animation of an evolving isometric structure using Scenario’s creative suite: from initial generation to frame-by-frame transformation and final video output.

You’ll learn how to:

• Use a custom trained model (LoRA) to generate consistent versions of isometric buildings

• Inpaint structural changes across multiple frames, using the same LoRA

• Animate the transformation using a video model like PixVerse which supports first/last frame control

This technique is great for game assets, UI visualization, architectural design, and motion concepts in an isometric style.

Step 1: Generate a Base Structure

Start with a custom-trained LoRA model. In this case, this custom model outputs highly consistent blue/yellow isometric structures - perfect for modular designs.

• Use the “Generate“ tool and select your custom model.

• Prompt example: “isometric modular building, 5 floors, blue and yellow, clean lighting”

• Choose the most visually solid, readable 5-floor variant as your base image.

The use of a consistent LoRA ensures that proportions, lighting, and stylistic elements remain intact across multiple variations.

Step 2: Inpaint to Create Each Stage

Using the same LoRA model, create intermediate frames by progressively removing building floors.

1. Open the original image in Create > Retouch (AI Canvas).

2. Use the sketch & masking tools to cover (erase) one floor at a time, top-down.

3. Prompt with your original style (or leave blank) to polish the sketch

4. Generate and select the cleanest, most aligned version.

5. Repeat the process until you have all 4 stages:

   • 5 floors → 4 floors → 3 floors → 2 floors…

   

This iterative inpainting method ensures good structural alignment and visual continuity between each frame.

Step 3: Animate with PixVerse (First/Last Frame)

Now that you have your 4 static frames:

1. Open the Video tool and select PixVerse v4.5 or a model that support First/Last Frame mode to create controlled transitions.

2. Use the final image (floor N+1) as the starting frame, and an earlier image as the ending frame (floor N)

3. Prompt example: “The top blue floor of the building smoothly sinks into the lower floor and disappears, leaving only the bottom level with a grassy roof.”

4. Generate multiple sequences:

   1. 5 → 4 floors

   2. 4 → 3 floors

   3. 3 → 2 floors

Tip: For best results, this workflow starts by animating the collapse of the building—then simply reversing the video to show it being built. This approach produced smoother, more consistent transitions. PixVerse v4.5 outperformed other models in maintaining style consistency and delivering fluid motion throughout the sequence.

Tools Used

• Model Training: app.scenario.com/models/new

• Canvas (Retouch): app.scenario.com/canvas

• Video Generation: app.scenario.com/videos (PixVerse v4.5)

Tips & Recommendations

• Always use the same LoRA or video model throughout the entire process to maintain alignment.

• Inpainting from the top down is the simpler method (vs. bottom up)

• Use Prompt Agent (Prompt Spark) to auto-generate good, detailed video prompts.

Conclusion

With just three tools on Scenario, plus a style consistent model, you can go from a static isometric structure to a polished transformation sequence. Simply generate consistent frames in a guided process, then combine them into controlled video generation, frame-by-frame. Scenario gives you creative precision without the overhead of traditional animation workflows.

Whether you’re visualizing architectural logic, designing evolving game elements, or just exploring AI-driven motion, this workflow gives you full control over structure, style, and movement—every step of the way.
