The project
An immersive video sequence featuring a contemporary building in a natural landscape. The challenge: keeping perfect structural consistency while taking advantage of the AI's aesthetic rendering.
Technical pipeline
01Houdini layout
The 3D scene locks the perspective, the architectural volumes and the camera move.

02Depth map and first frame
Export from Houdini of a depth pass to guide the generation, and of a high-fidelity reference image.

03LTX 2.3 and IC-LoRA
Video generation in ComfyUI with LTX 2.3. The IC-LoRA (Image-Conditioned LoRA) keeps fidelity to the first frame and the 3D layout throughout the animation.
