Felox/workflow-car-3d

Introduction

A comfyui workflow based on klein 9b and LTX 2.3 to render a shot based on a clay 3D render. Shown example work with a car shot render.

The workflow:

• generate a first frame and blend the car.
• generate a first LTX 2.3 pass with the IC-Lora
• generate a second pass with a injection of the 3d render. It allows to have a more accurate version of the car models.

Model needed

Base model

• Klein 9b
• LTX 2.3

Lora

• LTX-2.3-3DREAL-LoRA
• Fusion Lora

Comfyui custom node

• KJN nodes
• LTX nodes
• Video Helper Suite
• RES4LYF (Sampler on second pass, not necessary)
• NKD sigma curves (Adjust Sigma on second pass, not necessary)
