I started as a CG-artist in 2002 on small projects(visualizations for public departments) in 2004 I became 3d artist for Fanatic games studio(game models, rigging, optimization) which was my big career jump. Since then I've been producing game models and resources to many projects including Mafia(Illusion softworks), Overkill 3 (Craneballs studios), World of tanks(Wargaming). Lately I am concentrating on creating interior&exterior resources for visualizations and games for Unreal engine. less

Integrating ComfyUI AI-generated concepts into Houdini June 10, 2025, 2:12 a.m.
Hi everyone,
I’m currently building a pipeline where I generate concept images (vehicles, terrain, etc.) using ComfyUI (Stable Diffusion) and then feed them into Houdini for further processing – either as reference or for semi-automated geometry creation (through ML-enhanced Top Networks, depth maps, segmentation, etc.).
The idea is to have a semi-automatic flow:
Input prompt in ComfyUI → image generated
Houdini picks latest image from directory (using COP2 or TOPs)
(Later) Use ML to extract depth / structure → create procedural model or layout
Final output goes to Unreal Engine as asset/environment
🔧 I’m still in the early phase, so I’m experimenting with:
integrating ONNX inference directly inside Houdini
controlling generation from within Houdini (via Python)
proceduralizing based on 2D-to-3D logic or tagged structure
I'm wondering:
Has anyone built something similar (AI > Houdini > UE pipeline)?
What would you recommend for handling image-driven procedural generation?
Any tips for integrating ComfyUI output dynamically into COP2 / TOPs networks?
Here’s a screenshot of the current system in action (ComfyUI + Houdini preview):
Thanks a lot – I’d love to share more as this progresses!

How to set relative path to hou.hipfile.load March 3, 2020, 5:34 a.m.
Hi i want rund pdg from command line and i have two file, run.bat and automate.py
I need realtive path for hip file, i try it “$HIP/automate_process_easy_f3.hiplc” but this dont work
Please help me, thank you
run.bat
———–
SET hbatchDir=“C:\Program Files\Side Effects Software\Houdini 18.0.388\bin\”
SET “JOB=%ROOT%/Tools/pdg”
SET “HIP=%ROOT%/Tools/pdg”
%hbatchDir%hython.exe “%~dp0\scripts\automate.py”
automate.py
————
import hou
hou.hipFile.load(“C:Tools/pdg/automate_process_easy_f3.hiplc”)
import hqueue.houdini as hq
node = hq.getNode(“/obj/topnet1”)
disp_node = node.displayNode()
# blocking full cook of PDG
disp_node.executeGraph(False, True, False)
