Real time LCM guide take a Maya unfinish model to render


Hi I am ImpactFrames I put together this little guide to help you install live LCM a Realtime latent consistency repo to use stable diffusion interactively is a fun way to use SD like in the video


I am on the latest Nvidia Gamaing drivers without any issues

--I only have Windows10 so I will focus on that but if you have mac or linux you can ask, chatGPT or Bard to give you the translated commands if you need them--

be careful with the temperatures of your machine if you hear the fans go BRRRR stop close the program. I am not responsible for any damage cause, this is all bleeding edge experimental stuff and do it at your own risk, haven said that it works surprisingly stable

I will use command prompt if you use terminal the commands could be slighly different

I am using python 3.10.13 and works great

Pre requisites:

Okay first things first you are going to need a Nvidia GPU,

Intel Arc GPU or Apple M1/M2/M3 you can use this on Linux, Windows and Mac

a webcam

You Need Python 3.10 you can get it here

you need git

install firefox

install OBS

Now lets start :

The live LCM repo

Go to a location on your hard drive where you like to install it

You can create a folder

inside your hard drive C:\ and name it AI

something like C:\AI\

on the address bar type CMD to open command prompt

next copy and paste this into the command prompt and press enter

git clone

Now you should have a folder with the repo on the AI location on your computer

now we change directory inside Real-Time-Latent-Consistency-Model folder


cd Real-Time-Latent-Consistency-Model

you should see



python -m venv venv

to create a separate environment where all the dependencies will get installed

You should see the new folder venv was created inside the Real-Time-Latent-Consistency-Model directory

Now Type


this will activate the venv and you can see the new line start with (venv) indicating the venv is now active

now type pip install -r requirements.txt

this will install all the dependencies needed for the repo to work

including downloads for the models etc.. should take around 5 or 10 minutes depending on your internet speed

okay we can run it by typing uvicorn "app-img2img:app" --host --port 7862 --reload

instead of I will use

and you can use app-controlnet:app to get controlnet running too in addition there is app-txt2img

but it might add a little overhead

you can use the variables as needed

TIMEOUT=120 TORCH_COMPILE=True SAFETY_CHECKER=False uvicorn "app-img2img:app" --host --port 7860 --reload

TIMEOUT: limit user session timeout
SAFETY_CHECKER: disabled if you want NSFW filter off
MAX_QUEUE_SIZE: limit number of users on current app instance
TORCH_COMPILE: enable if you want to use torch compile for faster inference


uvicorn "app-controlnet:app" --host --port 7862 --reload

it will download some controlnet related models


hold ctrl and click on the link or type in your firefox address bar

okay here we are on realtime lcm you can press the advanced button to play with the settings, change the prompt

lets click start

select the camera I use snapcamera

okay the camera was lagging for some reason maybe because I used snapcamera instead of the webcam directly which adds more resource intensiveness to the mix but I have used it with almost no lag before

Let's do a little optimization

talking about it lets use img2img only withot the canny controlnet and optimize a little for the next test

open the python file and change line 52 to torch_dtype = torch.float16 instead of 32 to save a litle vram

I would recommend using this

TIMEOUT=120 TORCH_COMPILE=True SAFETY_CHECKER=False uvicorn "app-controlnet:app" --host --port 7862 --reload 

okay now lets move to using OBS virtual camera now

close the command prompt

open OBS

select the cog wheel beside start virtual camera button

select output type: source and outpute selection: Window Capture

on the sources select plus to create a window capture

and on the window select the program you want to use in my case I am using Maya but it works with any program even videogames. I open Maya and loaded one of my many unfinished 3d Models it will be a good use case for RTLCM to see how they would look if I ever finish it.

You can add a crop filter to manipulate the screen capture better

now let's go to the Real-Time-Latent-Consistency-Model directory and type CMD in the address bar

activate the venv


and type

TIMEOUT=120 TORCH_COMPILE=True SAFETY_CHECKER=False uvicorn "app-controlnet:app" --host --port 7862 --reload 

it should start streamming

now in obs click start virtual camera and go back to firefox and reload the page or type on the address bar again click start

select obs virtal camera and allow

I decided to go back to control net so I stoped it with ctrl + c

and started again with 
TIMEOUT=120 TORCH_COMPILE=True SAFETY_CHECKER=False uvicorn "app-controlnet:app" --host --port 7862 --reload 

if we see something we like we can also take an snapshot

and that's it hope you like this guide check my YT for more

diffuser 0.23.0 just came out and has support for LCM so we will ee similar functionality on A1111 and comfy I have a video on how to install the custom nodes for LCM in ComfyUI and also the LCM extension for A1111 so please look in my YT channel for more
