Character Sheet STUDIO is out !
Forgot to re-implement the facial expressions logic in yesterday's release! Please pull the latest version of ComfyUI-SpaceGremlin-Toolkit to get the fix. 😅
https://github.com/SpaceGremlinAI/ComfyUI-SpaceGremlin-Toolkit v1.3
Hi everyone,
Always with a Modular, Intuitive and Clean approach. Here is finally the New Version of the MICW - Fast Character Sheet Generator Using Reference Images STUDIO !
v2.1 (Studio) Note :
Brand new interface
Qwen 2.1 Image integration for post-processing and improved sheet quality
Dynamic Character Sheets (from 5 to 7 views/images)
Background removal powered by RMBG 2.0
Transparent PNG export for individual frames/assets

FAQ
Comments (26)
Could this be used to generate a simple character sheet, like, only 4 views (main face, front, side, back)?
Yes, but the workflow needs to be slightly modified.
You can also choose your camera angle and enable the "Export Individual Image" option to obtain a full-resolution image, then compose the sheet using Photoshop or other software.
Available Camera Angles:
"Full Body - Back"
"Full Body - Both Sides"
"Full Body - Left Profile"
"Full Body - Right Profile"
"Upper Body - 3/4 Front Left"
"Upper Body - 3/4 Front Right"
"Upper Body - 3/4 Back Left"
"Upper Body - 3/4 Back Right"
"Lower Body - 3/4 Front Left"
"Lower Body - 3/4 Front Right"
"Lower Body - 3/4 Back Left (may not work sometimes)"
"Lower Body - 3/4 Back Right (may not work sometimes)"
"Torso - Front (Shoulder to Belt)"
"Torso - Back (Shoulder to Belt)"
"Arms - Left Shoulder (Close-Up)"
"Arms - Right Shoulder (Close-Up)"
"Arms - Left Upper Arm"
"Arms - Right Upper Arm"
"Arms - Left Hand (Close-Up)"
"Arms - Right Hand (Close-Up)"
"Legs - Left Thigh (may not work sometimes)"
"Legs - Right Thigh (may not work sometimes)"
"Legs - Left Shin Profile"
"Legs - Right Shin Profile"
"Legs - Left Knee (Close-Up)"
"Legs - Right Knee (Close-Up)"
"Legs - Left Leg (Full)"
"Legs - Right Leg (Full)"
"Legs - Left Foot (Close-Up)"
"Legs - Right Foot (Close-Up)"
"Facial Expression - Neutral"
"Facial Expression - Angry"
"Facial Expression - Smiling"
@SpaceGremlin I see, good 'ol Photoshop never fails when needed, thanks for the info!
@ArttTaku I'm going to consider creating several types of forms for the next version. It's a good idea, anyway. PS: I said Photoshop, but I use Affinity ;)
@SpaceGremlin Thanks for considering it then... I've been learning that for most cases, less is more, so, these character sheets padded with too many images might not be ideal, and most generators can do fine just with 4 images in one single sheet, so, if this could be an option in an update of your workflow, then awesome.
@ArttTaku I have just published the latest version (rev3). It includes the compact sheet mode you requested, featuring five images from the angles of your choice.
@SpaceGremlin awesome, thanks so much!
Awesome WF, thank you so much for sharing it and continuing to develop it.
Thank you so much :)
Huge thanks for this workflow, excellent samples I've done. How do I know if its using RTX VSR or any of the denoise/deblur functions?
Hi, and thank a lot.
There’s no way to know for sure without comparing it yourself, but it works fine on my end—I ran all the tests before release. If you left the image size at 1 MP, disabling supersampling (which doesn’t really add much) together with enabling frame export will get you 2 MP images instead of 1 MP for a full-resolution result. The sheet is limited by the "Largest max size" option.
Been attempting to use this, but I've been having problems with the RTX Denoise/Deblur nodes - I installed the node pack, it's in my custom nodes folder (the node pack code seems very sparse, which surprised me), even ran the requirements text file, but for some reason the nodes won't activate or even appear in the Extensions Manager. What can I do to fix this issue? Did I install it in the wrong place?
From the little digging I've done, the RTX VSR PRO node pack somehow isn't recognizing my CUDA or my Nvidia-VFX install. Do I need to repair my CUDA or Nvidia-VFX somehow? And how would I do that if I do need to do that? What CUDA version do those node packs require?
@Ambrosia_AI
Hello,
Could you please provide me with the model of your graphics card?
I'll take a look on my end, because if even VSR isn't working, you have a problem with your NVIDIA drivers.
@SpaceGremlin NVidia RTX 4070 TI Super. By all rights it should be able to support this. I can see about updating my drivers though; I'm genning using a gaming PC, not a dedicated industrial PC, so my drivers are gaming optimized.
@Ambrosia_AI Try the Studio drivers, not the gaming drivers. I think it can be the problem
@SpaceGremlin Just installed the Studio Drivers, looks like that didn't do the trick - it's still asking for the old Comfy-UI-RTX-Nodes, and it's still claiming it doesn't see RTX Denoise or RTX Deblur despite those being in the custom nodes folder. Error I get for the VSR PRO:
Traceback (most recent call last):

@Ambrosia_AI
Sorry,
You are the first person to report this issue; since I am not the creator of these nodes, I cannot help you resolve it. You should report it on the nodes' GitHub repository; they might be able to help or have a solution.
In the meantime, disable the RTX node (bypass: Ctrl+B) and use the workflow without RTX upscaling.
Alternatively, remove RTX VSR Pro from your custom nodes and get the official version directly within Comfy. Both nodes share the same ID, so there is no need to swap them out.
If you encounter the same issues with Deblur and Denoise, bypass both nodes: they don't really offer any significant improvement.
hope it helps.
I have the same problems, the RTX nodes can't be installed, tried alot to fix this, no way.
@Jojo0Gojo Ok, wierd, can you provide me with the model of your graphics card, please ?
Which Series (5000, 4000, 3000) ?
Ambrosia have an 4000 series, I will create a new instance to try this, but I have an 5000 series.
Really love this workflow❤️ but It seems like I'm having some understanding problems with the new workflow. I can't find "Full body - Front" view. It's essential for me because the workflow itself creates a "new style" and I want the character looks the same on every image.
Also I'm wondering where is Shot 1 Frame? My Compact mode shot frame has only 5 views in total.
Hello,
This "Full Body - Front" view is always rendered and generated as Shot 1. That's why you can't find it in the enumeration list. Selecting it from the list is pointless.
When your sheet is generated, locate this view in the "Frames Preview with Index." You'll see that the first images are always "Full Body - Front."
You simply need to adjust the index of the target cell to indicate the index of this view's image in the "Sheet Composer / RTX Suit / Save Frames" window.
So in Compact Mode, Set the views as follows in the "Character Sheet Prompt Maker":
Shot 2 Frame (Compact Mode) -> Full Body - Back
Shot 3 Frame (Compact Mode) -> Full Body - Left Profile
Shot 4 Frame (Compact Mode) -> Full Body - Right Profile
Shot 5 Frame (Compact Mode) -> Any, it will not be used for sheet in this case
Shot 6 Frame (Compact Mode) -> Facial Expression - Neutral
And set indexes in "Sheet Composer / RTX Suit / Save Frames"
Cell 1 Image Index (Compact Mode) at ~120 (Face expression view)
Cell 2 Image Index (Compact Mode) at ~10 <-- This index corresponds to an index in the Full-body front view shots.
Cell 3 Image Index (Compact Mode) at ~31 (Full Body - Back view)
Cell 4 Image Index (Compact Mode) at ~53 (Full Body - Left Side view)
Cell 5 Image Index (Compact Mode) at ~78 (Full Body - Right Side view)
You must have on your final sheet :
- Face expression view
- Full Body - Front view
- Full Body - Back view
- Full Body - Left Side view
- Full Body - Right Side view
I hope this has been helpful.
@SpaceGremlin wow this helped a lot to also understand the Workflow. Its so powerful!!! Great job SpaceGremlin!
@Dannyone Thanks a lot ;)
I see that is quite useful for designers but i can use this also in H3 as a reference?
Yes, the sheet works on Minimax or others reference model
