If you cannot get the node ComfyUI-PainterI2V to work. Look for ComfyUI-PainterLTXV2 on GitHub. This solved the issue. The one in ComfyUI Manager doesn't work and despite going directly to the GitHub page didn't fix it either
Установи их через git а не через manager, всё запустится
After resolving the Node issue now I get this error message "can't access property "workflow", res is undefined".
В workflow есть заметка
Low Vram : 640 x 360 -> Final Video after Upscale : 1280 x 720 (720p HD)
Mid Vram : 960 x 512 -> Final Video after Upscale : 1080 x 1024 (Full HD)
High Vram : 1280 x 704 -> Final Video after Upscale : 2560 x 1408 (2K)
V. High Vram : 1920 x 1024 -> Final Video after Upscale : 3840 x 2048 (4K)
У меня вопрос, V. High Vram это на какую видеокарту? У меня на Mid Vram часто OOM выпадает
При таких вопросах, для начала, принято указывать свою модель видеокарты.
А у чела там вполне может быть какой то ртх6000 на 96гб и ему редко ведомо понятие хай врам.
