Research direction

Start with the ovis_text_to_image template and compare its Nodes 2.0 subgraph configuration with the full workflow, using the attached reproduction and logs. Verify that changing the prompt in subgraph mode changes the generated content and style, while the existing full-workflow behavior still works.

Confirmation
  • I have confirmed this is a workflow template mistake
Template Name

ovis_text_to_image

Problem Description

In subgraph mode this template only generates kids with balloons. Like the prompt is not passed to it. In full workflow mode it works fine, however. Running ComfyUI under Ubuntu 24.04. See attachment, please.
