    Hello. this looks really cool but - can we use it with a SDXL workflow, too? I suppose we need to parse the JSON output before feeding it to the CLIP Text Encoder, right? But, how? Thanks.

    hmmm,

    Yeah, and I can make that. Didn't think of that. Thee I buit this to plug in before Ideogram.

    I'll add a parser sometime in the next day or so

    @lonecatone23 That would be fantastic - and I also wonder if then we could run both this workflow and Omost in parallel and merge the results using a Conditioning (combine) node to feed into the CLIP Text Encoder. Overkill?

    @McBob67 why? There is a group of nodes already that does prompt building for SDXL. This is overkill as it is.

    @lonecatone23 Just toying with the idea of having this neat workflow compose the scene and Omost "direct" it and then merging the inputs...

    @McBob67 Did you see version 2? It gives you what you asked for

    McBob67Aug 28, 2026

    @lonecatone23 Oh you mean the parser? Outputting both json and "normal" prompt? I had actually put my nose to the grind after we commented about it and (with a little help from Gemini) I had come out with a small and very simple parser node myself - version 2 layout is much better though, so I guess I'll use that; it was a nice opportunity to tinker and learn, anyway. Thank you.
