Adding WaiTex as an optional dependency lets Factorio run with both mods installed.

Perhaps I'm doing something wrong. Are you doing more than adding

"? WaiTex_Full >= 1.2.3"

to the info.json? Adding that much had no effect for me.

No, that's exactly what I did.
Edit: Whoops, forgot a comma before adding the WaiTex dependency and it wound up disabling the mod entirely.
Edit 2: Adding the dependency the other way around, WaiTex being dependent on SBGFX, lets Factorio load. Yes, I checked, both are on.

That's interesting, I expected that might end up disabling my colors but it doesn't. I don't understand what's going on yet but editing WaiTex does allow them both to work. Where the base game is low res only AND ShinyBob colors them, WaiTex's graphics get ignored but that's to be expected

Thank you very much.

Hopefully I can figure a more permanent fix soon.

EDIT - I hate that you are using low res graphics AND WaiTex in your screenshot

It was a fresh install of Factorio, I was wondering why the graphics were low res, thanks.

Replace: "dependencies": ["base >= 0.13.00"],
with: "dependencies": ["base >= 0.13.00",
"? ShinyBobGFX >= 0.15.7"],
In WaiTex's info.json file.
