Well, having reached terminal desperation, I am now attempting to update my personal franken-pack to 1.16, So far I've got Soul Lanterns updated nicely. Moving on to soul torches, however, i've run into a problem I can't figure out how to solve.
As you can see there is still a vanilla particle in my cyan torch flame. How does one disable this? I've been digging around in the resource pack to see how R3dCraft did it for normal torches... but I haven't found it and Google has been rather unhelpful.
Thanks Katja. You put me on the right track. Turns out the existing resource pack does still have particles for normal torches... but they are difficult to spot because they blend well with the flame animation on the torch itself. I simply copied that to the right filename and recolored it with a cyan overlay. Works like a charm. Thanks again.
