Error parsing emitter LibGDX ParticleEffects

I am using LibGDX 1.9.8 and attempting to add ParticleEffects made with the ParticleEditor.

I try to load a new effect with:

torchFX.load(Gdx.files.internal("effects/torch.p"), Gdx.files.internal("effects"));

But I am getting the below error

Exception in thread "LWJGL Application" java.lang.RuntimeException: Error parsing emitter: torch

I have already made sure to have the particle.png in the effects directory. I have tried it with my own custom particle effect as well as the ParticleEditor default. I have tried altering the SpawnShape to no avail. I have been coming to SO for answers for years and this is the first problem I couldn't solve by searching. I have also just updated all my jars to latest 1.9.8 and latest version of ParticleEditor. Any ideas?

I had a very similar issue, looking at an older file which worked and a newer file I noticed there were a number of entries in the newer one which was not present in the working file.

Namely the line;

independent: false

Deleting all instances on this seemed to do the trick for me.

I assume it's an updated feature not present in the current stable version of libgdx (1.9.8 at the time of writing). It may be available in the nightly version.

Looks like a property that's been added to the tweens on each individual property.

It would be useful if the older builds of the tools were more easily accessible.

I solved this by running ParticleEditor from the same gdx-tools.jar as my project uses. I assumed the runnable jar in the runnables folder in the libgdx repo was identical, but it is not. You must use the same tools.jar for both.
