Short version: if you use Omniverse or other USD importing apps and updated to 10.02, please download Mineways 10.02 again.
I noticed after the release of 10.02 that the emission and metallic textures for JG-RTX were a bit odd. In particular, flowing lava got a lot darker. This comes from JG-RTX trying to make everyone happy: Bedrock, Java/Optifine, and Mineways. It's an asset nightmare, as SME and MER and LabPBR files fight to the death for dominance. Anyway, I've updated the JG-RTX emission and metallic textures in the 10.02 distribution.
I'm too busy to make this a new release (really, just these four texture files changed), so am quietly shoving them into 10.02 and calling it a day.
