When using RTX with texture packs in Minecraft, most light-emitting blocks fail to glow, except for torches. Additionally, some areas appear excessively dark and require brightness adjustments, but this cannot be changed within the settings. This suggests a rendering compatibility issue between RTX and emissive properties, affecting both lighting effects and overall visibility in certain regions.

Lo mismo me esta pasando, ya probe los Prizma y los Vanilla RTX y ninguno muestra correctamente la luz de los bloques que emiten luz, es un error del juego que igual me comenzo en la 1.21.9
I’ll say this again, but all forms of PBR material textures are broken, not just emissive. Metallic, roughness, normal maps and height maps all don’t work.

[media]Same problem. Why couldn’t Mojang just work with the already existing material systems with RTX but instead rewrote it again and says they’ll never update RTX again.
Such a problem Mojang stopped support because of the new graphics mode, I doubt they will fix it, only a rollback to previous versions will help.
I am successfully using a workaround, that is a combination of suggestions found in various forums. First, move your RTX texture pack to the global resources folder, instead of the resources folder in your world. Then, from the main Minecraft menu, go to settings, video, scroll down, and toggle “Allow in game graphics mode switching” to off. Don't worry if the graphics mode is set to Fancy. Go back to the main menu. Click setting again and toggle “Allow in game graphics settings” to on. Go back to the main menu again, click play, and open your world. Minecraft should detect the RTX pack, and set the graphics mode to RTX; glowing blocks should be working correctly. Unfortunately, you'll need to do this every time you open your world. If you're using an RTX pack from the Minecraft Store, you won't be able to move it, and the rest of the process may or may not work for you. I haven't tested it. I'm using a Patreon supported pack, and this works for me. Your mileage may vary, but it's worth a try.
Using Global/local resource packs such as actions and stuff above or below the RTX pack disables the PBR textures once again and I haven’t seen a solution to fix it. The resource packs and RTX both do load but no reflections on blocks nor light emitting blocks. Its one or the other, or beg to Mojang like I’m probably gonna end up doing if no change
Same here. Torches and lanterns work as expected. But, light emitting blocks, such as glowstone, sea lanterns, redstone lamps, etc., do not emit light in RTX. Redstone lamps, for instance, do switch on and off, they are simply no longer emitting light. They do emit light in any other graphics mode.
This started for me with 1.21.90. I have reinstalled Minecraft, reinstalled video drivers, cleared the NVIDIA cache, cleared the DirectX shader cache. No change. This is true for every RTX enabled pack or map I have tried.
Something seems to have changed with the way light emitting blocks are coded, since Vibrant Visuals, that is breaking them in RTX.
