No Items Mapped (Custom Model Data: Floats and 3D Models)

[FurrO2]

Hi, i'm trying to use this mod but with my RP, i only got this red message :

I have both 3d and 2d items.

The command in the tchat is how i get them.

I Tried with the jar version in the desc + the latest build from 6hours ago but i have the same result. sadly

I'm using minecraft 1.21.6 fabric.
My Rp is made For 1.21.4 + versions only and i don't have any other errors except the red text in the tchat

Please try with the latest build of Rainbow, it should now support custom items making use of legacy custom model data numbers.

i got a crash after doing map action with 3d item :

crash-2025-07-20_12.04.23-client.txt

But for 2d, that seem to work.

Use Client Version 1.21.8 There are issue with crashing for older builds.

Hi, nothing seems to crash, but I got this error after running the /rainbow finish command:

report.txt

+when testing, i got this in my server :

[WARNING] [Geyser-BungeeCord] Not registering custom item definition (bedrock identifier=geyser_mc:item/keys/shrine_key): conflicts with another custom item definition with the same bedrock identifier

In the Rainbow folder, the pack is generated, but it seems to skip some of the 3D model items. I know 3D models can be buggy, so for now that's expected. But if you need any additional information (or my resource pack), just let me know! :)

geyser_mappings.json
And the mapping is incorrect , i have multiples items that have differents textures but the generated Geyser_mappings.json put the same texture for almost everyone
