I updated a model from previous version and realized that the existing materials with the 32/48-bit texture files worked ok. But when I tried to add new materials with the same texture files, they were not working. Anyway, it was not my intent to use 48-bit file but it was just a texture file that I downloaded and was 48-bit CMYK. I converted to 24-bit RGB and all's well. I almost didn't pick this up and had to go back to the older model and 2022.1 version.
Just an observation.
Thanks!
