This warning is only logged when using WebGL1 since you need power-of-two (POT) textures for mipmapping. There are a few options to avoid this message. You can disable mipmapping by:
- Set
Texture.minFilter
toTHREE.LinearFilter
- Set
Texture.generateMipmaps
tofalse
You can also use a WebGL 2 rendering context. Or you just ensure your image is POT.
