Having no attenuation distance set in the project/code, defaults to infitity. This property then cannot be set in GLTF file and automatically sets to NULL. NULL property cannot be read by various softwares, for example - Blender 4 - > onwards. By adding check if distance is !== infinity we either send that parameter if its set, or don't send it if its default.

Fixed #29034
Description
Having no
material.attenuationDistanceset in the material, defaults to+Infitity.+Infititycannot explicitilly be set in GLTF file and automatically is set to NULL by Three.js. NULL property is not allowed in JSON and makes the file invalid. It then cannot be read by various softwares, for example - Blender 4 - > onwards.According to KHR_materials_volume in order to convey infinity, the value should be ommited. We propose adding check if the
material.attenuationDistance !== Infinitywe either send that parameter if its set, or don't send it if its default.
