I have a glTF 3D model of one of my products, and the colors are accurate using several online glTF viewers that I tried.
But Shopify's produces the image too bright, so the gray product looks white, and the black emblem looks gray.
Can the brightness/lighting of the 3D model viewer be adjusted, like it can for most other 3D model viewers that are found online?
I don't want to give customers an inaccurate depiction of what the product will look like.
If you aren't able to modify the Base Color channels on your 3D model yourself - I would recommend trying the levAR Shopify plugin to preview your glTF model - our viewer was custom built with color accuracy in mind - take a look at some models in our viewer here. We also support augmented reality on all mobile platforms!
