Qt Quick 3D - 2021 - Weeks 5/6
Description
Have two materials where the only difference is in the referenced Textures, where one uses indexUV 1, the other 0. This will not render as expected: both models will use the same UV set, either 0 or 1, depending which material gets processed first. This is because the materials are deemed identical and the shader code is reused, which is incorrect.
