Shader compilation error occurs when using values sampled from texture for Customized UV1. No problem when connected to Customized UV0.
This problem compiles well if I change the value of Const to Parameter as a workaround.

1. Create a Material and Set the number of Customized UVs to 2 or more.

2. An error occurs when connecting the value of the sampled texture to CustomizedUV1.
