Is that the result you are looking for? https://jsfiddle.net/sem1ryva/1/

You have copied code from https://threejs.org/examples/webgpu_tsl_angular_slicing which is unfortunately not compatible to MRT since the slice material sets a custom output node. I think the same result can be achieved by setting colorNode instead.

@sunag Is the original demo of the OP the expected result? Meaning should the MRT setting be ignored with custom output nodes?
