how to combine either shaders or materials

Questions & Answers
1

suppose, I want to achieve these two effects.
1)lighting
2) sinusoidally glow in some parts, defined by splat map.

I have access to these effects individually. as Unity standard shader and my custom shader. I do not know how to use both effect on the same object.

do you have to assign multiple materials? because i fear, if combined shaders is an option, I will lose control over the 2nd effect.,suppose, I want to achieve these effects on an object. 1) lighting. 2) object glowing sinusoidally at specific parts of the object, defined by a splat map.

I have access to these separately as unity pbr shader and my custom shader. but I do not know how to apply both on the same object. can I do this by creating two materials, add somehow blend them? or I can create a shader that can combine them? or any other solution?

You can use a Mesh Renderer component to apply multiple materials to one object. Each material can use each shader.
