How to Convert StandardMaterial3D to VisualShader?

i wanted to create a snowy-rocky mountain so through visual shader i used mix-vec3 along with a noise texture, one snow and rock texture. but when i apply it on my mountain mesh i does not work but it works on a plane meshinstance3d.

i guess its because it not triplinar but there no node for triplinar in vertex section for visual shader

help.

You can only convert StandardMaterial3D to shader scripts.

There is a Triplanar node for visual shaders, as it’s dealing with texturing fragments it must be in the fragment shader.

not working this is the setup
