MAKING TRI PLANAR TEXTURES FOR THE ROCKS FOR THE 3D PROJECT
this is the final result of the tri-planar projection
MATERIAL NODE FOR THE TRI PLANAR TEXTURE
the following is the final node for the tri-planar textures

I made a material function where I made the 6 texture parameters and named them accordingly so we could add the required texture
we can see all the parameters where we can change roughness, blending smoothness and we can also change if we want to make a texture just using 3 planes
