if using vector3 instead of texture is this ok?

If I use numeric parameters, including for Base Color instead of textures, will there be a decrease in performance for the material? Is it possible to generate a MipMap for textures more efficiently than numeric parameters when the camera is far from the target?

Only textures have mip maps. Constant colors don’t even need them because they’re just RGB values.

I understood about MipMap. But the parameter (vector3) slower than texture? I want to make a simple way to change the color of the tree.

V3 is much cheaper than a texture.
So if this is all you need, you are good to go.
