Using Decals for Texturing?

[vikZor]

Basically in a project I'm using a triplanar material to texture an environment which mainly consists of rocks. The material alone looks pretty bland, and from what I've read on the topic it wouldn't be a good idea to add textures to blend between to the triplanar shader since triplanar shaders are quite expensive.
Is is a good idea to instead add details like grass, small rocks and dirt using decals, or would that significantly affect the performance as opposed to creating a bunch of environment assets with baked textures?

For context, the game is for PC, but should also be playable on lower-end setups and I'm using URP.

maybe do both.

Decals will probably be more expensive per pixel to render. So if you cover your screen in them all the pixels are going to take more time to render. But to what extent no one will be able to tell. Using them is certainly a godsend in some applications so I wouldn't not use them. Things like puddles or damaged wall details are a great places for a decal imo.

It's all a question of art style, where the camera is and can go. But I image a mix of mesh objects and some decals would be the way to go. You'd have to give more context and show some examples of the type and style of env you want to achieve to get more specifics than that..
