What's the best way to have an engraving displacement that doesn't project through to the other side of an object?

Say I have a teapot and I want to engrave a logo on one side, but don't want it top appear on the other side.

I never have felt like we got that one sorted, unless I'm missing something?

Map the other side separately? Unless I'm missing something about what you need.

I don't think the displacement map can be isolated to material IDs though can it?

I think AJ meaned you should uv everything and put the logo in photoshop just where you want to have it.

I don't think the displacement map can be isolated to material IDs though can it?

You can actually do that using the MultiSubTex.
With that you can use the decal (map channel) method where you don't need to uv it and just use a UVW map in planar mode.

Does that actually stop it from appearing on the other side of the teapot though? Because it's going off the dispplacement modifier, which, as far as I can see cannot be isolated to material IDs... what does the other side of your teapot look like?

I'm not turning it off.
But I replace the color for the other side with mid gray so nothing happens there.
Here is the scene. Logo.zip

Edit: I repaced the scene, the first one was set to 2d displacement which doesn't work. 3d does.

Strange... I should have set the Texture chan parameter in the DisplacementMod to two.
Since thats the channel for the map and the UVW Map modifier but it works even when it's set to 1.
I'm wondering why...

On a side note: I find Texture chan distracting since its called Map channel all across 3ds max.
Or is it something else? The help reads like it's the Map channel though. Now I'm confused.

Texture chan – The UVW channel that will be used for displacement mapping. This must match the texture channel specified in the texture map itself, if it uses explicit UVW mapping. This is ignored if the Use object mtl option is enabled.
