So I've wanting to do http://imageshack.us/a/img842/4262/7d3n.png and created a teary eye using a Decal Map

Seeing as up to 4 Deal maps can be used how do I get the Decal maps to rotate so I can show the tear rolling down her cheek?

I see I can attach it to a timer but unsure how to do so

As far as I know, UVs can only be translated, not rotated. If I am wrong, I'd love to learn more.

Agreed. Perhaps "4 Deal maps" meant that she plans to use 4 detail maps, with each one having the tear at a lower point on the texture to simulate a "rotation." Which sounds possible, but I don't see what a little tear meshes couldn't be done by adding a tear to the head meshes the same way the jaw opens for talking animates.

But I'm just a spammer - so I'm probably not right - I don't know how head meshes work - honestly.

Well you are a spammer - but today you are bang on

Yes - I meant there are 4 Decal Maps - a Decal Map covers only a specific area of a mesh - I want the tear to track down her face - when I say rotate I meant that first Decal Map 0 would show then Decal Map 1 and so on finally coming back to Decal Map 0

In Nifskope there's a line on the Decal Map Texture that says: Controller and the next column it says Ref and the next column it says None

That made me think that if I could get the TimeController to work then I could set a number of seconds for each map to show

In the head mesh I can't see how to add a NiTimeController though let alone work out how it should run

I've noticed with the Decal Map there really isn't a lot I can do with it - I'd love to add gloss to it but that seems to be controlled by the NiMaterialProperty - which unfortunately adds glossiness to the whole head mesh

Wolli an animated Tear wounds great - however I think it can be done by animated textures alone - I just need to find some I can reverse engineer to understand how they work
