Texture UVW from just particular polygons

[stelees]

Hey there,

I have been messing around with inheriting the texture UVW but I can only get into work as the whole image applied to the emitter. Basically I have a plane with an image assigned to it and the particles only emit from certain polys. I want to ONLY have those parts of the image emit also to match where the fluid is coming from.

I was mucking around with the channels but then it all just stops.

Is this a thing or is it just the whole image from whatever particles are emitting.

Hmmm, can you tell us more? Maybe you are using the Polygon ID together with inheriting UVWs from the emitter?

Hey, I am limiting the emission to certain polygons, so I need to use a specific polygon ID? (or did I miss the point there).

[Svetlin.Nikolov]

Yup, polygon ID should be the way. So far the only suspicious thing in this setup is the plane - make sure it's shelled. Emitting from planes or using planes as obstacles is a no-no unless you want weird things to happen.

Can you show a screenshot of your source settings the way they are not working and how does your scene look, so we can reproduce it here?

Hello, just checked this case - and the polygonID solution with the "Inherit TexUVW from Geom" option from the source should work.
Instead of a plane, it's better to use a squashed cube, since geometry with open faces is unpredictable.
I'm attaching a basic example scene( polygonid_texuvw.zip )
