There was a little plugin from lamaison a while back which enabled you to use image sequences as weightmaps (if I remember correctly). And if I also remember correctly that one was only availble for Windows.
So...
it would be awesome if it was possible to use a scalar image as a weightmap so that I could animated it and emit particles from that.

Get Point Texture Map Color -> color to rgba -> set data on the weightmap
could work?

Hi All,
There was a little plugin from lamaison a while back which enabled you to use image sequences as weightmaps (if I remember correctly). And if I also remember correctly that one was only availble for Windows.
So...
it would be awesome if it was possible to use a scalar image as a weightmap so that I could animated it and emit particles from that.
The problem with using a texture is that you need an insane amount of polygons for have some detail. It's the main problem with using weightmaps. So I was wondering if there is a way around it. It would be better if it actually could do a texture lookup and see what value the pixel has. Somehow it seems possible, I just don't know where to begin. Or if the ICE tree would be too heavy to calculate.
So a scalar image on a lowres geometry would be the ideal solution.

Should be able to use it to do what you need, though it could be quite heavy. I'd prob just get a local subdivide duplicate mesh with a weightmap on it as a hacky quickfix!

You could still check a TextureMap and then delete at a certain value on Emit - no need to use weightmaps at all then. The only problem is that you'd have to overload the emittion rate to take into account the fact that you'd be deleting a number of them.

Yep, that's easily possible. Just create a texturemap on an object, select a projection and an image for the texturemap to use and then build the icetree shown in the image on your object.

If you use a texture map property - you can bring this into the ICE tree and using closest location of similar - read the value - this is how we are getting texture map colour onto strand fur and feathers!
