You want to emit particles from the actual channel or just selected parts of an object

l got a piece of cloth (polygon object) who burn and l want it to only burn in a corner and use a map of white and black to emit particule like black will emit and white not....................

I dont know about particles but I think in texturing you can apply a map to a surfaces alpha gain to set what will get textured our not

In your emitter you need to enable "Enable Texture Rate" and check "emit from dark." Then, connect the map that you want to control the emission to this attribute (dragging it from Hypershade diretly onto the Enable Texture Rate attr would be easiest.

do you know how to take an animated file, map it as a bump map, and then match it to a turbulance field

dmeyer the Texture Rate stuff only works for nurbs surfaces and he's using polys.


Perhaps what you could do Hades is create a nurbs surface, wrap deformer it to your cloth, and then use the Texture Rate etc on that.
