thanks lecloneur and other contributors there are few example how to texture-based deform
field of particles.
As jannis example http://youtu.be/RE5y085wL0w shows it’s possible to specify desire area to emit particles there.
my question how to via texture define the emitter area?
Is it possible to get "clean"emitter without emitting full quad?
or it’s only possible via making rest of the full quad with alpha =0?
I’ve tried to RGBA split the cycle texture, but cant get rid of the full quad building
I would like to achieve opposite of patch attached = silhouette filled with particles
Thx in adv, dimi
@antokhio: i tried to insert keying(and inverted too) pass between different passes but it doesnt change much in particles emitting @everyoneishappy: i assume shader is adapted for the “displacementFX” - the field texture splited in two inputs. i will try to post the version with Dottore’s original. will see
Attached is the fake version of desire FX. @antokhio: keying in post, but full particles quad still emitted and that’s actually not what i want @everyoneishappy: I think the modified shader is OK for this case.
Generally I am not sure if it’s possible with this “Mesh Quad” approach to achieve specific area (defined by texture) emitting, not the full quad
