Hi guys,
Can you please help me create a simple scene in which particles will emit from texture?
I tried the approach with adding point sop to my geometry and adding color with expression “pic(”path_to_image“,$MAPU,$MAPV,D_CVAL)”
and grouping the points and emitting only from that group,and it works.
But the problem with this approach is that my picture is as detailed as my mesh is subdivided.And I don't want to end up with a high resolution mesh only to be able to emit particles from texture.
Is there a different approach?
I would like to be able to create a nurbs grid,assign a texture and make particles emit only by reading texture information value,r,g,b,luminance for every point on surface like in maya?
Thanx

ok the guys from odforce showed me the trick
i should put the same expression in the birth probability field,and it works

hey! nosferatu!

what's the answer?

thanks.
