if seen a cool effekt in a video:
There was some text and it exploded from the left to the right…
It looked like it was becomming smoke.
If seen a tutorial for that and i’ve got my text exploding and becomming some-like with the explode modifier and a particle system and in the tutorial the “left to right” effect was made with a blend texture mapped to the time of the particle system.
My problem is i’m using blender 2.5 (wich by the way looks way more profetional than 2.4) and i cant find where to map a texture to the particle system ???
for blender-2.55 the generation of particles in NOT RANDOM mode
is made according to the sorting of the faces in the mesh-data.
Now here is the trick:
If you generate a font-object with some text
and convert it to a mesh
what you need to do to set a particle-system to it -
then the conversion to mesh generates the mesh-data-faces from the last character to the first one
thats in writing-direction from the right to the left - backwards!
If you want to reverse this sorting,
try following:
in edit mode of the text-mesh select all faces …
and duplicta those (shift-D)
now watch how the particles are created …
from the old text-mesh-part, particles are created like befor
from right to left
but for the duplicated mesh-part … the particles appear after
the characters of the old text are done and
!!
for the new duplicated text the particles are created from left to right!
Reason: the sorting of the faces for the duplicated-mesh-part is reversed.
How to get rid of the first text-mesh-part …? Easy, delete it and you will
only have particles from the duplicated mesh-part and running from left
to right … like the writing direction … but still not in the chars! Only char
for char.
create a particle system as usual but turn its initial velocity and the gravity influence down to 0 and make start and end particle emition frames the first frame of your animation. This way all your particles will be there from the first frame on but will stay on the text. Then just blow your particles away in the direction and order you like with an animated force field with a huge falloff
you mean thats how it’s described in the tutorial? hehe cool that was just a guess
btw: nice smoke tutorials you’ve made just the explaination about the relation between the resolution and the particle count was a bit confusingly explained
made another test as i still was bored. Upped polycount and particlecound and changed forcefield settings.
@3Ditor Now it could come close to what you’ve intended. I hope you don’t mind that I spam your thread with my tests. If you do, i’ll remove them and open an own thread.
Yeah, that’s the core step most people seem to long for. There’s of course a lot more in the tut that should help solve most problems one might encounter. Like text-retopo, problems with the normals etc. etc. etc.
The easy way to sort faces is to just use an orthographic view, like left, right or top. Then, with the mesh in edit mode, use CTRL-F and choose Sort Face. From the secondary menu choose “View Axis”. This will sort the faces from the front of the view to the back of the view.
Using this technique, you can control how faces build (it works with the build modifier too) or explode.
ahh, thanx! I missed this function to do face-sorting of the mesh.
But i still think to do a face-copy to reverse the sorting is a nice thing
if you have a textbox with multiple textlines and want a particle-system
in the order of the writing of this text like first testline, second textline,
third textline …
you have to make the “wind” small and you have to animate the position -
i bet you have not used the “wind”-option inside the particle-system, this acts on the whole particle system.
Create an empty and set “wind” for it, then you can move this “ventilator” around … make the wind-energy small and move it under the first character … then only the particles there should be blown away …
i used the “use maximum” option in the force field settings. With that you can specify exactly in which radius the field shall influence the simulation.
i have a first result with Atom’s sort face method …
i guess the result is fine the good thing about this mehtod is that you havent used any force fields or something for the actual effect and you are more flexible
… i dont know why but i cant post any links :S
just go to youtube and add this to the url: /watch?v=jTYXbP-NFgc
and i would know how to set up my forcefields
