brandonY Posted February 9, 2006 Share Posted February 9, 2006 hi guys! well i got an idea for a intro for my demo reel ( aspiring VFX student) i wanted to have dirt blow away and reveal my name. I was thinking maybe a animated displacement map with a bunch of particles? im somewhat new to houdini as well. i am trying to grasp i3d shading right now. i thought maybe that i could intergrate that into it as well. thanks for your time guys! -B Quote Link to comment Share on other sites More sharing options...
michael Posted February 9, 2006 Share Posted February 9, 2006 you could try: making your name with a font SOP gererate particles on a grid animate the text 'up' create a group of particles based on the bounds of the text as it moves through the particles use a force to blow the grouped particles away etc Quote Link to comment Share on other sites More sharing options...

However, the challenge for you would be to get the attribute value to "stick" after the particles passed beyond the Attribute Transfer's search radius. You can then use this color attribute in comp to play with how the text is to be revealed in a separate pass. Hope that helped. Quote Link to comment Share on other sites More sharing options...

I've also done something like that in 3dsmax. But i just used a trick with opacity maps, and emiting particles from selected points. Quote Link to comment Share on other sites More sharing options...
michael Posted March 27, 2006 Share Posted March 27, 2006 nice... a few things that I noticed... the N at the end seems to be either emitting or deflecting particles in a strange way the 'background' particles seem a bit strange - like snow, and I'd remove them altogether for now as they tend to distract from the font particles... otherwise the movement feels good...

michael Posted March 28, 2006 Share Posted March 28, 2006 (edited) nice... the shadows of the particles are quite strong - but I like the movement oh lord.....I found the reel of a company I worked for in Calgary called Aurenya - now called New Machine....there is a shot of the Cheyenne logo animation (Bruce Willis' production company) around the middle of the reel that is an OK eg of the effect you're looking for... http://www.newmachinestudios.com/reel.html oh I think I should add that I didn't do the cheyenne logo...I just helped out on the comp Edited March 28, 2006 by arctor Quote Link to comment Share on other sites More sharing options...
deecue Posted March 28, 2006 Share Posted March 28, 2006 I think your effect is working, but the thing I'm concerned about is pushing it to the next level.. When working in motion graphics, i saw this exact way of bringing on a name/logo all the time and (unfortunately) they were able to acheive just as good of an effect as this with a simple 10 slider particle plugin in after effects.. the dust revealing logo thing to me feels like the post 2000 version of the lightning bolt scribing letters on to a wall of the 90's.. hopefully i'm not being to much of a downer and i'm definitely not saying to keep going with it.. just think about how you can push it further.. arctor's cheyenne example is a bit better imho by making it feel as if the letters are on some surface that is covered by dust and blowing away.. a little bit more realistic then the letters alone being revealed by dust coming off/out of them.. good stuff tho.. keep us posted..

keltuzar Posted March 28, 2006 Share Posted March 28, 2006 a suggestion: instead of trying so hard to make the name appear from the particles, why dont u try to emitting from the font and playing it backwards? heres is a gnomon link that will give u a hint and aid u http://www.gnomononline.com/written.php?tutorial_id=41 offcourse u need to then simply play it backwards....

deecue Posted March 28, 2006 Share Posted March 28, 2006 and i'm definitely not saying to keep going with it.. ahh crap.. i meant to say to *keep* going with it.. not to stop it.. oops.. sorry about that.. Quote Link to comment Share on other sites More sharing options...

masstapro Posted February 20, 2007 Share Posted February 20, 2007 Looking good. Try putting a little variation in the sand; different sizes and or weight. Also, try using multiple forces. Maybe some metaballs swirling from center to edges. Also, try to get the sand to kick up into the camera a little, just a few particles will help give it some depth. Looks great. ~Shawn Quote Link to comment Share on other sites More sharing options...
