View Full Version : Welding through a wall

I'm trying to acheive an animation where a few bank robbers break into a vault. First i would like to see some sparks and bright light flashing at a spot on the wall then it moves around kindof creating a red glow behind it, and then when it gets back to the begining, a loud thud will be heard, and the inside section will fall in onto the floor, showing the robbers.

I got the idea from blizzard starcraft, with the movie on the space station where the ghosts and a few marines are taking a bomb onto the station.

The way i was thinking of doing this was to use http://www.3dtotal.com/team/Tutoria...ng/cutting1.asp this basic concept then plug the cut out element into reactor (or keyframing) But i run into problems, the boolean doesn't show the cut starting to happen, so i thought that maybe i needed to use an initial object to make a hole that the pathdeform modifed object could start to cut through. But it still didn't work. Now i'm frustrated and wondering if any of you could help me out with my problem.

I whipped up a simple .max file of my problem if any of you want to take a looksy at it

Thanks

hi Murf_Miser,
I haven't looked at your scene but if i understand you correctly then this attatched file should help.

cheers,

Hey thanks for the reply

I was just curious, do you know if you can boolean that out without going from an edge?

Thanks

Hi Murf,
You mean having it start from halfway up the wall?
If that's the case then you could animate the position of the cutting opject over say the first 5 frames going from infront of the wall to through the wall. Once it was through then start it animating along the path.

cheers,
phil

Hey-

Yeah, thats what i tried to do, but it gets all "funky", and the mesh goes everywhere, but there is no hole. Thanks for the help again

Havent had time to look at the files.........but here's how I would approach it:

model the wall with and without the hole swap them at the point you want to break the plug out. Then apply reactor if necessary.

for the glowing cut: draw a spline around the outline of the hole and apply an animated map to it using the gradient map to reveal the glow/crack etc. more splines for more cracks.

if you want particle effects for the sparks/debris then use a point emitter on say a sphere which uses the spline as a path controller and then animates around the spline over time.

hope this helps.......this avoids using any animated booleans or shapemerges.
