Hey guys
Ive been working for the last couple of days on blowing the top half of a car off in houdini for a shot im working on. Im still not getting the exact look i want with the fire, but ill figure that out thursday in class. Heres my real problem:
I have a tracked scene in syntheyes 2008.
I need to bring it in so i can track the car to the area i want it. I went into syntheyes, exported my track as a Houdini Script, and then opened houdini to run the .cmd file. Problem is, no matter WHERE i put this script on my computer (including in the $HIP directory) I get the dreaded error sound. It says:
Error:
Source failed, <path> does not exist.
No matter where i put it. i have 3 drives running. Ones a portable (K) Ones a partition (S) and ones my C drive. ive placed the file on the S drive, on the K drive in the $HIP directory, and on my desktop ina folder, and every time i get this error.
I really need to get this done and rendering so i can composite… its due very soon.
Ive attached the script in case anyone wants to mess with it.

Ahh i see. Well youll be happy to know that with some finessing, the Veronoi fracture plan worked, and i now have a car with the top being blown off. Now to learn pyro fx to make the explosion/flames/smokes… *sigh* lol.
Thanks again for your help!

Hey thanks a lot for the help!
I just have one question:
Just so that i understand what I am doing and can apply it to other projects - in your expression: $CR>=0.2 I know (at least i think) that the $CR part of it is for color red to get the R of RGB, however i dont know what the >=0.2 Is doing in the expression, could you explain?

Hey guys, Im in the middle of a shot, and heres a quick overview of what i want to achieve, and the problem im having:
I want to have a car explode as somones walking away, specifically, the top, one tail light, and both mirrors are going to blow off. The plan (and correct me if this is a bad way to go about it) Is to group those items, turn them into RBD fractured objects and use Voronoi fractures to get chunks, then keyframe on some velocity and activate the sim at the desired time.
My problem:
Ive got my car geometry in, and my current tree on this car is as follows:
File sop
color sop (to turn everything black)
paint sop (to paint the desired areas pure red)
Now im trying to find some way to make the red ones a group of some sort so that i can select just that area and make it the RBD and apply a fracture.
I tried using a partition with the rule “$cd” but it didnt do anything noticeable. I am also trying to use a group by expression, but when i set it to by expression im not sure where to put the expression, or what expression exactly to use.
*I thought of trying group by bounding box, but because i want the mirrors and just one tail light to explode as well, and not certain areas between them and the rest of the explosion, id prefer to learn how to do it with a paint.
Im going to continue fooling around on my own while i eagerly wait for some help, and will post if i solve it.
Thanks!
