Day 43

Today I continued with the ripple effect. Mr Steven showed me 2 files which describes what I wanted, how do I copy the fracture pieces onto the particles network simulation?

First he showed me a system which uses copy stamping:

What this does is he uses an expression to delete the pieces and then uses copy stamping to copy it onto the points.

It somehow worked, but there was this weird rotation that was going on. I emailed Mr Steven again, asking him if he knew what the problem was.

He told me that the pieces were copied to the velocity vector hence they rotate in a weird way.


He then showed me another method which was very very very much simpler to understand, and simpler to do.

At first, I couldn't even believe that it could be done this way.


Anyway, it worked perfectly. Mr Steven then asked me to test out the simulation with a grid size similar to my terrain, to determine roughly how many scatter points is needed. I tried a grid with 500 rows and columns. The cache file for the simulation amounted to 16 GB. And the simulation became super low. Maybe that was the limit.

After that, I went ahead into using my actual terrain. I realised that, given the severe unevenness of the terrain, I had a lot of trouble trying to group the particles for the ripple to throw it back down. I tried many methods, I tried using a bounding object as the bounds for the grouping, but it didn't really work that well, some particles still seep through resulting in crazy, stretching pieces. I tried setting that object that I am using for the bound to a collision object, and the problem with that was the bounce was super sensitive. Resulting in the particles flying all over the place.


Hence, I decided that the easiest solution for me to fix it was to flatten my entire terrain. Get rid of the mountains and stuffs. I will do it tonight.

Anyway, I would like to thank Mr Steven for the amount of help and help files he provided me during this past few days.

I guess I got to finish quick, If not there will not be anything new to show him tomorrow.

And there was another method of copying that I posted on odforce because I would like to know how to do it.

And I also finally came up with a production schedule. And after doing it, I realised that I still have a lot more work to do. Got to pull my socks up though.
