So with this meeting I was having issues with the model. I was getting a bit upset with myself because Diana seemed to have progressed nicely with the smoke simulations but the car was getting more and more complicated. I was getting very frustrated with myself. I was using the rbd constraints as the simulation tool because I was following what Medhi had done in the smashed building tutorial.
As you can see the constrains were working with the glass. The white lines show the constraints. But my issue was the the whole of the glass was just falling out of metal frame. It wasn’t holding its shape like my references.
When I change the collisions from a moving sphere to just using the ground/gravity. I can see that glass would never respond this way. There needs to be an initial hold before there is a breakdown.
Here is the workflow I set up for the glass. I thought that if there was more points that it would be more realistic. Unfortunately, more scatter points just makes it slower and didn’t resolve my issue.
I then thought that if I fractured the glass differently to look like glass then it would make more sense. However, it didn’t make much sense as car glass doesn’t shatter like normal.
Shattered glass references:
Meeting with Medhi
- assemble has more options than connectivity node
- volumes to collide rigid bodies – just use sphere
- same names throughout – don’t create name
- come pieces don’t have a thickness – use poly extrude
- fracture first the poly extrude
- clean each
I was having more issues again and turns out I was making a new name in my workflow top many times so that the system couldn’t identify the pieces. I was getting very confused but the assemble node seemed to assemble everything back together again. I think I needed to go away and read more about the assemble and connectivity node. This week was definitely the hardest for me as I felt so behind compared to Diana and I wasn’t seeming to understand how to resolve me issues. Felt like I kept making the same mistake and wasn’t good enough to continue. I kind of lost the enjoyment at the stage. Hopefully I get it back.
