Hasta La Motion!

Hi, I’m trying to setup particular particles to bounce off a plane but I can’t get them to bounce off it. I have set it up as close as I can to Steve Wright’s tutorial but it doesn’t seem to work. I also can’t find his files anywhere to use as reference so I can see where I’m going wrong..

I have an emitter with an axis node, a card as a floor (the floor transform fields under the ‘physics’ tab was greyed out weirdly enough until I switched random things on and off randomly btw), it’s really all very basic but doesn’t want to work.

Would be great if somone could help me out please.

Thanks!

P.S I just reloaded my setup and now the expression I managed to write into the ‘floor transform’ is gone and all the expressions are gone. The green link arrow were still there so I deleted the floor card and now I’m stuck not being able to write that in again. Is this a bug or error in user?
