I just figured out how to scale up objects, but now my explosions look sissy and lame and lame and sissy. Is there a way to make them... you know... bigger?

Edit them with Particle Editor. Look it up in the FAQ.

Hmm... I got the particle editor working, but the effects are all squares!

Check this topic.

Someone should put that in the all you need to know thread under particle editor.

Funny, I thought it was

When you've got PE going:

1) Pick the emitter you want to change
2) Go to Transformer --> Size
3) Mess with the scale and lifetime; you have to make the scale bigger but make the lifetime longer so that the effect doesn't move too fast

That's how it is for most effects anyways. Which one(s) are you changing?

the timebomb effect. I do exactly that but when I load the game nothing is different...

That's probably because you didn't save it as a custom .fx, or is still referencing the shipped explosion effect in your .odf.

And the new effect must be in your sides effects folder.
