The Explosion FX Deformer.
The Explosion FX Deformer is one of those deformers that sounds like it will be way cooler than it actually is. I don’t want to give it a bad name and turn you away from it before you give it a shot because you really can do some interesting and cool things with it and depending on what you’re trying to do. Although based off the name of it you’re probably expecting to realistically blow up your models and if you are you’re going to have a bad time with this deformer. If you want to just blow crap up I would suggest checking out Nitro4D’s free Thrausi plugin, or if you want something better his donationware (trust me, it’s worth it) NitroBlast plugin.
Here is how the Explosion FX Deformer is set up:
One of the first thing that you’ll probably notice when you use the Explosion FX deformer are the three colored spheres that it makes: Red, Green, and Blue. Each of these spheres represent the three main options that you use. The Green sphere is the time property:
The time property is probably the most important one in the whole deformer. Moving the time slider is what will blow up your object, the lower the percentage the less it is exploded, the higher the more it’s exploded. Pretty simple.
The Red sphere is the Blast Range. I think the name blast range is a little misleading – If you make the blast range really small your object is still going to explode. Basically how it works is anything outside of the Blast Range is not sped up by the blast. Anything inside the Blast Range will speed up and can keep traveling outside of the Blast Range. So really the Blast Range is what explodes out.
The Blue sphere is the Gravity. Anything inside of the Blue sphere will be affected by the gravity options that you set. What can get weird and frustrating about this is that anything inside of the Red Blast Range will be affected by gravity regardless of it being in the Blue sphere or not.
There are a lot of options in this deformer, it would be a lot to list all of them here. But honestly, most of these are very self explanatory. If there is something you can’t figure out leave us a comment and we will help you figure it out. So what I’m going to do is just go over the options that I think might need a little explaining.
Cluster Type - Cluster Type tells the deformer how clusters of polygons are connected together – if at all.
- Polygons - Each individual polygon is separated, none of them will cluster together.
- Automatic - Each cluster is put together with a random number of polygons. You can change that number by changing the Min Polys and Max Polys option.
- Use Selection Tags - Polygons that you have in your attached selection tag will form a cluster. Any polygons you don’t have in your selection tag will not cluster at all but still explode out. If you click on “Fix Unselected” only your selection will cluster and explode out, everything else will stay right where it is.
- Selections + Polys - This is a mix between Use Selection Tags and Automatic, your selections will cluster and anything unselected will cluster automatically.
