Whee



Ok this is a tut for Gimp.

First, make a new image, and a new transparent layer.
Use the lasso tool to form a sort of weird shape.
Fill it with dark red, and shrink it by however much you want.
With each layer of selection shrinkage, fill it with a lighter color.
You can also make it get darker somewhere inside it like this.



Now, use Filter->Blur->Gaussian Blur...
Get it as blury as you please; use RLE thingy.
Now make two more transparent layers ontop of the fire layer.
Fill both of these layers with clouds (Filter->Render->Clouds->Solid noise...)
Make sure that detail is set to 15.
Also make sure that each layer has a different bunch of clouds.

Now, select the fire layer again.
Go to Filter->Map->Displace
Set the X Displacement to one of the cloud layers, and Y Displacement to the other. Don't use the same one, that'd be stupid.
Set the X and Y Displacement values to however much looks good.

Click OK and delete your two cloud layers. Tada!

Nice clear, and short tutorial there, Gimp users seem to have some neat tools at their disposal.

I wonder if you used a big image, with maybe 4x4 explosions, but animated, you could use this to create animated explosions. Like maybe copy that 16 times, and adjust each one, so it get's bigger, fades out, whatever - then do your filter tricks and make them into an animated explosion. Might work - I think that using a simple form, like the 70's wallpaper thing you start with, and adjusting that for the animation is a lot more sensible than trying to do it freehand (I've done that before, not pretty). I'll have to see what equivalent tools PSP/PS has, if any.

lmao

I got the idea to do it this way from a pic like this I made in PS. Except, instead of using a displacement map, I set the cloud layer to "Vivid Light". Although I did have to make a much rougher outline of the explosion.

Here's an animation
