Hey everyone

I thought I'd post a video which analyzes the bloom effect a bit in the game "Spyro - A Hero's Tail". I chose this game because it's different than your average bloom effect. It adds some kind of reflection as well. It's hard to describe, so just watch the video and see for yourself:



Here's a video with the render plain shifted upwards:



Attached is my current progress on recreating this. I have a problem with the bloom object shining through the floor even though it's behind it.

I believe it's a form of lens flare rather than part of the bloom effect.

Yeah, looks more like transparent plains being spun around on the videos. It would be much faster doing it that way. My other half loves those Spyro games...

It is some kind of flare yeah, but I do think it's part of the bloom effect because it shifted with the post processing plain when I added an offset to it (look at second video).

The first 3 games were amazing, game 4 was alright, game 5 (the one in the video) is better again, and all of the games after that sucked.

I would say it's quite annoying...

If anything, don't struggle implementing this in your own stuff.

Very few bugs can be called features but in that second video, that is definitely a bug and one hell of an annoying one. Something like that showing up which is obvious should not have been packaged and shipped as is.

Over the years I've found many tricks and tips on how to implement 'cheating' effects in games. It's really only lately I'm starting to understand a lot of them but I've never forgotten them.

A few years ago I tried 3D particles for the first time and realised that many cheating effects can be done using them. And now just recently I've read up on the Z buffering or something like that and found that a few more things can be done.

It's always interesting watching and reading up on stuff because one day something will click and you'll understand how they do it.

Unfortunately for my missus, I won't be writing a Spyro game for her anytime soon... (She keeps asking)

Hehe You get used to it after a while.

I shifted the plain up on purpose just to show that it's all being rendered to it.

It could be an unintentional "feature" as you describe it.

I would suggest it might be static cube map with alpha channel drawn after the background but before the characters. This is then added to the render target and a final bloom effect it added.

The same effect can be in DBpro I believe, but that would require three camera... 1 for the map, another with the map blacked out and the characters and cube map.
well thats my take.

And two I used to have this game, I was stuck on "Cloudly domain" the level that was in the same world as this but in the sky for a year.

This may sound odd but it looks a bit like syro is surrounded by a semi- transparant tube with internal light sources that are parented to spyro and when you rotate spyro they rotate at a different rate. The images arent too sharp for me on this laptop but thats it seems to look like there are 2 lens flares going on ..
One on the tube and if the light source is close enought to another object or scenery.
