Playing around with particles (not related to the LHC in any way)

Now for another lookie at our powerful arsenal of tools. This time I'm showing the Particle Editor, which is the app we use to do those nifty particle effects like fire, smoke and so on... you can get really nice stuff by using this thing.

Actually, the Particle Editor is nothing new in our toolset. Those who picked the HPL tools pack to make a map for Penumbra (or just for the sake of getting them) surely will have spotted a ParticleEditor.exe in there. You could create and control every aspect in a particle system with it.


Good ol' Particle Editor



It worked like this: you created a new Particle System, added at least one Particle Emitter, and then set these up with stuff like starting position, velocity, material, etc., which would be used by every particle created by each emitter.
When you are creating the Particle System, you sure need to check how it looks while you are at it, and this was the main flaw of the old Particle Editor: you could do a preview of the Particle System in the works, but the method implied saving it to a file and loading it on a viewer program. This was done automatically by the editor, so no sweat in there, but having to save to a file + loading the viewer is a rather blocking combo (meaning it makes you wait and only wait), which can last up to a few seconds.

Hey, wait a moment, this nutty is telling us to wait a few secs... what's the big deal? you might think... but if you spend a couple hours working with it, you will notice you will have to do tons of previews (even more when tweaking little details), which translate to a lot of time wasted in the end (not to mention the actual time spent checking the Particle System while it runs)... and also you will find it really annoying :P


Ahh, the old times.We spent a good time together,right? Wait, that was actually a LOT of time.



So for HPL2 we decided to make a "new" Particle Editor, which basically is the same editor for HPL1, but with a really übernice realtime preview. It still has some details that could be polished further, but it is quite nice to work with at the moment,and that's the important thing.

And now it's time to see this in action: behold while I make some strange effect in this video :)



Hope you liked it. Will get back to the Particle Editor at some point in the future. As always, you can voice your thoughts on this. I'll be happy to know those :)

F is for Femanx and Forlarren

Image
Back on July 1st, I blogged about the alien race known as the Femanx that caused onto Porphyra. It you didn't read it you can find the entry here . I believe I called them Femiax but I believe that name is closed content so in the final Races of Porphyra and Lands of Porphyra they will be address as Femanx. The other race that we have worked up for the letter F is the forlarren. Forlarren are the unfortunate offspring of demonic forces and nymphs. They are a very troubled race. We first worked with the folarren as a playable race back in Monstrous Races: The Second Wave and they turned out something like this. FORLARREN RACIAL TRAITS (0 RP) +2 Dexterity, +2 Wisdom, -2 Intelligence: Forlarren are graceful and intuitive, but possess only a low cunning that serves their cruelty. (2 RP) Fey: Forlarren are of the fey type. Forlarren possess no racial hit dice and exchange the features of their fey type for the class features of a PC or NPC class. (0 RP) Medium : Forlarren are Medi...

Megadungeons...

We need more megadungeons for the Pathfinder Roleplaying Game. There is Dungeon-A-Day, obviously and Paizo has just released Dungeons of Golarion (but its more of an overview). We need a classic megadungeon You know the kind... It doesn't have much in the way of plot or even make a lot of sense from level to level but it does have: - pathways to the darklands - prisons for eldritch demons - ancient ruins - lost civilizations - legendary weapons - unexplainable magic (lost magic) - mines - slave pits - elemental nodes - water-filled passages - mazes - one way doors (heck secret doors) - traps - haunted levels - classic monsters (ropers, trapper, mimics, otyughs [especially otyughs], owlbears) - dragons - monsters too big to have ever fit down those hallways. - artifacts A classic megadungeon with everything wrong and right about it. Who is with me!

Forest of Gora

The Forest of Gora sits between the kingdoms of Illaya and Grismor and serves as their border. Trade routes circle either side of the far stretching forest. Outposts can even be seen within sight of the forest, but none are ever directly next to it. Both kingdoms have learned nothing built near Gora will last the season without being ransacked or razed by those living in it. Both nations have tried on numerous occasions through the generations to lay claim to the land, either by force or in cooperation. Ill prepared for the guerrilla tactics of those that reside in it, they were held back every time. When the native occupants took out their building hostility on the private trade caravans that passed near their borders a quick, unofficial truce was quickly made with the impending threat of economic collapse a lack of trade would cause. Ecology Much of the flora and fauna of Gora is what one would expect from a temperate forest. A mix of broadleaf and evergreens provide a balance of wax...
