    1. Jace

      All right, so let's take a look, huh?

      Yeah.

      What are you showing us first?

      I've

    2. Simon

      prepared some things, okay?

      I'm going to show you an explosion from the Noblisk detonator.

    3. Jace

      Everyone loves

    4. Simon

      them.

      Yes, everybody loves them.

      Me too.

      So this is how it looks like this if I play it.

      That's cool.

      Yeah, so this is how it looks for me like when I'm working with it.

      So I have all these things here is different emitters that spawn sprites, particle sprites, and you can like add textures to them or color

    5. Jace

      and

    6. Simon

      change all these parameters.

      But we can break it down or something.

      Yeah,

    7. Jace

      sure, sure, sure.

      If you can

    8. Simon

      see this, this is like if you can see the debris flying around.

      And then to this, I add sparks.

      You add it in steps, right?

      So I have sparks.

    9. Jace

      Sparks and debris.

    10. Simon

      Sparks and debris so far.

      And you can't really see this, but this is a light, so if it were closer to the ground, it would lit up the ground as well.

    11. Jace

      Okay.

    12. Simon

      And then we have a dome, so it gives this thing around there.

      You can't really see it if you look at the effects all together, but it's there, and it

    13. Jace

      makes...

      It helps just make the whole thing come together, I

    14. Simon

      guess.

      And then I'm adding some fire.

      This is some fire to it.

      And this is like a fire.

      Let's see if I can show you this as well.

      It could be fun.

      It looks like this.

      It's a sprite sheet, right?

      Oh, yeah, yeah, yeah.

      And these sprite sheets I make in another software called Houdini.

      So I just make a simulation of it and then make a texture of it.

    15. Jace

      And what is a sprite sheet?

    16. Simon

      I can show you again.

      I can do this.

    17. Jace

      Boom, this.

      OK.

      So what is the purpose of it?

    18. Simon

      So this is animation.

      So it's like rendered animation.

      So the sprite on the particle system, it will play through this animation from this part.

      So we just go like this

    19. Jace

      over this lifetime.

      Right, so that's every frame of the animation.

      Yeah, exactly.

    20. Cool.

    21. Simon

      So I had that, but I just bumped up the color so you can't see the smoke in it.

      And it does this thing.

      And then I added...

      So the fire spawns another fire.

      So it has even more.

      Like that.

      And then you just add some smoke to it.

      So it's like this.

      And together with sound and the camera shake, it's really cool.

      It helps sell the effect even more.

    22. Jace

      Right.

      That's dope.

      It's dynamic.

      It's not the same every time.

    23. Simon

      No, exactly.

      It has different velocity.

      It has a chance to spawn in a different area within a sphere or something like that.

      It's different every time.

      You can see if I just click it.

      yeah cool yeah so that's that's one effect i guess that this is what i think most people think of when they think about vfx like explosions and stuff like that

    24. Jace

      yeah

    25. Simon

      yeah but there's there's one thing that i want to show you that many people don't think about maybe so that's like ambient effects so in in dune desert for example
