a nice cavern filled with lava

Cool Bongo can you make it a Draw Tile eg: lava_floor_tile, that way you don't have to put so many objects on the map Just asking that's all.

[minmay]

This will be very bad for performance since you are making an additional light on every tile. I'd prefer to place fewer, larger lights manually.

[Eleven Warrior]

Yes I agree with you Minmay. I just made the Lava Floor Tile just then and on my system no issues, but on a lower performing PC it would be very bad

[Batty]

It does look good but I put down 6 of these tiles and lost 10fps so uuuhh I'd go easy on them.

[juho]

Shadows could be turned off to help performance. We usually didn't have shadows on on similar type of assets in the main game.

Cool!!!

[bongobeat]

glad you like it.
I suppose that this can eat a lot of ressource on the map, specially if you fill an entire map.
(need to try)
I don't know if it will be better to make a full new lava floor, as I'm using the wallfire particle which is very cool, but maybe it is not optimized for this?
anyway, it runs without lag with a geforce gtx 660 with full details. But I don't wanna know how it will act on my old computer

For safety I have disabled the light and the particle of the fire_emitter on the central lava square (by unchecking the particle and the light in the editor). This works well and you don't notice that they are missing.
shadows is still on.
Maybe the particles of the dungeon fire pit is not necessary as the wall_fire looks great without anymore particles.

I forgot about the chasm: you need to use the falling script that kill the party, if you go through lava.

Or just put invisible wall

Really nice! I was wondering what would be the best way. Now just add an invisible platform and make the golem walk over it >:D

well this can be cool, if you add some special effect when the golem walk.
actually it's a little strange, because he walks on the fire, but the fire looks like "inert"
there is a problem with the golem height too, it is too big for this area. When he moves, his head or his arm go trough the ceiling

Cool Bongo can you make it a Draw Tile eg: lava_floor_tile, that way you don't have to put so many objects on the map Just asking that's all.

well I dont know how to do that actually:
I have tried to put the chasm definition and the fire emitter definition in the same object, but as there is 2 models, only one model will be used.
The problem is, how to add the wall_fire model in a object and transform it as a particle.

This looks great! Ultima Underworld memories arise...

Beautiful!

Hi!

I've been playing with lava recently, and I would like to know what you think about it :

SpoilerShow

Another test with range = 10 and brightness = 4 for thre light source of lava_effects, which do you prefer ?

SpoilerShow

The idea was to combine the fire emitter with an animated water mesh. I thought the wall_fire model alone made tiles too obvious, and lacked some animation.

The lava definitions :

Just place some water tiles (elevation -1 max) in your dungeon and add a lava_surface_underground object to the map. Then add the lava_effects objects to each tile (elevation 0).

Also, I reduced the number of particles from your definition as it seems to hit performance with a lot of lava tiles. Now does any one know how I could add magma bubbles effects or any other idea to improve this ?
