It is a mesh, named heromonsterbillboard01.msh and found under xpack/effects/particles/creature

Having looked at Atlantis they did it justice visually wise. Gorgeous scenery assets and probably the most intricate landscapes TQ has ever seen.
And knowing World Editor (yikes) it really does deserve high praise.
Gameplay wise however it felt lacking insight.
Repetitive new player skills, didn't look much into new itemization but from a quick glance there are three bows in a row with the same granted skill which is a fairly odd decision. And who could've thought one day a telkin is gonna be a final boss huh.
Overall I do wish Ragnarok was more something like that.
Yeah on the bright side, there are signs of new easter egg content being in the works that's probably going to be sneaked in a few updates down the road.

Simple in the light options is shadow related, e.g. simple light won't cast shadows.

Motion Orient:

Pretty much what it says, orients texture towards its emitting direction.

Regarding shaders, another commonly used one is ParticleDistort.ssh (as the name suggests used to create distortion effect).
Worth mentioning AE PS Editor saves to & loads from only specific directory, that is ...Working\CustomMaps\Art_TQA2\source. Also add Options tab overview (such as choosing background color/texture, inserting/removing entity).

Alright you piqued my interest. Upload the anm & fx (and related .dbrs) if you like, I'll take a look.

Not much difference from a player's standpoint I guess, other than that Quake actually has its stuff properly fitted and optimized compared to an ARPG mod.
Or if you meant why bother making something like that when there are proper shooters out there, it's rather simple, I just felt like it.

Alright there's been change of plans. Scratch the original idea, it's a pvp map now.
OP updated.
Let me know what you think.

you should put it, it looks fun and adds a litle of warming "boss incoming"

It looks absolutely awesome

Wooot !  keep on your work 

Thanks!

Uploaded following changes:
Added more unused gear, including kite shields, couple of staves, swords & spears. Some common weapons that had different versions looking the same received new looks again
Adjusted bucklers' bitmaps
Normal torches received unused crude look. The vanilla look stays for Epic & Legendary torches that were previously unobtainable
Revamped the sling
Added cyclops quest scene & a special chest
Unused Dream pet Dream Guide utilized as a nightstalker hero's summon

New full list of added unused gear featured below

Now however onto a more technical side of things, the mod's getting bulky so fellow modders feel free to let me know if I should create a separate records folder to contain the mod's stuff when it's feasible, for easier incorporation.
Yeah also I never explicitly mentioned it but do note I expect a credit mention should you make use of this project or some part of it
