unit images creation

[hermestrismi]

I need help to create images for my campaign (animations, frames, idle...) for fiery and glacial units (for both parts: shamans, ranged units, tank units, leaders, guardians, ... ).
if it's NOT possible, is there any fractions or campaign that contain such units that I can use freely?

[Shiki]

It is possible, but answering that part anyway

is there any fractions or campaign that contain such units that I can use freely?

Scroll through that list (it's very long though, >2000 units IIRC)
https://units.wesnoth.org/1.14/Ageless_ ... 20Era.html

Some might be:
the "Frozen" faction
the "Elementals" faction
"Summoners" faction has Elementals too
"The Warg" have flame spirits

From an add-on maintainer's perspective, it's best to not copy the WML files from the add-on, but to let this other add-on provide the units. That avoids the long-term issue of keeping the code up to date with Wesnoth's development.

Yep, moved.

If you are willing to pay money than I will make unit art for you, if you want to than I will send you a preveiw free of charge(if you do want a preveiw than I will need a description of the character, the action he/she is doing and the frame count you want.)

It's certainly possible to create artwork for units, but it's a lot of work and I'm no artist so can't advise.
Your second question is option I'd explore first.

Assuming you are creating content for wesnoth version 1.18, then mainline has 2 fire units; guardian and it's advancement, fire wraith.

There are many custom UMC units and amongst them are probably ones that will serve your purpose or can be adapted to do so by changing their properties via WML and maybe tweaking their artwork (sprites and/or portrait if they have one).

The wiki provides guidance for new content creators including custom units and artwork.
If you haven't done so already I suggest you have a look through there.

Many custom units are listed on the units page in the eras* link as shown below. *Not updated for a few years.

Hope this helps.

Cheers!

You can have a look at the elementals for example here https://units.wesnoth.org/1.18/War_of_L ... actionless
You can also use my ice trolls if you want https://units.wesnoth.org/1.14/Legends_ ... tml#Trolls
They are currently on 1.16 but I plan to port the campaign to 1.18 before the end of summer. (I do not know why they do not appear in the 1.16 units database)
