EPF/PAL Animations about tkviewer HOT 6 CLOSED

Created a topic on ResHax.com to get some hopefully get some collaboration going :)

I need to breakout the file formats and EPFViewer into its own project, but I do intend on open sourcing the tools 😁

I think the "missing colors" might just be color offsets - on top of cycling the palettes. I still haven't found the perfect "Merchant armor" color.

I'm going to try to do this sometime this week, work got busy - stay tuned!

Using the Masters ward as reference:

EPF: shield0.dat:Shield0.epf
PAL: char.dat:Shield.pal

After dumping all the EPF frames, I see 20 frames (using Palette[0]):

Focusing on Frame 129 (Front-face of the shield):

Shield.pal has 22 palettes, so if I scrub the palette from 0-21 for Frame 129, I get:

I don't think that simply changing the palette index will achieve the color animation of NTK/Baram.

Maybe the palette index itself doesn't change, but the color within the palette changes - not sure.

EPF/PAL TL;DR:
A palette is an array of 256 colors.. EPFs - for every pixel - point to a particular color within a palette. So each "pixel" in an EPF is 1 byte (0-0xFF -- opposed to 4-bytes rr/gg/bb/aa) pointing to a color within the 256-color palette.. I've never nailed down the correct industry term for this graphics format, maybe Indexed Color Palette?

Anyways, just some notes..

I tried to shift through all the colors of the first palette and wound up with these 256 frames:

If there's 8 frames in the animation, I'd think 256 colors / 8 frames = 32 color offset, but if I do that it doesn't seem to work:

I think I'm getting close..

Looks like you solved this. Perhaps those findings has implications for #27 as well. I took a look at it for a bit but this was my first time really delving deep into these file formats so I didn't get too far. Maybe I could borrow those fancy tools you have? 🙂

What I wanted to know animation loops was figured out and implemented in this Godot 4.x project:
