"Pixelated" GZDoom Warp Shaders

[DustedPandemonic]

This features 4 of GZDoom's warping/wave shaders, each tweaked to output warping textures that are accurate to the original texture's resolution.

Simply: pixelated shaders that look like software mode! Similar to software mode liquids in games like Quake and Quake 2.

Also featured is the warp2 shader applied on an Evil Eye prop.

Included is a test map showing off each texture shader.

Might be a rather late reply, but I might see some good usage out of this!
One question though: How well does it handle non-power of two textures, and would I be able to override an ANIMDEF lump with said shader?
Askin' as I'm working on a mapset for The Adventures of Square, and I wanna replace the normal liquid/waterfall textures.

Hm, just tested it out and seems like the ANIMDEFS lump takes priority over using shaders like this, so you may have to make a copy of the textures you want to replace.
I tested the same shaders on a blood fall texture (64x128) and even cropped them a bit (61x111 just to test) and they seem to look fine but still a bit different compared to a square flat shown in the test map.

Dang, really? I might have to see about getting that changed over at the UZDoom git repo.
Maybe something like an override definition in the ANIMLUMPS file could work?

Very nice! I was just thinking the other day how no one's made a software-accurate liquid warp shader yet.

What's the usage license for the shaders?

GPL 3, since these are just edited versions of GZ/UZDoom's shaders. I'll update the pk3 to include that real quick!

[Nash]

Wonderful, thanks for the clear licensing update!

Never understood how to use WARP3 and WAVEX.

Now, I wonder if it's possible to recreate Half-Life's software mode water shader.

A fair bit of warning, I suppose, although to be clear, it is not at all DustedPandemonic's fault... but rather, just the nature of how these shaders work:

The shaders won't look good with texture filtering enabled - the visuals simply wouldn't match (the modified warp shaders will still have a blocky look/aesthetic to it, compared to every other smooth-filtered texture around it that does not have any custom shaders).

As I said, not anyone's fault, it's just due to how the shaders work to purposely mimic the blocky look.

These shaders work best when used with no texture filtering all around.
