Yeah, just add the file extension for pretty much any file in the appropriate place and it should work. m2t, eh? wow.

That happens sometimes with png/webp-s processing. You could try either with lossless settings (as parallaxes), or with adjusted alpha transparency level, and see if that helps with those troublesome images of yours.

Can you upload some sample picture? I'm very curious this issue.
=================================================
I research this issue
"Added code to properly encode parallaxes in RPGM games (must use lossless or it breaks movement)"
Can anyone tell me which game have this issue?
I create a parallaxes test project, have parallaxes movement
but still can't reproduce this issue
maybe i make a mistake on this issue...
this test project have 5 folder
Project1-jpg-lossy
Project1-png
Project1-webp-lossless
Project1-webp-lossy-q100
Project1-webp-near_lossless
libwebp 1.0.3, RPGM 1.61

My (very limited) understanding of RPGM parallaxes is that they're the background images for maps that the player can walk about on. This works like an image map. If the color of a given pixel is changed, it breaks the image map so players can walk where they shouldn't, and cannot walk where the should be able to. Lossless doesn't change the colors, lossy does.
As for the issue that 0011 was having; cruncher works by re-encoding files to more efficient formats but leaving the filename and (just as importantly) file extensions the same. I.e., it will take a 5MB image.png, re-encode it to a lossy webp image that's maybe 200KB, but the filename/extension is still image.png. This allows you to compress assets of a game without changing any of the script/code. When an image is loaded by the game, it looks at the header of the file to decode & display, not the file extension.
cwebp breaks image transparency when re-encoding webp files. I've added nconvert to the latest couple versions of cruncher as it preserves transparency. However, it's much slower than cwebp so I only set it run on files with a webp file extension. 0011 ran cruncher on a game that had already been crunched by the author, so cwebp was run on files with png extension that were actually encoded as webp already.
Hope this helps clarify?
Hello bas ,Thanks for your reply
my english is not good, sorry
1.RPGM parallaxes lossy issue
I understand what you mean.
I compress a lot of rpg maker vx ace and woldrpg game, some game parallaxes folder use jpg and png
and i use some png lossy tool to compress that parallaxes folder...
until see this bug issue, i know rpg maker mv is difference vx ace and wolfrpg *1,
but i very worry, maybe lossy parallaxes will break some game,
so i try to reproduce this issue, know how to trigger this issue in rpg maker mv
but my test project can't reproduce this.
I create a movement route in my test parallaxes picture
and change lossy picture try to trigger this issue,
but still fail, maybe i lost something in important setting.
2. webp breaks image transparency issue
this bug can reproduce,
cwebp resample will break alpha channel.
=======================================================
*1 RPG Maker MV editor only support .png, but nw.js core is support .webp
=======================================================
update 20200316
I think conversion to lossless webp will change png structure.

Nope, Im not using 10-bit encoding/"enable-vp9-highbitdepth" unless it is a hidden default setting in libvpx-vp9...
Yet, I guess Bas is the far more competent person to ask that question here.
And yes, the mentioned game has trouble playing on some older (read "mine") win-systems, and it has nothing to do with compressed/normal versions there.

The color space I use in cruncher is yuv420p, which is 8 bit.
Hello, I just used it and find out that it's not compressing audio (.mp3) files. Did compress (.wav)
Edit: Just tried a game having webp images - Turns out it does not compress webp images also.

Moved this to the thread for the tool I made/use for compressing. Take a look at the OP of this thread and ask any questions you have here.
If you put a lower number the images will be compressed with very reduced quality (More Blur), and if you put higher number images will be compressed with better/good quality.

That's the lossy quality. 100 is the highest, anything below 70 and you'll start to notice on all images, and below like 40 is like minecraft.
