Struggling to make a texture 128x64 instead of 128x32 (IA 8b)

it cuts the top half of it...

xungun12•122d ago

it even correctly assign 64 of height in the build file...

bates64•122d ago

you probably need to change the geometry also

xungun12•122d ago

huh? Can you tell me what values?

bates64•122d ago

see NoControllerGfx, just below

xungun12•122d ago

yeah!

xungun12•122d ago

huhhhhh

bates64•122d ago

i think you want to change the last two values (dsdx, dsdy)

xungun12•122d ago

0400?

bates64•122d ago

its in S10.5 fixed point format, there may be a macro

xungun12•122d ago

doubled them to 0800 i'm so loooost! XD i think that editing those values just moves the rectangle

xungun12•122d ago

nope...

bates64•122d ago

i can reproduce this playing around

bates64•122d ago

seems to be rendering like 40px of height

xungun12•122d ago

bates64•122d ago

most likely

xungun12•122d ago

there's nothing else to edit about it

xungun12•122d ago

i guess i have to use 4-bit instead?

bates64•122d ago

ah. that makes sense you can change it in splat.yaml and also change G_IM_SIZ_8b to G_IM_SIZ_4b

xungun12•122d ago

nothing changed even if it is 8b

bates64•122d ago

no background, did the rdp crash?

xungun12•122d ago

just the texture broke

xungun12•122d ago

doubled the dtdy

xungun12•122d ago

same thing

bates64•122d ago

great success

xungun12•122d ago

and it breaks the texture in the assets folder

xungun12•122d ago

🙀 what was the issue?

bates64•122d ago

need to use gsDPLoadTextureTile_4b

I figured this out by looking at a different ia4 texture, map_arrows, and looking at its display list PauseGfxArrows

xungun12•122d ago

oh nevermind XD i forgot to delete the stuff before still broken :/

bates64•122d ago

you changed it to ia4 in splat.yaml and reconfigured, right?

xungun12•122d ago

ooooh to ia4

bates64•122d ago

dont remove lines 179-186 sorry quirk of the diff i sent

xungun12•122d ago

works!!! thank you so much @Alex ❤️

bates64•122d ago

awesome

xungun12•122d ago

it breaks transparent pixels unfortunately, but it's not noticeable!

bates64•122d ago

i didnt have that issue

xungun12•122d ago

semi-trasparent pixels, my bad

xungun12•122d ago

bates64•122d ago

you dont need to hardcode the height (64) on the gsDPLoadTextureTile ah i see. yeah thats not really a problem

xungun12•122d ago

bates64•122d ago

oh change the palette maybe

xungun12•122d ago

IA-4 doesn't use palettes

bates64•122d ago

xungun12•122d ago

that doesn't cause issues tho

bates64•122d ago

correct, its equivalent better practice to not hardcode it though

xungun12•122d ago

it breaks the vanilla texture dump tho that's why i did that .

bates64•122d ago

I see, imo that's a non-issue but perhaps we can find a way around that in future (provide a different splat.yaml for build and split @ethteck)

xungun12•122d ago

👍 also i believe the semi-transparent pixel break is an IA-4 limitation

bates64•122d ago

yeah its an alpha mask mode

xungun12•122d ago

IA8
This format is similar to IA16, but only 4bits each are allocated for intensity and alpha value information. Each texel can be expressed with 1byte, so you decrease the data size.

IA4
This texture format has 3bits of intensity and 1bit of alpha value information.

bates64•122d ago

you should see a warning alpha mask mode but translucent pixels used when it builds?

xungun12•122d ago

nope

xungun12•122d ago

just these

bates64•122d ago

oh, that's because we don't use the python img/build.py anymore and instead use pigment. @ethteck should we add checks like this to pigment?

bates64•122d ago

e.g. for ia4

Ethan•122d ago

howdy folks yeah that seems probably good it might want to be opt-in to get the warnings but idk
