Night of 100 Frights HD texture pack: alpha audit

A check of every texture in the HD texture pack by dogerki (upscaled with Topaz Gigapixel AI) against the game's original textures, looking for transparency the upscale got wrong. It started with issue #16 in Scooby-Doo: Refrightened: the broken greenhouse glass hid the plant behind it. Dolphin with the same pack shows the same problems, so they're in the pack's PNG files, not in the port.

Fixed PNGs: download the zip from issue #16 and copy the files over the ones in texture_pack/ScoobyHD.

What goes wrong

Where the original texture is fully clear (alpha 0), many HD files have alpha 1-15 instead: invisible in an image viewer, but the game seems to draw anything above 0 for cut-out textures (glass, leaves, grass, webs) and hide what's behind it, so those areas show up as dark shapes. Glows and smoke are blended, so faint alpha there is harmless; that's why a suspect is only fixed after someone has looked at it in game.

The audit matched 1588 pack textures to the disc (66 pack files are textures the game builds at runtime and aren't covered). A texture is a suspect when the numbers say so; severity is only a guess from the numbers.

Fixed so far

Porch webs (T005)

Smuggler's Cove sign (T001)

Leaves (T002)

Grass by the fountain (T003)

Porch web (T006)

Greenhouse glass (T025-T027, issue #16; needs a closer recheck)

The evidence from issue #16: Scooby-Doo: Refrightened (top) and Dolphin with the same pack (bottom), each with the original textures, the HD pack and the fixed PNGs.

Checklist

Ticked = looked at up close in game: fixed, or fine as it is. The issue #16 fixes are in the zip but still need that closer look.

All suspects

Strips: HD texture | alpha differences from the original (red = alpha where the original is clear, boosted x16; blue = see-through where the original is solid). Fixed textures get a third panel: the fixed HD file. Grey checks = transparent.

1. The Mystery Machine

T001 high fixed  sign_smugglers.RW3 tex1_128x128_665c7b880e4081e9_5.png
scenes: h001

• HD has no alpha channel
• the original has transparency
• visible alpha (>=32) over 100% of the original's clear area (max 255)
• In game: The HD file has no alpha channel, so boards the original hides behind the sign are drawn.
• Fix: alpha taken from the original texture, scaled up.

T002 medium fixed  g_leaves.RW3 tex1_64x64_171866a6033d2d46_5.png
scenes: h001 h002

• faint alpha (max 15) over 29% of the original's clear area (the #16 pattern)
• 45% of the original's solid area is slightly transparent (alpha < 250)
• In game: Faint alpha (up to 15) where the original is clear: the leaves draw dark shapes round their edges.
• Fix: alpha set to 0 where the original is fully clear (and alpha < 16 to 0 in the one-pixel edge band around it).

T003 medium fixed  ogsh0005.RW3 tex1_64x64_2a616a895033c3c7_5.png
scenes: h001

• faint alpha (max 7) over 31% of the original's clear area (the #16 pattern)
• In game: Faint alpha (up to 7) where the original is clear: dark patches round the grass.
• Fix: alpha set to 0 where the original is fully clear (and alpha < 16 to 0 in the one-pixel edge band around it).

T004 medium not checked  opdo2402.RW3 tex1_64x64_4d41626f2479a886_5.png

T005 medium fixed  owbh0002.RW3 tex1_64x64_543b9902daf3c13c_5.png

• faint alpha (max 2) over 64% of the original's clear area (the #16 pattern)
• In game: Faint alpha where the original is clear, plus a faint skirt round every strand that draws a dark outline over whatever is behind the web.
• Fix: alpha set to 0 where the original is fully clear (and alpha < 16 to 0 in the one-pixel edge band around it); edge pixels take the colour of the nearest strand; alpha ramped so 60 or less is clear and 110 or more is solid (strand width matched to the porch web, T006).
