This section specifically means portraits in portraits.2da that are not tied to a particular creature appearance. Those are usually found with the creature themselves.
The base game ones will get a 4x upscale (or reuse the _H one as a lower sized one) and any new ones will be listed here.
portraits.txi
This file must be included and be blanked so that the mipmaps of DDS files on portraits doesn't ruin the quality at high resolutions and high scaling values (eg; x3 or x4). It otherwise takes some weird cross section of the file when resizing it or viewing them at distance.
Methodology
This is from the 4x project.
Crunch Options
All portraits won't have alpha so forcing -DTX1 on nwn_crunch is the key to lower file sizes.
New Approach
After some testing of the below (renaming some files, copying others) it is actually beneficial instead to use the mipmaps of the 4x option.
This will need likely some GIMP scripting but could be much simpler as well - you end up with a source _H PNG, then you generate the DDS of it, and from that DDS generate the 4 other files.
Gives each portrait a relatively optimal "size" but retains all the upscaling details that bring back quality.
Same can be done for the placeables just using the M instead of H.
Alternatively: Just use crunch rescale; see how that does - remember DXT1!
nwn_crunch.exe -file -i "..\sources\*h.png" -outdir "..\out" -fileformat dds -DXT1 -yflip -quiet
Creatures
We want to upscale the Huge portrait which is highest quality option available to be the new Huge. Then we cut this one in half for the Large.
Then we reuse H, L and M for M, S, T.
| Portrait Size | Use | Original Size | TGA Size | 4x Size | File Used | DDS Size | Notes |
|---|---|---|---|---|---|---|---|
| Huge (h) | Chargen only really | 256x512 | 385KB | 1024x2048 | H upscaled | 1.33MB | |
| Large (l) | Character sheet | 128x256 | 97KB | 512x1024 | H upscaled, and halved | Sizeable increase in quality | |
| Medium (m) | Top left portrait | 64x128 | 25KB | 256x512 | Rename original h file | 4x the original size so should be good (and not too large) | |
| Small (s) | Sidebar portrait, conversations | 32x64 | 7KB | 128x256 | Rename original l file | 4x the original size so should be good (and not too large) | |
| Tiny (t) | Tab "see names" portrait | 16x32 | 2KB | 64x128 | Rename original m file | 4x the original size so should be good (and not too large) |
For placeables since they lack H and L (mostly! there are 1 or 2 that have them, perhaps since the portraits are reused on creatures for some reason).
| Portrait Size | Original Size | 4x Size | Option to do |
|---|---|---|---|
| Medium (m) | 64x128 canvas; upper 64x100 used | 256x512 | Keep since highest quality upscaled version |
| Small (s) | 32x64 canvas; upper 32x50 used | 128x256 | Resize M version by / 2 each dimension, to be new s (or we do the s file) |
| Tiny (t) | 16x32 canvas, upper 16x25 used | 64x128 | Reuse original m file |
Oddities for the different options below:
- po_plc_rainbw_h - Placeable but has h and l versions
- po_plc_bbl_sm_m - This one has ONLY the medium one for some reason
- po_msc_ - several placeable ones not marked "po_plc_" for some reason
- po_levelup - only file, used in the top right for levelup (Equivalent I think to "m")
- po_gi_x0horse_m - I think a placeable one, has only m/s/t
- po_door01_m - placeable or door but not named po_plc_ so has only m/s/t
- po_pause - solo file like levelup that has just the "m" sized variant
- po_timestop - solo file like levelup that just has the "m" sized variant
- po_unknownpc - Special solo file
- There's also a few default portrait files not prefixed po_ likely used in some cases
Can remove:
- po_plc_x0_syt_s and po_plc_x0_tyt_t are the same item, no "m" version, and thus misnamed or the only ones. Neither appear in portraits.2da (syt/tyt). Looks to be a destroyed version of po_plc_x0_myt_m.
- Unused due to odd names not sure why they're even there:
- po_pwc_mage_001_
- po_pwc_post_001_
- po_pwc_rubl_001_
- po_pwc_rubl_002_
- po_pwc_rubl_003_
- po_pwc_sand_001_, po_pwc_sand_002_, po_pwc_sand_003_ and po_pwc_sand_004_
- po_pwc_sieg_001_, po_pwc_sieg_002_, po_pwc_sieg_003
- po_pwc_skull_01__
- po_pwc_tabl_001_, po_pwc_tabl_002_
- po_pwc_torc_001_
Original Portraits Upscaled
To follow. Need to pick out which ones are appearance.2da related.
New Portraits
To follow.
Naming convention would be: po_op_XXX_t.dds (where T would be the appropriate size ID). XXX can be 9 characters long. This is because of portraits.2da limitations (you are forced to use po_ as a prefix!)
