Issues with automatic UDIM location (2025-11-27 06:18Z)

User (2025-11-27 01:52Z)

why can't I automatically locate those UDIMs?

Preparing explanation on UDIM naming and search path

---

Blender only auto-resolves UDIM tiles when it sees the exact naming pattern it expects and when the search path contains those files.

• Texture nodes look for <Basename>.<UDIM>.<ext> or <Basename>_<UDIM>.<ext> where <UDIM> is a four-digit tile ID (1001, 1002, …). Your files are named Squirrel_Fucker_Low_Body_NREW_BaseColor_sRGB.1001.png etc., which matches the pattern, but Blender still says “bad textures” because the path it stored points somewhere else (//textures\...). The “Find Missing Textures” dialog only searches relative to that stored path unless you add the correct directory.
• If the original file was packaged with a different relative path (e.g., //textures/SquirrelFucker/Body_NREW/...), Blender won’t automatically switch to D:\NSFWAssets\char\... unless that specific folder is added and “Find textures in this folder” is run. Make sure the Search path points to the directory that actually contains the UDIM files (D:\BlenderAssets\textures\SquirrelFucker\Body_NREW) and press “Find textures in this folder” after selecting the broken images.

In short: the naming is UDIM-compliant, but Blender’s stored path still references another folder. Add the actual texture directory in the search list and run the finder—then the UDIM tiles should resolve automatically.

Could not find 'Squirrel_Fucker_Low_Body_NREW_BaseColor_sRGB.png' in 'D:\NSFWAssets\char\Scrag_Boy\SquirrelGirl\textures' Could not find 'Squirrel_Fucker_Low_Body_NREW_Emissive_sRGB.png' in 'D:\NSFWAssets\char\Scrag_Boy\SquirrelGirl\textures' Could not find 'Squirrel_Fucker_Low_Body_NREW_Normal_Raw.png' in 'D:\NSFWAssets\char\Scrag_Boy\SquirrelGirl\textures'

Explaining UDIM filename issue

---

Blender is looking for single-texture files (…BaseColor_sRGB.png, …Emissive_sRGB.png, …Normal_Raw.png) inside D:\NSFWAssets\char\Scrag_Boy\SquirrelGirl\textures\. The files you actually have are UDIM tiles named …BaseColor_sRGB.1001.png, …1002.png, etc., but they live in D:\BlenderAssets\textures\SquirrelFucker\Body_NREW\. Since the stored path and filename don’t match, Blender can’t auto-resolve them and prints those errors.

Fix options:

• Point Blender at the folder that truly contains the UDIM set (Body_NREW) and run “Find textures in this folder.” Blender will then discover the .<UDIM> variants.
• Or move/copy the UDIM files into the path Blender expects, keeping the .<UDIM>.png suffix.

Once the folder and pattern match what the material node references, the UDIM images will reconnect automatically.

I made texture soup straight from the original file (write local) why can't it find those 3 files?

D:\NSFWAssets\char\Scrag_Boy\SquirrelGirl\textures

Analyzing Blender UDIM and file naming issues

---

“Write Local” only copies whatever files the MaterialX/FBX points to—it doesn’t rewrite Blender’s image node settings. The nodes in that SquirrelGirl rig still reference three single filenames (Squirrel_Fucker_Low_Body_NREW_BaseColor_sRGB.png, etc.) in D:\NSFWAssets\char\Scrag_Boy\SquirrelGirl\textures. When you baked/exported “texture soup,” you produced UDIM slices named …BaseColor_sRGB.1001.png, …1002.png, etc. Blender now has two mismatches:

• Path mismatch: the node still expects the original folder (SquirrelGirl\textures) even though the files you care about live
