System Information
Operating system: Windows 10 Home Edition
Graphics card: Nvidia GeFroce RTX 2070 with Max-Q Design

Blender Version
Broken: 2.93.1
Worked: (newest version of Blender that worked as expected)

Short description of error
Working from a google drive location (all files set to be available offline)
UDIM texture set generated in Substance Painter
Image Texture containing the the UDIM texture set is connected to the Principle Shader assigned to asset
UDIM tile textures can be previewed in Eevee, Viewport Materials display and in the UV Editor. But when Cycles render is turned on, only the first UDIM tile (1001) display with the rest appearing offline.

Exact steps for others to reproduce the error

Textures and Blender File running off a Google Drive Location
Assign Principle Shader to the model in the scene
Connect Image Texture to Base Color of Principle Shader
Connect first UDIM tile Texture (1001) / Relative Path / Detect UDIM turned on
Setup Mapping and Texture Coordinate nodes via Node Wrangler on the Image Texture node
Verify UDIM maps in the UV editor
Setup Test Area light in scene
Viewport / Material Preview (All UDIM tiles displayed)
Viewport / Eevee Preview (All UDIM tiles displayed)
Change render engine to Cycles (CPU/ then GPU Computer) / Only UDIM TIle 1001 is displaced with 1002 and 1003 appearing offline.

Thanks everyone - hoping I'm doing something wrong and this isn't a bug. Blend file and textures included in a zip.UDIM_cycles_issue.zip

I can say that the UDIMs appear in Cycles when the files are all my local hard drive.

Same here.

@feedreelcinema : Is this only an issue when the files are in the cloud? (does it work for you from your provided zip?)
Also not sure if having Auto Tile Size Addon enabled has an effect here? Does it work for you if it is disabled?

Thanks for the help.
Just quantified auto Tile Size doesn't have an effect whether its on or off (apologies if the mention was out of context).
Unpacking the ZIP file on my desktop and running the scene shows that Cycles does display the UDIM's as it should.
However unzipping the file in a google drive location and the UDIMS appear offline. Just tested this in dropbox and the tiles also show up fine in the render.

So it appears Cycles has a sort of conflict reading UDIM textures from a Google Drive location.

From the Google Drive Extracted Zip, I've unlinked the materials and purged them from the blend file, then tried re-linking using an absolute path (by dissabling Relative Path during import) and it still displays 1002 and 1003 as offline even though they are visible in the UV editor and in Eevee.

Normally I wouldn't say this is a Blender issue but Houdini (relative and absolute path mapping) from Google Drive locations has provided consistent UDIM based renders.

I'll investigate some more on my end to see if there are any Google Drive settings which are causing the conflicts. But let me know if this problem occurs for anyone else trying to run these files from a Google Drive location.

Thanks!

I have Google Driver here, but I can't replicate the problem.
Is the problem replicated with GPU rendering only, or CPU as well?

Thanks Germano,

I just tried again with the file this morning on Google Drive (Blender 3.0.1 default) and the problem doesn't appear to be occuring anymore and all UDIM tiles appear correctly. Tested it with a UDIM set generated in Blender as well as a UDIM set generated in Houdini and imported into Blender via alembic. Everything is working as it should.

To answer your question, when the issue was occurring, it was visible on both GPU and CPU rendering.

Thanks for all the help - I think we can call this ticket resolved. I will reference it if I come across this issue again but I believe we should be good.
