mysterious [texturesys] errors when using ass

Hello, I still have issues when using ASS in my files. I get [texturesys] error about textures, used in ASS, not existing although they definitely exist and are properly linked.

for example:
[c4dtoa] 00:01:46 21550MB ERROR | [texturesys] /Smooth_Metal_3|oaktramonto597267-edit: Invalid image file "Metal_009_COL_6K.tx": Could not open file: Metal_009_COL_6K.tx: No such file or directory

The last time I reported this it was not resolved. I am not going to investigate further due to the complexity of the scene. It would be helpful if Arnold reported not only texture but also affected ASS so this could be solved.

Perhaps you can look into it if it pops out with someone else.

I remember the issue and could not reproduce it properly. It happened randomly right, with different textures? Is it the same this time, or is it always the same texture which fails?

Does setting Max open files under Textures in the Render Settings help?

Are your textures/procedurals stored on a network drive?

It is weird because if you paste ass into a new blank file and set the same search paths it works without an error message, everything is on built-in drive. Could this be MAC issue?

I cranked up Max open files to 5000, did nothing.

It seems like the problem is not related to the file itself, but exists only in a procedural/texture heavy scene. I'll take another look at your old scene on my Mac.

It is very probably not related to texture files or ASS assets as both render fine in the smaller scene. I hope this information helps.

I wonder if you could build in an option for Arnold to ignore this error and render it through anyway, I have seen an option in an ASS text file to ignore missing texture.

The image shader has the Ignore Missing Textures parameter. There's no global flag specific to this error, if I recall correctly. But you can disable the Abort On Error checkbox in Render Settings / Dignostics. This will render regardless of any error in the scene.

One Ass file rendered fine in a new blank file with identical search paths that were copied from the scene where it caused render error, very mind-boggling. I am positive paths are set correct

You can grep or findstr the ass files to find the reference.
You do have the name of the material.
On Windows, you can run Process Monitor to see where Arnold is looking for that texture.

The fact that it's just the file name, with no path, suggests a problem with the texture search path.
