Sorry you had problems with this. I just rechecked the format - and it looks like it would need to be "normal.1001.png" (sorry for the incorrect information above). I haven't been able to find a definitive definition of the filename format anywhere, so I am just working on the information from https://help.thefoundry.co.uk/modo/902/ ... kflow.html.I had change my file names various styles. like "normal_1001", "egg_normal_1001", "eggnormal1001".....all efforts are failed.
I don't know why can't apply it..and modo octane render always texts same message...
I solved this problem manually.
i use 'image still->uv->udim' option.
handling manually udim U and V coordinate and uv textures.
but still want to handle auto ways like your tutorial..
