**Short description of error**
Hello!
Coming from a VFX background working in the industry for 15y.
It seems right now that udim tiles are recognized if the format is filename_1001.exr
Depending on the DCC like Mari, Painter or others, it's common to have a format like filename.1001.exr.
This format is not recognized, so I have to rename my UDIM textures for blender.
Please make **sure** that all UDIM formats are recognized like <UDIM>, .1001, _1001
This description is taken from T72734:
```
0-based (Zbrush) - select this option if your UV co-ordinates start at 0
Some applications, for example, Zbrush, number the UV tiles with the lower left UV co-ordinate. That is, a UV tile [0,0]x(1,1) would use u0_v0 in its file name.
1-based (Mudbox) - select this option if your UV co-ordinates start at 1
Some applications, for example Mudbox, number the UV tiles with the upper right UV co-ordinate. That is, a UV tile [0,0]x(1,1) would use u1_v1 in its file name.
2-UDIM (Mari) - select this option if your UV co-ordinates are represented as a four-digit number using the formula 1000+(u+1+v*10)
3-Explicit Tiles - select this option to load each tile separately and enter the U and V values explicitly. For each tile, enter the values of the lower-left UV co-ordinate that the texture corresponds to.
```
