Multy UDIM density/length map Problem

Hello,

 

I have a character with multy UDIM, the scene is in Max 2021 and rendered in Vray next 3.2.

I would like to add a painted map (as density and Length) for building a Beard, the painting goes over 2 UDIM, unfortunatly I'm not able to make 3DSMax read the different Udim (only one was readed.

I tried different solution, Vray multysubtexture, Multy tile and OSL bitmap Lookup, I named the texture with the UDIM suffix (texture name.UDIM NUMBER.format), but seams that not works.

I looked at the tutorial for Maia (https://ephere.com/plugins/autodesk/maya/ornatrix/docs/1/Hair_Texturing.html) but I haven't found something for Max.

Can you help me?

Thanks in advice

Hi,

If I understand correctly, the problem is that 3ds max itself doesn't read the UDIMS? Or is it just Ornatrix? What happens if you use the UDIM maps in a polygon mesh instead of a hair object?

No I have only problem with the OX modificator that not read the Multy UDIM but only the first one, the rest of the scene (material and so on works fine)

I see. Thank you, I will take a look and get back to you asap.

I just tried with a mesh with four UV tiles and a MultiTile node in Max 2019. It seems to be working fine here with Ox modifiers. In this test is connected to Ox Stand length modifier. See image below.

I loaded the maps using these instructions:
