Update: I recently had a talk with ChaosGroup on most physically accurate settings for Substance Painter material export. This video is update on the topic:

Update2: As folks at Autodesk pointed out, it is also possible to use OSL Bitmaplookup for this.

Update 3: I forgot to plugin exported IOR maps which are necessary for VRAY. Just plug them using the VrayHDRI node and UDIM tag.

In this tutorial I am taking a look how to create UDIM based texture sets in Substance Painter and how to implement them to 3Ds Max 2020 VRAY render pipeline.

There are several issues I have came across when using MultiTile node in Max slate editor, mostly it not being able to recognize .1001 style naming convention and also not working more than 9 texture tiles.

I show workaround to this which is to name the files -1001 style rather than .1001 and also another workaround which is to use HDRI loader and UDIM tag (in brackets which I am not allowed to type here..).

The latter is in my opion superior and it does not suffer from limitations in the file naming convention and is more robust. Bonus point is that it treats the textures in linear workspace fashion by default.

Here is official Adobe documentation about using UDIMs in Substance Painter

Thank you for watching.
