Nuke/MARI Bridge: Multi UDIM Gadget

LEVEL: ADVANCED

[dropcap cap="N"]uke does not natively recognise more then one UDIM or in other words, any UV groupings outside of 0 to 1. This is kind of a limitation of the Nuke Mari work flow since MARI’s power comes from using multiple UDIMs. This tool I created enables Nuke to recognise and map an obj with more then one UDIM correctly. I have limited the tool to 10 UDIMs (1-10). Not sure why you would want more then that. You can specify the size of your textures and you can toggle to see all of your textures at once . I would assume that at some point The Foundry will make this work natively without the workaround.[/dropcap]

Nuke/MARI Bridge for Matte Painting Demo

ADVANCED

This demo shows how to integrate what comes out of MARI into your nuke projections. The Nuke/MARI Bridge is still kind of new and I think people are not sure really how to utilize it yet. To my knowledge, there is nothing like this article out there that explains how to integrate MARI into Nuke from a matte painting point of view. All that I have posted here are things that I have explored and developed myself--I think this is cutting edge of matte painting right now.

In the below image, on the left, is a pillar that is comprised of 4 projections setup in Nuke. On the right is the MARI paint (not the best example of what MARI can do--you can take it a lot farther and do a lot trickier stuff but it was fast to do).

Maya Multi UDIM Shader to View MARI Models

LEVEL: ADVANCED

To accompany the Nuke UDIM Gadget is this a Maya shader that will allow you to see all the textures on your multi UDIM geo from MARI. Just read in the images to the corresponding nodes in the hypershade and you are good to go. I have only allowed for 10 UDIMS (that is from 1-10) but you can add more if you dig around the shader to see how it was constructed. I am not giving a lot of explanation about how this shader is put together because I figure you can figure it out if you dig through it.

Getting Multi Patch OBJs Working in Nuke for MARI

I made a post named "Nuke/MARI Bridge Multi Patch Gadget" a while ago. In that post I did not give a real indepth explanation how the multi patches or the gadget works and how to use it. So I wanted to make this follow up post and video more fully cover the subject. I often use multi patch (or UDIMS) in Nuke for Matte Painting. It is also the workflow I use when working with MARI. I believe that the Foundry
