Hello,
I have 3D model in zbrush it has UDIM texture tiles.
Do you know any good tutorial that explains how to load textures in Houdini (UDIM textures).
This is the model i have created.
https://tanel.artstation.com/projects/LwA0v [tanel.artstation.com]
And you can see also textures sample.
(Textured in Mari).
I now need to bring model in to Houdini and load in also textures.
Can you can you recommend some good Houdini 16 Amarok UDIM tutoprials?

Use Texture node, it has UDIM support. Just plug the Texture node to your material's needed parameter. For example, if you use Principles shader, pipe your Texture node's out into its basecolor input.
Also, after loading your first file (yourfile_1001.tiff) into the Texture Map field, put %(UDIM)d. The example is below:
yourfilename_%(UDIM)d.tiff
it will connect all your UDIM sequence.
Hope I could help you).

Thank you.
I will try this evening when i get home from work.
I am not pro in Houdini and trying to understand and learn it.
Have done some small personal projects in past.
And currently trying to learn shaders and how to use my textures with the shader.
Atm i have imported the model (got the geometry node)
I was trying t use principle shader
But im getting confused what node do i create there.
Or should i instead dive inside object level and dive inside geometry node and do it that way?
I am sorry for those questions i know for profecional they may look silly.
I tried yesterday with this method that you see in picture but it for some reason did not work.
I ticked the texture box and i selected my texture path.
But in path i was able to select one file
Should i rename those files as mentioned above and select those both?
or…

No problem, we are all learning in this life. Below I explain in more detail.
In MAT context create:
1. Principled shader and a Texture node
2. Connect Texture node's “clr” out into the Principled shader's “basecolor”
3. Then to use your UDIM, in Texture node load your UDIM's first file then add this to your filename so it recognizes it as UDIM: %(UDIM)d.
For example, if your file is like this:
textures/Shirt.1001.tiff
then do this:
textures/Shirt.$(UDIM)d.tiff
I also attach an image for your convenience.

Thank you so much.
This helps a lot. I am more visual learner. Now i get it.
I also started with this tutorial
https://www.sidefx.com/tutorials/houdini-vops/ [www.sidefx.com]
He spoke there also this text:
When you drag and drop material on to object in render view material will be assignd to object level
As i understand Geometry level is the level where i see all my Object nodes. (Example: start up houdini >> import a obj file. You will get that object node. That same level is Geometry level).
And when i dive inside that node that is then object level
Correct me if im wrong.
Thank you so much for the help you have provided.

You see all your scene objects in Scene level (also called object level). When you create cameras, lights you are in the scene level. When you dive into, you get into Geometry level (also SOP level). However, you can create objects in the Geometry level too by hitting TAB and typing, for example “sphere” or “box”.

Got it working had some issues but found out a fix.
1 issue i had was that i did not know exactly how to load in the textures.
As selecting Principle shader node or textue node.
Also did not know load them in as sequence or single file.
But managed to figure that one out.
Also had to flip UV-s as by default it was not correct.
But managed to fix those.
Now trying to understand how to use use same texture file separate and create displacement or bump based on the textures.
And also how to add glow effect to specific area.
In my model textures there are green parts i want to make those to glow a bit.
Should i export out texture maps that only have those areas painted so i can add glow effect in Houdini separately to those parts whithout affecting other part of textures.
Here is also “short” video where i try to explain as faast as possible in my poor english.
Currently trying to figure out how to use same texture maps and create displcement from textures.
