UDIM workflow Tweet

[dotcom]

Hello,

There it is for Redshift, nice and clean : https://youtu.be/X9nhwaQUjyM
with this <UDIM> thing you just add in the filename link and voilà !

So i was wondering, what's the workflow for Octane ?
The v4 added features is talking about udim tiling node, do you know if there's a tutorial about that somewhere ?
haven't found one, i'm sorry.

I'm also interested in a tutorial showing how to place udims in uv from within Houdini.

I thank you very much,
cheers,

[Edit] found this about tiling process in 3DSMax : viewtopic.php?f=27&t=68575
gonna give it a try ... ++

The workflow in Octane is the same. In the Texture Image UDIM node, the tiled filename is configured adding the <udim> or <uvtile> tags, for example "myTexture_<udim>.jpg"

Hello,

For some reason i cannot make it to work. i'm in need for more help.

Naming is good i guess : project-name_version_<udim>_(color, rough, bump etc).png

In the obj / shopnet i created a new Octane network / dove inside and / connected a texture image Udim node to the / material universal / (connected to the octane out node)
( I thought Octane was according less memory usage to texture image greyscale than texture image rgb but the udim node seems rgb based,
would it affect memory usage if we had a new octane node called greyscale udim node ?)

If concerned maps are greyscale, do i have to divide the vector to float for it to work ?

Does it work if the maps are not of the same pixel dimensions in the same link (2k, 4k and 8k maps) ?

Empty tile color set to 0 0 0

grid size set to 1 1 (tested also 0 to 1 and 1 to 6)
Does the grid size concerns the actual udim : from 0 to 1 space uv in a 0 to 1 grid ?
Does the grid size means the actual uv dimesion : from 0 to 1 in a 0 to 1 grid size ?
Does the grid size concerns the actual udim tiles : from 1 to xnumber of tiles size ?

image chosen layer name : empty
concerns exr layers, right ?

Do we have to connect nodes to the transform and projection in the ins of the texture udim node ?


Thank you,
