- In this video we look at how to assign images in a folder to random instances of an object for a lot of texturing flexibility!

Thank you Johnny. Very useful. Finally I got to understand UDIMs. This is amazing because the texture changes for every instanced object that is distributed on the faces.
Very well done explanation video! Well done :)
Tip : Use a program like Flash File Renamer to efficiently batch rename files.
Tip : Use CTRL-SHIFT-T with a texture node selected to quickly add the mapping nodes
Reminder: For Ctrl+Shift+T shortcut you need to have node wrangler enabled as addon, it comes with Blender you just gotta activate it.
Love it, thanks for showing us this UDIM trick. I can envisage using this in other scenarios.
Really well explained...thank you...look forward to watching more of your stuff...UDIMS are really powerful...how cool
Thanks!
awesome! Subscribed!
Brilliant. I'm using 26 (not letters but images) with a bunch of compare and mix nodes to get the job done. Messy af.
This should really simplify things, I just have to rename the lookup files and a very simple material node tree.
Awesome, I hope it makes your life easier!
@@JohnnyMatthews Although my original version use two images per surface rather than one which means I have to refine it a bit still, I went from 122 nodes for image selection down to 15 (different random and also a seed control). Only thing I noticed which was kinda bad is that UDIM gets erased during a purge operation, even if it's not listed as a purgeable item. Probably a bug right now, although the file wasn't saved at the time.
Quite handy 😀
I hope so
Thank you, amazing work.
Thanks fits the kind words!
Omg thanks so much for this idea! This is so valuable in a lot of cases for motion graphics. In Cinema4D you have a multi texture shader for exactly this use case. I once proposed this idea to Omar because I wanted to create a procedural book generator back then with Animation Nodes that loads the pages dynamically depending on the needed page count. He developed a small addon that was quite working but for some reasons you had a limit of 48 textures or so that could be loaded in when rendering with Cycles and with Eevee even less I think. Did you test this approach with more than hundred images already? And I guess if you need the images in a correct order like with pages for example you just need to come up with some other math based on the object index, right? Thanks a lot!
I’ll be doing some bigger tests. 26 was the most I tried so far.
Amazing work man!
Thanks!
Sublime! Thanx! :)
Your welcome!
excellent work :)
Thanks!
Your paper stack spread solution from an earlier video would be better to avoid overlap
Hi Johnny, thanks for sharing. Do UDIMs also work with video files? I have to make a multi-monitor background and this method could be very useful.
Thanks again anyway!
Hmm, no idea. I’d have to try.
1st of all - THANKS! 2nd - it brings me to idea how NFT like Peable can be easeally made with this method! One quation comes on top - how can I rename 10K images with UDIM concept? is there software to make it with 1-3 cklicks?
I would guess there are ways to do it in the command line or there are some file renaming app out there. I’ll have to do some googling
Thank you. But I have a question. What exactly does the "Translate Instances" node do? We can do the same with the "Set Position" node.
If you use set position, it works on the points domain, so every instances points will be moved the same way. Translate instances will let you move each instance separately!
@@JohnnyMatthews I understand now. Thank you.
any chance of one texture image but select different region or offset?
Hi! Great useful tip! I tried exactly as your demo. Works 100% ....until switching to Cycles render. Then it seem neglect the UDIM and revert to single (first) image on all only "cards". Tried a lot to find out but beats me. (same result on both 3.2.0 and 3.2.2 on Mac). Any idea? I really need use Cycles 😞
That’s really odd, I went back to my project file and it works in cycles. I’ll post a link to it later today.
@@JohnnyMatthews Great! This might reveal if it works or if a bug in the mac release(s)
I cannot get it to pick up my image texture. I had it for a while, now it is just not working, no matter how carefully I try to follow your step. Can you share this blend file on your gumRoad please?
