Reduce texture sizes easily with this script.
It's been noted that Iray is getting more memory hungry in the latest beta. That, coupled with the tendency of PAs to include 4K maps (a good thing normally), even minor scene elements can consume significant texture memory. With this script, each texture of the selected scene element is reduced by half in each dimension (one-fourth resolution). The new textures are saved into the Studio temporary directory by default, so they'll disappear when the application exits. That means you should save your scene before running the script, not after. If, however, you press CONTROL (COMMAND on OS X) while running the script, the newly scaled images will be saved along side the original textures with the resolution appended to the basename (i.e. xxxx_2048x2048.jpg). Just place the script in one of your content folders. Enjoy.
Edit: added icon
Edit: added Connect compatibility
Edit: Fixed for props / primitives

... Wow, very nice, thanks!
I often run into this problem with Skydome stuff, where I want to make sure the skydome is at max resolution but other figures and stuff don't need to be.
You're quite welcome.
Works like a charm -thanks!
@Esemwy You beat me to the punch. But using the Qt Image class to do the resizing was brilliant.....I missed that somehow. Would you mind if I put out my scripts using that technique? Most of my slowdown was getting all the install instructions made up since it used an external program to do the resizing?
Have at it. I discovered the technique a while back when I needed to build icons from textures.
It hadn't occured to me to look into the Qt Image class. Though I do have a question....why are you using scale instead of smoothscale? Just for speed? The bilinear filtering does take a little longer, but normally does help.....though, since we're doing powers of 2 reductions (1/2 and 1/4th) I suppose it won't help much.....
Exactly so. In scaling by one-half, I felt smooth-scaling was unnecessary.
Do you know if this will work on Content installed with Daz Connect? I'm concerned about the ability to save the scaled textures in the folder with original textures. Daz Studio does not allow adding files to the Daz Connect folders usually.
Hmmm... Good point. I don't use Connect. I'll see what I can do about that.
It should. It simply pulls the list of images from the list of selected skeletons in the scene. Those images have their own paths, and it saves (depending on if CTRL is pressed or not) to the Temp directory, or the directory they came from....regardless of if it was downloaded via connect or via DIM or even browsed to. Mine does that too, though a little differently. End result is that the images are loaded/saved based on where they were originally loaded from.
And I thought DAZ Connect directories weren't locked. But that is a possible concern if you tried to save to a Connect directory and Qt couldn't save to it. Saving to the Temp directory should still work.
(I don't use Connect either....so haven't tested this.)
Well, I have 95% of my content installed with Connect. I'll try it and report back with what happens.
Does connect put textures in 'My Daz Connect Library' or in one of your other content libraries? I'm working on a solution now that should redirect connect paths to the regular content folder.
Everything installed by Daz Connect goes into the "My Daz Connect Library" (I actually named mine Daz Connect Data and put it on drive D.) An example file structure for me is D:\DAZ 3D\Studio\Daz Connect Data\data\cloud\1_23585\runtime\textures\sarsa\peasantmale.
I haven't tried saving (I also use Daz connect) but I will say - Thank you!!! you are a gentleperson and a scholar!
Just tested it on a scene that more or less froze my system when I tried to render it in Iray originally. Now, no problem at all.
I may actually go back to playing with Iray now. :)
Glad to hear it!
Well, I tried it (CTRL click on script) with items installed with Daz Connect. I seemed to work with no error messages. Then I saved the scene with a new name, closed Daz Studio 4.9.3.166 and reopened it. When I loaded the saved scene, it couldn't find any of the texture files that the script had created. I will investigate further...
When I go back and look in the Daz Connect folder where those reduced fies were created, they are still there. I will need to open a scene file and see if I can figure out why the saved scene file doesn't find them.
@barbult (or anybody else using Connect) try this version. If it works, I'll replace it in the main post.
Edit: I see nothing wrong in the Scene file. But, if I open the original scene and try to substitute one of the save reduced files for the original file by browsing in the Surfaces pane, I get an error pop up. Daz Studio/Daz Connect will not allow me to retrieve the reduce file that way.
Good to know. The above version will use your 2nd (contolled by the constant at the top of the script) Content directory if it detects that the texture is in the Connect directory.
This is the same huge issue I have with saving any material preset or morph I make for any Daz Connect installed items. I cannot save it with the original files in the Daz Connect folder. I have to create (manually) a parallel folder in another content library and save it there.
Oops just saw your new version. The comments above refer to my attempts with the original version.
I tried the new script. When I hold CTRL and double click the script, an error pops up telling me to look in the log. This is what I see:

Awesome! You're welcome!
I note it works for you now, but to address your original issue about not finding the textures - using Ctrl made the script save the resized texttures in the DAZ temp diretcory which, when you shut DS down, is cleared out. So, naturally, when you restart DS they are, indeed, gone!
No, you misunderstood. CTRL stores the images with the originals. When they are stored in Daz Connect directories, DS refuses to reload them. They were not deleted,. They were not in the temp directory.
I'm getting a bunch of warnings in the log file, even when the script seems to be working. Do I need to be concerned about them?
