Texture Compression in Daz Studio - what is it and how to avoid it

Today I'll explain the Iray Texture Compression and how to adjust/disable it. It's a feature that's trying to save you some VRAM at the expense of compression artefacts akin to JPEG images. Up until Daz Studio 4.22 those settings could not be saved and would reset after a restart, but in the latest Beta version 4.22.1 (and later releases) these settings are moving to a different location and can be saved as part of your scene or a Render Settings Preset.
Enjoy, experiment and tell other users about this!

I had been banging my head for the past two days trying to figure out why my textures arent feeling detailed enough. Never even knew compression of textures was a thing, thank you for this.

[@BennieWoodell]

Thank you so much! I'm downloading the updated Daz studio versions now to get the settings I want saved instead of having to do it each time.

[@milo13200]

Thank you for that useful tip Jay! Have a great day!

[@obviousalias9506]

Thanks, Jay, this is very timely! I've been having trouble with the shadows in a render, where the light comes in through a window to illuminate a marble floor. The shadows from the window cross-frame, however, look *very* jagged and false, almost like cartoon lightning bolts stretching across the floor. Just today, posters were suggesting that, since everything else in the image seems correct, the Iray compression settings might be the cause. I'll take another look at correcting things, knowing what you've taught me, Thank you!

This was helpful for me.
I like the move they are testing with the beta.
An eventual further improvement from there could be an override setting in the shaders.
I recall a few experiences where the offending texture was just one, and it would be a waste of resources to turn off compression globally.

[@ErikMKeller]

So for the time being, we could use a pre-saved scene with all the settings set to our liking? Like, e.g. Blender 😎
Thanks for letting us know.

[@WPguru]

Sadly no, the beta and the next version of Daz Studio allows that, but not 4.22 or earlier. Those compression settings are not saved with your scene file.

[@ErikMKeller]

@@WPguru Ah, sorry. I thought that a saved scene file will keep these settings.

[@DEVIANT...]

i make it 8k, been using 8k maps but maybe i might make it 16k lol

[@WPguru]

32K for the win 😎

[@DEVIANT...]

@@WPguru haha

Jay, you are the "Neil deGrassial Tyson" of daz studio bro 😂 I love all your videos man, you do a great job breaking all this down. If not for you people would probably have just Abandoned daz all together. Daz studio needs to start paying you. I bought the "compression optimization" from daz store, I'm still running a 3070ti, I probably need to just upgrade to the 4090. What do you think? Is it worth it? Also can you post your computer breakdown on your page so us non computer geniuses know what to buy.

[@WPguru]

Thank you 🤩
If you can hang on until September, NVIDIA are expected to bring out the 50 series cards (or whatever they'll be called). It'll make for new models and also make the 40xx series potentially cheaper. Get something with 16GB of VRAM or higher. For system RAM, I recommend at least 64GB. CPU isn't that important, so no need for the latest i9, but stay away from i3 and Surface/Copilot+ devices.
