New issue with MAT COPY Scripts.
Hi there, this is my first post here.
I find myself forced to ask to you guys, hoping in can get a fix to this issue that has been troubling me since yesterday. I recently changed PC so i had to start using DAZ 2025 ALPHA. It worked fine for like a month, then yesterday my MAT COPY scripts stopped working. When i click on it i get "An error occurred while reading the file. See the log for more details". This is what i get i the log.
2025-11-09 18:24:49.326 [WARNING] :: Script Error (E:/Daz 3D/Applications/Data/DAZ 3D/My DAZ 3D Library/People/Genesis 8 Male/Anatomy/Dicktator v3/0_GM 8_1/2_Dicktator_Material Copy v3_GM8_1.dse): Line 304

Soes anyone knows if there's a fix to this, please?
Oh, i want to clarify that this happens with everything having a mat copy script such as breastacular, lickalicious and so on so forth.
Thank you in advance.

I would suspect the actual issue is a step before, that it is failing to obtain the thing it is trying to adjust the label of and so can't find the function on that item. Why it would suddenly start failing I don't know, but please report it (post to the DS Alpha thread and/or open a support ticket). https://www.daz3d.com/forums/discussion/728111/daz-studio-2025-alpha-version-6-25-2025-30407-updated-october-31-2025#latest
In the meantime, you should be able to load the content into DS 4.24.0.3 and get it set up, then save a scene or suitable preset (e.g. a Persona preset) and load that into DS 2025 for rendering.
Yeah that's what i tried and with great disappointment, i can't even load a simple g8/g8.1 m or f for some reason. I can load all my characters and the scripts works fine but then when i load in 2025 ALPHA the graft still looks like it doesn't have MATS copied, so weird it happened all of a sudden. Thank you for the answer though, i'll try to open a ticket
That is very odd, I don't have these products but as far as I know the scripts do their stuff on being run and then just leave regular materials in their wake. Is it possible that this is a content path issue - that DS 4 has access to relevant files thata re not avaialble to DS 2025? Does the DS 2025 log show any errors after loading the character saved from DS 4?
Apparently, those scripts might not be compatible with 2025 ALPHA according to a user that answered me on the other thread. But i managed to fix the g8/8.1 figures to load on old DAZ version so i should be able to fix it with the workaround you suggested
Yes, it depends on what they do and how they do it 9and whether they use any undocumented features) but scripts in general may or may not work. Plug-ins definitely won't work until there is an SDK available and their authors can adjust them as needed and recompile them.
The vendor updated the scripts for DS 2025 three months ago. Check the support thread on Meipe's sub-forum on renderotica.
