"so i've concluded this tread (as far as i'm concerned). thanks for all the help riccardo and Helvetosaur :) i've managed to move on in my project from this phase of exporting the textures. couldn't have done it without your…"

""cool story bro!" XD glad to hear it..."

"hey riccardo  just wanted to keep you posted that i'm making progress with your scripts, for some reason not all the textures are being replaced, perhaps issues of groups, joint meshes etc.. i'll keep you posted soon  thanks :)"

"sure, instead using rhino.messagebox , add a text element with a different 3dpoint origin for each for/next cycle increase the value 100 if you still dont find something.... -runscript (sub listmaterials for i=0 to 100 Dim material_texture :…"

"hey :) some good news, now it seems like it might be working, after i copied just 1 of the geometries out of the big rhino file and into a new one. still something weird that only 1 of 34 textures doesn't want to get chagned :) do you have by…"

"1. good to know 2. the script CAN change the material path/name to something that dont even exists in your computer, it works blindly!... but after, rhino would give you an error for missing texture... post the file :)"

"Great tool, by the way- if you're a newbie- good on ya !!  so i guess i'm a newbier newbie. :)  so the tool works and i think it helped me understand something. 1. i've been going into the materialeditor to see how many…"

"if the script stops at the stard and nothing changes, it means that it stops at i=0 ... i think meaning the first slot of the material list is not a material with texture or simply the material does not exist.... (again i dont know how indexing…"

"hey :) so first of all i've deleted all the "basic materials" without textures , just thinking that maybe those ones actually don't have paths for their textures (just colored materials etc..) so i was left with 4 materials with…"

"i've look better your screenshots... it say "string required" the function Rhino.MaterialTexture should always return a string as output, IF the material of that for/next cycle index EXIST... maybe some maretial in the index are…"

"thanks riccardo,  the whole loop and index thing i understand actually that was not a problem.  but have you had a look at the error that was generated?  i have no idea what it could be. because it worked on my test rhino file with 2…"

"sry i'm not excelent in english .. XD are you saying that the script interrupt before finish it job? or just showing the error but everything is fine? the for/next cycle i used ... started from "i=0"... meaning it is already the…"

"hey there guys ! so i've tested the script and it works on my test file :) many thanks and kudos! but.... on my actual file- error appears. i'm attaching 2 pics here- one to show the whole path of the png texture trying to replace, (no…"

"P.S. do a backup or similar before start the script.... just in case and after the script done his job... check the best you can, because the script, in fact, EDIT your rhino file.... so do all your precautions... please"

"Unfortunately, I tried something similar, but it didn't work here...  Still trying to figure out why. --H"

"wow thanks so much  Riccardo Majewski :) i'll try this as soon as i get back home in a few hours  and i'll let you guys know asap thanks a million :)"
