Randomise textures

CadFather

here's a script i finally found that randomises the position of selected textures - great idea to avoid patterning.

my question is - is there any way to randomise the rotation as well?
this could be useful for textures like soil, vegetation, stone, water etc

i found the script from Didier's depot but i do not the author

EDIT 2: watch out! when the front face has no texture assigned (even if the corresponding back face has one), the script crashes SU(7) - if i paint the front face and run the scripts it works (though the back face gets painted in the process)

Hi CadFather !
It's hard to rotate a texture. Specially those are not parrallel to axes.
I try to make a script that rotate any texture, but it's difficult...

CadFather

Matt, you are a gentleman, but (promise) don't waste your energy if too complicated, this thing can be addictive!

Matt666

Yes, I noticed it...

See here and here, rotate a texture is an old challenge for me

But NewOne seems to be THE man for this ! I often ask him for texture advices in ruby. The big matter is I am crap in trigonometry...

See you soon !

CadFather

..trigonometry? what's that?

sometmes i think there should be a ruby basecamp - on mount olympus somewhere!

Well, ... I just dived into SU ruby because I wanted to create a ruby that mirrored the texture from the front side of faces to the back side of faces.

I've been digging in the docs to try to work out how to position textures. I only managed to position a texture in 2d reliably. Even then I'm not sure I'm 100% sure what's happening. I haven't managed at all to get any info from the front face UV co-ordinates that makes any sense.

I had hoped that I'd find some good info on this forum. But seeing that the general consensus on SU Ruby texture mapping is confusion I'm now worried to what task I've let myself into.

I'd like to try to prompt some of the SU dev team to shed some light to this matter of UV coordinates.
