[Plugin] UV Toolkit

I don't quite remember what I did. But what I do is somewhat special for quad-faces with textures stretched to fit.
Think you need some different handling for a general rotate method...

Jim

It works for square textures (where the image is square) but distorts rectangular ones.

thomthom

I think what you need to do is sample four points in a quadratic formation of the face's plane and then shift the 3Dpoints.

That's a mighty small image there... can't see much what's going on.

The rotate feature is meant for textures stretched to fit quad-faces. Special purpose rotate. SU already got rotate methods built in - When you activate SU's texture gizmo - you have a Rotate sub-menu.

Here's my two requests for a great tool:

First, an option to keep the scale of a texture when rotating.

Second, add it to the right click menu for easier access.

Edit: Fixed the image size.

Pixero

Still its great to be able to select a bunch of faces and rotate at the same time.
You cant do that with SU's build in tools can you?

No you can't. Good point. I could add that feature.

Pixero

I'm using it to rotate the texture on leaves on trees so doing it manually isn't an option.

And don't forget the right click menu...

thomthom

Only thing though, about which points should it rotate...?

Pixero

Can't you just swap the UV "scale"?
I mean like it is now but with an option to keep the scale on the X and Y axis.
(Rotating the points so that Points A,B,C,D would be D,A,B,C or something like that.)

thomthom

There is no such fixed points. The one for the quad-faces works like that because you can use the four vertices of the face. But you can't do that when you have differently shaped faces and/or want to preserve scale.

With SU, you have to generate the set of points yourself and query the face. So when rotating, I need one anchor point.

thomthom

hm... or maybe it won't be a problem.... hmm

Pixero

Ok, what would you suggest.
Center of face? Or a window where you can choose like in Profile Builder?

thomthom

That's the thing: what would you determine as centre of face for something like this? (or top,left,right,etc...)

Pixero

Center of bounding box maybe?

What kind of a quad is that, Thom?

thomthom

The exotic kind.

My point was - that when you don't deal with regular quad-faces - it's much harder to predict desired result.

thomthom

The thing is - would picking the "centre" (however it's defined) be any different, as just picking the first vertex I can get? At all seem rather arbitrary in terms of the result.

Would it be possible to have an option for it to automagicly recognise the lenght direction based on witch side is longest on a quad and rotate it to match that.
Like if I want to rotate some UVs on a branch to line up the texture with the trees branches length direction. Would be cool.
Am I making myself clear?

Are we talking about rotating on quads strictly? I was under the impression this would be a general purpose rotation.
