Rotation vs scale

[neo0.]

Hi, I trie to look this up in the manual but there wasn't an explanation of it, so which one is rotation and which one is scale? It would be nice if indigo had an auto uv feature. Just saying.

2x2 matrix?

Illegitimate into an UI !
IIRC scale are top-right and bottom-left values (together for uniform scaling), rotation is above my head to explain, you need sin and cos calculations lol.

Rotation 90 degrees is of course:

0 -1

1 0

180 degrees:

-1 0

0 -1

270 degrees:

0 1

-1 0

For all other angles it's

cos (α) -sin (α)

sin(α) cos(α)

But it is of course not very intuitive, especially if your knowledge in linear algebra is a bit rusty. I quite like the advanced mode checkbox for HDRI's, would be great to have the same option here.

I hope we get some nice, clear controls for 4.0!

Hope to also see an option to scale textures uniformly (e.g. scaling the diffuse also bumps up the specular or something). Thoughts?

That's probably better to handle with material nodes when/if that comes to Indigo.

I still heave no idea why people want to do such changes inside Indigo GUI!?
My 3D Project inside my 3D app is my main sourcefile, all changes and alterations should be inside that file,
I work on and with that file until the Project is finalized, and if a customer wants some changes I open this files to do these.

I understand that some quick material changes inside the GUI are awesome to test parameters,like for example bump strength or IOR of a material. If I found something good, I port it back to my sourcefile, but changing the scale and rotation of textures?? This is something that should be doable within the Viewport of every 3D app!

Or am I the freak here with that workflow???

I agree, UV mapping belongs in the 3D app. I believe this has been discussed many times already? Sure, in some rare cases you might want to rotate/scale a texture quickly but even if we had a better tool for that it'd become obsolete when we get tighter 3D app integration.

That is exactly my point, such discussions about features that cost dev time, clutter the GUI and only get used my a fragment of the userbase even once seem to come out of some deep trollcave that somehow is impossible to close

Nope. Having the same here.

Not a freak, same here. Source(app)->Indigo. Everything is set inside. Using Indigo for what should be done inside app, such as UV-ing, seems insane. I just wish exporters were integrated more.

soooooo can we finally close that cave once and for all instead of throwing food inside, these discussions get boring and tedious...

Trying to do it the same way - appropriate tools for specific objectives.
