Can any Mac users verify if this script is working on SU 7.1? It appears to working great on Vista, SU 7.1 but I still have a report or two of it not working.

Anyone have any example files where it is not working for them?

Thanks

Chris

SU 7.1M1, OSX10.4
A´OK!

Chris Fullmer

Thanks Thom!

I should mention what is not working for some, just in case you just verified it loaded.

I have heard 2 or 3 reports of this plugin thoring components all over the place, instead of using their axes. It seems that for some, this plugin does not scale and rotate according to the specified axes.

So if anyone still feels like testing further, awesome. Otherwise, I'll write a debugging version and give that to anyone who wants to test it out, see what is broken on their system.

Thanks again,

Chris

I just tried the random rotate and scale. That worked as expected. But if you have specific procedures that's reported to fail, then I can try that.

Pixero

Yeah, I've seen that two times recently when using axis.
When I choose component base everything was o.k. though.

Chris Fullmer

Has it been on all components? or is just on face-me perhaps?

thomthom

I tried with groups, components and face-me components. Can't reproduce.

...maybe it has to do with nesting..?

thomthom

just noticed something when orbiting after random rotate and scale; face-me components float about all over the place.

thomthom

that also occurs on PC.
See attached file for a sample of dancing Sang!

great. thanks.

this is exactly what happens with me. as you orbit they scatter all over the place.

Chris has found this to be a bug in SU. He'd working on a workaround.

Chris Fullmer

Yes, this was an interesting bug to track down. It includes a few steps to get around it, but I have it working. I just have not been able to find time to work it into this script yet. And when I release it I'll owe a few big "thank you's" to a bunch of helpful people out there.

Chrisssss! I used your plugin on a forest of faceme trees - quickly found myself in a mad frenzy of trees dancing ghostly around.

Update? pretty pleeeease!

My idea of making its faceme false doing the rotation then resetting its faceme back again should be easy to include ?

I just tried to use the Console to turn off then on:

sel[0].definition.behavior.always_face_camera = false
Scale and Rotate Multiple
sel[0].definition.behavior.always_face_camera = true

But still got the same problem.

Chris Fullmer

Hi Tig and Thom. Sorry I still haven't updated it. I've got the code all worked out, just not put into place. The issue is 2 fold - 2 different bugs at play. TIG your trick helped the part that faceme's components bounding boxes ( bounds.center ) no longer return the center of the component. The return center of entire range of motion. Which is not helpful. So I used your tip to make the faceme into a regular component, then grad the centerpoint and then I have the point to scale about. So it helps find the scale about point which is otherwise impossible since v7.1.

The dancing and jumping is another bug. You can no longer use ANY of the uniform scaling transformations on faceme components. It sort of cheats, and just adjusts the 16th matrix element. So the 16th should always be 1, but if you use (which I did) a uniform scaling method, it will change that 16th element to act as an overall scaling factor, which freaks out faceme's in 7.1.

So if you want fix it Thom, you would need to change the faceme scaling method. And I don't have the code in front of me, but it should scale by something like this:

sf = (the scale factor, as a float)
t = Geom::Transformation.new(sf,0,0,0,0,sf,0,0,0,0,sf,0,0,0,0,1)

That should scale a component uniformly by aplying the scale over the entire matrix, and not just adjust the 16th element.

Or I'll try to fix this later today (but it might be well after midnight in your neck of the woods Thom).

Chris

PS - I know very little about transformation matrices. So I apologise if I used incorrect terms or theories

thomthom

No worries. I'm home now - and only have one day left before I take Christmas holiday.

Though, in my tests for uniform scaling of a faceme component 2x, the 16th turned into 0.5 and 13-15 also halved their values.

Chris Fullmer

Woohoo! Thanks to lots of persistence by others asking me nicely to get this one fixed, and thanks to finding the problems by Thom and Edson, and some great solutions by TIG, Jeff99, and others - I think I can finally say that this script is updated and working with SU 7.1!

Well, hopefully. Please test it when you get a chance. I tried every combination of faceme and regular component scaling I could think of.

v2.5 - SU 7.1 compatibility fix

Fixed scaling so that Face Me components don't freak out like they have been doing since SU 7.1 was introduced. Big Thanks to Edson and Thom for helping figure out what was breaking.
Cleaned up some code - a big chunk thanks to a tip from TIG!

So if you have this script installed already, go back to the first post in this thread, and re-download. Then overwrite the existing file in your plugins folder. Thanks, and I hope this works now!

brilliant! another Christmas Present! thanks a lot, Chris

Wow thanks man, you are very creative with your scripts, they are very useful and easy to use. Thanks!
