odd blender 2.49 UI problem

[bnewton81]

Ok, I have noticed that this UI problem happens much more often in proportion to the amount of things on my screen. I mean that it won't happen until I have a considerable amount of verts, but the more verts I have the worse the problem. I'm working with Zuri on an age and when I load it into blender and rotate the view, the manipulator handle and everything jump in and out of perspective. This REALLY sucks, because Zuri has done everything in 2.49 and we have to use 2.49 to "publish" the ages to uru.

If 2 ppl on this small forum have the same issue then, this can not be all that uncommon a problem, but when I search google all I find are my own posts in different forums; and now with 2.6 out I know that my chances of ever finding a solution are nill.

Its still not clear to me what exactly happens on your side.
Do you have these problems in object mode or in edit mode?
In edit mode i have seen that vertices " snap" to each other depending on the distances from the world center.
often this can be avoided by editing the object in local view only.

When i look to the youtube film, i get the impression that you use wrong blender settings.
What i see there is turntable view(around the world center).
What we want is an object rotation around the object center as a trackball rotates around its own centerpoint.
The correct setting can be seen here:

Well, not quite. The difference between trackball and turntable, is simply that the former allows for free motion, whereas the latter (which is my very very much preferred mode) has one axis locked, so that up is always up.

What you refer to, is rather the the "Around Selection" button, below the "Turntable" one.
(EDIT: If it is ticked, rotation will be around the medium point of everything that is selected -- if unticked, rotation will be around the 3D cursor.)(EDIT2: Ok; NOT around the 3D cursor - the pivot point is separate and unmarked - there I get for writing about something I never use :)


Glancing at the first post again and trying to understand what the problem is, it sounds quite possible that bnewton's problem lies with the one remaining button in that group: "Auto Perspective" will automatically switch between ortho and perspective, when you change to a top/front/side/opposite_either_of_those (cardinal) view (auto switch to ortho) or look around (auto switch to perspective).

( Btw: Everybody knows that the "." button on the numeric keyboard centres the view on the current selection, right? :)

Ok, what happens is that objects on the screen twitch out of location when rotating or scaling. Also I just noticed that the mouse cursor isn't being drawn in the location which it appears to be in. Like I try to select an object and nothing happens or I press BB for the brush select and the circle is 2 inches to the right. I'm going to try to get it working in linux and I'm fairly confident it will fix the problem, but it will still be a pain in the butt to switch back and forth. I'm not even sure I can use my textures in linux.

I've been at this issue for months. Such a pain.

Well made some headway. Found that if I use the onboard gfx there is no problem with blender, but I can't switch every time I want to do something in blender. Also, this is strange, if I open a 2.49 age blend in 2.61 and then save it, and then open it in blender 2.49 the gfx are fine. Very strange. the gfx are fine in every way after that. Is there a way to do the brunt of the work in 2.6x then only use 2.49 to do all the PyPRP things? What is untransferable from 2.61 to PyPRP 1 and blender 2.49?

Last shot: did your ATI drivers perhaps sneak in some dodgy friend to the party, akin to NVidia's "nView Desktop Manager", which adds some bells and whistles to Windows' standard GUI and which can be disabled?

Finally i know how terrible your " popping in perspective is", because i have seen it on my own PC.

I Know it after i did a fresh w7 install with a ssd as primary disk.
Blender was working fine, but as soon as i installed the ATI console with the latest drivers. it became nearly impossible to do anything.
When i zoomed into an object suddenly it was in perspective view. by the next mouse touch it was in ortho again.
So on and on and on.
Impossible to do any editing.

I never had seen this before.

I have tried everything which you can change in the console window, without success.
Then i deinstalled the update to those drivers.
When finished, blender was slow, sloooo.....w.

After that i decided to use system restore to a few days back in time.

ahhh, all problems gone. i am happy blendering again! without this annoying issue.
I don't know, and probably never will know what went wrong,but it is clear that you have to use the driver which is delivered by microsoft.
That driver is nearly as good, but does not support the last new game developments.
" Anteworld " world( for instance) won't work with the microsoft driver, but most others will do,
so it is a compromise we have to take.

I know now, that native microsoft drivers work with blender 2.49b and ati's latest do not (always).
