When installing new plugins or updates to plugins they always write a new plugin.ini entry. This may be the plugin devs fault but I also think it is a Max issue by having two plugin.ini files. One in the root and one in local. Just another small waste of time to clean it out. Seems I am doing it once a week sometimes.

I currently have approx. 10 plugins with as many as 10 Help File entries for each one. Yes I like to RTFM :)

As described above.
Tested on two innstances of 3ds max.
You can't scroll down in any way - and if you want for example use "link constraint" within one of many CAT layers, you can't !

2012, spline creation and zooming is far, will result in dialog box asking: "close splines: Yes No". If clicked No: zooming doesn't work anymore. Why does this dialog appear out of nothing while zooming in spline creation?

*.bat file does not start to render scene from Windows. It's just flashes and dissappear

Why, why, whyyyy ? ? ?

Using the saturation control in max produces really odd results, for more information (including lots of pictures), please visit this site:

The resource collector often does not collect and leaves behind many texture maps. Despite the "collect bitmaps/Photometric Files" box being checked.

For example I use Zbrush with GoZ a lot. When you create displacement and normal maps and GoZ them over they stay in a temporary Zbrush folder until you move them manually.

When I use the resource collector on these scenes it often misses those maps.

If you turn off Real Time playback in the Time Configuration, in most cases the viewport will not play the animation.

When I render an object Id or z depth often the reflections in the scene get messed up. So I have to render the scene twice to get everything I need. This costs a lot of time.

I use Bridge all the time, and it just doesn't work with the Use Last modeling button. Connect works fine, collapse works fine, but no love for bridge?

When rendering using backburner and using stripes, the images get gamma corrected twice, because the render of the stripe is already gamma corrected and then, the pass of stitching the stripes together applies gamma again...

When desktop composition is enabled in Windows 7 (and probably Vista), the quad menu lags when right-clicking the viewport (just long enough for it to constantly disrupt my workflow). Now, I'm opening the quad menu a LOT, so you can imagine what a pain this is every time.

For now, I have to disable and re-enable desktop composition from Window 7's "Performance Options", but it'd be REALLY nice to have this irritant fixed.

Make 2 points, link p2 to p1. Assign a spring controller to the second point. Add a couple of keyframes to p1's position to get the spring moving. Save the file. Merge both objects back in. (keeping same name) p2 that got merged in will now be driven by the original p1 even though it's still linked to p1 that it got merged with. Workaround is that the object with the spring controller needs to have a different name than the one that exists in the scene

Track view translate keys left/right translate keys up/down features no longer work in 2012. CTRL drag locks still work.

Nitrous viewports frequently stop working under Windows 7 (64-bit). A guaranteed way to make this happen is to turn the monitor off and back on (using a monitor connected via HDMI or DisplayPort), but sometimes it happens during rendering as well (viewports no longer work after rendering is finished). Seems to happen more frequently if the user Alt+Tabs to another window or to the desktop. Currently, the only solution is to close Max and restart. Please add a menu option to reinitialize the viewports, so we can at least recover from this bug.

When trying to select a key (subobject) on the trajectory to move it, if your timeline is offset the key selection will be off by that much. For example if you have a trajectory and have a key on frame 0, 5, 10 and your timeline is set to 2-100 when you click on and select the keyframe subobject on the trajectory for frame 5 it will actually move the object on frame 7.

Probably a one or two line fix for a simple little thing to correct for the timeline offset.
