Materials permanently change, dragging material without releasing mouse button

I have not been using KS5 Pro for long.  But I just noticed on a larger assembly model that when I drag a material sphere/swatch over the model and it starts to preview the materials changing, the materials will stay changed even though I did not release the left mouse button.  I thought this was a graphics update glitch.  But when I save the model, closed and reopened, the materials were changed.  Also, undo is grayed out so you can't undo.

I'm trying to only use the scene tree because of this issue.  But if you are zoomed into your model, you can't even touch the model while dragging the color sphere over to the scene tree.  I try to drag around the perimeter of the menu so I don't touch anything.  Sort of a pain.  I did not have this problem with KS4.

PC, Windows 7-64, KS Pro Floating 5.3.6, Model exported from Creo 2.0 with KS5 plugin.
Happens on two different computers: one with AMD Firepro W7000 and one with Nvidia Quadro FX 1800.
Steps taken:  Rebooted, reloaded model, tried some KS preference (interface, advanced) settings.

Hi Mike,

Just tested this out on my end and worked fine for me. Tried with a couple of different scenes (one from Creo). Try switching over to performance mode (as the material update may be slow with heavier scenes). Next drag a material over and don't release. It will switch the color around to preview but you can pull the material off so it doesn't apply (move it back to library, hover over background or hit Esc on the KeyBoard to cancel the material application). Also, I am able to undo the material change, so I am curious what may be happening on your end.

You mentioned you noticed it on large scenes - is it only happening on specific scenes then or are you able to repeat this on any of the default scenes that come with KeyShot?

Hi Chad,

This materials glitch does not happen with any of the stock Keyshot scenes.  But they are all pretty small compared to my assembly.  The scene is about 700 MB.  I can't send it for testing due to client confidentiality.  I did make a short video of what is happening.  I'm not sure if I can upload video here.  Let me know if I need to email it to you.  I never released the left mouse button.

I did try a couple large models created with KS3 or KS4 and the Creo KS3/KS4 plugin.  They work okay.

Thanks for the video, Mike. I see that it's certain parts from a scene from Creo that has the issue - are these parts native Creo part files or dummy parts from another program?

Have you tried importing the assembly instead (not using the plugin) to see if that makes any difference?

I have not tried to import the data directly.  The reason is the plugin allows me to control the model visibility and choose a simplified rep.  If I save out a STEP or open the native Pro/E model, I get the entire model and all the construction geometry.  It makes the model extremely large (2 or 3 GB) and I have to remove lot of construction surfaces and skeletons.  Most of the solid models in the assembly were built in Pro/E, Wildfire, and Creo.  A few parts are imported STEP or surface models. 

I found the material change to be random.  I can do the same thing and get different results on different parts.  My work around is to just to drag to the scene tree.  I'll try to test more large assemblies and post my results.  The glitch may be isolated to this model because it does the same thing on three machines using different graphics cards.

I get this all the time on my iMac - I have to be very careful and if I drag a material fro the left panel I have to ensure my route to the tree is via the bottom of the keyshot window so as to avoid brushing past the model.

Sometimes when busy I forget to check and render out something with sudden incorrect materials applied :-(

I don't know if this is a fix or not.  But I reverted back to the KS4 Creo Parametric plugin and I no longer have the problem.  I can drag materials directly onto the model without it freaking out and randomly applying materials .  It seems like larger models generated with the KS5 plugin were the issue.

Not sure if this will help you but, in one of the latest Webinars for Material Control (great webinars BTW, thanks Josh and Dries) it was mentioned that you could undock the Project pane/window and move it next to the Library pane /window to avoid dragging the material over the real-time render window. Having the panes next to each other makes it easier DnD (Drag-n-Drop) materials on the scene tree.

It would be nice if the window docking positions could be selected to next to each other rather than on opposite sides of the screen when Dock Windows is selected in the menu.

You can export your simp rep as a Step file. Just activate your simp rep and erase 'em from session - then export the asm as step.
May that help?!

Or you can use ks6, than you can lock the different parts for unwanted changes.
