SU crashes, when creating a light

[jo-ke]

Now it is the thrid time, that su crashes, when creating a light in a scene. I was working a bit fast, may to fast for the plugin?

it always happend after the third and last click, when creating a light

That sounds quite frustrating. Which version of the plugin, specifically, are you using and on what operating system?

I am working on

WIN7 64bit
SU2015 15.3.331 64bit
Twilight 2.0.4 (M2)

seems to be not the latest version of twilight.

I'm going to download it...

Do you have SU2LUX installed? There have been reports that SU2LUX does things when new materials are created and because of this, when a new light in Twilight Render is created (which creates a custom material for that light), it causes a crash. I don't know what SU2LUX is doing in response to a new material, but it seems to be causing a crash.

[jo-ke]

no I don't have it.

I will report it, if it happens again with the new version.

What plugins do you have installed? It could be a problem common to more than one plugin (especially when plugins are built against the same basic "framework").

[jo-ke]

these are my plugins:

So quite a lot.

My guess is that one of the plugins is doing the same thing we have seen SU2LUX do, which is delete and replace ComponentInstances. When Twilight Render creates a light component and sets up the material on it, if one of the plugins is deleting that instance and replacing it, the ComponentInstance that Twilight Render is trying to work with is no longer valid (and SU crashes). If you are able to determine which one (if that turns out to be the case), that would be very helpful information.

copy the current plugins folder, and rename the copy to be plugins-orig
then open the plugins folder and delete all the plugins so that the folder is empty except for Twilight Render
restart SU and test. If it is no longer crashing, copy half of the plugins into the folder, and test again.
If it crashes now, then you know one of the plugins you copied in is the problem plugin. Delete half of them, and test again.
If still no crash, put half of the remaining plugins into the folder, and so on.
This is the quickest way I know of to find the troublesome plugin... test half the plugins, at a time - then test the other half.

Hope this makes sense, it's difficult to explain, but easy to do.
