xLights crash on render & DMX light beams not showing

[ericw]

Hello!

xLights wants to crash on render. This has been happening since v2020.2. My only display changes from 2019 to 2020 have been going from a P10 matrix to a P5 matrix. Layout & Universe counts have been updated to follow suit.

Replication:
I open xLights (Currently 2020.23 x64), open my sequence, hit render, and wait. It almost gets to the end of rendering (like 90%) and then dies. No crash popup either.

I have also noticed from v2020.2 that while in the layout tab the DMX Moving Head 3D beams do properly show up, but neither the beams appear nor do the heads show they are locked into their positions during playback. It has me think this is due to the rendering fail. Even when clicking on any effect on any model, causes a crash with no popup.

These issues can be replicated on my sequencing computer and on my work computer.

Something tells me that my RGB_Effects is corrupt. The fear of starting from scratch is real y'all.

Thanks!

This will not crash in .24 but I am less sure the fix gets you the result you are after, Take a look at it when it comes out and let me know if there are more issues.,

I have downloaded .24 & rendered 4 different sequences now. The crash on render problem seems to be fixed. However, you are right. the DMX fixtures still do not respond. My models are shown as the "Moving Head 3D". IDK if that has anything to do with it. Even with that still broken, at least I can get back to doing some sequencing again!

I didn?t know what you were trying to achieve so I am not sure if there is a bug here or a setup error. I suspect the latter.

Since the new version of xlights I've noticed that if you had set up DMX Moving Heads using the old 3D MH model then they show up weird if your layout is in 2D. Either redo your DMX fixtures with the new types or change your setup to 3D

Here is a 2 minute screen capture explaining exactly what is going on. Also attached are the log files for this sequence. One thing I didn't mention in the video is that the crash on render is fixed. So my bug is now 50% fixed.

Yes ozaz is correct.  You need to change the model.  When I first broke up the DMX models to their own classes I had it converting the old 2D head that looked 3D into the 3D model thinking it would draw and look ok in both 2D and 3D.  I can't remember why but trying to let that 3D object draw in 2D didn't work out so we really need to make it so sequence upgrades leave that model type alone and don't try to convert it.  If you put it back to a normal 2D DMX model and switch the type to 3D it will look like it used to.

I am having a hard time understanding what needs to happen in order for the model to function. I have added both a "Moving Head 3D" and a "Moving Head" under the DMX drop down in both 2D & 3D modes. And when I add a "Moving Head" in 3D mode and switch it's type to "Moving Head 3D" it doesn't even draw a fixture. In layout mode it shows a brown box and in sequencer mode, nothing is there. Also, in 2D the fixtures appear as a red box with an X in it.

It's Moving Head in 2D mode then the very first property is DMX Style which you change to Moving Head 3D.
