 when operating in an exported runtime (standalone) on 

. I tried to find the object in the Max application itself to copy it over manually but to no avail. Does anyone know the backstory to this, where I can find the object, whether it cannot be used in projects which will later be rendered as standalones or whether this bug is already known and being worked on?

I've been working on a set of Max for Live devices that rely heavily on JavaScript. Recently, I've been having some issues where the adding the devices to an empty Live set will instantly crash Live. Sometimes, Live will display an error that says "A serious program error has occurred. Live will shut down after this message box is closed." In other cases, Live just abruptly quits.

After doing some bisection testing, I found that the crashes were specifically being triggered by jit.gl.texture objects receiving bangs on load. Opening the Ableton crash dumps in WinDbg revealed that the last instruction preceding the crash was always jitlib!jit_handle_size_set . This led me on a bit of a wild goose chase trying to figure out if the issue had to do with initialization order, GL context creation, etc.

I noticed the problem would persist for a while, including across rebooting my computer, and then it would seemingly "fix itself," which led me to suspect that it was being caused by a file somewhere on disk rather than anything stored in memory.

I thought that the issue was perhaps being caused by the Max's database files for Live (at AppData\Roaming\Cycling '74\Max 8\Database or AppData\Roaming\Cycling '74\Max 9\Database, depending on your Max version). Deleting the files in these folders seemed to fix the issue, but now it's cropped up again. I initially posted this when I thought I had a working solution in case it was helpful to anyone else, but now I think I'm just going to submit a bug report to C74 support.

 in this patch show the expected results, both the Kalider-direct output and the "txKalid" texture output show the noisy Kalider colors.  But, the 

 window showing the 3d output of the "colorCrossfader" shader is not showing those Kalider texture colors, even though coded to do so.

color = mix(txKalidVec, color, colorOffsetScale);

//color = mix(txChixVec, color, colorOffsetScale);

output the exact same colors (crossfade results) when you swap which line is commented out.  In other words, it seems to me like the "txKalid" texture reference in the shader code is pointing to the "txChix" texture's memory location instead of its own memory location.  Could that be correct?  Or, where is the mistake I'm missing?

Edit: moved thread to Jitter category.  If you remove the @shader attribute from one of the gridshape objects, the "default shader" for that object does a 50/50 "blend" of the two @texture inputs in 

, so I think I should be able to control that "blend amount" in my custom shader with the "colorOffsetScale" parameter value.  But, not working.  Is it me? It's usually me.

Hello everyone, i'm having a problem using jit.gl.multiple. I'll explain it.

Take a jit.gl.gridshape bound to a jit.gl.multiple (through left jit.gl.multiple outlet):

jit.gl.multiple @blend_enable appears to be useless, i can't see any variations changing it. 

Case 4. shows that is possible to work with both light and alpha channel activated. The problem is that I want to change A channel with jit.gl.multiple and not with jit.gl.gridshape while having light_enable 1. If I could modify alpha channel with jit.gl.multiple while light_enable is 1, it would give me more possibility to change it individually on each copy made with jit.gl.multiple, unless to do it globally. I can't figure out how to do it. I hope someone can help me.

I'd like to report a problem I've been having lately on dozens of different desktop/laptop with Windows 10/11 and laptop Mac Intel, with Max 8.6.5 and Max 9.1.1.

I initially thought it was due to the complexity of my patches or the size of the textures, but below is a 

 patch that shows the same error: a simple rectangle that scrolls from left to right once a second, the jit.world bang calculates its position, sync on, 60 fps.

The issue appears after a short time (usually 

, then performance returns to normal. After some time, the problem repeats.

Note that on Windows jit.fpsgui always reports a stable 60 fps, and I haven't found a way to check these dropped frames from within Max.

The only way I've found to objectively check for dropped frames is to use an HDMI to USB-C video capture card on another computer and calculate when there are duplicate frames.

Is this a known issue related to jit.world, internal scheduling, or the rendering loop?

OS-level GPU scheduling or power management?

Are there recommended flags, attributes, or diagnostics to better understand these periodic drops?

I have a fairly complicated jitter patch that receives a lot of OSC messages from a Pure Data audio installation. Briefly, it is composed of 8 gridshape that goes to 8 mesh that goes to 8 nodes that are blended to two spout server and I'm using Resolume to edgeblend this composition on a three projector screen. All data from the Pure Data patch are mapped to some parameter to do an audio - video reactive installation. It is working very well at hight fps, but : 

Randomly, I get these errors, always new random ID for both : 

name u709007696 already in use. ob3d does not allow multiple bindings

Also, the patch randomly closes/crashes without having a crash report on reopening.

Is someone here knows why I get these errors and if it could be related to the crashes?

I'm using the viddll engine in order to trigger jit.movie video playback with very low latency. Loading a video into ram with the "loadram" message does indeed allow me to trigger the video very quickly, but it also causes a spike in CPU usage, getting as high as 100-200% after loading just a single 4.2 MB 720p video. I have a patcher with several jit.movie instances that use jit.movie's @moviefile attribute to load video files and it reaches over 800% CPU when using viddll—and that's without any videos actually playing!

In addition, in spite of following Rob Ramirez's advice on viddll best practices (
