GL Tools 1.4 crash in Music Visualizer Please find quoted below the resulting crash report when iTunes ducked my CLGL variation of the Arabesque screensaver as a music visualier. I am going to dive in and take a look at what I've changed to provoke this error, seems to be one of the presets alone, all others run AOK. GLTools got mentioned in dispatches as follows :- Process: iTunes [1936] Path: /Applications/iTunes.app/Contents/MacOS/iTunes Identifier: com.apple.iTunes Version: 9.0.3 (9.0.3) Build Info:

First sigill of this year BTW :-) .

Well, then, happy new year!
Which GLTools patch(es) are you using which have structure inputs? What are you feeding to the structure inputs? (The crash seems to be happening when GLTools attempts to dereference an input structure value.)
Thanks for the response.
Arabesque does have a Macro that generates a circle. Within that macro I have placed -
Cube Structure Point Structure Line Structure Quad Structure * 2
These are fed a mesh generated by using a slightly modified version of the Structure to Mesh macro found in the SL Aurora code sample.
The Structure to Mesh is fed a queue of audio Peak data, as this type of audio data works less prone to crashing than using the straight Spectrum queue, even if smoothed by scripting.
Find attached both the composition in question with a multiplexer -arrow key up to change Mesh input and without a multiplexer.
0 sends the Structure to Mesh, 1 sends the Mesh Jiggle version.
It seems the Structure to Mesh being fed straight through causes the problems.
Hmm, both of those compositions work just fine using GLTools-1.4 on my system. And the composition is huge so it's going to be difficult to narrow it down, especially since I can't reproduce the issue.
Can you build a simple composition that triggers this crash?
So far I've tested GLTools using both imported meshes and generated meshes (generated using the
Mesh Creatorpatch, like Arabesque does), and haven't experienced crashes or other unexpected behavior.Simpler composition is in process, but thus far I can't reproduce the crash that the non-filtered Mesh variant previously posted produces for me.
