Vertex color+envelope=crash

[rray]

Hi

I run into this bug quite often, can anyone reproduce before I send it to support?
Run this Javascript code, subdivide the cylinder once, and then move null1 - it should either crash or you should get some weird mesh behavior

Thanks

Code: Select all

CreatePrim("Cylinder", "MeshSurface", null, null);
SetValue("cylinder.cylinder.radius", 0.15, null);
SetValue("cylinder.polymsh.geom.subdivv", 55, null);
SetValue("cylinder.polymsh.geom.subdivu", 55, null);
GetPrim("Null", null, null, null);
GetPrim("Null", null, null, null);
SelectObj("null", null, null);
Translate(null, 0, -2, 0, siRelative, siLocalSymCOG, siObj, siXYZ, null, null, null, null, null, null, null, null, null, 0, null);
ParentObj("null", "null1");
ApplyFlexEnv("cylinder;null,null1", null, 2);
SelectObj("cylinder", null, true);
CreateVertexColorSupport(null, null, null, null);
PaintVertexColors("cylinder", [0,1,2,3,4,5,6,7,8,9,10,11,12,13], [0,1,2,3,4,5,6,7,8,9,10,11,12,13], 1, null);
FreezeModeling(null, null, null);
SetDisplayMode("Camera", "shaded");

Hello,
I just run your script on SI2014, subdivide cylinder and move null1.
It doesn't crash on my side and mesh behavior seem's good : see screenshot below :

I hope you can find a solution.

Hi there,
thanks for checking,
should have been more clear sorry, I meant subdividing using geometry approximation ("+" key once).
That's good, I'll modify the bug report so this is more clear.
What's weird too is, the bug doesn't happen when the subdivision is done inside the script (IncreaseSubdivision command)

You're welcome.

Ah ok, just retest with "+" subdivision and I have not crash : see screenshot below :

Maybe I'm just lucky ;) ...

Oh that's only on my side then, maybe I have a graphics card issue. I thought it was not on the graphics card side, because I remember having the same issues with my old card (gtx 460, new one is a gtx 660)
Will try some driver updates before I submit the bug (if it's even one)

Tnks again

edit: on my old pc it works without problems too..

SoftImage 2012 SP1 64bit Windows 7 64bit

Does not crash, but geometry looks like it would like to crash

Thanks for checking wolfgang, that's exactly the same glitch I got.. with some other geometries it crashes

I tried with Softimage versions I have in this PC and it went OK in all of them.

2014 SP1
2013 SP1
2011 SP2
2011 SP1

Windows 7 Ultimate
GeForce GTX 650
Driver 314.07

Since I started to have some weird glitches and even crashes when starting Softimage (I mean, it crashed before even start the viewport) I only use this version (314.07) that was recommended in the Autodesk website:

I think they have newer driver recommendations
