1. Updating the first parameter of jit.gl.multiple causes attribute reset

2. Positioning differs with factor 50 from regular jit.gl objects

I can reproduce with jitter 1.6.3 b1 on OSX and 1.6.2 rc1 on XP.

1. Updating the first parameter of jit.gl.multiple causes attribute reset
and drawing.
2. Positioning differs with factor 50 from regular jit.gl objects

I'm unable to reproduce but that doesn't mean there aren't bugs. Can

you post the steps needed to recreate the problems you're

Hi Thijs,
I'm unable to reproduce but that doesn't mean there aren't bugs.  Can
you post the steps needed to recreate the problems you're
encountering?

I tried the updated version of gl.multiple, but it didn't change anything. I

tried to make the patch a little more clear. Hope the one below makes more

1. If "position" is the first parameter/ inlet. to gl.multiple, updating its

values causes the instance to draw, and also to reset attributes like scale

and position for that draw. So if you set @automatic 1, you get 2 drawings,

one correct triggered by the automatic mechanism, and one with reset

attributes triggered by the matrix input on gl.multiple's first inlet.

2. The position parameters for jit.gl.multiple seem to be x50 compared to

other gl.object. If I use the coordinates from the position matrix to draw

separate regular gl objects instead of using multiple for that, I have to

divide the position coordinates by 50 to get the same results.

values causes the instance to draw, and also to reset attributes like scale
and position for that draw. So if you set @automatic 1, you get 2 drawings,
one correct triggered by the automatic mechanism, and one with reset
attributes triggered by the matrix input on gl.multiple's first inlet.

2. The position parameters for jit.gl.multiple seem to be x50 compared to
other gl.object. If I use the coordinates from the position matrix to draw
separate regular gl objects instead of using multiple for that, I have to
divide the position coordinates by 50 to get the same results.
