I'm trying to apply a feedback effect (with a jit.gl.pass) to a content created with jit.gl.mutiple and two jit.gl.gridshape with different 'name' attributes (i'm using the targetname attribute to draw them). When I'm not using the jit.gl.pass, the two jit.gl.gridshape are correctly rendered through the jit.gl.multiple. But when I'm trying to apply the feedback with the jit.gl.pass, only the last jit.gl.gridshape wich had been called with targetname appears.

Am I missing something or am I using the wrong method ? How can I apply the feedback to the two jit.gl.gridshape ?

Thanks for reading,

your patch is incorrectly using both automatic mode and non-autotmatic mode drawing of the gl.multiple. pass effects require automatic mode drawing.

while you can bind a jit.gl.node to a jit.gl.multiple to draw multiple shapes, the scaling transformation is different. the shapes are basically scaled "in place" leaving the same distance between individual shapes, contrasting with your patch where distance is scaled as well. I'm not entirely sure why that scaling effect differs, but if you need this behavior just draw with 2 jit.gl.multiple objects.

The patch using the jit.gl.node is exactly what I needed.

Thank you for your help !
