What I want to do is to use it to grab a series of images with alpha channel and use them into a jit.gl.multiple 

My main problem was to keep the alpha, which, somehow, gets lost.

But it's not always the case, sometime the transparency works, sometime not...

Now, another strange thing I ran into is the name of the captured textures. Sometimes they stay the same sometime not.

I need them to stay the same to be able to display the one I want on the jit.gl.multiple instance I want.

So, my questions are, when you open the attached patch.

In general, if I want to use the textures in a node, should jit.gl.textureset draw to this node or to the main context ?

The alpha seems to work but I get "jit.gl.texture: bind: GL Error: Invalid operation" each time I capture a new texture.

Hi,
I'm struggling with jit.gl.textureset.
What I want to do is to use it to grab a series of images with alpha channel and use them into a jit.gl.multiple inside a node.

1_Is the countdown transparent ?
2_Are the textures name changing ?

I am on windows 10, Max 8.1.8, gl2

I tried with gl3.
The alpha seems to work but I get "jit.gl.texture: bind: GL Error: Invalid operation" each time I capture a new texture.
And the names keep changing.

the countdown is transparent (MacBook 2013, Catalina)

Texture names are changing, because there is a mismatch between the list lengths (zl.group, counter) and the loop condition of 

// only output if tex had been initialized with a capture

if(texset[a].name.indexOf("_cap") >= 0) {

outlet(0, "jit_gl_texture", texset[a].name);

Set texturecount to 6 and it will stop changing.

function outputtexture(a) {
 if(a >= 0 && a < texturecount && a < initedcount) {
 // only output if tex had been initialized with a capture
 if(texset[a].name.indexOf("_cap") >= 0) {
 outlet(0, "jit_gl_texture", texset[a].name);
        }
    }
}

Oh, I didn't realize the count was not right... Thank you for noticing it.

I still have some issues / inconsistencies with the transparency in gl2 and errors in gl3 (jit.gl.texture: bind: GL Error: Invalid operation)

I did a clean install of Max but it doesn't change... :(

Did you try it with gl2 or gl3 ?

I also tried with gl3. But meanwhile I can reproduce the behaviour you mentioned. It seems like if you set drawto MAIN for the [js] that it works without problems.
