It seems like the texture that jit.grab outputs is unable to correctly alpha blend like other textures. Here's a simple patch to show. I also tried feeding the texture in jit.gl.node, same results. I'm using max 7.2.2 32bit Windows 10 w/ VIDDL 1.0.0.

Hi!
It seems like the texture that jit.grab outputs is unable to correctly alpha blend like other textures. Here's a simple patch to show. I also tried feeding the texture in jit.gl.node, same results.  I'm using max 7.2.2 32bit Windows 10 w/ VIDDL 1.0.0.
Any help would be appreciated!


jit-grab-output_texture-1-doesnt-blend

seems to work fine. can you describe what you're seeing that's unexpected and give steps to repro?

In the patch, after setting the jit.movie @output_texture 1 to blend_enable 1, we can change the alpha and accordingly, the image fades in and out. That's perfect.

Whereas with jit.grab @output_texture 1, when we I set it to blend_enable 1, the image instantly dissapears whatever the alpha is set to.

Neither your patch or mine works on my setup. I just either get image or not, no blending. I'm guessing you guys are testing on Mac and this is a Windows issue. Anybody on Windows can verify?

Tested on 2 different PCs same result. Also sent a report to Cycling a while ago, no acknowledgement yet.

Bump!

Thanks for looking into it!


sorry for the delay. yes i can reproduce something strange going on here on windows with jit.grab and output_texture.

hi hugobox.

we'll take a look.


workaround is to force a proper alpha channel using jit.gl.pix:

Thanks Rob! Was looking into ways of forcing an alpha, your solution is much cleaner than my current workaround! Really appreciated!

Jit.Grab @output_texture 1 doesn't blend
