Hi guys. I´m working to finish my VSTi´s GUI and found something I can´t do. This is a preview of my GUI:

I want to have that "glassy" effect on a separate bmp and apply if on top of everything else, with some transparence. How do I achieve this? Of course, I want to be able to use the knobs and switches under that layer. Thanks.

Just make sure the alpha channel is transparent enough to see the controls through the window... it shouldn't stop mouse controls from getting through.

Unless your question is more about PhotoShop?

Make a fully transparent window in the middle of your opaque frame.

put your glassy effect in a layer below that and set it's transparency to an appropriate value < 100%

Export the image as PNG or GIF...

If you want to retain control of the transparency level within SynthMaker you could export a frame object with a fully transparent middle and an opaque glassy effect and set the Alpha blend of the glassy effect within SynthMaker.

Hi oddson, thanks for your answer. But it doesn´t work with my vst. Here´s an example of how thing are set up in my schematic, and you can see that your image doesn´t show on top of the rest of the gui.

Any ideas?

BTW, no, I wasn´t asking about photoshop. In fact, I´m using the GIMP for all this graphics - it works great, apart from the odd crash every 2 hours. 😕 🙂

OK. What you do is you create a new V input into the image module. Then connect from the GUI prim to the Image V input. Make sure this connection is the last one out from the GUI Prim. This way your image will be placed above everything else. Works perfectly.

    Open it in SynthMaker?

    It goes on the track you’re editing there, in place of that track’s sound, and into My sounds. Your other tracks stay as they are.

    Want to keep that track’s sound? Start a new song in SynthMaker first (Song › New song), then open this.
