Use black with channel as mask

Recommended Posts

I often get masks as black/white images from rendering or other tools. Is there a quick way to turn them into masks? Or use them as mask...

And another one: How can I invert a shape mask effect

Thanks. Didn’t seen 1. Before. 

Yes about 2 that is a needed feature. Sometimes I need to mask things inside and things outside. Using the same shape here is really helpful, especially if changes keep coming. That and instanced layers.

Did some tests on 'Rasterize to Mask' command and have to say, that stinks! 

Such a bad translation of a Alpha mask. Its nothing more then taking the black 100% color and make a stencil out of it. So every grey is ignored and the mask leaves a clear border on the edges.

I can't understand why you can paint with black and white in a mask, but that stupid mask is not considered like a black white image, like in other painting software. It looks like Affinity created a real problem for users here. 

So the work around is like before: select a color in the channel with the Select Sample Color and great a mask manual. Bad job guys..

Instead of using the "Rasterize to Mask" command, in the Layers panel, take the layer you want to use as a mask and drag it over the thumbnail of the layer you want it to be a mask of.  A vertical highlight should appear on the right edge of the thumbnail as you are dragging if you have the pointer over the correct place to drop it.

well dragging into onto a layer does only work, if its mask.

Meanwhile I got it to work, seem to be an issue with the color proof of the file. (32bit). Looks promising, will keep testing it so. 

Anyhow, why isn't that command directly under the layer popup menu? It was one of the hardest thing coming from Photoshop.
