As in "I can see other layers but my brush only blends with the colors of the active layer".

no

cant you make them invisible? i remember something about that.

I just thought of this- I remember reading that after submitting a finished piece you can't erase a layer(this is on DBA's lightening picture I think). Maybe after a piece is submitted as finished you could go back and blend the two layers. I have to add that I'm not a layer expert though. I mostly use one layer. I've gotten confused to what I was doing when there are more than one layer to keep up with.

Where's Zack when ya need him! :)

i think dire means, can you use the blend tool and not have it blend the strokes on the layer above or below the one you are working on while it is visible. and from my experience you cannot. you can make the layer not visible and it wont blend the strokes on that layer. unless someone knows something i dont. but yeah i wish that was something lascaux didnt do. or did do. or whatever.

the blend checkbox picks up color from all layers, if you don't want it to pick up color from a particular layer, you'll have to set it to invisible.

I guess it depends on what type of pic you're doing, but I have blended one layer and the other was left alone... but I think I had filled the entire layer with paint, so it totally covered the previous layer... and I was able to blend the 2nd... if'n ya know what the hell I'm tryin' to say...

Yes, I set them to invisible but it'd be more convenient to know exactly how it's going to look. It's not such a big deal, anyway. I'd rather have better anti-aliasing *"open mouth" emoticon here*

Just lay one color over another with each color being a layer and then adjust the opacity of the layer on top, then use the blend tool on the edge of the color on top so that it "bleeds" and looks like its blending into the layer underneath it.
