Affinity Photo Paint Mixer Brush stops painting

[kat]

Affinity Photo Paint Mixer Brush stops painting regularly.

I've watched the youtube tutorials &  this never happens. I use a wacom 6 with n, c & l set.

This file is 6324 px x 5200px. Is there a file size limit problem?

unless I have auto load clicked Paint Mixer Brush doesn't do anything. Help please

Hi @kat,

Auto Load Brush/Load Brush will load Colour 1 set within the colour panel each time you attempt to paint onto your canvas, I don't believe your file size will cause the issue.

Could you try Unticking Auto Load Brush > Clean Brush > Try painting onto your currently selected layer

Really appreciate your taking the time to respond.

Turning Auto Load Brush OFF & clicking Clean Brush "C". Should be able to drag thru paint, but can't.

In the past I could get PMB to work for awhile then it would stop. This has been happening for years.

I tried PMB in a tiny file — doesn't work. Can't find a "protecting pixels" in a brush or on layers that might be checked on & off.

So for now I can only use regular brushes.

Hi @kat,

Do you have a sample file/video demonstrating the issue on your side? By default if a layer isn't selected assistant will create a new pixel layer which it won't mix on since there is no content however I doubt this is the issue you're experiencing.

Thanks for hanging in there, Nathan
