Not sure what you are saying here
Are you saying that the Paint Roller and Custom Brush* won’t paint at all?
Or that when the cursor is in Tool Mode you do not get, for example, the graphic representation of an actual paint roller as the cursor?
If the latter, then at least on Macs, there are no graphic cursor icons for the Paint Roller or Custom Brush in ARV, nor were there in previous versions of AR.
*With regard to the Custom Brush specifically, I have found that on starting ARV, and in past versions of AR as well, that the Custom Brush 90% of the time will not paint until a preset is first selected.
It seems to be the only tool that dose this but as I say I can’t reproduce this behaviour 100% of the time.
