My active subtool no longer changes to a lighter color when selected. This is only on one particular model and I appear to have saved the model this way. Earlier versions of the same model change color as expected. The only difference that I know of between this model and the earlier version is I have posed this one with Transpose Master and the earlier version I have not. I have tried filling all the subtools with flat color and have tried different settings on the --> Preferences:Edit:inactive subtool dimming slider. What am I missing?
You just need to turn Tool>Polypaint>Colorize off for all the subtools. The quick way to do this is to Shift+click the paintbrush icon for the selected subtool in the list.
That was it.
Thanks for scraping some noob off of me.
