New brush without color #24

Open ghost opened 7 years ago

ghost commented 7 years ago

Hi,

It's possible to create a new texture without color? This is, keep the texture colours, I want to create a glitter pen, and keep the texture colours....

any updates?

it'd take quite some modifications to do this. offhand i'm not sure exactly how it'd need to be done - i think it might need a new shader and a new brush class, at minimum. there's no built-in way to do this with the current brush system.
