Sorry if this topic has been made somewhere, but the ones i find does not help in a single bit.
I've just started using this software so i don't know much. I'm trying to making a brush to start from thick and goes thinner after ending the brush. I'm not using a Tablet but rather a laptop with a mouse. I'm not sure if you can do this function with a mouse. If there is so, may I know the steps for it.

Use "Fade" sensor and reverse curve, play with distance. It will work with mouse (I recommend to not draw with mouse though).

Thanks for the tip, it worked just like what i wanted. Just a few tweaks to make it perfect.
