I came to post this question/request. Would it be possible to implement channel support for blend radius the way you have for radius? I would really love to be able to control the blend radius using a PRT channel.
I’d guess this could make things quite slow for the mesher 
Is that a gut feeling or based on coding knowledge?
If you can set the radius per particle, it seems to me that setting the blend value per particle wouldn’t be a massive overhead. But I could be wrong.
This has been logged as a wish. My gut says it might be doable, but we will see. 
Thanks Bobo!
