Replicating a photoshop brush behaviour in Affinity Photo

[1k0]

Hello there!

I'd like to migrate from Photoshop for digital paint and the only thing that is missing is the Tonko House brush pack that I can import in Affinity photo but can't get it to work the same way it works in Photoshop.
I'm pretty sure it's an easy fix to adjust in the brush setting or create a new one from my reference brush stroke.

Let's explain what I'm looking for:
- The brush has a texture in the background and for its shape (that is the easy part)
- When we press more on the stylus to fill more the stroke, the texture is replaced by a more dense brush stroke, but it keep the texture for the shape of the brush.

I passed a few hours on Affinity photo trying to replicate this behaviour, adjusting all settings but I'm not really close to get the same result, maybe some of you are expert at designing brushes and may light up my vision on how to proceed?

The 2 other brushes have the same process in mind, so if one is fixed, the other will be easy to adjust.

And if someone has already converted the Tonko house brush pack to Affinity Photo, I'll be really happy if you can share them!

Look at the attached image to better see what I mean.

Best regards

Accumulation maybe the way to go.

Set it to depend on pressure.

Thanks for you help,
However, it won't work, I already played with Accumulation Jitter and pressure, it just shows more and more the grunge texture instead of filling the stroke.
I also tried different Texture settings, nozzle, final, etc.
Then I started to play with Sub Brushes as it looks it's the process I'm looking for as in Photoshop, the filling effect of the brush come from a secondary brush in colour burn bend mode, but it doesn't seem to work the same way in Affinity Photo.
I'm pretty sure it's a game of finding the right mixture of these settings but I'm kind of lost ^^
