All of my custom brushes from TVP11 appear extremely pixelated on TVP12

[swiftsketcher]

I can't figure out why this is happening. These brushes looked and worked perfectly fine before on TVP 11 but are completely unusable now. All aliasing settings are the same as before, here is what is looks like, along with other parameters:

Can you post your brushes? I'll check it out.

the only visible difference between the custom brush tool panels in the 2 versions is that the v12 version (light grey here) has integrated active line smoothing.
and a 'revert'option.

does it make a difference if you uncheck Activate line smoothing?

The screenshot shows a size of 7% (and AAliasing is blank?!) and I'm experiencing same things with the new algorithm while scaling down, it can make this kind of result depending how is the design of the brush.

I tried out the TVPaint 12 demo and noticed this behaviour also (as well as general instability, jagged lines remaining and frequent crashes). All of the anti-aliasing of my previous brushes weren't behaving the same as in tvpaint 11, extremely pixelated and completely breaking any thinner lined brushes.

Sorry, have been caught up with work.

Bumping this to revisit the issue, updated to TVP12.1.0 as well. Does anyone on the dev team have any solutions? At the end of my rope here and it's affecting my professional work that now looks inconsistent when editing older drawings from before TVP12.

An example of how the line used to look, then vs now:

(make sure to click, the thumbnail contains jagged lines not present in the full quality version, which also has jagged lines but this is due to being zoomed in)

I've tried checking and unchecking all new, old, best smoothing, max to no anti-aliasing, the results are the same. I've even attempted to recreate it in TVP12 with the exact stamp, and the results remain pixelated. Frustrating.

Can you post your brushes? I'll check it out.

Please let me know if you have issues or not! If you don't have any issues, would you mind posting your project and brush settings to see if I can replicate it?

Hello, I responded to your email.
The dev team is aware of this issue and are working on smoothing out the transition of brushes between v11 and v12.
This seems to be due to antialiasing settings being interpreted inconsistently by v12.

Thank you for looking into this! Appreciate the help from my email too, it's an immense relief.

I was able to fix the pixelation issue by checking the projection box in the custom brush settings.

Hello everyone,

We have been investigating the matter. This discrepancy between the look of your brushes in V11 and in V12 is caused by the rewriting of the antialiasing algorithms in TVPaint 12, like we intially thought.

The previous V11 antialiasing filters were imperfect and not implemented properly. Thus, they would blur things a lot, resulting in smoother but blurrier brush tips when applied to Custom Brushes. As a consequence, the edges of a Custom Brush stroke appear to be smoother (but blurrier) in TVPaint 11 than they should, had the antialiasing filters been more effective in the first place.

You have two options, should you need to retrieve the V11 looks in V12:

• You can recreate old brushes and rework their brush tips, so they look blurrier from the get-go (but this is a tedious process).

• You can degrade the quality of your brush tip in TVPaint 12 so that it looks blurrier:

-Select the Custom Brush you want to change the look of
-Click on the "Edit" button right next to the brush tip preview
-Divide the brush tip size by a half (vertically and horizontally) as much as necessary
-Put the antialiasing to "Medium" here:

-Compensate the size reduction by increasing the size parameter so the brush has the same size than before (resizing the brush this way will degrade its quality)
Here is the difference between an altered Custom Brush (left) and the non-altered version (right) in V12 after doing this (you can degrade the quality further if you want):

This may still not look as blurry / smooth than in TVPaint 11, however you can see that the stroke edges are a lot smoother after modifying the brush this way and closer in look to TVPaint 11:

You may also tweak other parameters to proceed. Some users reported tweaking their brushes Opacity Mapping setting to get even closer (or you can add some Projection, as it will fatten and blur the brush edges a litte bit, as you can see in fayala28's post above).

We hope this helps!

Thank you for the info Matthieu! I've had some success with those notes, others look like they will need to be remade, a small price for the new algorithm. In the end I imagine the less blurry look with brushes will be a good thing.

Also, not to highjack the thread, but as it relates to remaking brushes, is there any word on the brush BINs as mentioned in this thread? It was incredibly useful for brush creation and saving/tweaking versions quickly and easily(among other uses) and I miss it a lot!

Sorry for the delayed reply: I have updated the topic above. We have been discussing the deletion of the Bin with the team and are considering putting it back in a future update.
