Hi! If you are on windows, OurPaint supports Windows Ink, and I think all tablets on windows now have that driver option (after you installed the driver, you can set that in the program), and you will have no problem using it. I have Huion/xppen users saying they work fine, even without windows ink, those tablets mostly uses wacom-compatible driver, so programs can recognize them just fine. On linux, it should also just work after driver installation. You can pick any reasonably reputable model and you should be good to go :D

If you ever encounter any problems with tables, please report back to me and I’ll cooperate with you to fix the issue. (most of the time just minor tweaks and we can support a brand new tablet)

Cheers!

Good to know about Windows Ink, that is super convenient! I have ordered an entry level HUION, got a good deal (almost half off!), I will let you know about compatibility once it arrives, but after what you said I think it will be just fine. Thank you for your help!

Also I might as well add here, it is phenomenal that you are both artistically skilled and in possession of software finesse! Mighty good work!

Just got my tablet, excited to work with OurPaint! It seems to work very smoothly, but there is no pressure sensitivity? Perhaps it is an unsupported feature, or I am not setting it up the device correctly. When I try different brushes, I am not getting any difference in stroke thickness/intensity when I let off or push with more pressure. Also, Windows tells me that the table is online, but has a "driver error"... I downloaded from huion.com/download and it seems to have worked, gave me a program for remapping hotkeys and such, and restarted my computer, but nada. Your manual says to choose from Windows Ink or WinTab to get pressure event, but also that if it doesn't work, my input just isn't supported yet. You mentioned earlier that you know people use OurPaint with Huions, do they say anything about this? Anyways, you're not tech support, but I would appreciate any insight you may have. Cheers!

Hi hi! You may want to toggle this setting in windows: In windows pen setting, you can find a “allow this device to be used as mouse” option (You may need to dig a little bit, it’s in the setting app in Win11 and Win10, can’t remember that clear…), you either set this option to on and off, and together with the wintab option in OurPaint and Huion software, you should get pressure to appear in one combination… Use “Digital Pointy” brush to see the pressure effect more prominently. I had to use this option as well to get pressure on windows, it’s kinda weird.

Also, see if any other programs recognize pressure, like Krita or Blender.

Using "Digital Pointy" brush, I got pressure sensitivity to work with "WinTab" driver in OurPaint, and "Let me use my pen as a mouse when it's available" set to ON in Windows Pen settings (Windows 11)! I didn't realize the default "OurPaint" didn't really show pressure sensitivity, is this part of the "programmable, featureless, node-based" brush concept? If so I shall have to dig into this deeply and see how to make brushes that show the pressure sensitivity by default and change all your nice preset brushes! Thank you for your help!

Unfortunately the program keeps crashing if I switch brushes and try to draw much more than a few strokes.

Also, I opened Blender 3.0.0, and if you are curious, it seemed to work just fine, and I was able to adjust pressure sensitivity with the download program from Huion. It worked whether mouse pen option was on or off in Windows Pen settings.

Hi! If this option works, then pressure is working normally. Most brushes in OurPaint has pressure dynamics already. If you want a simple configuration, just add a new brush, don’t enable the nodes, then there will be a P symbol next to size/transparency sliders and if you click that it will automatically use pressure for those properties. However the crashing thing may need more investigation. It shouldn’t crash that frequently as I barely had any using this to create my comics… I’m actually not sure how can I reproduce the crash… Could you describe what your exact actions are when you encounter the crash? Thanks!!

Hi, been busy lately, didn't mean to drop this suddenly. I just did a fresh install of the program, launched via itch.io Windows client, clicked digital pointy brush twice (once to remove splash screen, once to actually select brush), go on to canvas to draw, and as soon as I try to touch my pen down to the tablet, OurPaint becomes unresponsive. The pen and tablet work fine with other programs I've tried, not sure what to do here...

EDIT: I can use the regular default "Our Brush" fine, it seems to be something about Digital Pointy. Pencil Thicker brush works for about half a second before program is unresponsive, but Smudgy works, so it is probably related to pressure sensitivity.

EDIT 2: For some reason, it has stopped crashing when using Digital Pointy and other pressure sensitive brushes... I do not know what changed. But while it's not crashing, I tested the options to see what worked for pressure sensitivity. Maybe you want to copy this for description of the program, so others can know more easily, these comments are making a long, deep thread ^^;

Here is this table of what settings work for Digital Pointy (pressure sensitive brush), with OurPaint driver setting on left, Windows Pen mouse settings on right. I restarted OurPaint before each change to confirm fresh session:

Wacom Device: WinTab	Windows Pen: ON -> "Let me use my pen as a mouse when it's available"	Pressure sensitivity result: SUCCESSFUL
Wacom Device: WinTab	Windows Pen: OFF -> "Let me use my pen as a mouse when it's available"	Pressure sensitivity result: SUCCESSFUL
Wacom Device: Windows Ink	Windows Pen: ON -> "Let me use my pen as a mouse when it's available"	Pressure sensitivity result: FAILURE
Wacom Device: Windows Ink	Windows Pen: OFF -> "Let me use my pen as a mouse when it's available"	Pressure sensitivity result: FAILURE

So I have to use WinTab for it to work, but once I do, either ON or OFF for Windows Pen mouse option doesn't affect result of OurPaint for whatever reason.

HOWEVER now I have a new issue... for whatever reason there is some lagging when I do many repeated strokes, or long but fast strokes.

EDIT 3: it appears that it is either crashing or lagging when using ANY brush, REGARDLESS of Windows Pen mouse setting being on or off. If I make many long fast repeated strokes, I can make the program crash, or at least go unresponsive for a good long while. This program is promising but still remains a mystery to me...

Apologies for text wall, I hope this is helpful information for debugging!

Hi hi! Thanks for your detailed feedback! I will definitely check on windows and try to debug this issue. There might be some slight memory-related bugs that due to the difference of how OurPaint allocates on windows and linux it might not work as well. I will try to fix this in the next update.

Thank you so much again for getting back :D

Of course! Also I just found your repository, with the comfortable theme of OurPaint <3 , I will post more issues and such I find there if you don't mind, don't want to clog your comments thread here on itch, there is better organization there anyway. Cheers!
