[DEPRECATED] Terrain Pressure Paint - Paint terrain with your pressure sensitive stylus inside Unity

Terrain Pressure Paint is an editor extension that allows painting on terrain with a pressure sensitive input device, like a Wacom tablet and pen.

It allows you to use pressure control for:

• Raise/Lower - Brush Size and Opacity
• Paint Height - Brush Size and Opacity
• Smooth Height - Brush Size and Opacity
• Paint Texture - Brush Size, Opacity and Target Strength
• Paint Details - Brush Size, Opacity and Target Strength
• Place Trees - Brush Size and Tree Density

You can easily select which variables to control with pen pressure, and adjust minimum and maximum values.

Get it on the asset store now: http://u3d.as/bK7

 

Just got this tonight. Really digging it so far. Takes a few minutes to get used to, but it doesn't step on the toes of the existing terrain tools and complements them. Great job!

 

Will this work with the pressure sensitive pen on the Surface Pro 4 ?

 

I'm afraid I don't have a Surface Pro to test with, but I believe it should work as long as you have installed the optional wintab drivers for it, as the plugin uses the wintab interface.

If you want to test it out, and it turns out it doesn't work, just send me a PM with the order number and I will arrange for a refund.

 

Hi, the README link on the asset store page seems to be broken. Does this plugin work on OSX?

Also, it looks like source is included, do you think this could be adapted to work at runtime?

 

Yeah sorry about that, I hope to have it back up in a few days.

Yes it works on OSX.

It probably could, but only on Windows. The reason is that on OSX it gets the pressure from the Unity editor, while on Windows it uses the WinTab interface.

EDIT: It's possible to do the same at runtime on OSX of course, through a native plugin. If this is something you need, I have some sources with a small test case for it that you can have a look at. It's really rudimentary though, so no warranties.

 

Thanks for the info! I just bought your plugin and it works great on OSX. Painting terrain with pressure feels great.

It looks like Event.current.pressure works in OnGUI at runtime too, as long at the EventType is MouseDrag.

Do you know if Wacom tilt values are available too?

 

Thanks for the purchase! Tilt values are not available in Unity, you'd definitely need a native plugin for that.

 

Can you do an update for the latest unity version? thanks

 

I'm working on an update for 5.6, I'll have it available shortly.

 

Great thanks for the heads up!

 

The update for Unity 5.6 is now live on the asset store.

It also includes a new feature to control height of placed trees with pen pressure.

 

Hi, I got some issues.

1. Pressure slider doesn't work, even with tablet off.
2. Toggle "Size" doesn't save its value.
3. Sliders Opacity & Target Strength in terrain settings falls to zero every time I select texture to paint, so no painting in result.

What can I do, help please?

 

Hi, can you tell me which OS, Unity version and tablet you are using?

 

I have Windows 8.1, Unity 5.6.3.p2 and tablet Genius EasyPen i405X

 

Can't get this to work at all When I open the window it either hard freezes Unity or crashes it.

Windows 7 Enterprise SP 1
Unity 2017.2
Wacom Intuos 5 Touch (though there are a few different versions of Wacoms here I could possibly test with if needed)

Any thoughts?

 

Some debugging it looks like it has to do with the closing of the context in OnEnable. If I comment that out it doesn't hang.
EDIT: Actually any call to CloseContext causes the hang, whether it is in OnEnable or OnDisable or OnDestroy, any of those calls to CloseContext causes the editor to hang. Same if it gets called as part of the assembly reload process.

Appears to be hanging waiting on a response from WinTab. If I unplug the tablet it will error our/timeout an unfreeze.

 

Further debugging leads me to the Application.Exit() call in MessageEvents.Close()

If I comment that out everything works fine within normal use, opening/closing the window, painting, etc. However Unity will lock up when A) Exiting, or B) Reloading assemblies

 

Do you have the latest drivers for the tablet installed?

It sounds like it doesn't fire any events through the WinTAB interface that this plugin uses, which most likely means that the tablet is not supported I'm afraid, and I don't have a Genius tablet to test with myself.

Try updating your drivers, or see if you can find something like the "optional WinTAB drivers" that exists for the Surface Pro, mentioned earlier in this thread.

If you can't get it working with your tablet, feel free to request a refund and I'll be happy to accommodate.

This is because there are no pressure events received, and the pressure is set to zero by default. I'll release an update to fix this, but it won't help your situation as no pressure events are registered using your tablet.

 

Would you be happening to use the new .NET 4.6 runtime in your project? If so, do you see the same issue when using 3.5?

 

We would be yes, and I think we have to but I will try to test it out with 3.5 on Monday and see if that changes anything.

 

I don't want to refund, I want to paint terrain with pressure pen My tablet works well with pressure in GIMP or Krita, but I'll try to update drivers anyway.

 

I recommend to change the tablet for a wacom, that will fix your issue.

 

After reinstalling drivers, my tablet paints a terrain like an ordinary mouse - with size, target strength and opacity. But pressure is out only.

 

I'm fairly certain this is the issue. For now what you can do is delete the following files:

• Assets/Plugins/FreakshowStudio/TerrainPressurePaint/Editor/Plugins/System.Drawing.dll
• Assets/Plugins/FreakshowStudio/TerrainPressurePaint/Editor/Plugins/System.Windows.Forms.dll

Then put the attached mcs.rsp file from this post in your Assets/ folder.

The reason for this is that the included files are compiled for .NET 2.0 and won't work with 4.6, you would need the same files for 4.6 to work.

Using the rsp file instead, you should get the correct assemblies for the runtime version you are using, but note that this will not work for .NET 2.0 subset, as that profile doesn't include the necessary assemblies.

You could also copy over the .dll files for 4.6 from Editor/Data/MonoBleedingEdge/lib/mono/4.5 to replace the included ones.

I'll try to fix this in an update as well, but I have to ponder the best way to do it. mcs.rsp is a file potentially used by the whole project, so I'm not sure it makes sense to include it with the asset, and it also affects player build.

 

Yes this is consistent with no pressure events being received, I'm afraid your tablet is not supported then.

 

Ah yes that makes sense. I got so tied up in the specifics that I didn't stop to consider that.

Given that they are just system DLLs, shouldn't I be able to just replace them with standard versions from 4.6? Never ran into .RSP files so I admit to not knowing what that is, but I'll do some research.

 

Yes you could just replace them with the ones included with Unity, they should be in the folder Editor/Data/MonoBleedingEdge/lib/mono/4.5

mcs.rsp is a response file for the compiler (mcs). It's basically just extra command line parameters for the compiler. The one I posted includes the flags -r:System.Drawing and -r:System.Windows.Forms which tells the compiler to reference these when building.

Using response files is the recommended approach going forward, as it will handle both (and possible future) runtimes. It is a bit inflexible though, as you can only have one per project as far as I can tell.

 

How it can be? My tablet draws with pressure in any other software.

 

So deleting the included DLLs and adding the .rsp file doesn't seem to fix it. No errors in Unity (which implies it is loading the assemblies), but the same behaviour of completely freezing the editor when trying to open the window.

I then tried copying over the DLLs specifically from both MonoBleedingEdge 4.5 and 4.6-api and in both cases for some reason Unity just gives an error saying it couldn't load them.

 

After refactoring our code to work in the older Mono 2.0 environment I see the proper behaviour. Not sure why I can't get it working in 4.6 though

 

The other software probably relies on system messages to get at the pressure, while this plugin just uses the WinTAB interface. Most, but not all, tablets will be WinTAB compatible.

Have you tried using the plugin in an empty project?

 

After adding the RSP file, could you try to make sure the code is re-compiled? Just add a new blank line in TerrainPressurePaint.cs or something?

I'd also advice that you try in an empty project first, just to be absolutely sure there isn't anything else in your project interfering with it.

With the RSP file it works fine for me here on 4.6.

You can also just keep the offending lines commented out, you'll be leaking processes every time you close the Terrain Pressure Paint window, but they should be closed when you exit Unity.

 

Yep, with the same result.

 

Ok, then I'm sorry but I don't have access to a Genius tablet to test for myself, so I can only assume that it is not compatible.

 

I've still been unable to get this working with 4.6

I started a blank empty project in Unity 2017.3f3 today, then imported the mcs.rsp file. I then imported TerrainPressurePaint (and unchecked the two DLLs so they did not import).

Then into Window->Terrain Pressure Paint and it immediately freezes the editor.

The project was completely blank except for that.

 

Does this only work with the native Unity terrain tools or is this also compatible with other brush-based terrain editing tools available in the Asset Store such as Terrain Former and/or Terra Brush?

 

It only works with the native Unity terrain tools I'm afraid.

 

Ok, thanks for the reply!

 

Now I got a Wacom tablet and a Linne crater becomes real )

 

I had some trouble to get it to work in the latest unity 2018.3b on the mac, the wacom did not have pressure. can anyone test if it works for you?

 

I'm sorry to say that this asset has now been deprecated. The changes to the terrain system in 2018.3, coupled with the update of .NET, makes the update to big to justify for the low number of sales I'm having.

I've submitted an update making the asset free, for anyone who wants to use it with an older version of Unity, but it will not receive any further updates. You can still edit your terrains in an older version and then bring them into the new version if you don't mind the extra steps.

If you have purchased the asset recently and feel let down that it's now free, please feel free to request a refund.

Sorry about that @Lars-Steenhoff and everybody else.

 

Can you, if you know, tell me what steps I need to do to make it run on the Mac? in 2018.3 , because I thought that pressure was supported native on Mac without the need for dll's

 

Yes the pressure should be supported, I'm not sure if Unity has changed anything in that regard though. Do you get anything in the blue sensitivity bar in the plugin? If that one registers the pressure then it is detected as it should.

If you get pressure info, it's only a matter of feeding this to Unity. What the plugin does is change some values in the terrain inspector, and some in the terrainData struct if I remember correctly. You would have to change this to match the new terrain inspector, you can find the fields you need to change either by looking at the sources, if 2018.3 is available yet and they have the source for the terrain inspector there, or as I did by decompiling the UnityEditor assembly.

 

Sorry I was mistaken, in 2018.3 on my Mac it all works just fine. I can paint with pressure on the new terrain!

 

Please keep the tool for sale and don't deprecate it for Mac users at least

 

Oh okay, that's good then. It'll still be available, only with a notice that it's not maintained and with a price of zero.

 

Thanks, just I would change the wording Depricated to something like No longer maintained , normally on the asset store Depricated means it no longer available.

 

Can I ask one thing even now that you don't have time to support it....
Please have look at the latest unity alpha, do you know how I can fix this error?
