Paint unlimited "splats" on objects!




Now a youtube video on how to setup:
*Hint...just add "Paint Target" and a Material with the Paint Shader!

 

Approved on Asset store:
https://www.assetstore.unity3d.com/en/#!/content/102269

I'll make a post in the asset section soon.

 

Fantastic. Your price is way too low, man!

The first million-star reviews are hitting the asset store.

This is the way to make Splatoon -like scenes in Unity, and many more uses too.

 

THANKS....glad you like it


Just an FYI to everyone...
this has been tested with Unity 2018+
BUT...only works with built-in render..so can't use the custom pipelines yet.
I plan to add support sometime

 

@Fattie
Thanks for the review.

I made a simple test...
Plane is scaled 10 1 10

I then tried 25x, 100x....
can't seem to repro it not painting.

as for the stretching...try a higher texture value here:


remember, the bigger the object the paint needs more resolution
100x is just too big even for 4096x4096, 25x looks ok.

what version of unity, OS, and platform do you have selected?
My test was 2018.1.9f2, Windows 10, Windows Build

 

I tested a cube at 25,1,25 scale...
is this the "stretching"? if so just need to increase Texture size.

Left: Increased Right: Default 256

 

I was playing around and created an overlay version...
this means you can use custom shaders, or just a blank area.

check it out..paint on a glass shader, or invisible wall.

still have some work to do but i thought it was cool.

 

Scaling issue:

Here's a video:
https://www.dropbox.com/s/6tg84ium9a6j0qe/paintz-scale-plane.webm?dl=0

1. using Windows10 (highest nvidia etc)
2. absolutely latest Unity (18.2.6 presently)
3. create brand new totally empty project
4. import, from asset store, current PaintZ asset
5. click "Add .. 3D .. Plane"
6. add

PaintTarget

; choose

Material

7. put

PaintExample

quick test script on

Camera

Play and paint, using various scale on the Plane. it is only necessary to change the "x" scale.

Notice when you get above about 10, it behaves strangely. How to understand this?

 

Like I said, if you scale it up...you need to also increase the texture size.
see in your video you have it set to 256x256
you are trying to paint an object 10 times bigger, but with the same amount of "paint"

Try 1024x1024...
* or 2048x2048 or 4096x4096

 

That makes perfect sense - good one. I'm sure that will help a lot of readers.

Next question! I know how to paint on a surface, which, is textured using one of the supplied "Paint Materials" (white, orange, blue etc).



Say I have a floor surface which is a conventional texture (i.e., it's an image of a floor).



In fact, how do I paint on that? Can I create a "paintable texture", using, a PNG to begin with?

(your "invisible texture" idea mentioned above could work, but surely a "png based paintable" texture is the way to go, no?)

Thanks, PaintZ Pals!

 

"Say I have a floor surface which is a conventional texture"
just create a new Material
change shader type to PaintStandard
assign your textures like you would any Standard shader.

I can make a quick video if this is not clear.


"how many splats per second"

all splats are queued, then later blit to the texture.
this option is the one that effects performance.

checked it will paint all queued that frame.
unchecked it will paint 10 per frame until que is empty.


"Does it matter how many splats in total exist"
no, this is not a decal system.
once painted, it's just part of a texture that is always displayed.
0 splats, or 1 million...same performance

 

Floor: fantastic info, I'm sure it will help many users. It's totally clear.

Splats per second: AHHHHHH. Fantastic. Got it now. In fact I am limiting splats per frame to 2 or 3, so, fantastic.

Undecal: AHHHHHHHHH. Totally fantastic. That is magic: got it now. Magnificent!

{Thought: when you build a, say, racetrack (let's say 10km long), you always chop it in to sections (perhaps 100m each) so that it can occlude as the viewpoint spins around. (If you dynamically build a racetrack or similar, this is an important task - to dynamically chop it up for occlusion.) In fact, is this issue relevant to Splatz? Does it occlude, does it need to, or is it a non-issue?}

 

It's just a shader, so it has nothing to do with occlusion or anything else.

Tips:
Use as small "Paint Texture" for each object that looks good to you.

Don't put it on small objects, then spread them around (like rocks)
Each object will create a new Texture, possible to run out of GPU memory.

"Setup On Startup" will create the texture even if you haven't painted that object yet.
suggest keeping this unchecked, so it will create the textures only when it gets painted the first time.

 

What about drawing on Terrain?



(that's an attempt using a dynamic decals library, which is hopeless unfortunately)

Terrain shaders are very specific - I wonder if it's possible??

 

Submitted V1.5 to asset store

Added New Shaders and API to raycast colors/channels

 

Hi i sent you an email about splat rect issue.

 

Got it and replied
*keep in mind timezones for reply time, it was 3AM my time when you sent the message.

 

Hey man, great asset. Interested to get but a few questions:

Any idea when the new rp support might be ready?

Also, is it possible to detect if a game object touched the exact paint color type?

 

say @Rumbleboxer , what did you mean by "rp" rp support?

Thanks! Yes, it's a fantastic asset.

 

@Rumbleboxer
I don't plan to support SRP until it comes out of preview.
*Unless I can convert the shaders to Amplify shaders

It has a special raycast function that will return the color


@Fattie
rp = Scriptable Rendering Pipeline


@everyone
I'm currently out of town for the holidays, limited support
*will be back Jan 5, 2019

 

I had a few customer support requests on how the score system worked.

so I'll post this example that displays as % (includes code, prefab etc)




I'll include this in the next update now that 2019.1 has been released to support LWRP
*keep in mind LWRP will require an almost complete recode, so no ETA!
*right now this asset is ONLY built-in render compatible

 

Hello, my name is Julian and I am very interested in buying Paintz, but I wanted to make sure that your asset could do what I am hoping it could do before I buy.
In a nutshell, I am hoping to use this asset to create a trail of paint that follows a paintbrush, in the same way that a paintbrush would leave a trail of paint in real life. I would want it to leave a trail of paint on a relatively low-poly surface. Can you attach this asset to an object so that wherever it goes, it leaves a trail of paint, or is is more geared towards creating "paint projectiles"?

Thank you so much for your time and response!

Best Regards,

-Julian

 

*I replied to your email, but I will post it here also.



Check the demo, and click "Trails".

http://bocs.site/demo/paintz1/






"I would want it to leave a trail of paint on a relatively low-poly surface."

This is texture based, so it doesn't care if the model is 10 polys or 10 million polys.
You set a texture resolution per object that can be painted.

*Keep in mind it's limited to 4 colors per object.

Can you please explain how I can get the Pain Only Double-Sided on an invisible object? I don't have your asset yet, but in your video, I can see painting on an invisible wall, but only single-sided. That's the only feature I need and I will buy this asset if it can do that.

 

@ben-rasooli

in the video I just used PaintOnly...if I would have used PaintOnlyDoubleSided it would be what you want.

take a look at the sample scene from another angle which does use it:


very simple to use, just change the material shader of the object you want painted.

 

Solved my problem, it was a shader inclusion problem.

Thank you for this great asset!

 

If I need more colors, how to do?

 

I get asked this alot....

paint is stored as an 8-bit signed distance field in the Red, Green, Blue, and Alpha channels, so 1 channel per color.
4 colors is a hard limit, all code and shaders would have to be redone.

 

Hi. Your asset is amazing. Thanks for your job!
But I have a question. Is there any possibility to highlighe last splat? I mean the situation when I`m drawing on already painted territory with the same color. I can`t see the result of painting at this situation. Is it possible to make a normal texture for every painted spalt?
And also when I set a normal texture for splats then clearPaint via the code, the normal texture doesn`t work anymore. Thanks for help)

 

I don't think "highlighting" the last splat how you explain will be possible, they are just painted and normal maps are not changed.

I'll look into "I set a normal texture for splats then clearPaint via the code, the normal texture doesn`t work anymore".

 

Thanks a lot)

 

@Wtmln
If your still having issues, contact me via PM or email...not able to repro

Submitted Version 1.6.1 to store
Requested shader variations (Transparent) and some bug fixes, optimizations.

 

Any interest with an Obi Fluid integration?

 

Wow Nice ! Two question: Does it work on LWRP ? And how's the performance on mobile ?

 

LWRP - Not yet, but definitely something planned. (no time frame)

Moblie - Runs great, shader is just alittle slower then the standard moblie.

 

Thanks for the info! I work more on mobile and in that case, I'll definitely add it to my whishlist. I might buy it when I start polishing my game.

 

Would be interested in an integration tutorial for Invector 3PS. Probably easy to figure out but I’m sure it would help others also.

 

I don't have that asset, but I'll try to include a prefab in the next update that can be attached to the muzzle and shoot paint.

 

Absolutely love the look of this! Was wondering if you had any update on SRP support?

 

I'm currenly furloughed for a month due to the current situtation, so I now have the time to devote to research updating to SRP/URP. I can't promise it will be supported, but I should know either way this month.

 

I'll definitely be picking this up if you get URP working

 

This looks very nice indeed, several applications I can think of, is there a tutorial available, or an option to enable?

 

Next update I hope to include Obi support, URP, and some bug fixes....lots of things I've worked on but haven't polished enough to include.

 

That's great! Thanks for the update. Do you think the update will be available before the end of the month?

 

I don't know when, but I've had some sucess with making a compatible ShaderGraph shader, still needs some features....

 

Look great! I don't mean to rush you. Keep up the great work

 

I've complely converted the shaders to Shader Graph, and Included some variations as examples.
Sending out to some testers now, but I'm happy with the results so far.

Just need to do some clean up, but can finally say URP will be added in the next release. (let's say 1 week to fix any issues, and then it's upto the asset store to approve)

Quick video showing all features are working...

 

Things worked out faster then expected, Next update is finished!
