Community asset pack

Megalomaniak

Are there any fellow godot users in here who might be interested in
collaborating on developing a general purpose asset pack for godot?

What
I mean by this is a whole pack of scripts, shaders - both shaderGraphs
and coded, and generic models i.e. the sort of things likely to be
useful for everyone.
Might as well in future expand to include
different scenes for different player controller models, be they first
person, third person, driving, flying. etc.

Don't know if any of
you are interested in collaborating but I'm inclined to do this
any-way's so might as well show what I'm currently working on.
Personally
I'm currently working on a water shader purely out of my own practical
interest but I recon that this will be of interest to at least some of
you as well.
<div class="post-text-align-center">Looks way better if you actually see the movement of the wave/ripples.</div>
At
this point the greatest challenge is getting renderTargets for both
planar reflection(easier) and refraction(harder - need to render it
without the water object visible)

2024 edit for those looking for the latest version of the water shadergraph, it's in post nr. 31

but also worth noting it was for godot 2 I think.

I'd like to BuuuuutI only do 2D stuff and pixel art :l So im not much use for this XD Unless you wanna make some 2D asset packs

Megalomaniak

I don't see why it has to be 3D only. I will likely be primarily contributing 3D related assets, but 2D textures are inevitably still going to be 2D textures, for an example.

When will be the time I create something :), some assets ::)

I have a few gradient shaders and outlines, but they're mostly for 2D. No idea if they work in 3D at all.

Megalomaniak

Hmm-progress, maybe? Tone-mapping's exposure was left low, though.
edit: better and bigger image.

Post 'em & we'll test 'em. ;D

Release early, release often the mantra says...

So be it then, that I shall include the WIP version with this post. I haven't tested it in other lighting situations yet(just 1 directional and one animated point light), however so YMMV, as they say. :-[

Heh, it was way more insane earlier, but I cleaned it up a 'little'

Oh, yeah, and here's the normal map:

Consider the whole shader MIT licensed.

Wow this looks great.I'm impressed what is possible with shaders also if people always complain about the improvable 3D rendering of Godot.

Oh, there always a lot to 'criticize' so long as it's constructive, but pointless complaint's are just a waste of everyone's time. So don't expect much from me on that note too soon, I'm still figuring this engine out. 8)

Would love to know when(if) you test the shader out. I'm sure there's a lot to be fixed and a lot of issues I haven't even run into yet, so any feed back from others would be great!

version 0.5!
changes since previous:

[li]moved uv scrolling to vertex program[/li]
[li]fixed water refraction:
[/li]
[li]added vertex displacement[/li]

For vertex animation I added an alpha channel to the bump map.
Updated version:

Just want to say: This looks amazing! :)

Looks cool. I like that you implemented a vertex shader.But i think the coloring was better in your last post (there it looked more realistic. Now it is to clean, transparent, blue)I try to get it to work but I'm messing anything up with the uv coords. I just imported a subdivided mesh (for the vertex shader) and added your shader with the texture you posted. But i only get a moving plane :(I will countinue trying and tell you if i found my mistake. But I would appreciate if you have got a tip.

Post for me a screenshot of the shader parameters and lets see if we can figure it out. 🙂

As for quick tips, try tweaking the displacement factor value?

Here is the picure with my shader settings and how it looks.I only have some lines which are moving. So it seems something is wrong with the normal map or my uv map...[url=http://postimage.org/][img width=220 height=107]http://s16.postimg.org/hhv74n52t/shader_Params.jpg[/img][/url]

Right the UV input is a multiplier. put 1 into uv and 2 into detail for starters. They should be named uv multiplier and detail multiplier, and I'd input 'integers' i.e.1, 2 ,3.
I forgot to rename them after rebuilding the uv/scroller network in the vertex program, in other words totally my mistake. :-X

Also, stick a large textured surface underneath it, because I'm not using transparency in there - its a screensample that is warped by the normalmap for the refraction.

And the reflection target is supposed to be empty, I put it in so that reflection could be rendered from a companion camera/secondary viewport for planar reflection. It's multiplied over the specular reflection.

edit: oh, and:

😉

I now finally get okay results but only If I set speed to: 0.Otherwise there are again only some lines like in the screenshot I posted before.It seems like my the texture isn't repeating so that when the shader moves the UV map for animation It moves the to the area where there is no texture anymore.

toger5

Okay found out what the problem was:you need to make the texture repeating manually. (in the Inspector in the texture settings.)Thought that would be default.So now It works (really good)How can I make the settings so that it looks more like the version 0.3 where the water didn't seemed so clean ?

Yeah, that's a texture import tag/setting. And as such out of my hands afaik.

I've re-implemented it as absorption color that refraction fades into over distance as you saw in the last screenshot, it's in the next version, but I still have bumpmap depth inversion left to implement before the release, so hopefully will release soon?

For the final version 1.0 I will probably release 2 versions of the shader one with all the bumpmap debug options and a lighter version that just has bump map depth/height multiplier, so as to make it lighter.

edit: oh and if I may ask, did the shader param's load for you in that order as seen on your screenshot, or did you tweak the order somehow? 'cause mine show up in a totally random order while in your screenshot they were ordered how I'd like for them to be!

Megalomaniak

Ok, water is colored again, this time by setting absorption color(make it dark-redish) and density(only helps along x & z, I don't have access to depth pass in shader).

All that's really left to do is figure out how to set up a secondary camera dynamically through a script and render reflection into real-time render target/texture.

This is something I'll likely leave up to the user at this point, because you need to implement it according your own player/camera controller.

Just search for planar reflection on google and you'll fine a whole bunch of resources explaining the concept. Once you have the render target captured it's just a matter of over-writing the shader's 'Reflection_Target' texture uniform through the script, at least in theory that's how I tried to set it up.

edit: removed v0.6 and uploaded ~~a bugfix v0.6a~~ now v0.6b(cleared out the bundled/unexpected internal texture references[wtf godot]).

Megalomaniak

quick post to note there was a bug(bad viewspace offset) in v0.6 refraction if you check the previous post, I've uploaded a bug fix version in there.
