COLLAB2021 – If You Wanna Have Some Fun – NATURE FG

[spikeyxxx]

Multires linear vs. smooth:

Still have to figure out what is actually happening…

[yukino hatake]

Nice, the edges in linear are still sharper then compared with the smooth one 

[Matthew Ullrey]

That is a fun comparison between the two. It is nice to have these visuals to really understand what is happening.

Hey folks,

im not sure how we are expected to tackle the Grass this Week. Since we have no Locator based Item but a more dynamic one heavily dependant on the Ground Plane im really not sure how to go further. 

@spikeyxxx Do you have an idea?

How about working together on this?
I think our approaches are more or less close so maybe we can join forces so the result might be better than anybody of us could do alone.

[spikeyxxx]

The grass is indeed dependent on the ground, but we can refine the technique that we wanna use, so that it can be applied to the ground plane, when that is ready…it also depends on the objects that are on the grass (not the flowers), like rocks and cart…

I wouldn’t want grass blades intersecting with those objects, so we need a system that can easily adapt to objects in/on the grass.

The ground plane is the least of our problems, as we could even use Shrinkwrap, when we would have ready patches…or apply the Particle System or Geometry Nodes directly to the ground….

So I hope to get it in a state, that as soon as someone gives me a ground and rocks etc., I can ‘apply’ the grass where it should be.

I would hand-paint the colors, but leave that for next week, when Texture Painting is planned.

Of course we could work together on this. I did all those tests that you did and the worst result was with ‘grass cards’, especially on the edges!

But like I mentioned, there are large areas, that only seem to give the illusion of grass, without any actual blades..at least that is my idea and it would be not too taxing on the scene, polygon-wise….

I don’t know if this would be of any help to your team or not, but I came across this just recently on Instagram.

I know that it’s far more hyper-stylised than what the Collab is aiming for (so ignore the trunk be all means), but I thought that this might be a helpful visualisation of what Kent @theluthier meant in the 2nd Live Stream by breaking up the shape of tree’s silhouette with a few smaller leaves. Hopefully this will useful to some of your team. Keep up the astounding work. @spikeyxxx  @wardred

Anyone like my rocks? Please Critique as much as possible. Like, do I need more detail or anything.

[the3dbanana]

Wow! definitely add this to the reference folder on the google drive.

[Kent Trammell]

haha that is quite cool 🤩

[Kent Trammell]

I just have to say I feel validated in my confusion if @spikeyxxx doesn’t even know what’s going on with these methods 😅

[Kent Trammell]

I’m really glad to see you both teaming up. Spikey is exaclty right about how to approach the grass: Until the ground is finalized, you two developing a good system of applying beautiful grass to any surface is ideal. 

Also for week 2 I’d like to see some refinement of the style of grass to get a bit closer to the art. Sorry I haven’t given stylistic feedback to you yet @spikeyxxx – You must be in the last ~30% of submissions.

What we see in the image is the classical painters approach, you only need to paint Grass where color changes and where it influences the silouhette. 

It depends heavily on the Camera Where you need some Grassblades and where not. But maybe its just as simple as turning the numbers down, for example using 100 instead of 5000 in the density settings.

My current idea is to use weight painting for populating the ground plane just on the spots where we need it to be populated. So you basically place everything else and then simply paint grass in where needed. Combined with some Ground Texture this could be a solution at least in my head.

When looking at the artwork, it seems to me that the rocks have slightly imperfect flat surfaces, and that most fine details are on the edges:

[the3dbanana]

Ok, I’ll change that

[rstich]

in my humble opinion you need sharper edges. It looks a little bit like these are bulges followed by a dent instead of edges.

Stones have usually sharp edges unless they are formed by the Waterbut then the surface is very clean.
You get it on some places maybe you just got carried away.
