Landscape settings? I just made that by hand, then some displacement procedural maps.

Jakroval · November 1, 2019, 3:49pm

How you keep those particles within the boundary? Is there a check box ?

Acrivec · November 1, 2019, 3:50pm

In what boundary?

Rixtr · November 1, 2019, 3:54pm

yes but although i am a longtime blender user,i do suffer from multiple tbi.
this kind of landscape design is new to me.
such as,did you use proportional editing for the land plane?
or a custom displacement map?
and what is the map thingy black and white for dispertion of the elements?
that type of thing.please be patient i am not always on top of things.
Peace!

I have a plan, and want all the particle to stay within the boundary of that plan or face?

Acrivec · November 1, 2019, 3:59pm

I mean, particles won’t appear outside of the plane, because the plane is the emitter?

Follow Blenderguru’s meadow tutorial for that

Thanks for the help

I’m interested!

it’s awesome addon !!
can it do something like LOD ?? it will help a lot with rendering , especially for eevee

thanks

i’ll see that for later features.it should be relatively easy to code but well…
lod is really useful for real time game engines, but for rendering it’s not really useful at all.

What if grass got replaced with cards in the distance?

BD3D · November 5, 2019, 1:45pm

could lead to huge transparency problems.
rendering all the transparency could take more time than just more geometry

maybe for more simple cases like forests, it could work

Balda · November 5, 2019, 1:45pm

The grass you show in the first post of this topic ist just excellent!
I still don’t understand how you clustered tthe patches

BD3D · November 5, 2019, 1:46pm

Thanks
well witouth the addon it’s quite complex if you are new to blender.
even if you are not, it take a lot of time.
fortunately my addon will make things much more accessible and done within two clicks

captainkirk · November 5, 2019, 1:48pm

You’re probably right. I imagine for trees it could work really well.

Balda · November 5, 2019, 1:49pm

I can’t wait…
No, wait, actually we can wait…
Take your time to polish your gem!

thanks balda

The point is how to set area on terrain so they remain dynamic.
Vertex weights are pretty damn slow on huge terrains and require geometry pre-processing - a vertex weight modifier based on distance from camera as object.
Maybe a gradient based map could do the trick ?
And none of those will not work in animation context.

BD3D · November 5, 2019, 1:57pm

gradient based map could do the trick ?

unfortunately the texture editor is too broken

Acrivec · November 5, 2019, 3:54pm

Not could, but will. The only way of making stuff faster with LoD wound be:

Reduce texture size depending on distance with quantized steps - for example 100% → 75% → 50% → 10%
reduce geometry amount with decimate, that should be possible to accomplish but could produce artifacts in geometry - i.e. decimate would have to be material limited, and as of those are particles you can’t really give a modifier to each of them separately, so you would have to limit it in quanited steps like with texture size
remove transparency ----> material optimization as in Graswald
Add gradient-like density, as in Meadow tutorial, that’s easy to do and shouldn’t be a big deal with current options you have right now
