Grass stones

Hi!

Any suggestions on how to make grass stones as in the picture in Archicad?

It has to be in 3D and grass is a different material because it will be changed in the grass than in rendering software.

My idea is to make them from slabs and copy past all along 😄 am wondering if there is any other way?

Thank you!

If it is going to be flat then model a slab for the grass.

Small slabs (or short columns) for the bricks - slightly higher than the grass slab.

Distribute using the multiply tool to form the array.

Perform a Solid Element Operation to cut the bricks from the grass.

Render away.

If not level you could do the same with a mesh for the grass - adjust the top surface levels as you want.

Set up a grid of lines in plan for the centres of the bricks.

Then gravitate columns to the mesh using the grid as a guide.

This will automatically set the correct levels for the bricks.

Hi! Thank you for answering. Distributing slabs sounds most logical to me, but without SEO - it slows down Archicad too much.

So, there´s no way to use it simply as a texture?

I am sure you could find or create a texture for this.

But you wouldn't be able to change just the grass which you said you wanted to do.

Also as separate surfaces, you can apply real 3D grass in your render.

You might get away with out SEO, but I was thinking if you apply real 3D grass, would it show up through the bricks as well?

I can't say I have played around with this much in renders.

If it is a slab, you could also multiply (array) holes in the slab.

Then fill the holes with your brick slab/column.

Hi! Yes, I need separate surfaces, so I can apply 3D grass. Thank you for your help, will simply copy-paste slabs a bit dipper, to avoid using SEO.

To speed up the process, I can actually make an object out of a few slabs and then copy-paste that.

Or just use the multiply/matrix option in the pet palette.

Could you make it as a Curtain Wall? Concrete panels, grass mullions?

Unfortunately the unloaded catalog surface textures have these but not to the same style. You could try to create your own surface texture using the SEO technique suggested by Barry and render from above to create an area (say 2m x 2m?) that you can use as a new texture. I would just be a bit concerned of creating too many polygons for rendering if you model a large area in 3D.

Oh, thank you!! 🙂

Hi! sounds interesting, but I don´t have many experiences with the Curtain Wall. Do you mind posting a screenshot if you have time, how would you set it? Thank you :)))

200 x 200 panels in concrete

80 wide Built-in Butt-glazed Frames with no panel overlap in grass

Hi! interesting solution, that would also work thank you!

In the best-case scenario, I would have some kind of texture (3d texture), which I could apply on paths. There are many paths with this kind of pavement, and modeling/adjusting for each takes some time ...

But workaround with curtain wall or saved objects with multiplied stones works also.
