How to render the grass ?

[dadou351]

I would like to know how to produce of the grass with Octane Render?

I know that on 3DS Max there is a function Vray grass and which is very useful.

About proxies, does it work on Octane Render?

Thank you

Here it's a project with Octane Render :

I tried to create a large grass field using square billboards supported by a subdivided plane, using Blender Duplivert feature, and rotated and resized randomly.

The Billboard image is a photo taken in close up of a simple tuft of grass. I have erased some parts by hand on the photo to allow transparency and kept some lone grass blades.

I'm almost sure that starting from a simple plain green color in Photoshop and adding a bit of details and color variations would almost work the same.

The image shown is only a trial. Adding various kinds of billboards with some flowers or longer grass blades would give more life to the scene.

It worked well, except one thing : I had to take care of the direction of the sun, because currenly transparent materials still cast a shadow, and the small planes were shadowing each other, creating sometimes bad dark shapes.

I attach an example of my trials, but I'm sure that you will find some better visual examples in the gallery.

I really hope that future releases will solve this problem of transparency.

Many billboards means memory consuption. Instances will be also welcome to create grass using less memory.
