G'day,

I'm a new user and I'm hoping this is an easy question...

I don't have a super big computer (Macbook Air... i5 8Gb ram) so that is most likely causing the issue.

Applying grass to a surface in my scene is causing my computer to eventually grind to a halt. I cleared up as much disk space as possible (40 Gb) and that is still not sufficient when I go to render or use Fire. I've had no trouble when using it on smaller areas but this is a bigger area surrounding some buildings, and so I understand that it is a bigger hit on processing...

Is the only way to get around this on my current system, just to not use grass on larger areas?

Thanks muchly for the much needed help

Grass blades are not instances, so you are probably hitting your RAM limit. A workaround could be to generate a small bunch of grass and scatter instances of it over the ground object. That will save lots of RAM.

If your camera point of view is lower, use the Level of Detail (LOD) feature of the grass:

Code: Select all

It's not the diskspace that matters, but amount of RAM in your system. You can also try to lower the nr of points per grass blade also, which will require less RAM. But it's the LOD parameter that can help the most if you want grass over a large area.
