Edging proxy grass

[Peter M. Gruhn]

I'm using mrProxies and ObjectPaint for gravel and grass and they're finally starting to look... OK. But I have hard edges areas into which they must lay. Are there good ways to deal with getting nice crisp edges?

 

The only things I can really come up with

- delete the proxies that over lap the edges and use object paint with real geometry then delete mesh. This sorta kills some of the proxy advantage

 

- use a cutoff map over the whole collection

There is another thread similar to your question at the moment about multiscatter, with the great idea from someone that uses grass-o-matic to create only the hard edges and blend it into the proxies.

I think that was me in the other thread. I'll post it here too. I'd love to see how others handle this, as I'm not completely satisfied with my results. My grass is a little too "perfect", but it's good enough for me for now and I haven't had time to work on adding imperfections yet.

 

I prepare my terrain mesh by detaching an 18" wide strip along whatever edge will be visible from the camera. Then I use Object Painter to paint a 2'-3' diameter grass patch proxy across my terrain mesh. If I have a larger area, I'll use something more in the 6' diameter size range, but those don't behave very well on bumpy terrain. The 18" boundary acts like a layer mask... the proxies will overlap that 18" strip, but they're not big enough to reach the edge and "grow through the pavement".

 

Then, to create the hard edge, I use the Grass-O-Matic plugin using the 18" wide strip as the source. It overlaps my proxy patches, and the result is usually pretty seamless. If you didn't want to use Grass-O-Matic, you might be able to achieve a similar result by using a very small (a few blades) grass patch proxy for the edge strip, and the larger patch to fill in the rest.

I'm such a noob. I had even looked at that thread a couple weeks ago. Thanks.

Not too much effort and I'm getting near adequate results. I think my big issue is probably texturing and personal skills. The solution is better than I am. Thanks again.
