![]() ![]() I am not sure how well Toms VolumeGrass performs on huge terrains but its a good way to get a nice basic density and then use unity grass only for accents and extra variation. also to get more visual denisity its best to make the grass a bit higher than what would be realistic but dont overdo it. Another thing i noticed lately its also good to make your grass blads not start all at the same height on your grass textures, this have to be done carfully as if you put some grass blades too high above the ground they will appear floating, but if done right it will break the flat apearance of the grass billboards/planes a little bit. Then if this is still not enough density(most likely the case) you have to use more grass textures, which will give you double density with every grasstexture you add, the benefit is also that this way your grass can have more variation, the downside and that is with grass on unity terrain in general that it affects performance really badly so try to use as little grass as possible, for example its a good idea to match the bottom side of your grass textures with the color of your terrain grass textures. i am referring to the 2 values at the top which say 128 and 8 at your screenshot. The next thing is to crank up your grass resolution much higher than you have it. I know this problem, lets see if i can help you with what i remember.įirst thing to do would be to set your "grass per patch" to 16 or 32, the higher this value the more likely you get little hiccups while movement, this is not affecting the framerate overall but just gives loading spikes, there is not much that you can do about this as its again something that unity just does not handle very well to say it in a friendly way. I found that if I put the mix rate to 30, I get somewhat more grass. You can't see the grass picks, but the Strength is 1 and the mix rate is 0.5. Here's a screenshot of my scene and the Grass layer + resolution. Rainer again - how did you get such a beautiful coating of flowers and grasses? Now with my 5000x5000 terrains, 1.0 strength makes my grass extremely sparse (like a grass every 2 meters). When I had 1000x1000 terrains or even 2000x2000 terrains, i had to push the grass strength up to 1.0 to get an acceptable lush "field". Though I do have one question which cropped up now that I am using bigger terrains. I tried it a few minutes ago with 4 terrains at 5000x5000 with 2048 splatmaps and it works MUCH better! I loose a little detail but at least I can work with it until Unity 5 comes out! but thanks so much for the hint, now I can keep moving forward! Thanks a lot for the advise! I had often thought about whether fewer tiles was actually better/worst than more.
