scotty0351 Posted January 28, 2012 Posted January 28, 2012 I bought these assets and modified the LODs but I’m still not getting a good frame rate. I don’t know if this thick of a forest is practical in a game given the frame rate. Windows 7 64-bit Intel Core i7-2600 CPU 3.40GHz 8.00 GB RAM NVIDIA GeForce GT 530 Quote
Josh Posted January 28, 2012 Posted January 28, 2012 I have done much denser scenes at a high framerate. It's hard to tell how far off the trees are visible, and how dense they are. Distance culling is your friend. The smaller a plant is, the nearer the distance culling should be. This can make the difference between unplayable and good frame rates. It also appears you are attempting to fill the emptiness of the scene by adding unnaturally dense trees in the far distance. Ground cover will do a better job of this, and can be distance culled with no visible loss of quality. Add more bushes and rocks to fill up the empty forest floor. If you had twenty rocks visible onscreen, it would make the scene look like a real forest, and the rendering cost would be very little. Billboards can make trees in the distance cost pretty much nothing to render. There's a setting for the billboard distance in the vegetation options.

scotty0351 Posted January 28, 2012 Author Posted January 28, 2012 For some reason I don’t see the billboard option. Quote
Josh Posted January 28, 2012 Posted January 28, 2012 It should look like this: Quote My job is to make tools you love, with the features you want, and performance you can't live without.
scotty0351 Posted January 29, 2012 Author Posted January 29, 2012 It probably didn’t install right I’ll see if I can update it and see if it fixes the problem. Update: We’ll that didn’t work I’ll try a clean install. Quote
Josh Posted January 29, 2012 Posted January 29, 2012 It looks like your text resolution is really big, but I don't see how that would make a difference.

scotty0351 Posted January 29, 2012 Author Posted January 29, 2012 That reminded me I set my display to medium in the Windows Control Panel/Display setting so I switched it to small and now I can see the billboards option. I’m going to redo all the trees by giving them billboards and see how this works. Quote
Josh Posted January 29, 2012 Posted January 29, 2012 You don't have to redo anything, just click the option and it will work. Quote My job is to make tools you love, with the features you want, and performance you can't live without.
scotty0351 Posted January 29, 2012 Author Posted January 29, 2012 I thought I had to make the billboards myself but I guess not. I tried it out and I am seeing an improvement but I might have to modify the LODs further. I thought about adding rocks but my reference image didn’t have any rocks so I was trying to go without. I’m trying to recreate 12th century Duchy of Normandy (in modern day Normandy France) and I found some references of a forest near Rouen France. Quote
Rick Posted January 29, 2012 Posted January 29, 2012 The thing that stands out to me is those trees in your inspiration picture are much larger than the trees in your scene. Scaling them to be larger can help fill out your scene. Also you notice some trees that spider web out right from the ground and have leaves really close to the ground. You can see that on the left hand side of your inspiration picture clearly. That helps fill out the scene too. I would think more leaves than trunk and branches should help since leaves on most tree models are pretty close to what billboards are. Quote
scotty0351 Posted January 29, 2012 Author Posted January 29, 2012 I tried this arrangement about a week ago and looking at it I like it better them the first screenshot I took. Quote
Josh Posted January 30, 2012 Posted January 30, 2012 Turn on SSDO, make your ambient light dark desaturated blue, make the sunlight slightly orange and crank the intensity up, enable HDR, and that will look fantastic.

YouGroove Posted January 30, 2012 Posted January 30, 2012 Some trees have lot of branches, they should be displayed maximum details only on nearest range. Or try less branches, lot more LOD optimisations like : 3 sided cylinders for little branches, not more until you are very near ! Maximum cylinders of 5 , 7 or more polygons side only visible when you are in front. MipMapping can improve frame rate also. Shadows only on nearest trees will make you gain a lot of frame rate, i see shadows on far trees. Another technique is doing like UT3, you can use projected precalculated shadow sprite : texture projection that indeed is incredibly fast compared to real shadows. A game is AI, HUD, particles, characters, etc ... so your visual scene should run as fast and smooth possible before adding these elements that will also eat power Quote Stop toying and make games
scotty0351 Posted January 31, 2012 Author Posted January 31, 2012 Not having characters in the scene and still having a low frame rate is concerning so I think it needs a lot of work. Quote
Josh Posted January 31, 2012 Posted January 31, 2012 There's no way your FPS should be that low unless you have some setting really massively off. Distance culling would be the most obvious issue.

Michael Betke Posted January 31, 2012 Posted January 31, 2012 Yes colors are too saturated and your ground misses a lot of cover like fern if you want to match your reference pic. Quote Pure3d Visualizations Germany - digital essences AAA 3D Model Shop specialized on nature and environments
YouGroove Posted January 31, 2012 Posted January 31, 2012 Yes that's really strange ? When with LE i create a terrain a put lot more trees that these on the screenshot , all is running fine. Perhaps the problem is with polycount on trees ? or shadows ? Quote Stop toying and make games
Michael Betke Posted January 31, 2012 Posted January 31, 2012 I made a quicky with some plants from my shop. Still 45fps with default vegetation settings and around 12 vegetation types. 1 Quote Pure3d Visualizations Germany - digital essences AAA 3D Model Shop specialized on nature and environments
YouGroove Posted January 31, 2012 Posted January 31, 2012 I think the problem seems to be related to the models and scene settings. @scotty0351: Why not uploding the scene source (perhaps with modified (damaged) textures, to keep your copyrights) for LE users to test it under the engine and tweak settings, change models etc ... ?

Road Kill Kenny Posted February 1, 2012 Posted February 1, 2012 What texture size do you use? Do you have multiple textures per tree... If so how many?

scotty0351 Posted February 1, 2012 Author Posted February 1, 2012 First potential issue that comes to mind is I’m using the Day Night as my sky dome so I deleted that and had a jump of 3 frames per second. As far as texture size most are 1024x1024 and most of the trees are mult-sub object with textures for leafs (color only) and bark (color & normal). Update: Loaded the terrain_arctic and walking around I’m at 11 to 12 frames per second so maybe it’s just my computer. Quote
Michael Betke Posted February 1, 2012 Posted February 1, 2012 Terrain arctic should be fast. Its only one tree and two or three terrain textures. I think Josh did it for showing Billboards.

I don't think it's your computer because your's is similar to mine but with a better graphics card.
