Well, we're clearly not in the real world of programming, and I guess this engine is not on an equal plane to other engines on the market today.

There's a crazy sale on Steam right now. If you haven't played STALKER yet, you can get it for $10: http://store.steampo...check/app/4500/ In other news... Framework is being compiled into the engine DLL and being made an official part of the engine API. It will remain a separate piece of code for BlitzMax programmers they can just import. A mechanism will be added to add your own custom post-processing effects, though this will not be available immediately. It will be something like this: CreateEffect( callback ) EnableEffect() DisableEffect() FreeEffect( effect ) If you prefer to use the existing C++ code you are free to do so. However, the integrated framework code will allow Lua to access the Framework commands, so your scenes will work seamlessly between the editor and any programming language you choose. The whole design of our buffer/shader system and framework makes a heck of a lot of sense now. It just had to be allowed to evolve so we could determine the best solution. You've got an the easy-to-use framework commands, but still have the low-level buffer and shader stuff which can be used to do many things. The Lua command set is also slowly being exposed. At first, it will just have the bare minimum commands you need to set the variable "fw" to the framework object you create in your program. In time the entire Lua API will be exposed through the DLL. This will allow limitless extensibility for whatever you want to do with Lua. You can expose your own C++ or other functions and classes, or do whatever you want.

I think for nighttime scenes a somewhat desaturated dark blue is good for ambient light, and a white slightly blue light is good for moonlight, with the intensity set pretty low. Unless you want it to be dark for a reason, don't make it too dark. Rely on the blue tint and keep it bright enough to see. You'll notice this technique used in movies a lot.

There may be some fixes for 2.28 but there's lots of other stuff I need to do first.

Well, I don't think you are giving away any valuable secrets in this thread. I just moved it because it seemed like an editor question. There should still be some discussion in the general forum because then the existing users will still go there and it doesn't become silent. And it also gives people a glimpse at how the community interacts, and how people go about making a game. Now if an unknown user starts asking programming questions in the general forum, that's when I become suspicious, but those cases are pretty obvious.

You actually can get antialiasing right now, and not the edge antialias shader. Just render to a double-size buffer, then draw this onto a buffer half that size, with the smooth texture filter set. This will produce about the same results as 2x MSAA. I don't recommend using this technique for anything you release, because the bandwidth usage would be ridiculous, but its okay for testing.

The space limit is raised. Please use better compression for your images.

Can you post a demo showing how 20 character controllers are slow?

I think you will get the most bang for your time with Lua.

To edit the terrain heightmap on the GPU, I create a small buffer and copy part of the heightmap to this. Then I enable the terrain editor shader and draw this small buffer back onto the same spot on the heightmap buffer: Strict Import leadwerks.ENGINE Import "terrain.bmx" Import "Globals.bmx" Global

I think it looks good. They're using a forward renderer in that shot, which can be good in an outdoors scene with one directional light. However, it doesn't allow for shadow-casting point or spot lights. With MSAA the edges of trees and small objects will look a lot smoother, pretty close to that image. MSAA will be added when the engine is updated to use OpenGL 3.

A 4096 shadowmap size means a texture that is 8192x8192 will be used. Grass shadows are adjusted on a global (options>configuration) and per-layer basis.

Yes you can. Turn off shadows. Left 4 dead uses a combination of static lightmaps and single projected shadows, with vertex colors for lighting of dynamic objects. This is the approach I used to use before version 2.0 came out. I will never again implement a bsp-based engine like this. One consequence of a uniform lighting model like STALKER and Crysis use is that on low-end cards the older engines may actually look better than the newer one with settings lowered. The same was true when HL2 came out; the fixed-function renderer was so simple it looked worse than Quake 3.

It's easier to desaturate a saturated image than saturate a desaturated image.

I don't really care. I can see you are a 2.3 owner, so it doesn't matter to me.

I guess everyone is saying you can if you are willing to learn how, but they also want you to know your chosen genre is one of the most ambitious out there.

It may be available within a week.

I would wait and not do this right now.

Working to improve the implementation of the code known as framework. It needs to be able to talk to Lua, with all programming languages. I can't really go on documenting the script until this is finalized, so the time to do it is now.

Fog?

The X1550 actually isn't supported because it can't perform texture lookups in the vertex shader, which is why the terrain maps crashed.

Ah, I think he just used one of their tools to make renders.

On the left is the Aion image resized to 3x3 and upsampled. On the right is yours. The difference is saturation.

I hired this company?

Intellectual property is certainly a convention like a patent or trademark is, and not the same as a physical object. However, if you want a market for software to exist, it is necessary to adhere to and enforce this convention.
