I am trying to make them work, but I get these errors:

They work seperately, but when I try to combine them, it fails.....

Looks like they have the same function defined twice, I am not of way to fix this besides editing the source code of one of them.

You can try using the /FORCE:MULTIPLE linker option to see what comes from it. You have to add it manually to the command line option of the linker settings...

Keep in mind that forcing multiple only links the first one encountered! So, if DarkShader is referenced first, it's versions are linked first. Likewise for DarkLights. Therefore, if it doesn't work, try reversing their link-order (order of specification in the LIB settings).

If it still doesn't work, then I would say that they can't be used together...

Good Luck and let us know,

I tried your suggestion. The errors went away, but when I run the program I get some kind of error (it's not specified). All possible combinations give me the same result. It just says "(program) has stopped working blah, blah, blah...." and it terminates.

Here is my goal:
I want bloom/HDR
I want shadows (static and dynamic)
I want them at the same time.

Does anyone have a suggestion that doesn't involve me buying more stuff that won't work together?

Create one project where you use only dark lights. Use it to calculate lightmapping on your objects.

Create a different project where you just load that lightmapped objects and use dark shader to apply effects. You don't need dark lights to load lightmapped objects so there's no need to have both, dark lights and dark shader in one project

That't encouraging and disappointint at the same time.... I'll give it a try.

What about dynamic lights & shadows?

Ok. Now I have another problem. I can't save the scene in dark lights. What's the proceedure?
I start out with the default house.
I place a light.
I press F5.
I type in the name.dbo.
That brings me to the "light map" screen.
I press Enter and get a windows error and exit.....

Dark lights is only for static lights. Dynamic lights and shadows can only be made with shaders.

Are you using the editor that comes with dark lights?
Few people have experinced problems with it.
It's probably the best if you compile it yourself or create your own editor

I'm using the one that came with DarkLights. I downloaded both the GDK and DBPro files. The editor is only in the DBPro file. I thought about making my own editor, but how do I save the files and how would I load them after? I looked at the DarkLights refernece file with all the commands and there is nothing for load/save (that I can tell). Am I looking in the wrong place?

dark lights automaticaly saves the lightmaps in the "lightmaps" folder (i think you can specify the folder name, but if you don't default name will be used).

Lightmapped objects you can save with SAVE OBJECT command. Loading is done with LOAD OBJECT command

Thanks. I'll have to make my own editor I suppose... I've done that kinda stuff before, but I didn't know that lightmapped objects would save the lightmap info. Thanks.

The only problem is that I want dynamic lights and shadows. I'll take what I can get, but if anyone knows how, please post.

As i said, that can be accomplished only with shaders.
If you want to have static shadows (made with dark lights) and dynamic lights and shadows with shaders you'll have to modify each shader you use to take the lightmaps into account.

But, if you want dynamic shadows with dark lights that just can't be done because the proccess of calculating shadows is to slow and thus can't be used during run time, thats what shaders are for. Check Evolved's web page, he has done a few different shadowing techniques

I was able to make Evolved's "ShadowMapping.fx" to work (the exe that it came with didn't work). The only problem is that I can't seem to modify it to work with multiple lights. This should normally work, but I'm not sure it will. Would you (or someone) be willing to take a look at it and figure out what I'm doing wrong? I basically made another pass for the shader that uses another light source as input. I believe the problem is in the "DepthMap" section. I just don't know enough about shaders or the math involved to figure this out myself. I've tried several variations and this one is the best I have come up with.

I can take a look but can't promise anything. I suggest you to ask green gandalf or evolved (they are shader gurus)

My university life became to hard so I put it on hold 2 years ago.
Also, combining C++ plugins with dbpro became to difficult.
Also, figthing with all the dbpro bugs and limitations started to fry by brain cells. Few months ago i started to port everything to pure C++. I'm currently working on terrain rendering/creation part.
