Hi, those screens look good
I really dont understand much about shaders, can you explainme how can I add new or my own shaders to XEffects from a file? I just managed to load the ones you released with XEffects....
Any idea when will you release v1.3?

at first: excuse my bad english
XEffects doesnt work for me. I try to link it into a DLL but i get the following errors:
1>EffectHandler.obj : error LNK2001: Nicht aufgelöstes externes Symbol "__imp__rand".
1>EffectHandler.obj : error LNK2001: Nicht aufgelöstes externes Symbol "__imp__srand".
if i compile the examples all will work fine.
any idea anyone?

That's really strange. Your errors are in another language but it seems that it can't find rand() and srand() which should be standard. I've never attempted putting XEffects into a seperate DLL, it's not really large enough to warrant that.
You'd have to fix your compiler settings for this. I'm afraid there's not much I can tell you from an XEffects point of view on this subject, it's a compiler/linker settings problem. I recommend just including it in your project files.

It gives you the header to include. Figure it out from there.
Sorry,does XEffects fit a larger scene than a room?

Can It make every character generate good shadow in a large map?
I've contacted XEffects few days,, still have wondering on this,,sorry

i've solved the problem:
at first i compile effecthandler.cpp as "multithreaded" ... then i can link the project as "multithreaded dll".

ok, i try it again in english ...
my scene is complete black with shadowmaps ... i've tried different settings in addShadowLight, but nothing will help. Can anyone explain me the parameters near, far and fov?!? Why must a lightsource "look at" a position and where should this position be?

Only spotlights and directional lights are supported currently. That's why it must "look" at a position. For the specific terms think of them from a camera's point of view. Google for "3d camera fov", etc to learn more.

Getting shader errors on an NVIDIA Quadro FX 570M 512MB.
Code: Select all
HLSL vertex shader compilation failed:
error X3506: unrecognized compiler target 'vs_3_0'
This video card is using shader model 4.0.
Using a forced vs_2_0 shader model, the program runs correctly.
I'm using the Irrlicht 1.6 engine, with pre-build binaries from the website.
Running it with dx 9.0c.
The example bins run fine when I open those, but when I recompile the examples and run, the std output gives the same errors as mentioned above.
Any suggestions to fix this in a proper way instead of forcing vs_2_0?
Edit:
Here's a link with screenshots of the prebuild run and the rebuild run.

this thread has over 9000 of the same question, you should read back a few pages and you should find an answer pretty quickly

The last screenshot is attempting to run on OGL , with directX shaders? Either that or its an ATI card. Nvidia cards sometimes allow HLSL in GLSL shaders... Change the float2 to vec2 inside the shader.
Could not load shader function D3DXCompileShader from dll, shaders disabled: d3dx9_42.dll
This seems pretty self explanatory. The DX SDK changed recently, i would assume that there is something to do with this. In irrlicht its using a function that has changed in the newer SDK's. Using an older SDK, should work fine.
OR, post a patch/bug in the tracker about updating the shader compiler code to match new DXSDK's.
