Irrlicht Engine

I have this in my app for creating a shader:


id_material = gpu->addHighLevelShaderMaterial(
vs_code.c_str (), vs_main_name.c_str (), vsType,
ps_code.c_str (), ps_main_name.c_str (), psType,
callback, (E_MATERIAL_TYPE)material_type);


I use this shader for a time to render a object, later I ...

Do you render the head with an alpha material as well? It looks like the browes are rendered first, and blended with the background. Only then the head is rendered. You need to either switch the head's materials, or change the render order (probably by rendering the browes in a second scene manager ...

It looks like this:



Almost the same with MaterialTypeParam = 1.0. I would use shaders to fix this, but I'm using Irrlicht materials for whole scene, so I would have to implement a shader per object in the scene (lighting issues).

I have a problem using a texture with alpha channel. If I use

material.MaterialType = EMT_TRANSPARENT_ALPHA_CHANNEL;

then my mesh looks like this:

You can see that background is shown in mesh edges. If I use

material.MaterialType = EMT_TRANSPARENT_ALPHA ...

Did you see the VSM shadow demo? It can help a lot with that.

If that doesn't help then it would need to be extended with techniques like PSSM, there are some examples around but it can be quite tricky to implement.

Thanks for posting and help BlindSide :D . VSM shadow is great, but it only ...

I've been using XEffects for this week and it's a very nice addon for Irrlicht, congratulations BlindSide :wink:

It helped me a lot for creating real Ambient Occlussion, shadow maps are really easy to manage with XEffects. I only have a little "problem". If bloom and blur effects are disabled ...

You need to create the context such that it is shared with the one that Irrlicht creates. Please check example 14 (better in SVN, changes could be in Irrlicht 1.7 though) where I might have added a line to show how to do this. Otherwise google how to create shared contexts.

Thanks hybrid, now it ...

Hi, first of all sorry for my English.

I'm using wxWidgets and Irrlicht for a multiple graphic window aplication, concretely I'm using 2 Irrlicht Scene Managers in 2 different wxWindows. Everything works fine in Direct3D, but textures (using driver->draw2DImage) and fonts are not shown in OpenGL ...

According to the API the AntiAlias member is only used in fullscreen mode... so not sure how you can see Antialiasing even with Direct3D.

I thought the same, so I checked it again and it's true, AntiAliasing is there for DirectX in windowed mode.

Did you check material settings?

You need to ...

I'm trying to activating AntiAlias in windowed mode using OpenGL. I'm using:

SIrrlichtCreationParameters param;
param.DriverType = EDT_OPENGL;
param.AntiAlias = 8;
device = createDeviceEx (param);

But it does not work. If I try with

param.DriverType = EDT_DIRECT3D9;

then it works. Am I missing ...

Sorry for posting so late, I have been very busy working.

The example I use to reproduce the it's the same as writtern in first post. Just creating two spheres and render them using render buffers. Then using a textured quad to represent the scene.

My graphic cards are dual 9600GT in SLI mode ...

No luck with 1.7.0 version

It's strange, the problem is at AntiAlias in SIrrlichtCreationParemeters. When AntiAlias is off, renderbuffer it's OK, when it's on, renderbuffer ignores zbuffer.

Another problem: I tried to render with OpenGL and I have the same problems tha this guy: http://irrlicht.sourceforge.net/phpBB2 ...

It would be related with my problem:

http://irrlicht.sourceforge.net/phpBB2/ ... ht=zbuffer

I'm using Irrlicht 1.7.1. Have been fixed?

Hi all, first of all sorry for my English.

I'm having a few troubles rendering to texture in DirectX. It seems like it does not use zdepth information when rendering to texture. For example, a mesh is painted overlaying other mesh that should be in front of first one.

If I render directly in ...
