Irrlicht Engine

Hello,

I would like to show several nodes based on the same mesh with a certain transparency.
The following code works, but affects all nodes at once, because I change the mesh to create the transparency:


node->setMaterialType(video::EMT_TRANSPARENT_VERTEX_ALPHA);
IMesh* mesh = node->getMesh ...

Idea to fasten it up:
pre-sorting of all vertices by their hash code with bubble sort (or something faster)
and checking afterwards only the "neighbors" in the list...

Hello,

I have written an application where two instances of irrlicht are running (via two different irrlicht dlls). Now I encountered the behaviour that one of them gets a lot slower, when the other has a lot to display.
They are executed in two different threads and should run on different CPU ...

Thanks Hybrid and Mel,

turning off the backface culling solved it.
I will check out how to manage turning the winding in Blender, but that seems to be a lot of detail work...

Hello experts,

I want to use some models and it seems to be that irrlicht doesn't use the right normals to display them.
This is how Blender shows my forklifter-model:

And this is how irrlicht displays it:

My problem with 64bit machines was caused by memory leaks and is now solved with the actual version.

Thanks RdR.

Does anyone have the actual source of the mesh combiner. The newest link is dead...

My mesh combiner crashes on some 64bit-machines while it runs without any problem on any x86 machine.
Does anyone have a clue why?

Thanks in advance

Hello Hybrid,

I found a strange solution for my problem, but it works :-)
My render loop is written in c# and is running in a separate thread, which I started via

RenderThread = new Thread(new ThreadStart(renderLoop));
RenderThread.Start();

For reasons I don't know, the rendering breaks down ...

Hello hybrid,

here's my console log:

Microsoft Windows XP Professional Service Pack 3 (Build 2600)
Using renderer: Direct3D 9.0

Present failed: DIRECT3D9 device lost.

Thanks hybrid.

If I generate a new device, irrlicht runs again.
But at the same time i have to create a new screenmanager and to recreate my models...
Is there an more easy way just to restart the device without deleting all my data?

Hello,

I'm rendering my irrlicht view into a form with direct3d9. Everytime the screensaver starts or I press crtl-alt-del to lock my computer, the irrlicht device gets lost and the rendering won't start again.
This behavior occurs with the irrlicht-examples as well (e.g. no.9 mesh viewer).

Does ...

When I set both flags to false, I had an ugly rendering result (but the flickering stopped).

Now I found a solution for me:

I set the rendering rectangle to zero:
SExposedVideoData videoData = SExposedVideoData(0);
rect<s32> rec = rect<s32>(0,0,0,0);
driver->beginScene(true, true, backgroundColor ...

Hi Mel,
that doesn't help.
The flags only prevent the refreshing of the buffer, but the "unrefreshed" buffer is painted everytime the WM_PAINT message is fired...

Hello,

for generating a video I am rendering my scene to a texture. I want to use the irrlicht-window to show the rendered texture as a video-preview.

Now I discovered that irrlicht clears my window, even if I set my rendering target to texture.
The result is that my preview is flickering.

Can ...
