Irrlicht Engine

The previous link does fix some things. The emitter than emits based on the rotation of the parent, correctly. But the textures are still upside down. HOW TO FIX UPSIDE DOWN Particles. IN void CParticleSystemSceneNode::reallocateBuffers() replace Vertices[0+i].TCoords.set(0.0f, 0.0f); Vertices[1+i]....

That fix does not help with this problem. It has to do ONLY when it is part of a particle system or has a parent which is rotated. The particles get the transform of the parent and the billboard gets rotated. (Or something like that!!)

The problem is, I just can't seem to fix it!!


Please Help!!

Has anyone worked on Cg shadow volumes?? Is this possible with the current state of shader support in Irrlicht?

Does anyone have a fix for the first problem mentioned in this thread? If I change the PreRendering code in CTextSceneNode from SceneManager->registerNodeForRendering(this, ESNRP_SHADOW); TO SceneManager->registerNodeForRendering(this, ESNRP_TRANSPARENT); It now doesn't mess with the shadows, but th...

Another tip:

uncomment the line

//#define CAL_16BIT_INDICES

in cal3d - globals.h

Irrlicht uses 16 bit indicies anyways!!

This can help. It won't solve all your problems. From my understanding, to correctly fix this is not trivial.

Changes to CTextSceneNode.cpp void CTextSceneNode::render() { if (!Font || !Coll) return; ///////////////////////////////////////////////////////////////////// video::IVideoDriver* driver = SceneManager->getVideoDriver(); ICameraSceneNode* camera = SceneManager->getActiveCamera(); if (!camera || !dr...

I did figure out that when using addShadowVolumeSceneNode, if you set the zfailmethod = true and infinity to a smaller value like 0.5f, it clips the shadow volume which you could then tune to keep it from displaying to far. FYI

I am starting to use Stencil shadows. They seem to be working good for me. BUT, they are displaying thru things. EX: If I have an overhead light with an object on a table, the shadow is displayed on the table AND the floor. Has anyone been able to fix this. I could fix this if someone could help me ...

Does anyone have additional performance improvements that work with DirectX and OpenGL they would like to share?

I have included one big one in this thread.

I also switched to getVerticesNormalsAndTexCoords, which didn't seem to help to much.

You can dramatically speed this up if you make SMeshBuffer mb a member of the class and don't do the clears. DON'T DO mb.Verticies.clear(); mb.Indicies.clear(); They clear all the memory and the memory has to be reallocated. Do something like this in the constructor mb.Vertices.set_used(2000); mb.In...

I had the same problem. Seems Irrlicht doesn't like PNG's with 1024 width.

In file CImageLoadedPNG.cpp, around line 205

Original

if( bytes_per_row >= (int)sizeof( g_png_load_buffer ) )

TO

if( bytes_per_row > (int)sizeof( g_png_load_buffer ) )

I get this problem also. Has anyone had this same issue and fixed it? My window needs to be NOT resizeable.

OK, Lets try this again. In the Irrlicht.h (DON'T FORGET their are TWO Irrlich.h file) Replace the similar section with #if defined(WIN32) && !defined(IRRLICHT_STATIC) #ifdef IRRLICHT_EXPORTS #define IRRLICHT_API __declspec(dllexport) #else #define IRRLICHT_API __declspec(dllimport) #endif /...
