Irrlicht Engine

I made two .x files: "mesh.X" contains the mesh and bones "anim.X" contains the bone animation I tried to add 3 nodes with different animation speed. here's my code: IAnimatedMesh* mesh = smgr->getMesh("mesh.X"); ((scene::ISkinnedMesh*)mesh)->useAnimationFrom((scene::IS...

Thanks for your help~

does anyone know how to solve this problem?

i want to make my own tangent space normal mapping shader.
in HLSL, i can get the position, normal, texture coordinate through POSITION, NORMAL, TEXCOORD0 respectively.
however, i cannot get the tangent through TANGENT.
how can i get the tangent in HLSL?

This is really a nice framework~!
but I don't understand, why we don't need to delete the object created by 'new' method?
how can i remove an intermediate stage?

problem solved..... i have added a new empty sprite bank, but it don't have any sprite in it now i added a sprite (with a single frame) and it works //add an empty sprite bank gui::IGUISpriteBank* sb = guienv->addEmptySpriteBank("my button"); video::ITexture* texture_up = driver->getTextur...

If you really debug your app you'll aslo see the stack trace and the debugger will point to the problematic code section. That's the really important thing. it always pointed to "env->drawAll();" Are you sure all the textures exist and that the getTexture function is not returning 0 (NULL...

what does your debugger say when it crashes? :p you could check out my IGUIFileSelector which I put in the Code Snippets thread a while ago, that uses a sprite bank, i do remember they were a bit tricky to handle... it said "Unhandled exception at 0x1001d0c2 in sc_viewer.exe: 0xC0000005: Acces...

i want to use button->setSprite() to make my button use different texture image on different state. however, i don't know how to use the sprite bank my program just crashed after i clicked the button. here's my code: gui::IGUIButton* button= guienv->addButton(core::rect<s32>(core::position2di(500,40...

this question has been asked by sunzhuo before. we cannot initialize MAYA camera position.....
is it possible to add one more parameter in addCameraSceneNodeMaya()
or provide serializeAttributes() function,
so that we can change the camera position??

texture matrix is applied correctly when I use EMT_SOLID material type
however, the matrix is ignored when EMT_NORMAL_MAP_SOLID is used
how can i fix this problem?
if i want to write my own shader, how can i get the texture matrix?

In ECOLOR_FORMAT there is no floating point color format
does Irrlicht support floating point texture?
if yes, how can i create it?

I have made a character model with bone animation the sampling framerate is 60fps and the animation has only 10 frames (1/6 second) I exported it in .X format, and the exported file is correct (viewed in DirectX Viewer) after loading into Irrlicht, everything is fine except the animation speed, it t...

Just a thought.. what's "time"? Is it some huge number converted from u32, causing the texture matrix to have a massive Y translation? thanks for your help~! you pointed out the problem :shock: "time" is the system time. it seems too big for the matrix i fixed it and now it work...

a shader can also do that quite easy in fact... the realisticWaterScene node for example moves the bump linear, but I guess if you move 2 or 3 good layers blended (one layer with sudden changes for bubbles and one smooth foam and somehow out.color multipield or added... try) it would look quite nic...
