Irrlicht Engine

I use Direct3D9 debug runtime and this two lines contain memory leak, which detected by D3D9 debuger.

Memory leak inside:
void *pTexData = pTexture->lock();
pTexture->unlock();

Ok, thanks. How I can fix this bug?

Sorry, DirectX 9.0 only

hybrid wrote:No, not yet.

Does another way exist? I need load cubemap for HLSL shader.

hybrid wrote:Works for me. Which driver do you use? You should also get the latest revisions because I fixed some stuff (which might be in 1.3.1, though, I'm not sure).

Engine version is 1.3.1 My videocard supports 8 textures. Video card driver info: 8.342.0.0, 02.02.2007, Ati Radeon 9800

How to increase max count of material texture? I tried to change: //! Maximum number of texture an SMaterial can have. const u32 MATERIAL_MAX_TEXTURES = 4; When I had changed value and recompiled engine, engine crashed. When I call any function from recompiled engine, I have random probability to ca...

Does irrlicht support cubemaps? How to work with it?

How to use it? Can you give me example?

I found solution:
void *p = ->lock()
getColorFormat
...

But how to save my modified texture to file?

How to change some pixels on ITexture?

Thx. I found my mistake.
The weightABC is pixel shader constant. So it means that correct constant setup provided by services->setPixelShaderConstant

Thx My solution: bool g_IntersectLinesFast(const core::line3df& _a, const core::line3df& _b, core::vector3df& out) { core::line3df a = _a, b = _b; a.end -= a.start; b.end -= b.start; f32 t1 = 0.0f; f32 t2 = 0.0f; bool bCalculated = false; //by Cramer f32 det = 0; //XY if(!bCalculated) { ...
