[DX10] CreateTexture2D from TGA

i've got my tga loaderfrom my old opengl engine, and now i'm stufing around with a dx10 engine and want to get textures loaded. so i've got this: where tga.GetPixels() returns a pointer to the image data. tga.GetBPP() = 4, tga.GetWidth() = 512, tga.GetHeight() = 512 CD3D10_TEXTURE2D_DESC desc(DXGI_FORMAT_R8G8B8A8_UINT, tga.GetWidth(), tga.GetHeight()); D3D10_SUBRESOURCE_DATA data[1]; memset(&data, 0, sizeof(D3D10_SUBRESOURCE_DATA)); data[0].pSysMem = tga.GetPixels(); data[0].SysMemPitch = tga.GetBPP() * tga.GetWidth(); int bpp = tga.GetBPP(); HRESULT hr; hr = static_cast<const DX10Device*>(device)->GetD3DDevice()->CreateTexture2D(&desc, data, &mTexture); if (FAILED(hr)) return false; the problem seems to be the second paramter to CreateTexture2D. If i make this null i get S_OK returned, if i pass in data as shwon, i get E_INVALIDARG

Sound like your user account has not enough rights to change this.

If it was not clear : the reason it fails is because you pass a texture2d_desc with the usage flag DEFAULT, AND at the same time pass an initialization structure.
This is only legal if you used the usage flag IMMUTABLE, with the restrictions of that usage flag (no rendertarget, no zbuffer, no locking (map), no autogeneration of mipmaps).

I disagree. I the case of an IMMUTABLE resource you have to provide initialization data. In any other case you could provide data as long as the resource is not multisampled.

Some of the examples create resources with default usage and initialization data.
