Hi Ok, this is driving me nuts for weeks now. I've read every lighting-thread on gamedev.net about a hundred times now, but still can't get my (point-) light to work. One reason might be that I don't understand the DX lighting system :D Ok, here we go (just in case you're curios, "gState" is my statemanager so I don't get any "redundant render state" warnings): gState.SetRenderState(D3DRS_LIGHTING, TRUE); // eh...yeah :) Here's my light: D3DLIGHT9 lfFlashlight; ZeroMemory(&ltFlashlight, sizeof(ltFlashlight)); D3DXVECTOR3 vecLight(playerPosition.pos); vecLight.z += 2.0f; ltFlashlight.Type = D3DLIGHT_POINT; ltFlashlight.Diffuse.r = ltFlashlight.Ambient.r = 0.0f; ltFlashlight.Diffuse.g = ltFlashlight.Ambient.g = 0.0f; ltFlashlight.Diffuse.b = ltFlashlight.Ambient.b = 1.0f; ltFlashlight.Diffuse.a = ltFlashlight.Ambient.a = 0.0f; ltFlashlight.Range = 100.0f; ltFlashlight.Position = vecLight; ltFlashlight.Attenuation0 = 0.0f; ltFlashlight.Attenuation1 = 1.0f; ltFlashlight.Attenuation2 = 0.0f; hRes = pD3DDevice->SetLight(0, &ltFlashlight); // S_OK hRes = pD3DDevice->LightEnable(0, TRUE); // S_OK These are the texture states I set before rendering my level (BSP): gState.SetTextureStageState(0, D3DTSS_COLOROP, D3DTOP_SELECTARG1); gState.SetTextureStageState(0, D3DTSS_COLORARG1, D3DTA_TEXTURE); gState.SetTextureStageState(0, D3DTSS_COLORARG2, D3DTA_DIFFUSE); gState.SetTextureStageState(1, D3DTSS_COLOROP, D3DTOP_MODULATE); gState.SetTextureStageState(1, D3DTSS_COLORARG1, D3DTA_TEXTURE); gState.SetTextureStageState(1, D3DTSS_COLORARG2, D3DTA_CURRENT); This is blending the level texture with a lightmap - works fine without lighting. My vertex struct: struct VERTEX { D3DXVECTOR3 pos; TEXCOORDS surface; TEXCOORDS lightmap; D3DXVECTOR3 normal; byte color[4]; }; Vertex declaration... const D3DVERTEXELEMENT9 vertexDeclaration[] = { { 0, 0, D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_POSITION, 0 }, { 0, 12, D3DDECLTYPE_FLOAT2, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 0 }, { 0, 20, D3DDECLTYPE_FLOAT2, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_TEXCOORD, 1 }, { 0, 28, D3DDECLTYPE_FLOAT3, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_NORMAL, 0 }, { 0, 40, D3DDECLTYPE_D3DCOLOR, D3DDECLMETHOD_DEFAULT, D3DDECLUSAGE_COLOR, 0 }, D3DDECL_END() }; I draw the normals and they are correct, they're normalized. So, why isn't my light working? :( thanks in advance
