HDRenderLoop: Fix issue with cubemap and tile rendering

- I still have issue on both cubemap and light for what appear to be the
last light/cubemap in the list, not sure why.

 uniform int g_iNrVisibLights;
+uniform int _PunctualLightCount;
 uniform uint2 g_viDimensions;
 uniform float4x4 g_mInvScrProjection;
 uniform float4x4 g_mScrProjection;
 	// write lights to global buffers
 	int localOffs=0;
 	int offs = tileIDX.y*nrTilesX + tileIDX.x;
+
+    // This should thow a warning if NR_LIGHT_MODELS change
+    int indicesShift[NR_LIGHT_MODELS] = {0, _PunctualLightCount};
+
 	for(int m=0; m<NR_LIGHT_MODELS; m++)
 	{
 		int nrLightsFinal = ldsModelListCount[ m ];
 		const int nrDWords = ((nrLightsFinalClamped+1)+1)>>1;
 		for(int l=(int) t; l<(int) nrDWords; l += NR_THREADS)
 		{
-			uint uLow = l==0 ? nrLightsFinalClamped : prunedList[2*l-1+localOffs];
-			uint uHigh = prunedList[2*l+0+localOffs];
+			uint uLow = l==0 ? nrLightsFinalClamped : prunedList[2*l-1+localOffs] - indicesShift[m];
+			uint uHigh = prunedList[2*l+0+localOffs] - indicesShift[m];
 
 			g_vLightList[16*offs + l] = (uLow&0xffff) | (uHigh<<16);
 		}
 	}
-
 }
