Hey, Does anyone know if Mac OS X Version 10.6.8 3.06 GHz Intel Core 2 Duo is able to enable shadows and lighting? I want to take some pictures with shadows using Second Life Viewer 3.0. Edit: I don't have an external graphics card. Just what came with my Mac computer. The Mac itself comes with : NVIDIA GeForce 9400: Chipset Model: NVIDIA GeForce 9400 Type: GPU Bus: PCI VRAM (Total): 256 MB Vendor: NVIDIA (0x10de) Device ID: 0x0869 Revision ID: 0x00b1 ROM Revision: 3454 Displays: iMac: Resolution: 1920 x 1080 Pixel Depth: 32-Bit Color (ARGB8888) Main Display: Yes Mirror: Off Online: Yes Built-In: Yes Display Connector: Status: No Display Connected I am able to apply Lighting and Shadows, Atmospheric Shaders, Ambient Occlusion and Depth of Field when my Quality and speed is at Ultra. Then I go to the Develop Menu- Rendering and check SSAO and Shadow Smoothing. Though I cant seem to see shadows when I walk, or behind objects. Is this the proper way to ebale Lighting and Shadows? Thank you! Lynzzy Neox
