I found the shadow settings in the Parameter Dials, silly me :dash: . [color=blue]I applied your suggestions as follows, saving and rendering to check[/color] if the black artifacts disappear after each step 3, 4, 5 and 7 : [b]Step 1[/b]: [i]Restart Poser 4 Pro to Default Factory setting[/i] [b]Step 2[/b]: [i]Load base Posette, set pose & set camera[/i] [b]Step 3[/b]: [i]Change all 3 the Default Lights to Shadow = 0.8 and Map Size = 1024[/i] [b]Step 4[/b]: [i]Add a 4th back spot light to compensate[/i] [b]Step 5[/b]: [i]Reduce screen resolution to 1024x768[/i] The [color=red]problem persisted in Poser 4 Pro[/color] after those settings. [b]Step 6[/b]: [i]Return screen resolution to 1600x900[/i] [b]Step 7[/b]: [i]Open and render the file in [color=red]Poser 6[/color] using its own [color=red]native Poser 4 Render setting[/color][/i] [color=darkgreen]There are zero black artifacts in this render[/color]. [color=blue]Something I forgot to note is, when Poser 4 Pro starts up and runs on this laptop computer with Windows 10 64-bit, edges of the sceen flicker, even while busy with the application[/color]. That flickering doesn't occur when starting and running Poser 6 on this same computer. [i]Because of this[/i], [color=blue]I'm going to conclude[/color] :einstein: , up to this point, that the black artifacts which occur during rendering in Poser 4 Pro on this computer are a [color=blue]result of a slight incompatibility between Poser 4 Pro and this hardware or this operating system[/color]. I think, while I'm learning :pottytrain4: the details of Poser 3 and 4 on this computer (and hopefully Python scripting), I'll try to [color=blue]avoid the appearance of the artifacts with alternative camera angles and zooms[/color], which increase or decrease their visibility. Also, if I do any artistic renders on this computer, I'll [color=blue]rather render them in Poser 6 with its own native Poser 4 render setting[/color], to avoid producing those artifacts. :thumb: I am grateful for your kind assistance in attempting to resolve this issue :thumbleft: . Thank you kindly! May you be blessed. [i](P.S. It's amazing how much different the Poser 6 render looks from the Poser 4 Pro render in terms of lighting. Even though Poser 6 tries to simulate the Poser 4 Pro render with Poser 6's own Poser 4 render setting. The Poser 4 Pro lights in Poser 4 Pro give a 'more red' tone to the skin... while the same scene opened in Poser 6, with no changes to the light settings, give a 'more neutral' tone to the skin. Also, the highlights appear differently. I don't understand why that is :dontknow: , or the technicalities behind programming lighting into an application, but it requires us to change lighting when we move from one Poser version to another.)[/i] [img]http://www.posetteforever.com/files/posted_images/6747/_ps4_black_spot_investigation_05___summary.jpg[/img]
