PIXELIZATION

Posted by Christopher Alan Krupp on September 22, 2011 at 7:18am in IRender nXt ArielVision 3D Design Studio (Sket

Hey guys,

I am attaching a rendering that has 5250 passes. Yikes!

Anyway, note the pixeliztion of several of the areas in the rendering. It's quite large. The areas are set up as a highly reflective material (sketchup metal)

 

What can I do to get rid of this? I've run this rendering numerous times and it's there every time.

    Al:

    Thanks for your input. I think your were right on all counts.

    I think the pixelation is coming from reflections from the low-res HDRi sky.

     

    Here I turned the sky back on and you can see that the sky is pixellated a lot like the sculpture.

    You may need to make the sculpture less reflective, make it glossy, or make the reflection less sharp.

    Here I change the sharpness from  1.00 to 0.50 and it seems to remove the pixelation from the reflection.

    Here's what you asked for..............I made a copy of the original and left everything else the same.
    I did notice something odd with the model though...............it's upside down...........the blue(-) axes is running toward the top...........hummmmm?
    Don't know how I got it that way, but it is. This a practice model from a LONG time ago.
    Didn't notice the invert until I removed everything else.
    Never the less, an interesting issue.

    Your rendering has what one I tried on just the sculpture though.....that black stripe across the object. What's that about?

    Are we looking at this area here:

    2506647316?profile=originalIs the triangular area a single, flat material, or is it composed of small rectangles, or a texture which may be repeating.

    If you are looking at just the pointed area, try copying and pasting just that geometry into a new .SKP file and sending it to use at support@renderplus.com so we can try rendering it.
