Ohh I see, I was worried about the method used to average the samples, but was ignoring the precision and color depth, that definitively has a higher impact!

Yep!, I'm interested on processing the images with 1x1 pixel samples, so they don't blend against any background, but I don't have problems rendering to my current target resolution (512x512, with 3x3 sampling goes to a 1536x1536 output).

I just wondered if I could still use the options Houdini offers for pixel filtering after I'm done in the external processing tool. What I do using GIMP is taking the 3x output image, applying a gaussian blur (3,3) and downscaling to my target 512x512. I'm not sure if this is similar to what Houdini does internally, and also don't know if sample randomization should have any effect on this.

But that's very useful info! I may need to render those 9 plates when I get to test higher resolutions.

Hi!

I'm using Houdini FX Apprentice HD for a college project where I need the sub-pixel output to process it in a external tool, using 3x3 samples per pixel this creates an image with 3x the original size.

After my process, I need to create an image again with the original dimensions; I'm currently doing this by downscaling using GIMP but… I wonder if there is a method in Houdini to receive back the subpixel output and finish the image using the built-in image resolver. Is it possible?

Btw, Houdini is awesome
