At zooms about caustics test at Path Tracing kernel - OctaneRender vs GIMP
Posted: Mon May 11, 2026 6:14 pm
Hello, guys!
-- ATTENTION: after rendered image, must use EXR (not JPEG nor PNG) image to save from OctaneRender. --
-> because read begin of my clicked message
- Corrects on GIMP - (choose a mirror to download - here)
- Incorrects on OctaneRender standalone - Both apps at 50% zoom
OctaneRender: 50% zoom seems to be correct, if any image has +/-2M or higher spp* at our sun. While if any image has lower than 500k or 1M spp, colors and noises are wrong. At less than 25% zoom has bad antialising.
But on GIMP, any zoom, colors and noises are correct.
* - spp is samples per pixel or px.
Best regards.
