Hi,
thanks for the new build.

I've tried new displacement and there are few issues:
- there is no old texture displacement
- viewport performance very bad eg. a mesh with displacement renders with 3 fps and without 40fps
- rendering performance is 4 times slower with displacement enabled
- when ...

Hello. Can you find the issue at the daylight env.?

New rendered images:
different caustics for camera moving despite fixed light source.png
--When the camera is moving--:
-On Photon Tracing, caustics aren't changing due to MISSED "variable" caustics;
-On Path Tracing, caustics are changing despite fixed light source.

Happy Rendering ...

Hello. :)

This is easier and better understand about the variable caustics. :)

Hello, guys! :)

VERY IMPORTANT for avoid any confusion due to weak precision of noises+colors of JPEG or of PNG image type:
-after completed rendering, should choose "EXR" image type with uncompressed, and with FP32 for insane color depth (this competes perfect true color at in the real life ...

Hello, guys. :)

Can you remember oldest "Octane Render" benchmark (April 2010 :lol: ) - here ? :)

But this original "Wall" scene is edited (changed material from "glossy" to "specular") by me in 2014. ;)
