HD cache accuracy

[maru]

Here's a test of HD cache. Scene looks like this:

[wall with green-purple checker texture] [light facing the wall] [50% white sphere] [50% white wall]

Every time I press F9, the GI calculations look different - there's MUCH more green or MUCH more purple in the bounced light. I know this scene is cruel, but is there any way of fixing this? I tried changing all possible parameters without success. I don't even want to imagine this in an animation scenario.

Last render uses pt+pt.

Can you share the scene? I am new with corona, so I can test this and see what can I try to do.


Sorry for my bad english.

Max 2013. Use camera02 and move somewhere about last frame to have the same view that I rendered.

Set "Position sensivity" to 100 and you will get the minimum variations!

[ikifenix]

Polymax is right. I did few tests and it looks like is the only thing that works.

This is actually a really good stress test scene. It could be used when improving HDcache to minimize flickering in animation. Keep the scene safe until Keymaster returns from vacation ;)

It's safe in here. :) It's also easy to reproduce.

Not really a bug, but the scene can come in handy.
