View Full Version : IR + QMC HDRI render with Liquids

Hey guys,

So since its the holiday season...I decided to do crazy renders before leaving the house for food and family and all that and just let the computer work through the holiday.

So I had this project where a phone crashed through a wall of liquid sending the liquid everywhere. Instead of introducing any lights in the scene, I decided to just let this thing run.

I used IR + QMC with a blurred HDRI map. But what is interesting is there is major color flickering though subtle. Is IR + QMC (full animation) not as effective as I thought it was? I thought it might be something I could use if I had rendering power or time on my side and would avoid any flickering.

Also, do you export your Irradiance Cache somewhere by picking a location cause in the mid of rendering the computer screamed that it did not have enough memory - try using a 64bit cinema4d but I am using 64bit and the render went ahead anyway.

Odd. =)

Anyway Merry Xmas and happy new year!

IR+QMC Should be fine, but are you running either an older version of net renderer to render or do you have GI caustics enabled? If not then can you share the scene or even a simplified version that shows the problem?

Without seeing the file it's hard to know what exactly could be causing flickering, it could just be that the shadows cast by your many small droplets/objects appear as flicker, which it probably would with normal lights and shadows too (though if not you should make use of per pixel sampling for GI emitters and portals). Or caustic effects, which in general look like flickering anyway. Or it could be a bug in GI... or any other number of other things.
