rendering animation where a lot of stuff is fading in (animated using graph editor) …various objects…
rendering methid used is IRR map for primary and light cache for secondary.
now…what we get is ridiculous speeds for lightcache calculation where objects are fading in and out…10 HOURS and more !!!
Is this rendering method suitable for this animation type or not?..if not …what is the most suitable method for doing this?..we have loads of moving objects, stuff fading in and out…want clean solution…no flickering
can u please help us as the deadline is approaching and we only found out today :shock:
As far as I know there isn’t a quick way to do fading objects directly out of VRay. It’s far quicker to to render one sequence of frames with the object fully visible and then one qith the object hidden and fade btween them in post. From my experience anyway…
No, you can still do the same thing… render the segment where the object fades twice. Once with the object on, once with it off, then blend in post… it will render much faster.
Even scanline is slow when it comes to object visibility, and the reason is because the renderer calculates the object twice, and then blends the results based off of the % of visibility.
Now, if anything in your scene besides the camera is animated, you don’t want to be using IRRmap… to avoid flickering you’ll have to set the settings so high that your rendertimes will be unusable.
