Hi All,
I haven't found a fast and consistent workflow to render animations with moving objects.
There are those 2 tutorial on spot 3D about this topic.
The 1st one involves compositing and makes sense but requires a lot of extra work that I can't always afford.
The second and most recent one is faster and includes prepass and rendering with camera path option on both LC and IrrMap.
I have tried this few times and got random results.
Sometimes it works, sometimes it doesn't.
I might have done some mistakes along the way and got some stable and splotchy, but not flickering, GI.
Anyway, rendering a Light Cache and a Medium Preset Irr Map per every single frame raise my rendertimes to 30 min each.
Here I am to ask what is the best and fastest way to render moving objects. I will be grateful if you just post the link to a previous thread about it.
In the meanwhile I have developed a workflow that makes sense in theory but wasn't able to make it work yet.
I am pretty sure it is a technique used in the film industry so someone might have some good tips.
The idea is again to render in 2 passes. In the first one I exclude all the moving objects from the scene and render a normal flythrough animation.
The second is to create a hdr image of the scene to light the moving objects and render them separately with an alpha and then comping it.
The result won't be 100% perfect but I am pretty sure I will get a closer lighting and a much faster rendering without loading the entire scene.
Has anyone tried this?
I remember I have tried it once and having problem to find the right camera to use. Probably the box or fisheye are the correct ones.
As well I was having such a big difference in terms of exposure and lighting. Any suggestions?
Kind Regards,
Giacomo.
