allow animation
Can anybody tell me when it is useful to use the option "allow animation" under "shared for all frames" instead of "time interpolation mode"? Is there any rule of thumb when to use this? Thanks in advance.
Re: allow animation
Only need to read the manual 
Shared for all frames
If only camera is moving in your scene you should select this mode. You should specify a filename that Kray will use to save GI data into. If you don't specify any filename Kray will render into LightWave Image Viewer (only supported in LightWave 9.6+).
There are 3 different modes available:
Load: will load up the Gi data in the specified file. If the GI file doesn't contain enough data to accurately render global illumination it will compute new samples. This mode is often used when testing FG settings since it will only load save data and not save any new one into the file.
Save: will save computed GI data into the specified file when render frame is done.
Update: will load any existing GI data from file and on render end save new GI data into the same file. This mode speeds up rendering of animations dramatically. First frame will take some time to render, but all the consecutive frames will render much faster since they will compute GI only for the part of the scene that hasn't been calculated already. You should be careful with this mode when stopping and restarting rendering of animations. You should always use the same GI file to render complete animation. If you fail to do so you risk having sudden jump of light because every GI computation is a little different. So for example you rendered animation from frame 1-30 with one GI file and then frames 31-60 with another you will see a sudden jump of light in frame 31.
Reset File: Will clear the GI file on your disk so you don't have to go and manualy delete it.
Allow animation: will allow objects to move in the animation. Note however that GI will be computed only for first frame. Other frames will use existing GI. If you want to use full GI solution on animatable items use Time Interpolation mode

Re: allow animation
Thanks for your reply, but I have already read that.
What I wanted to know is when do you use the "allow animation" option and when is it better to use time interpolation mode.
Because "allow animation" will allow animated objects, too, not only camera. I know what the manual tells, but I just wanted some more practical tips.
Thanks.

Re: allow animation
If you need to animate objects the best is time interpolation. This make a recomptation of irradiance on frame numbers you set up.
Allow animation on shared for all frame use the same cached irradiance for all frames i think.

Re: allow animation
If you use Allow animation then your GI will stay the same even though objects move....SaT wrote:Thanks for your reply, but I have already read that.![]()
