Help - Rendering a Camera Walkthrough.....

[ripe]

I've rendered walkthrough's many times - and I usually turn to the online help to remind me of the workflow each time - but i'm now confused!!
Read a lot of old / various threads - that just confused me more

https://docs.chaosgroup.com/display/...ough+Animation

What I normally do is

1_set both primary and secondary GI to Lightcache - then renders a 'flythough' lightcache and save it.
2_set the primary GI to Irr Map and the secondary to the saved lightcache
3_render a multiframe incremental irr map (every 10th frame usually)(and save it)

4_I then have a saved irr map and a saved lightcache file

5_I then set primary GI to the saved irr map and secondary GI to the save lightcache map - and render my actual frames of animation.

So - i'm using both files when I render - the online help does not mention a lot of this - but i'm sure it once did - hence why i'm confused?

Am I doing this right? Does the irr map contain the light cache data when it's made after the lightcache calc and save? If so - what do I set a primary and secondary GI?

I'll add my vote for the above request also, as it seems many original tutorials online aren't keeping up with the new changes & settings available in today's version. We don't do a lot of animation work, and I really dread it when we are eventually asked to because the information available for the re-learn process seems fragmented and contradictory at times. There are alot of steps and mouse clicks involved in properly setting up the pre-calc process, followed by the post-calc process and if any step or setting in between is missed or incorrect, we can throw hours of productivity out the window. Thanks all!

I think the simplest way is:
1. Set GI primary to Irr map, check 'use camera path', check 'Auto save' and add a save path.
2. Set GI secondary to lightcache, check 'use camera path', check 'Auto save' and add a save path. (I think you only need this step if you have 'Use for glossy rays' checked in lightcache)
3. Check 'Don't render final image' and render. (at this point I would save the VRay tab as a render preset)
4. Set both primary and secondary to 'From file' and point them at the files saved from (3).
5. Uncheck 'Don't render final image' and render. (again at this point I would save the VRay tab as a render preset)
6. Render your animation.

If you get a lot of flickering, use Brute force as a primary engine. I had t do that for an interior animation. For exterior ones is easier to get a better quality in general.

Hi all.

I tried my 'normal' method as my 1st post and results were generally ok.
- this is use light cache for primary and secondary as 'fly through' - then save light cache map.
- then set primary to irradiance map and secondary to saved light cache - use multi frame incremental (every 10th frame) - then save irr map.

Use both files for rendering.

I also tried rendering both at once in one hit using single frame and the camera path option in irradiance map - but as its only rendering 1 frame it calculated the irr map far too quickly - so I'm sure this is wrong? As light cache is set to fly through - this appeared to render fine. I just don't see how the entire irr map is generated with this method?

I tried the files for rendering and the GI was really soft with little detail?

The irradiance map also has a "use camera path" option that you can use in this case, but it only works for very short camera moves. For anything longer, you'll need to do the every Nth frame multiframe incremental mode.

Thanks for the feedback. It's true that some of the tutorials are outdated and they do not follows the changes and updates in the latest versions of the software.
This is something we we are working on and it will be improved for the near future.
