I have a solution to the shadow flickering which we will release with Terragen 2.4 with Animation. .... There is still the second problem of shadows cast from terrain behind outside the camera view .... We'll also provide a solution to that in v2.4.
Hi Matt,
this is very good to hear and absolutely neccessary to get high quality animations. During the last weeks I played around with differend parameter values (and I got a faster computer... ;-) so the processing time for good quality animation frame is down to 8 minutes now.
There are still some errors in the animation. Two error sources are hopefully gone with TG 2.4, for a solution of the third I hope on the expertise of you and the forum.
- there are still receding shadows as you approach them. Other than in my previous animation this time the sun is at a 90° to the camera look angle (and the flight path). The camera is looking towards north and the sun is 10° over the horizon directly in the east. See attached subsets of image 855 and 856.
- The shadow flickering is quite annoying, although I increased the GI values. I really hope for TG 2.4.
See attached subsets of images 1142 and 1143.
- From time to time it looks like the indirect illumination of the atmosphere is switched of. Then after some images, the normal illumination comes back. Do you know about this bug? Do you have any idea how to deal with that? See attached subsets of the images 1537 and 1538.
The parameter values I use now (tgd-file attached):
Quality:
Detail = 1
Anti-Aliasing = 4
Ray trace objects
Ray trace atmosphere
GI relative detail = 2
GI sample quality = 2
GI blur radius = 200
Supersample prepass
Extra:
Pixel filter: Narrow cubic
Anti-aliasing bloom
Detail blending = 3
Displacement filter = 0
Microvertex jittering
(Detail jittering off)
(Lock subdiv to frame off)
Do ray traced shadows
Ray trace everything
Advanced:
Ray detail region: Detail in camera
Ray detail region padding = 3
GI prepass padding = 0
By the way: the forum editor is horrible. I had to type blind because while typing the visible window sticks to the uppermost text. And when sending the post there came the error message that tif-images are not allowed and all my text was lost. So now I type everything again in my own editor and copy it into the forum...
Kind regards,
