Thx.
You should see a substantial improvement in AI Light (especially scenes that have a lot of small directional emitters), which is mentioned in the release notes. We have been inching upwards on general render speed, and there are some more experiments currently in progress, but no guarantees can be made right now. We're doing these changes incrementally, otherwise we would be affecting stability, which is our highest priority currently.
I have a scene of a Daz character, with an HDRI background, and 1 emitter, in Standalone.
@1080p with Denoiser for 55 s/px takes 6 seconds on Direct Lighting, no matter if AI lights are on/off.
I toggle all the settings as far as enable, disable, light ID#, Environment, Light ID specified emitter, etc.
Always 6 seconds...
Previous XB3 was, also, 6 seconds.
Now, I am not complaining...At all! I am pleased with this rendering power.
3.08.2 would take 2000+ s/px, over a minute render-time, to match the presentation.
But I am curious if I am missing something...
As far as a 'substantial improvement', say in XB4 vs XB3 - what, if any, with 1 emitter, could I really be expecting here....anything?
I mean, is 55 s/px just too small of a sample range for render time numbers to be decreased, or like, should I indeed be seeing 3, 4, or 5 second render, instead of a 6 second render?
Or, is it just that the number of emitters just isn't a factor here because there is just 1?
As in, if it was a 10 emitter scene, now in XB4 I would then be seeing faster render time than before in XB3, something like that?
Please keep in mind I have no idea what is involved here, I only praise and complain ignorantly.
Thx!
(PS - Also, my interest here is not in a single frame render, it is in the realm of animations. Otherwise, this focus on a couple second gains per image wouldn't be as sought after. )
