So I posted this on the forums initially, but I’m posting here due to the relative lack of interest there as well as my realization it may not have been the best location to post.
I need to get DFGI working in a project I’m doing, and I understand it’s limitations… I’m not doing anything speial that should be breaking it, but instead this seems to be related to user error.
Essentially, enabling DFGI via console variables does absolutely nothing (except for terrain heightfield GI which works fine).
DFGI Alone fails to work properly, and emissive lights have no effect (though, I was made to understand emissive lighting is not a feature compatible with DFGI which is fine).
The directional light produces strange and improperly distributed spots of light near the general area of the light bounce, but they are obviously not he intended result.
Here’s an image of the strange behavior (which I assumed was linked to LightPropagationVolume settings, but post process volume LPV settings had no effect {enabled and unlocked the volume}).
DFAO works fine as do distance fields (enabled and visualize properly), but DFGI does not seem to be occurring.
I should also note, the same occurred to a fresh test scene from a newly installed 4.14.0 version, and I got the exact same results (an obvious pointer to user error), so, in order to perhaps simplify the process, could someone provide step-by-step instructions for getting basic DFGI results from scratch, just in a test scene. That’d be great!
I should also note, the spotty points of light on the wall bled through meshes, which is supposedly not characteristic at all of DFGI, but rather of LPV. Furthermore, their intensity is affected by indirect lighting strength not of the skylight but of the directional light.
I should also note, I have set them to movable, and made sure I followed the step-by-step process outlined in several forums, so this is especially strange (ESPECIALLY with the 4.14.0 tes scene, as this clearly points to user error, and I’m pretty sure I did everything correctly).
ANY and ALL help is welcomed and readily appreciated.
Thank you!
Also, I can provide more information if required. On another note, saving a project with DFGI, at least in 4.13.2, was the cause of a strange crash. Disabling DFGI fixed it. Not sure if this is related, but I can certainly reproduce the bug if anybody wants to mess with the project file. On one FINAL note, I am on a relatively limited time-plan, and need to have a project (hopefully and almost necessarily involving DFGI) done in 2.5 weeks, so a general sense of urgency is always appreciated
Thanks again!.
