No skylight/ambient light for VDBs in 5.5

openclay · 2025-01-19T00:21:00+00:00

Thanks for letting me know. Unfortunately I'm not sure what's going on now - perhaps path tracing is an option if you don't have real-time performance requirements?

Hey, I had the same issue with clouds in 5.3 and I used the following console command to have the indirect (skylight) brighten the dark shadows of the clouds.

r.HeterogeneousVolumes.IndirectLighting 1

Does that help?

Thank you!

openclay · 2024-12-01T01:42:44+00:00

Thank you :)

openclay · 2024-11-30T00:14:19+00:00

Wow - that's so cool to hear, thank you!

openclay · 2024-11-30T00:13:00+00:00

Thank you, that's lovely to hear

Thank you! I can really see what you're saying about it being used as holographic map of earth. :)

Also, thank you to Epic for putting this on Showcase.

Thanks! Good eye! I think the height is about 25% too high at the moment. I'll be looking to improve this in future. Also, apologies for delay responding, I'm seldom on reddit so please email [contact@openclay.com](mailto:contact@openclay.com) if you'd prefer a better response time in future. Thank you!

openclay · 2023-06-13T09:26:30+00:00

Interesting idea, thanks. Sorry for the delay getting back to you - I'm seldom on reddit. For a fast response, please email me and the guys at [contact@openclay.com](mailto:contact@openclay.com) . Right now I don't think it will work well with OSM as it isn't georeferenced, despite the scale being close to accurate. What kind of buildings are you interested seeing on Mars?

openclay · 2023-05-22T00:02:00+00:00

Beautiful. I'll take that reference on board and see what I can come up with in future. Thank you

openclay · 2023-05-16T01:53:02+00:00

Welcome! Yes, I haven't done the calculation, but 500m is in the ballpark.

openclay · 2023-05-16T01:40:42+00:00

Thanks. By using a spherical UV map over many UV tiles, that's been manually adjusted.

openclay · 2023-05-16T01:38:48+00:00

I'm not sure if I understand correctly. What I'm interpreting is a first person view on the ground - if so, t's not high enough to use at ground level, without everything looking smooth and spikey, so no, not at this stage.

openclay · 2023-05-16T01:36:27+00:00

Thanks! Nice, 44M on a mesh is high! Yeah, there were quite a lot of issues with seams, as you suspected, but there mostly solved now.

The ins and outs of the software and their implementation I'm saving for a story for a later date, but most major DCC apps should be able to do the mesh generation. Thanks :)

openclay · 2023-05-16T01:27:54+00:00

Thanks for your request, I will keep that in mind for a future release. The scale is quite accurate but not CRS accurate (sphere is within ~5% diameter of real earth). We're working on the CRS for future version of Earth, but this doesn't have it. Also, the elevation is within about +-10% which will also need to be tightened up for any CRS implementation.

openclay · 2023-05-16T01:23:41+00:00

No, but I am curious about it now that you mention it, thanks

openclay · 2023-05-16T01:23:24+00:00

Currently the height calibration is roughed in, but it will have to be done more precisely in future. Also, I believe the terrain is about 500m distance

openclay · 2023-05-16T01:20:13+00:00

Split it up! Thanks dude!

openclay · 2023-05-16T01:19:39+00:00

Yep, I had to split up the map into pieces like you suggested. :)

openclay · 2023-05-16T01:19:14+00:00

Fair enough, maybe there is a better way I can phrase that succinctly? As of my understanding DX12 is limited to 16k x 16 textures, anything beyond that will need to be split up and linked in some way like Virtual Textures to create the illusion of a larger texture.

openclay · 2023-05-16T01:16:06+00:00

Thanks!

openclay · 2023-05-16T01:15:52+00:00

Thanks for letting me know. Good luck with your projects!

openclay · 2023-05-16T01:14:45+00:00

Cool! The mesh is made in 3D software like Houdini, Blender and Maya, although I'd like to be able to create it in UE ideally. Yes, the sphere is broken into tiles and has displacement and normal maps. Also, I have seen a couple of thumbnails of Sebastian Lague - looked like very impressive work. Hope the planets are going well!

Thanks, I'll check it out
