Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

SunLight flow through grounds at night hours.

Hello everyone. My question is about Sun Lights.

Is there a reason why SunLight flow through ground? I am using SunPositioner plugin in 4.21 and selected time is 00:00. Lat & Lon values aren't important here because sun light is coming from somewhere under a simple static plane mesh. (Set to 0,0 if you want to test it) And light comes from many angle to car. It's like there's no mesh between bottom of the car and static plane mesh.

Note: Even if I don't use SunPositioner plugin, result is same.

Lighting quality: production

Material Blend Mode of surface is Opaque.

I don't know anything about this plugin, but when I was doing my night/day system, I just set intensity of directional light to zero at desired hour. Also, is material assigned to plane mesh double sided?

Yes, double sided material. I have suspects on SkySphere is reflecting light where it shouldn't.

When I moved car 20 units up on Z axis, problem solved. But If I move PlaneMesh and Car 20 units up together, problem continues.

So, there should be at least 20 units diffrence in Z axis between Car and PlaneMesh to solve the problem but that means Car would be like hovered, lol.
