applying HDR makes the meshes black sometimes

Question

Does anybody encountered this problem? when I apply an hdr to a WorldEnvironment, sometimes all the meshes show black when I run the game. see sample 1 and sample 2 .but when I am on the 3d viewport it shows just fine. this only happens on panorama sky, and the problem shows up randomly, so I don't know when it will happen. I tried all the things that I could possibly do, including:

• adding the world enviromnent with the hdr to root node, then removing the default one on project settings
• using a different hdr image
• applying the world environment file to the camera
• keeping the default environment file and making a new one

but it still the same. the only one that works is to reset the world environment, and reapply it again, but its a pain to do it that way. I'm still new to godot and 3d game development in general.
this is the platform im using:
OS: Ubuntu 20.04.4 LTS x86_64
GPU renderer: Mesa Intel(R) HD Graphics 505 (APL 3)
godot version: v3.5-rc6_x11.64
godot renderer: GLES3

Answer 1

You got any lights in your scene? The editor viewport can have a 'preview light' so you'd see things even when you haven't added any lights yet, but that light will not show up in game runtime.

Answer 2

its another problem with directional light though. sometimes the shadow is darker than usual for the player, but no shadows on terrain, as you can see in the image

Answer 3

Surface/mesh self shadowing and cast shadows are 2 different processes. It looks like you don't have shadow casting enabled or it's out of shadow casting bounds perhaps?

Answer 4

sorry, still new to this. where can i find those two?

Answer 5

Mesh self shadowing is just up to the shader/material. Cast shadows are a lamp/light setting.

Answer 6

yep. its all enabled.

I've tried different versions, specifically 3.2.4-rc5, 3.4.4-stable and 3.5-rc6 just to see what it looks like, but still its giving me same result. I might try 4.0 alpha as well

make sure to look through this article in the docs:

Answer 8

I've checked that one as well. So to make sure I didn't accidentally enabled something, I tried to make a new test project with 3.5-rc6. after saved the project,I tried to exit and reopen the game engine to see if the same problem shows up again, and it did.

I then tried the same exact process on different version, (4.0 alpha). I saved the test project, exit and reopen that game engine version, and it works as expected.

Sooooo I could say this could be a bug on version 3?

EDIT:
I guess I gonna need to convert all my work to 4.0 alpha then

Could be, but some of the intel integrated gpu's didn't really have a very good openGL support. So could be your GPU drivers too. 4.0 is Vulkan only for now.
