Answer to the review about Spatial with tips: This product consists on a picture, you can use the 3D models included to apply the vr skies that I made or every other equirectangular sky with the same format because it is a standard (they work fine). If Spatial does not support separated texture files or hdri pictures you need to embed the texture following the documentation of spatial (spatial pipeline's documentation about: importing files or hdri environments). If you are more familiar with Blender, you can do the embedding with Blender changing the default export settings for fbx or glb (check "embed texture" setting in the "export setting" tab). Common tips about blender and relative directories (to read if you move the files in a new directory and then you see a pink material instad of the cool spooky picture): The pink material in blender tells that the texture file is not in the expected directory (that is usually relative). Go to: File > External data > Find missing file (it will find the picture in the folder and replace it automatically in the material that was using the picture). Or edit the material manually changing the texture file with the texture file (in the texture node of the material you need to open the picture that is in your computer). After examination it was found that the product file works fine, this product contains the texture.
