Custom room and content guidelines

Follow these guidelines when creating environments you wish to use as custom rooms to SynergyXR

Best practices:

Keep surfaces as flat as possible (walls, floor and ceiling).
Walls, floor, ceiling and other surfaces need colliders. Use box colliders where possible.
If there is a built-on skybox, its radius must be less than 600 meters and preferably more than 4 times the size of the room.
If possible, use non directional lightmaps to improve performance
Use a uniform and simple lighting setup
Avoid spaces less than 2 meters in any dimension
Sprite renderer is not supported, use render texture or textured quad instead.

Technical recommendations:

Keep 3d model under 100.000 tris, and always as low as possible with acceptable result.
Consider the combined number of polygons and textures for room and content if you want to fit a lot of content into a room.
Be selective with large texture usage. One texture used multiple times counts as just 1.
(Only in rooms, not for content)
Do not duplicate materials, if you could instead use the same material again. Multiple usage of the same material still counts as just 1 material. (Only in rooms, not for content)
The fewer textures a material is using, the less impact on performance.
Keep textures as low as possible; resolution 72dpi with pixel width and height in a power of two (...32, 64, 256, 512, 1024, 2048...). File size also matters, so compress tour textures using e.g. .jpeg compression.
Maximum 2048x2048px, preferably 1024, 512 or even less when sensible.
Every single texture (Albedo map, metallic/smoothness map, normal map, Occlusion map etc.) used in a material counts as another texture - keep total amount of textures minimal.
Use baked lighting only.

Examples based on purpose:

Example #1: Content is focus (Auditorium):

Example #2: Content and room is of equal importance (Exhibition):

Example #3: Room is focus (Tutorial Room):
