There are some errors you can come across while uploading your scene to Spatial.io. As a general rule warnings can be ignored while errors need to be addressed. It may be tricky for new users to diagnose what the issues are.

Error: Package is too large to upload to Spatial #
Issue: Your Unity project is too big to upload to Spatial. This may even happen if your diagnostics says that your scene is within the limit. The cause is usually oversized texture files, even with these images compressed within Unity, the uploader will take into consideration the total Unity project size, which must be <500MB.
Solution: Compress the larger textures, the issues tab will tell you your largest textures in your project. You can either swap, materials or compress the images directly using a compression program like PNG Gauntlet.
- Keep a few worlds max for each Unity project so they don’t become huge projects.
- Compress your textures, and lightmaps and adjust UVs accordingly.
- The more times you are tiling a texture, the larger the bundle, sometimes repetitive tiling can be unsettling on the eyes as much as an overstretched texture.
