To use your custom domain with Shapespark you need to:
- Choose any not yet used sub domain of your main domain.
For example 3d.your-domain.com or vr.your-domain.com (it can't be some already used sub-domain, like www.your-domain.com). It has to be a subdomain. - In the DNS configuration of your main domian add a CNAME record for your chosen subdomain (for example 3d.your-domain.com) and point it to "<your-username>.custom.shapespark.com."
(the trailing dot may be important). - In https://cloud.shapespark.com/#settings enter your subdomain (for example '3d.your-company.com') in the 'Custom domain' input:
DNS changes may need some time to propagate so please be patient, your domain will be activated within hours.
