Hello,
Sorry for the necro, but I just wanted to throw a link to This thread incase anyone is searching for “VR Template Bloom”
From this post it’s not clear if you’re deploying to PCVR or Mobile VR.
In the context of Mobile VR (Oculus Quest) Bloom is a postprocess effect and requires Mobile HDR to be enabled. (It is best practice to not use Mobile HDR in mobile development because of the performance impact)
