Hello Community, I use Unity 2020.2.xx, somehow it seems a bit strange to me that when I import 1GB textures package it takes several hours. Is that normal or can I somehow reduce it. 2 days ago I started a new project. There a package with 2.9 GB (FBX + textures) imported (import took 3 1/2 hours) then I wanted to install proBuilder and Unity imported the same package (textures) again (again 3 1/2 hours). Now I’ve finished part of my scene and I was still missing a few textures. I wanted to import about 1.9 GB and Unity has been importing for about 4 hours. Why is that.
My system: Windows 10 + Intenso SSD 1TB + Ryzen 9 3900x + 64 GBRam + RX5700xt
I’d say it depends on what platform you are building for and what compression Unity is using for it.
For example.
If I import 1 gig of textures into PC project lets just say for example it takes 1 hour (just an example). However if I import the same said textures into a Quest 2 project with ASTC compression it’ll take waaaaaaaay longer, like 6 hours longer, because of the default block sizes.
But then the next part of the question is, are the 1.9 Gig textures bigger sizes? That can also account for the time discrepancy.
But when I build for PC, import times don’t generally take very long at all. So if you’re doing PC stuff, I’m afraid I can’t help, the only thing I can say is to check the type of compression Unity is using. Default PC compression shouldn’t take long to import anything. Of course if you’re doing 16K textures that’ll take a few moments regardless of platform lol.
If a texture needs to be compressed, that’s going to eat up a lot of time, and different compression types take different amounts of time. I usually have specific folders per import setting and use Presets.
Thanks N1warhead, it is indeed a Quest 1/2 Project. Ok that explains some of it is HD textures. I know that they lead to frame break-ins in full resolution, so I’ll edit them later. Thanks for the quick answer then I plan to import about 5 days.
Keep in kind, even a 256 x 256 with ASTC compression will take a bit of time compared to a PC Project. ASTC is just slow as molasses, however - it does give a good compression ratio so that’s the pro of it.
For example (just another example). A 1.5 Meg texture for PC is now suddenly 30KB in size and still looks somewhat decent. (not great), but a close approximation to what the raw data is supposed to look like.
