As far as I know, there's no "double render" in VR because, as you mention is expensive. The stereo image is one of the final steps and it does not render a double camera but a double matrix AFAIK, meaning that textures, object light and all that is only rendered once, and the final step is to split and create the two angles for each eye
Hey Sebastián, that is mostly true from what I can tell - some things are only loaded once, but anything that's view dependent is still drawn twice, so even with that optimization it'll unfortunately still have the mentioned limitations.
"blurring things takes resources, so roughness can be expensive to use": no, modern pbr based engines use the mip chain of reflection probes to simulate roughness; rough things are cheaper than shiny things as a result, since they sample at a lower res mip level. (roughness on ssr can be more expensive though, but ssr in VR is a no no as mentioned in the video, and by default most ssr will use a low roughness cutoff and not handle roughness at all, falling back to probe)
i have one and i was not very happy with it. Most games don't work good with it like i already knew before i bought one. And creating for in oculus home also leaves you empty handed because of the limits they have. It's more headache then fun.
Cripple Crash start with the default objects then expand from there, that's what I've been doing when I can have days or weeks of uninteruptions on my pc. That's how I've learning.
5 years later still the ONLY video covering the topic.
and still the ONLY video that is relevant. There's barely any material that covers VR design.
Really good tips -- thanks !
I'm really new to blender and my ultimate project is for VR. This is really helpful as I am still learning the basics.
Normal maps look usually just like a texture map at a closeup shot. Especially on a flat surface. Or do you experience anything else?
Scaling in 3d applications is something developers never learn.
I watched this on vr

thanks man
Thank you
How export to vr. From blender
THIS
What application did you use in the first part of the video
Love this. Great video. Thanks a ton!
I wish I had Oculus Rift.
And a gaming pc.
i have one and i was not very happy with it. Most games don't work good with it like i already knew before i bought one.

thanks for the tips really good vid
can you update features of an asset?
Hi blender cookie I’ve been trying to get into blender and I’ve been wondering where to start?
Awesome, you've found the right place! cgcookie.com/categories/3d/flows
Thanks!

Isn't overdraw a blended alpha problem? If you use hard alphas doesn't the problem go away?
They are used with masked shaders so its ok. It's cheap to render. They don't need translucent shading.
0:33 what addon is that?
Just wondering do u have courses on skillshare or Udemy? :)
Can you tell me which is best laptop for smooth running blender.
MANEESH KUMAR SINGH well it depends on how much you can afford
I appreciate
