|
|
|
|
Generates the VRS texture based on a render ``target_size`` adjusted by our VRS tile size. For each eyes focal point passed in ``eye_foci`` a layer is created. Focal point should be in NDC.
|
|
|
|
The result will be cached, requesting a VRS texture with unchanged parameters and settings will return the cached RID.
