Aloha Quick Lookers,
I'm using the usdzconvert preview 0.64 to create *.usdz files, which I then edit in ascii *.usda format, and then recipe them as *.usdz.
This way I was able to fix the scale (the original gltf's usually are in m=1, while the usdzconvert 0.64 always sets the result to m=0.01).
Now I was trying to follow the docs
to anchor my Glasses prim on the users face and whatever I try, it will only ever place it on my tables surface.
If I import my *.usdz file into Reality Composer and export it to usdz It does get anchored to the face correctly.
Now when I open the Reality-Composer-Export-usdz it really doesn't look so different from my manually edited usdz (it just wraps the Geometry in another layer, I assume because the import-export through Reality-Composer).
What am I doing wrong?
Here's the Reality Composer generated usda:
#usda 1.0
(
autoPlay = false
customLayerData = {
string creator = "com.apple.RCFoundation Version 1.5 (171.5)"
string identifier = "9AAF5C5D-68AB-4034-8037-9BBE6848D8E5"
}
defaultPrim = "Root"
metersPerUnit = 1
timeCodesPerSecond = 60
upAxis = "Y"
)
def Xform "Root"
{
def Scope "Scenes" (
kind = "sceneLibrary"
)
{
def Xform "Scene" (
customData = {
bool preliminary_collidesWithEnvironment = 0
string sceneName = "Scene"
}
sceneName = "Scene"
)
{
token preliminary:anchoring:type = "face"
quatf xformOp:orient = (0.70710677, 0.70710677, 0, 0)
double3 xformOp:scale = (1, 1, 1)
double3 xformOp:translate = (0, 0, 0)
uniform token[] xformOpOrder = ["xformOp:translate", "xformOp:orient", "xformOp:scale"]
// ...
and here is my own , minimal, usdz with the same face-anchoring-token:
#usda 1.0
(
autoPlay = false
customLayerData = {
string creator = "usdzconvert preview 0.64"
}
defaultPrim = "lupetto_local"
metersPerUnit = 1
timeCodesPerSecond = 60
upAxis = "Y"
)
def Xform "lupetto_local" (
assetInfo = {
string name = "lupetto_local"
}
kind = "component"
)
{
def Scope "Geom"
{
def Xform "Glasses"
{
token preliminary:anchoring:type = "face"
double3 xformOp:translate = (0, 0.01799999736249447, 0.04600000008940697)
uniform token[] xformOpOrder = ["xformOp:translate"]
// ...
I'd add the full files, but they are 2Mb of size and the max file size is 200kb. I could create a minimal example file with less geometry in case the above code is not enough.
