NaxosCGCustomerSo i put all that into the “else if Apple USDZdo” ?
Yeap, exactly. Remove all puzzles from there and put this puzzle set.
Works, many thanks.

2022-09-22 at 3:37 pm #56002NaxosCGCustomerSo now i have to find a way to not need UVchannel 2.
Some objects have woods (ch1), and baked AO (ch2).
One solution would be to put all objects with AO into one large 4k AO map, then to use gimp/toshop to prepare each wood map multiplied by AO.
But that will end with many 4k maps… Even if they are loaded on demand, it can be slow.Other solution is to use dynamic AO, but it will not be shown in AR… This could be something that the customer would accept.
Any other ideas ?

ParticipantWhat’s the problems to use the same UV for diffuse colors and baked AO? It makes sense to use the second UV for AO if it’s common for several objects…

If you don’t see the meaning in something it primarily means that you just don’t see it but not the absence of the meaning at all.
2022-09-22 at 4:06 pm #56004NaxosCGCustomerWhat a problems to use the same UV for diffuse colors and baked AO? It makes sense to use the second UV for AO if it’s common for several objects…
Usually, i have one UV channel for, say, wood texture maps, often it is a box UVmap to set size and wood fibers in the right way.
And i use channel 2 for AO, as it needs more accurate UV unwrap, with large parts to get more space, and hidden parts some very small part in the map.The use of that is to be able to change or color / wood / any texture, with AO set for each object. Within Verge3D i just have to change one texture for diffuse color/map and all objects are affected, keeping their own AO maps as a multiplier.
Also, in my Toulet’s billards / foostables i also change AO bitmaps regardless of each ambiance (white studio, hausmannie, and so on : see toulet babyfoot website).
Each billard/foosball table has 5 to 10 differents mesh elements that requires baked AO map, of course i don’t want to bake all color/texture possibilities with each AO, for each mesh, for each billard/foosball…
You might think that i could use the AO-unwrapped UV channel for wood, but that can be a problem because each mesh part / billard has different unwrapped UV map.
That is why 2 channels are really usefull.

2022-09-22 at 4:27 pm #56005Participantfor AO, as it needs more accurate UV unwrap
Take a look at the
scooterorglobal illuminationdemos: one big AO texture for all objects in the scene. In this case the second UV is necessary. But if you bake AO only for one object then there is no need to use more than one UV. One accurate UV.Puzzles and JS coding. Fast and expensive.

2022-09-22 at 4:47 pm #56007NaxosCGCustomerAbout your puzzle to use current choices to export USDZ, there is no “on exit AR” slot, that could help me.
Let me explain :
To prevent the need of channel2 for AO, i can use dynamic AO within verge3D, but it only works with physical materials.
USDZ export doesn’t work with physical materials, so i thought about :enter AR : assign USD materials to objects : export scene
but i need :
exit AR : assign back PHYS materialsThe android part does have an on exit do. is there any way to have one also for iOS ?

2022-09-22 at 4:59 pm #56008Participantthere is no “on exit AR” slot
That’s because you do not enter AR on iOS ))) In fact, you just export visible meshes to .usdz file and download this file. Then AR Quick Look opens this file.

2022-09-22 at 5:07 pm #56009NaxosCGCustomerI get it, but that is a problem so.
I thought to change material, export, then assign back physical materials.
I’ve tried to put the assign back at several places (just after the USDZ export, for ex.), but when i click close the AR, i’m back in verge3D with USD materials, not PHYs ones…"1+1=3... for large values of 1"
2022-09-22 at 5:16 pm #56010ParticipantThe
once fulfilled doslot is a kind of “on exit AR”. The .usdz file is already exported and you can change materials back inside this slot. But there’s one important moment: once you assign a new material to an object its old material will disappear from the scene and you can’t assign it back ))) The workaround is to to have an invisible dummy object in the scene with the same material.Puzzles and JS coding.

https://v3d.net/b14I think that as we are no longer in Verge3D app when in AR mode, the changes are ignored.

2022-09-22 at 5:29 pm #56015NaxosCGCustomerAlso, i’ve tried setting a variable, false at start, then true when material is changed, then a heavy “on each frame”, test if variable is true, then change back material and set it to false…
Does not work.
Also tried to set back shaders with the “when moved camera”…
No way…I’m trying to prevent the refresh / reload of the url to keep user’s choices…

Damn, you’re right ! Thank you for reminding me that.

2022-09-23 at 12:33 pm #56061NaxosCGCustomerAnd now it works well.
Ok, i’ll have to manage 2 sets of materials (one for Verge3D, one for AR UDSZ), but it works."1+1=3... for large values of 1"
