Trouble with scattering geometry [SOLVED]

[akvahouse]

Good afternoon, I have problem with scattering geometry in Maya, because geometry transforms to low poly. And it does not happen immediately, first render is going well, but after a certain number of times, the geometry is converted into low poly. Can someone tell what's wrong?
Thank you for attention!

Hard to guess what's happening here.
But did you consider rendering from Octane standalone ?
As this is camera animation only, the export process should be pretty straigthforward.

No, I don`t export scene in standalone))
This bug is related to textures, octane cuts them. In library scene all works, but with one object.

right it seems textures are not found for some reason as soon as your object is duplicated.
That's strange because standart instancing in the Maya plugin usually works fine.
What method did you use to scatter the geometry in the Maya scene ?

Maybe I should have look at the sunflower test scene if you can share it privately ?

So you mean that as soon as the object is instanced, alpha textures are wrong ?

Do you have different materials per instance ?

I see your shaders have "pasted" in there name, did you duplicate by copy pasting at some point ?

I used sppaint3d script to scatter geo, and i copy geo with shaders from scene that I created before for shading:
Yes, i can share this scene))

[calus]

Yes, i can share this scene))

ok so let's do this,
a minimal scene with textures showing the problem is best,
you can click on my user name to send a private message,
or share it here, as you prefer.

Standalone don`t help:(

looking into the scene now but the issue is already on the original mesh,
not sure yet if it's a file path problem or lost facesetID ...

oh I think I found the problem isolating one object, seems to be UVset relative.
The problem occure when using an empty UVset, looking more into this.

[calus]

You have 4 UVsets per original object

I think for some reason an empty default uvSet map1 has been added, and is the active uvSet in your scene.

If only DiffuseUVset is supposed to be used, just copy the UVs from DiffuseUVset to map1, for the 2 original objects.

But if depending on the textures the uvSET supposed to be used can be DiffuseUVset or DetailUVlayer, or ExtraInfo
so you should had and a UVprojection node to the imagefile selecting the corresponding uvSet by numbers.
