I downloaded several freebie FBX figures from Mixamo, selecting T-Pose and Classic 'FBX 6.1' format.

Imported at default 100% scale as a single rig, but a jumbled mess. 'Zero Figure' resolved.

Click on a body-part, twirl pose-dial, Yay !! Note Poser 'symmetry' tool does not seem to apply...

Local superfly test-render went okay, I sent a bigger, better, brighter job to my networked 'Box'. LaF's textures etc transferred okay, but the FBX figures' did not. Queue-manager (both 11.3.740) reported, 'could not send file', left imports untextured.

I  told Poser to reload textures, re-rendered. No difference.

I closed, re-opened Box' remote-render app, re-rendered. No difference...

I closed and re-opened Poser, re-loaded saved PZ3 scene, re-rendered. No difference...

Ideas ??

Ah...

It may be an obscure 'pathing' problem, as 'FBX Review' auto-loads the textures, but Paint 3D cannot...

Added: I tried exporting figure from Poser as FBX. This time, Paint 3D prompted to navigate to texture folder, loaded the set. But, when I imported figure, I got same 'local okay, remote untextured'...

Of course, there's a zoo of export parameters, I may have picked wrong mix...

"No, I'm not imagining it-- I swear I saw a cute blonde running around bare-foot in a black swimsuit..."

It's not just FBX. I converted an SFM model to OBJ+MTL, but the big prop did not show textures when remote rendered.

No error message, just did not transfer texture files.

Even more puzzling, works okay using a Poser primitive...

Lest due 'super-ambiance' of truck lights, I set the jello-cone a-glow, too...

These test-renders are local on CPU, local on twin GPUs, 'Network render' (CPU) on 'Box'...

Superfly, 14 pixel-samples, progressive, 64 bounces & buckets for CPU use, 1024 for GPUs.

Perhaps related, I've had a pair of FBX imports suddenly lose their textures to 'all black' in preview, but render okay, local or remote. I tried a bunch of stuff without success. Eventually saved scene as PZ3, closed Poser, grumbled, reloaded, and preview now okay...
