The normal map was baked out from a .SBSAR in the Slate Material Editor and I think a gamma curve is being applied internally during that operation(?) I've been talking to the integrations team about it to get some clarification.

I think gamma was applied during saving. Depending on how you were saving, you either have to do it with default gamma, or with gamma override - 3ds max is very inconsistent here. And to add to confusion, if you save to PNG, max saves its thumbnail with wrong gamma.

Nice, but 7 hours for that small resolution? Ouch! Is it slow CPU, or complexity of the scene/material?

I let it run overnight, so I'm not sure at what point the image converged at an acceptable noise ratio (~3%), but it's true the image is rendering slow (Threadripper 2950x, 64Gb RAM).

- hair is probably using a more complex material than it needs to
- plaid is using a more complex material than it needs to
- could probably run a rayswitch on the chair metal to speed up the GI calculation

Really my issue is with the blanket, which I think is using an SSS + displacement + opacity; probably overdoing it and just need to balance the falloff in the diffuse channel. Right now the plaid material looks like gauze or a sponge or something :/

Yeah I tried using similar killer combo once.. It's like 100x render time multiplier. I was trying that 'invisible surface/volumetric inside' trick.

lol yeah that's exactly what I was trying to do and it just hasn't really worked as expected.

Trying something different with basically just vol. scattering and it seems to be working better.

Exactly. Both my client and Veronika told me the result looked like alien crap and instead switched to full-scale geometry scattering (of fibers inside volume).
Which produced billion polies, render-multiplier still something like 5x at least but looked good.

TyFlow or Forest Pack for scattering, j/c?

Thanks Bormax, obviously credit to Friendly Shade for the model and texture set.

I had a harder time creating a shader to represent the cozy / fuzzy / fabric feeling of a chunky knit sweater than I expected, but I feel like this comes close.

The sweater is awesome. I'm also working with clothing renders and have just subscribed to Ornatrix. Any tips for a newby on how to go and create such a fine woolly cloth?

Hair / Fur with Ornatrix is super easy, but remember that hair / fur is scale dependent so be cognizant of the Xform of the object being groomed etc.

Ornatrix and hair / fur grooming, in general, requires some experimentation to get the right look for the asset. I've attached the groom for the sweater here (see attached).
