Hi, I'm new in Blender and Octane. I just downloaded a cotton texture from Poliigon and I converted it to a Cycles material using their tool, everything works fine so far.
I cannot convert it to an Octane Blender material, can you help me? I attach the blender file and textures.

See attached zip for Octane converted.

I’m not too familiar with Cycles nodes so that set up you had was interesting to me, though the Cloth Falloff didn’t seem to be affecting anything that I could tell.

For conversion of Specular/Gloss to Metal/Roughness I inverted the Gloss map and hooked it into the Roughness channel of Universal Material. The Reflection map is attached to the Specular channel. I don’t know if this is correct, just something I read while doing a quick internet search on converting Poliigon materials.

I used the Octane Falloff node with the two provided color albedo textures. Since the two materials were so close I added a color correction node to one of them to give it a more distinct shade so it would be more noticeable in the falloff. I’m not really that experienced with the Falloff node so I’m not sure I used it to best effect (I did make the skew factor a bit more extreme so the effect would be more apparent).

I also added a texture environment at a low level to give a bit of ambient light. And I removed the Cycles compositing nodes you had in there as they were interfering with the Octane rendering.

Just post if you have any more questions.

reason why it doesn't work cause material converter only converts simplest material setups - just a texture straight into principled bsds - and the setup you have has groups and - if there's anything after a texture the material converter will not be converted - only thing that could work is to bake beofore converting..

..other than that, octane team should make a better converted like they did for 3ds max - which converts a few material types - this one should at least be more straight forward

Thank you so much @pegot!
