Re: TwoSided material

Thank you for taking the time to educate me on this!

BTW: I'm the person who contacted you about the PolarGrid project many months back. After a creative hiatus, I'm back on the project again.

Re: TwoSided material

You have taught me something! The object was negative in the X direction. Once the scale was applied the normals flipped. It's interesting to see how Cycles and Lux materials treat this scenario differently. Cycles materials leave the normals direction until the scale is applied, while Lux materials...

Re: TwoSided material

Is the mirrored object an instance ?
No, it is a duplicate (Shift D)

Re: TwoSided material

The normals do not flip on the mirrored object, but the frontside/backside material switches in Lux. This does not happen in Cycles (Top render in previous post).

Below shows the normals of the mirrored object.

Lux is switching the frontside/backside material on a mirrored object.

Re: TwoSided material

Referring to previous post, if it is not obvious, the top image is Cycles and the bottom image is Lux. If the normal is not flipped, material will not be. If it is flipped, the material will be. If you select, inside Blender, the original object and the mirrored one, how do the normals look ? The no...

Re: TwoSided material

But isn't that expected ? I mean it is the normal of the surface to be flipped by the mirror operation (i.e. it is not related to LuxCore, it is just what Blender does) :?: Mirroring an object in Blender does not flip the normal faces. Not in my experiences. I've mirrored twigs many times for varia...

Re: TwoSided material

Actually, it is the definition of your material to be asymmetric, you need to click on "Double Sided" and to use the same parameters for front and back face ("BF"): Yes, this was the issue with the extra glossiness! Have you addressed the issue about mirroring? When the objects are mirrored the fac...

Re: TwoSided material

The "Two-Sided_Issues-NoImages.blend" file demonstrates the two issues. Can you download and see if it is benefitial to you?

The full file I attempted to upload has the image textures packed in the blend file.
