I can probably extend the concept and have a "flip option" for all asymmetric Lux materials.

Is there anything ready to test for this?

I haven't yet written the code.

I'm working on this.

The backside seems to be extra glossy. I have tried the same settings for each, and the backside is different.

I'm trying to reproduce your problem but I'm unable at the moment: can you post a test scene ?

Here are the two issues:

1) The backside material is glossier than the frontside.
2) The sides switch when mirroring the objects.

What is the maximum file size that we can upload here? Not even a 9.43MB file will upload?

It should be 10MB, the problem may be in an not recognized file extension, you can try to .zip it.

Zipped file is 8.21 MB. It won't upload either.

As far as I remember it should 10MB but it may be only for images. You can use Google Drive, DropBox, etc. and post here a link.

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.

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"):


Once you have done that, you should get the sane results.

@B.Y.O.B: BlendLuxCore seems to leave the default values for the back face if the "Double Sided" option is not used. This is probably a bug and I assume people expect to have the same parameters both for front and back face.

Fixed. I had a wrong assumption about how the properties of this material work.
