Is the mirrored object an instance ?

Frankly, I have no idea what I'm looking at. Try to post a test scene explaining what is the problem.

Mirroring an object in Blender does not flip the normal faces. Not in my experiences. I've mirrored twigs many times for variation and Cycles materials do not flip the faces from backside to frontside. The first time this happened for me is mirroring and using Lux materials. If the normal is not fl...

Have you addressed the issue about mirroring? When the objects are mirrored the faces change from frontside to backside.

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)

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

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 term bombing refers to the Steve May's Renderman shader. Now Randomized Bitmaps Map in 3ds Max 2018. Look at https://developer.download.nvidia.com/b ... _ch20.html

Interesting. It should be easy to add.

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.

there are any options to texture bombing for foliage or dirt for landscapes?

I have frankly no idea what texture bombing is

Can you post/link an image to explain what you are aiming for ?

I am interested in light without reflection influence and I don't find a way. This kind of lights are important for lamps and artistic control (1 light for illumination and other light-mesh with the form of the real one for reflection of the scene materials). This kind of problem is usually handled...
