I've learnt how to do black and white renders in Iray, but I was wondering how they could be achieved in 3Delight?

Although this isn't the answer you are looking for, could you simply use your graphics editor (photoshop, etc) and convert the image to greyscale? It's super easy to do.
You do have far more control in photo editor software, not just in converting to grayscale, but in adjusting the contrast and exposure, lightening and darkening certain areas, etc.
I was hoping to do black and white renders because, in Iray, they finish rendering in 10-15 minutes. I thought it might've been the same with 3Delight renders. Plus, I'm really into rendering black and white pictures at the moment.
The photo editor program that I use doesn't have a good greyscale option (or at least, I don't think it does).
In all the reading I've donel on 3Delight, I don't recall any way to remove the colour. I think you'd have to go right to the models and change the textures, and then you're back to a photo editor. Almost all photo editors have some way of desaturating the colours; maybe Google the name of your software and add "convert to black and white" or similar. You could try free software like Gimp, but I appreciate that's a whole new learning curve. Is there a reason you don't want to just stick with iray? I'm finding I'm using it for almost everything now.
I think one of the AoA cameras let you render b&w.
And if you use PWToon, pretty sure there are easy presets for that
...I believe that function (Colour Camera) was broken in the 4.7 update.
I think I've used that camera. I know there was a fix for the cameras because I used that so that I could use the cameras in DS 4.8. I just don't know which cameras it fixed, all of the or just some of them. I haven't reinstalled them in my new setup in DS 4.9, yet, so I'll have to track that down and see if it still works.
Also, I think one of the presets for LineRender9000 also has a B&W preset, too, but I'm not positive about that. I'm still playing around with that and learning everything it does.
this is what i do in D|S 4.8 using the aoa Fog camera in place of the colour cam. no post other than crop and sig in the expample picture . all in all took a couple minutes to render, YMMV depending on lights ect.

the thing is, the world is in colour or at least perceived to be by the cones in our eyes, the black and white image is how the film emmusion interprets it which is why you will find most digital photographers as opposed to film ones in fact shoot in colour and desaturate the image afterwards, though cameras do have a black and white setting, information is lost saving to file that way that can be used later in postwork to enhance the resulting black and white image,
The difference you are seeing is probably more a result of using a biased renderer than the desaturation process.
That's very good, @DireBunny. I love the result you got.
If you don`t like your program`s grayscale options, maybe you could take a look to Google`s Nik Collection. They are free and work either as stand alone or as Photoshop plugin.
The Silver Efex Pro is all about black and white. It has lots of cool presets.

Second the Silver Efex. It's really good.
Thanks , but too bad i just found i can't do it anymore if I try it with a new set up. it still works if i load up this set up from my old scene, but if i make a brand new scene and load in teh cameras, it wont work, weird .
