Hi Dr Sassi,

Just to say I got my project done using the technique you showed me, thanks again its very much appreciated

Hi Dr Sassi,

Oh dear it seems I didn't notice the selection That's why it looked different on my model, I'm such an idiot
Once again thanks so much for your advice, I was pulling my hair out on this one.

Kind Regards

Hi Dr Sassi,

Wow that's amazing! It's pretty much the result I'm after. I just need to make a few alterations to mine to get it to look the same. On your model in the example, that's practically there what I need, but when I put those materials on my model, the bright green colour is too strong and doesn't look as transparent as it needs to be on the flat surfaces. Is it possible to turn down the effect of the bright one, rather than turning it off?

I haven't encountered these RS Open PBR and Ray-Switch nodes yet, I will need to read up on these and do some study on them Thanks very much for your advice

Kind Regards

Hi Dr Sassi,

Thanks for the advice I didn't know about Bloom, that could be very useful in future.

I've still not managed to nail the material yet. I've almost got there but not 100% The plastic I'm trying to emulate is transparent with a slight colour. On the large flat surfaces the colour is very weak, but at the edges the colour is much stronger, almost as if the light is bouncing around inside and exiting out of the edges and concentrating the colour. It does this in ambient room light but it really looks like it's illuminated from within, almost like it's radioactive!

The attached image is a sample of it that I took on my table in just normal room light.

I tried using Transmission and set the absorption colour and distance according to the manual, and it almost gets me there but, on mine the edges are dark and not bright like the real thing. I tried putting a bit of luminance in but it makes the whole thing look illuminated (not just the edges) and adding glow just creates a glow around the outside of the object. I'm not sure where to go from here?

Kind Regards

Hi Dr Sassi,

Thanks for these, that certainly gives me some more avenues to explore. I didn't know about the mesh checker so I had a look. I didn't understand a lot of what it was reporting, and how I could go about fixing it. It did report that there were lots of bad polygons, but unfortunately I couldn't see how I could correct them, the mesh from the conversion looks quite messy. For now I've got by with retouching the blemishes on the still shots in Photoshop, although this will be a problem when I need to animate them. My best solution will be to remodel them from scratch in Cinema, if I can just get the time to do it

Kind Regards

Hello,

How can I replicate coloured translucent plastic that appears to glow at the edges? We have this plastic material that almost looks as if it's being illuminated from within and the edges appear to glow, even though it is only the ambient room lighting illuminating it. I'm doing this in the standard/physical renderer and I've tried playing with transparency and the absorption colour. It almost gets me there but it doesn't quite achieve the glow effect at the edges. Any tips or advice would be much appreciated thanks.

Kind Regards
Dave

Hi Dr Sassi,
Thanks for your advice. I'd love to share one of the models in question but it is a product not released yet so I might get in trouble It would sure make it easier if you could see one. I do always try to model as much of them myself as I can, it does produce much better results modelling from within C4D. It's simply down to time constraints really why I can't do all of them, my boss gets CAD files from manufacturers, I think they use Siemens NX . I convert them to OBJ and then bring them into C4D. Do you have any tips or advice for getting better exports? Is there a better way? Many thanks.

Kind Regards
David

Hi Dr Sassi,
Thanks very much this, I had a go at it on one of the actual models that I have to work with. I found that the geometry makes a big difference as to how well it worked. Some of the models aren't made by me, some are sent by the manufacturer which are converted from CAD files so they don't always work that great, unfortunately I don't have time to re-model them

Kind Regards

Hello,
Where is the correct place to put a surface imperfection image in the standard/physical render materials? I have a transparent material that I want to have some surface imperfections on, such as the si-v1_smudges_05_15cm_1k from the assets browser. I've tried putting in various places in my material but nothing ever shows up.

By the way, I see this sort of thing looks a lot easier in Redshift with the node based materials but as yet I can never get what I want out of Redshift, things just don't seem to work for me. I'm a good few lessons away from switching over yet so in the meantime I need to do it the standard and physical renderer. Thanks.

Kind Regards
David

Hi Dr Sassi,

Oh that's great news! I don't have any plug-ins so I should be safe. I'm still struggling with the basics so plug-ins is advanced stuff for me haha! Great to know I can safely delete the old ones and save on some disk space, and to be able to double click on any file and open with the right version Thanks Dr Sassi

Kind Regards
Dave
