Oh wow that is such a fantastic explanation! Thanks ever so much Dr Sassi, I'll let you know how my project goes

Hello,

How can I use the Voronoi fracture to break an object into two equal halves? I've used it many time before but in the past I've always been happy with the random breaking and multiple pieces. This time though, I only want two halves with the object being split horizontally. I've tried reducing the points to give me only two pieces but I cant make it so that the break is along the horizontal axis. I also want have random jagged edges of the break.

@ericsiegel Hi, thanks that's very helpful. Yes in my case the end result is only for making product imagery and videos of those products. I don't need to collaborate in any way with other companies on the 3D side of things, it's purely all about making them look as good as they can for promotional purposes. I think I should experiment doing them much larger and see if it makes things easier, thanks.

Hello,

What's the best advice for the size and scale of models? I've seen it said in some tutorials that its better to model at real life scale, however I've seen some where people have modelled at a much larger scale than reality.

In my case, many of the products I need to model are very small in reality and I've always modelled at life size to try and maintain as much accuracy as I can, but sometimes I feel its very difficult to get the lighting to look good at such small sizes, and sometimes the materials too. So is modelling small objects at a larger scale recommended or is it better to keep everything at real life scale?

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.

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
