Hello!The most rational and correct way is to go to the store, buy a package of nuts you need, remove all stickers and sfotkat from it. Then, based on this photo, create a texture and overlay it on the package.So I did about the same when I did the subject 3d rendering of shrimp packing:
This is the most competent solution. You only need to strongly prideretsya to say that this is a flat texture, and not bulk shrimp in the package. Alternatively, you can make a model of nuts in the form of packaging, but cut it right in the texture of the nuts and slightly pulling them to the volume. This will resemble a flat chocolate with bulky nuts slightly squeezed out of it:
And on top of the model, put a crochet around so that it envelops the nuts but does not stick to them in a dense one😁 Speaking of the way that you want to hear, namely literally about pouring 3d models of nuts in the volume of the 3d model of the package, then this is the most ungrateful undertaking. This can be done by a solid-state reactor built into 3ds Max or a particle system. But the result of their work will be so unpredictable and do not control that you are taken with the selection of the necessary parameters for longer than with the laying of each nut manually. You can find compromise options, for example, when you roughly pour a reactor, and then gently manually manage those objects that will come out for the desired volume. You can see the result of this work on the example of a 3d model of cans with pasta. If there are a lot of nuts, and you still do not know how to use the reactor, then forget it. Option with the texture, the most acceptable😉
I 3d visualizer and modellinngom not do it, so I do not tell you how to do the model for me of making a professional 3d modeler 😁
I can only say that it is a render grid with TurboSmooth in Isoline mode , so all the polygons are not visible, and the package makes the tool Editable Poly.
Nevertheless, we have the theme of poly modeling in the Max 3ds , where you can ask relevant questions😉
