You cannot create a realistic 3D project unless you have clear conception about the soft images. You need to know how to create them via CG and how to render them to get the most realistic output. Hair is one of the vital soft images without which most projects would remain incomplete. But you cannot deny that rendering hair kills half of the time of a project. So, here are some tips on how can you save time while giving your CG image the most realistic hair.
Reconsider the appeal
Make a rough sketch of your 3D character with special attention on the hair. Once you have satisfied yourself with the hairstyle that will fit the CG character, think of ways you can reduce their numbers. One convenient solution for you is to decrease the number of strands but increase their thickness. The overall impact will be just the same as you have wished.
Do not overdo it
While following the first tip you must always remember that making the hair strands too thick can be a hurdle for you. It will cause flickering! Moreover, seeing a number of preview files before the final output will be problematic as the process of soft image rendering will become extremely slow. Remember this tip; the hairs should be thicker but fewer.
Be careful while using strand multipliers
A number of 3D artists think that working with strand multiplier will give their CG characters the desired look they want. They tend to increase the value of the strand multiplier to achieve the desired appeal. Unfortunately, this is not true! The more you increase the value of strand multiplier, the more time it takes to render your file. But this never means that either your 3D character must always be bald or have very scanty hair. The better way you can adopt to make the hair look voluminous is to concentrate on render hair and increase their numbers. This practice will not kill your rendering at all. Plus, it will give your 3D character the exact look you want!
Work in small clusters
Whether CG animals or human beings, the expert suggestion is that work in small clusters. To be specific on this, do not use a single cluster to create hair on the head or skin of your CG image. Rather, break it up into small clusters and apply hair separately to each cluster. This will help you in achieving your desired effect. Plus, you can be assured that it will not make the process of rendering an extremely time consuming one. One more benefit of this expert technique is that styling the hair of your 3D character will be much easier now. What more, following this tip will give you the freedom of changing the hair style of your 3D character whenever you like!
