Blender 3.0 Hair Add-On 2021 | 3D Hair Brush Update

Hi, everyone welcome to vfx grace recently, we've already updated 3d particle brush 1.6. Here are two amazing functions: roughness curve and random thickness. It'S very helpful for us to create a realistic and organic hair. Now, let's get started, let's do a round over compiled version. So just click and open it, a simple scene, gets ready. We find the children tab and then fold it in roughness. Here is the first function. I use curve to control uniform end point and random. Roughness is generally used to add fine details, but you may learn: roughness controls the whole hair. That is where not a lot to adjust a certain part of one hair separately. Exactly this function will do, let's start off with uniform, set the size to 0.05 and uniform to 0.02 by default. The hair is bent evenly, let's try the curve to bend the root less and the tip more check use uniform curve. Here a ramp appears the abscissa maps from hair root to tip the ordinance represents the intensity of the uniform, pull the left point down. We can see from root to tip the hair, gets curved gradually adjust the curve further as needed through a curve. We can tweak the intensity freely, pretty convenient and intuitive then end point the same principle actually bring up the end point and reduce the shape a little bit. You see, i just want the end point to work on the middle part and exclude the tip and the root. Let'S get to it, put both points down and add points and raise it up, adjust the curve further, as per your reference, cool, very handy right and next random in grey's random. Suppose i want the random work stronger near the root and weaker near the tip. Let'S make it dig, use random curve. Put the right point down then adjust the curve a bit okay done with it. Let'S see the comparison between before and after all, right, let's move on to the next function, find out the hair shape and unfold it. After use radius curve, we updated the user diameter random by default. There is no way to set random thickness for the hair in one particle system. Its diameter random. Exactly takes care of this concern. Here'S the demonstration and check it first: okay, the hair reveals random thickness diameter seed, start and threshold. These three parameters give us final control. First, diameter seed is just a random seed. I believe you got it then start controls the random intensity of thickness. Keep your eyes on the hair. When i increase it, the random intensity of thickness gets lower gradually. The reason one all the hairs return to the original thickness then threshold, it controls the proportion of the hair in random thickness by default is zero or the hair is of random thickness when increasing it. The hair in the original thickness is getting more the reason, one all the hairs return to the original thickness and when reducing it more hairs approach the finest shape until all the hairs become the finest shape. Alright, let's adjust the hair with this function, set the threshold to want its value and then change the start to get the proper random intensity. This function helps us out to easily achieve a hair shape, with all the hairs in different thicknesses, with greatly improves the efficiency that we groom a complicated hairstyle. Alright hope you like the new functions, thanks for watching
