paint skin weight. /This week’s model issue was very eventful. At the weekend the model suddenly blew up at home while painting skin weight. It needs to be changed. I think I need Nick’s help.

The case of the first picture is mainly because there are problems in the previous topology and the weight is not properly brushed, leading to model damage. But after Nick fixed it and I re-brushed the weights 4 times, my model was fixed. I am now very proficient with brush weights.
After you’ve done that, it’s time to finish the expression part. The shape editor is used here. Animation of facial expressions by different adjustments to the five features.

This week will focus on mapping and animating the finished model. The most challenging part of the texture of the whole model was the texture of the basket. It was not a solid color, so you had to find the corresponding material and unroll it and then stick it on the model.
For the balloon texture, a soft but slightly reflective material suitable for balloon fabric in hypershade is selected.
A metal material was selected for the gas tank, and different colors of the bottle were mapped separately.

After finishing everything with the model, Nick showed us how to animate the balloon, which wasn’t too difficult. All we need to do is put a sequence frame on the time series after moving the balloon. Finally, the export is complete. I think exporting is a very important thing. Because I made some errors in the export Settings, there were some problems after I put the files into nuke. Note the different export Settings for different file requirements in the next exercise.

The modelling of a hot air balloon, learning some basic techniques of modelling. The balloon is part of nuke’s balloon operation. Compared to the first two models, this model is much more detailed than the first two models, and involves some new content based on the basics. For example, rope making.

curve in the image on the left is one of the many tools used in this modeling. I’m going to draw the radians that we want and then I’m going to move it, stretch it and then I’m going to get the radians of the balloon’s ball, and the radians of the rope, and the states of several strands of rope stacked together. This is a great and useful new skill.

This is the gas tank part of the hot air balloon. I refer to the details in figure 1. It was not difficult to make this gas tank. poly model was mainly made by stretching, extruding, enlarging and shrinking.

This is the prototype that is basically finished, after each part is modeled and put together. It’s kind of like playing with Legos. In the modeling of this model, I learned how to make folds and radians for some soft objects that need radians. You can make the model more detailed in the next exercise. Because this exercise content does need to review the part. Not familiar enough with the application of the newly learned content.
